Pool Boats is a simple, yet scientific activity to do with kids inside or outside of the home. This activity came about because my son had a fever and could not go outside. Although he had a fever, he still had a desire to play. So, we did this activity.
A week prior, my son asked me for a bathtub boat but we did not have one at the time. So, I started doing research on how to make a simple DIY boat at home and came across this activity at the library. We had coins and aluminum foil at home and my son said “Let’s do this now!”
I encourage you to do this activity outside! It is more fun this way, in my opinion! Additionally it is a great activity to teach your child about buoyancy.
Let’s Get Started!
Kiddie Pool or Bathtub filled with water
Four 12 x 12 inch (30.5 x 30.5 cm) sheets of aluminum foil
Fill the pool or bathtub with water.
Put a flat piece of aluminum foil in water, edge first, and watch what happens.
Crumble up the second piece of aluminum foil.
Drop the foil in the water to see whether it floats or sinks
Form another piece of foil into a boat to see whether it will float
Put coins into your foil boat. Determine how many coins you can add to the boat before it sinks.
Redesign your boat with another piece of foil to see whether you can get more coins in before it sinks.
My son decided to destroy the boat to see if it would sink.
The Science behind this activity
Buoyancy is the ability to float.
To make an object float that would not normally, your child has to change its shapes so it pushes out its own weight in water.
A flat sheet of foil is denser than water and sinks if you put in the edge first.
When you change its shapes to a boat, it pushes more water out of the way and can float.
Adding coins to the foil boat increases the weight of the boat, and when it get too heavy, it sinks.
The crumpled foil traps air inside the foil ball and makes it buoyant.
Tell your child that life jackets work the same way.
Life Jackets keep you afloat in water because it contains a lot of trapped air.
Other Activities to try
Test the buoyancy of other materials such as wood, plastic, and rock.
Compare what happens when you put a water balloon in the pool versus an air-filled balloon the same size.
It is warm outside and kids are going to the beach (where there is salt water) and the pool. Some kids may notice that they float better in salt water than in fresh water. After doing this experiment, your child will know why this occurs. Explore the difference in density between salt water and fresh water with this easy experiment.
Let’s Get Started!
2 Glasses of Water
Place a few ice cubes into one glass of water
Add a few drops of food coloring into the ice water.
Add several tablespoons of salt to the other glass of water and stir so it dissolves.
Add some ice cubes to the salt water glass.
Add food coloring to the salt water and see what happens.
Compare the food coloring in the fresh and salt water.
Why it Works:
Saltwater is denser than fresh water because the sodium chloride is dissolved in it.
Specific amounts of salt water is heavier than the same volume of freshwater.
When salt is dissolved in water, like at the ocean, the salt adds to the mass of the water.
The salt makes the water denser than it would be without the salt.
When salt is dissolved in water, as it is in ocean water, it adds to the mass of the water and makes the water denser than it would be without salt. Because objects float better on a dense surface, they float better on salt water than in fresh water.
One day, I was looking at the book, Crafty Science by Jane Bull. It has a bunch of STEAM projects for children to create at home. I showed my son the Invisible Ink activity and he said “Let’s do that mommy.” We looked around the house and gathered the materials.
I thought this would be a great drawing and writing activity for my son. He ended up writing numbers. This is a great project to expose your child to literacy and science. If your child is learning how to read, write words that will challenge them to use phonics or sight words. The science in this project is explained at the end of this post.
Let’s Get Started!
Paintbrush or Cotton Swabs
Iron (for adult use only)
Squeeze a lemon into a bowl
Write your secret message on the paper in lemon juice using a paintbrush or cotton swab.
Draw quickly in order to check your work before it dries. It does not have to be as dark as the picture below. My son insisted on going over the numbers numerous times so he could see it.
To get the message, an adult should iron the paper with a hot iron until the message comes through
This activity may stain your iron with brown spots. This happened to me. I was able to get my iron squeaky clean by following the video below.
Why this activity Works:
This works because lemon juice is an acid.
When it is put on the paper, the acid destroys some of the paper surface.
When you heat it up with the iron, the areas with the message turn brown first.
Milk also works with this activity because it is slightly acidic.
My son loves to play, build, and race his toy cars. One day, I asked him if he wanted to have a car wash after seeing this activity on the Internet. I remember looking at this activity and thinking this would be a great idea for a kid who likes cars.
