Hey there! Are you feeling bored like Squeaks? Don’t worry, we’ve got some fun experiments you can try at home to keep you entertained and learning. Let’s dive into some cool science activities!
When it’s cold outside, we usually put on sweaters or blankets to stay warm. But did you know that animals like seals and whales have a special way to keep warm? They have a layer of fat called blubber that keeps their body heat in and the cold out.
You can try a fun experiment to see how blubber works using shortening, which is a type of cooking fat. Here’s what you’ll need:
Fill one bowl with ice water. Then, fill one plastic bag halfway with shortening and place another bag inside it. Squish the shortening around to create an even layer. Put one hand in the shortening bag and the other hand in the ice water. You’ll notice that the hand in the shortening stays warmer, just like blubber keeps animals warm!
Have you ever wondered what happens when you let go of a blown-up balloon? It zooms around the room! You can use this idea to make a balloon rocket. Here’s what you’ll need:
Tie one end of the string to a chair and thread the other end through the straw. Blow up the balloon, pinch the end, and tape it to the straw. Let go and watch your balloon rocket zoom along the string! Try experimenting with different balloon sizes to see how it affects the rocket’s speed and distance.
Want to send secret messages? You can make invisible ink using baking soda and grape juice. Here’s what you’ll need:
Mix equal parts baking soda and water to create your ink. Use a cotton swab to write a message on the paper and let it dry. To reveal the message, paint over it with grape juice. The grape juice will react with the baking soda, making the message appear!
Did you know you can make your own cartoons? A zoetrope is