I had several reasons for suggesting the car wash. First, this activity was a fun way to encourage my son to practice his penmanship. The weekend we did the activity, it was raining. I was trying to find something hands-on to do in the house; although, a car wash is really fun when doing it outside on a sunny day. Furthermore, I wanted to incorporate three things that interest my son which are cars, counting, and getting messy.
Our Car Wash incorporated fun and so many aspects of hands-on learning. I thought I would share this activity with you so your kids can have as much fun as my son.
Let’s Get Started
Big sheet of poster board or white craft paper
Cash Register or Play Money (You may also make your own play money)
Two Rectangular Plastic Containers
Have your child decide the Car Wash Prices.
If your child can write, have them write the car wash prices on the poster board or white craft paper.
My son decided to give each color car a different price.
If your child can’t write, you may create the Car Wash Price Sign for them.
You may have your child draw the various colored cars on the sign.
I created a template on construction paper to assist my son in organizing the Car Wash prices on the white craft paper.
Tape the Car Wash Prices to a wall where it is visible for customers.
Get the toy cars, cash register, wash cloth, and towels
Lay the towels on the floor if you are doing this in your home.
If you are outside, then you can skip this step.
Fill one rectangular plastic container with dish detergent and water halfway.
This is where you will wash the cars
Fill the other rectangular plastic container with water.
This is where you will rinse the cars.
Now the Car Wash can Begin!
Have your child role play the Car Wash owner.
You or your child’s siblings and/or friends can play the customers.
As a customer, get some play money so you can pay to get your car washed.
I started off with $30.00 divided into (10) one dollar bills, (2) five dollar bills, (1) ten dollar bill
Have your child say the following:
“Welcome to the Car Wash, how may I help you?
You will respond by saying the following…
Yes, I would like to have my yellow cars washed please.”
Then your child will look at the poster they made to see how much it costs to wash the yellow cars.
On our poster, it costs $2.00 to wash the yellow cars.
I had three yellow cars, so I gave him $6.00 with (1) five dollar bill and (1) one dollar bill
Sometimes I gave him more money than the cost of washing the car so he could practice his subtraction skills and give me change.
After giving my son the money, he took the cars and washed them.
He washed them in the soapy water container and then put them in the container with water to rinse.
Next he put them on the towel to dry.
We kept repeating these steps until all the cars were washed.
Another time we did this activity, I was the Car Wash Owner.
We have also done this activity where my son was the Cash Wash Owner for the red cars but I was the Cash Wash Owner for the blue cars.
In other words, we were alternating roles.
Tailor this activity to your child’s ability by doing the following…
Have your child wash only one car at a time so they don’t have to do any subtraction or addition.
Only give your child one dollar bills so they can practice counting by ones.
Make all the car wash prices the same to make things easier.
Subjects Learned in this Activity
Sort the cars by colors.
Make different prices for each color car.
You may also have a car wash with one color car like the red cars.
Adding the costs to wash multiple cars.
Subtracting when the customer gives the Car Wash Owner too much money and change is needed.
Multiplying the cost when multiple cars with the same price are needed to be washed
We had some cars that would float in the water and some that would not
We discussed that cars with less density than the water will float.
Cars with more density than the water will sink.
We reviewed the word buoyancy, which is the ability to float in water.
You may discuss the science of soapy water and how it cleans the cars.
Soap attaches to dirt and grease and causes it to be pulled off the toy cars and suspended in the water
My son was able to practice his handwriting skills in creating the Car Wash Price Sign.
Teach your child the importance of being nice and respectful to their customer.
Also ensure your child knows to clean the cars well so the customer is happy.
If the customer is happy then they will bring more customers.
Explain to your child that Entrepreneurs own businesses and their purpose is to solve problems or make things better.
A great business has happy customers who will tell others about their service or product.
Take your child to a real Car Wash and show them it is a Real Business.
Have fun with this activity and make this your own!
Spring is here and many kids are helping their parents and teachers grow plants and flowers. One of the most important jobs in growing plants is to water them regularly. My son helps my husband water the garden. As a result, by July, we have vegetables such as cucumbers, tomatoes, and green beans.
This Celery Experiment is great way to show kids how plants get water from their roots up to the leaves. At the end of the post, I will explain why this experiment works.
Let’s Get Started!
Glass Jar or Drinking Glass
Gather the materials
Cut about one inch off the bottom of the celery stalk.
Fill the drinking glass halfway with water.
Put a few drops of food coloring into the drinking glass.
Place the celery stalk in the colored water and let it sit over night.
Rip open the celery to see how the color travels throughout the stalk
You should see that the food coloring has traveled to the leaves.
Why it works:
When you water a plant, the roots absorb the water from the soil.
The tiny tubes in the celery or plant stem, called xylem, draw the water up from the roots like a straw.
This process is called Capillary Action.
Capillary Action happens when water climbs up the tiny tubes.
The water droplets stick to the walls of the tubes and go upward.
The water sticks to itself and pulls more water as it climbs up.
Capillary Action lets water climb up to the various parts of a plant through the xylem tubes in the stem.
Writing letters and numbers is a skill that many parents and teachers ensure their children possess. My son wrote his first letter, A, at 21 months.He revealed it to me through abstract artwork that left me in shock.
Now he is four-years-old and his writing has improved tremendously. However, I like to find ways to make writing appealing and fun for him. One way to do this is through making our household, when possible, our writing canvas. This means writing in the tub with bath time crayons or writing on our screen door with window markers.
Today I will show you how we used household ingredients to write and create art. The project is called Pan Frescoes. Frescoes is painting with watercolor on wet plaster on a wall or ceiling.
In this project, we make our wet plaster with cornstarch and water! Instead of painting on a wall or ceiling, we will do it in a pan. You may also choose to do this outside on concrete. Just remember to rinse it with a water hose when done.
In this book she talks about an experiment where some kindergartners in a school district received extensive instructions in reading while the others spent the same amount of time learning science.
The kids that learned science melted ice, observed thermometers in hot and cold places, played with magnets, grew plants and learned about animal life. Books and pictures were available for these children but no formal lessons in reading were held.
The school district learned that by the third grade the “science” children were far ahead of the “reading” children in their reading score. The reason is their vocabulary and thinking skills were much more advanced. They could read on more topics and understand higher levels of material. The playful, hands-on activities the “science” children did taught them analytical and problem solving skills and how to make connections in what they were learning.
So let’s talk about our exciting science experiment!
Today we will…
Blow Up A Balloon Without Blowing At All!
To incorporate literacy in this experiment, help your children read the Materials, Method, and Why it Works headings in this post. As kids are reading these sections, have them do the action. Children can use the pictures to help them read the words. If your children can read independently allow them to do so.
How to incorporate literacy in this experiment…
Read the Materials and Method sections.
Re-read the Materials section as you get the supplies.
Re-read the Method section as you do the steps.
Let’s get started!
Teaspoon of Baking Soda
Empty Water Bottle
Safety goggles (we didn’t have safety goggles so we used sunglasses)
Put on your safety goggles (or sunglasses).
Pour some vinegar into the water bottle
Vinegar should fill 25% of the water bottle.
Pour baking soda into the balloon.
Stretch the balloon over the funnel’s neck.
Take the teaspoon of baking soda and put it in the funnel.
Ensure the baking soda reaches the inside of the balloon.
Stretch the balloon over the water bottle’s neck.
Pick up the balloon and empty out the baking soda into the water bottle.
AFTER THE BAKING SODA GOES INTO BOTTLE, PLEASE BACK UP IN CASE THE BALLOON POPS.
The balloon popped when we did the experiment for the first time.
Safety goggles will protect your eyes in case the balloon pops.
Stand back and watch the balloon BLOW UP!
Below is a video of my son and I doing the experiment!
Why it works?
As the baking soda mixes with the vinegar, it creates bubbles of carbon dioxide gas that escapes into the balloon.
This makes the balloon blow up by itself.
If the mixture creates a lot of gas, then the balloon will get so big until it pops!
As adults, we most likely want to prevent children from getting sick. It disturbs their playtime and they often look helpless lying in bed during an illness. One way to keep kids healthy is to teach them how to prevent germs.
I have provided 4 FUN and SIMPLE activities that will complete this mission! These activities will have your child wanting to help with chores and pinpoint the importance of good hygiene.
Learn How to Teach Kids to Cover their Mouths in a Fun Way
Let’s get started by answering basic questions about germs/microbes.
How are germs spread by hands?
When you cough or sneeze, this is the lungs’ way of doing their job to force bad germs/microbes out. Some people cough in their hands if they don’t have a tissue. Coughing in your hands leads to germs being left there. When you touch anything such as a doorknob, pen, sink, utensils, or someone else’s hand, you will spread germs.
How can you prevent germs from spreading?
There are good and bad germs. You want to keep good germs and get rid of bad germs. Good germs can help make vitamins that your body needs. Foods that increase good bacteria or germs are asparagus, beans, spinach, and bananas.
One way to prevent bad germs from spreading is to cough or sneeze into a tissue or elbow. Furthermore, if you don’t cover up at all while sneezing and coughing, the germs can go really far. Some germs can travel 100 miles (160km) per hour and spread over 100,000 more.
Another way to prevent germs is to wash your hands frequently with soap. Soap helps to remove dirt and microbes. Hand washing should occur before eating, after using the bathroom, when playtime is complete, after using public transportation, or visiting public places.
How can kids prevent germs?
Germs can enter the body through the mouth, nose, breaks in the skin, eyes and genitals (privates). Below are 5 ways to prevent germs…
Using tissues to wipe and blow your nose.
Staying home from school when you are sick.
Keep hands out of mouth.
Do not use other’s forks, spoons, or drink from the same cup.
Teach kids to wash their hands.
How do you teach a child to wash their hands?
Have kids do the following steps to wash their hands…
Wet their hands with warm or cold water.
Use soap to lather their hands while singing “Happy Birthday” twice.
Scrub between fingers, on the backs of hands, and under nails.
Rinse well and dry with a clean towel.
Tip: Create a colorful chart with the steps above and display in all bathrooms.
This book is about an oval shaped microbe character named Min, who teaches children about germs, by going on an adventure. Min begins her journey ON the book and involves readers by asking them to take her various places.
For example, the book says “Let’s take Min on an adventure! See the circle on the next page? That’s where Min lives. Touch the circle with your finger to pick her up. Min is now on your finger!”
Taking your Child on a Germ Journey
During Min’s travels, she meets friends and takes them along the way. Somehow Min and Rae end up on the reader’s shirt! At each stop, the authors show children a microscopic view of their destination. Additionally, commentary from other microbes explain how they function. While Min and Rae on are the reader’s shirt, one microbe says “Can you give me a hand spreading this dirt around?” Another microbe says “We’re making this shirt smell.”
While Min and friends are on the reader’s belly button, one microbe asks, “Did I tell you about the time soap got all the way in here? Another microbe replies “I don’t like scary stories!” This book teaches children the importance of brushing their teeth, washing clothes, and taking a bath in a humorous manner.
At the end, the authors show readers what microbes really look like and where they can be found.
Let’s apply it with 4 FUN Activities!
Use the activities below to….
Teach your Child about germs.
Encourage them to help with chores.
Promote Hygiene and Self-Care.
I do these activities with my son and he loves it!
Create the Germ/Microbe
Have your child draw a germ/microbe.
Tell the child to give the microbe a name.
Have your child draw the microbe a friend and name it.
Tell your child the microbe is going to travel to three places…
On their teeth
On their hands
Tell your child you are going to get rid of the germs by doing the next three activities.
Explain to children that microbes get on our clothes and make them dirty and stinky.
While doing laundry have your child help you put the clothes in the dryer and washing machine.
While your child is handling the clothes say the following…
“Let’s get the Microbes off the clothes by putting them in washing machine.
Make it fun and urgent by saying the following…
“Oh no! The microbes are multiplying let’s put them in the washing machine quickly!
Make it into a race against the Microbes.
Explain to children that microbes get on our teeth and cause tooth decay and cavities.
Explain that cavities are holes in your teeth.
The microbes also cause your breathe to stink.
These microbes love sugars like candy.
In order to get them off, they must floss and brush their teeth.
While your child is brushing their teeth say the following..
“Hurry Hurry, the microbes are running because they know we are about to brush your teeth!
Let’s brush your teeth to remove them now!”
I hear the microbes saying, “No, No don’t brush your teeth! We don’t like the smell of toothpaste!”
When your child is rinsing their mouth and spitting, say the following…
“The microbes are down the drain and they are yelling “No, No!”
Explain to children that microbes get on our hands as we touch various things like the doorknob and sink.
We often touch our noses, mouths, and eyes allowing microbes to come into our bodies and make us sick.
We need to wash our hands to decrease our chances of getting sick.
While your child is washing their hands, laugh and say the following…
“We are going to get those microbes by washing our hands with soap!”
“The microbes are scared of soap so let’s keep scrubbing!”
When your child is rinsing their hands, say the following…
“The microbes are down the drain and they are yelling “No, No!”
“Yes! We conquered the microbes!”
When I forget to do these activities, my son usually asks me to play the Microbe Games!
Get creative with your children on how to remove microbes!
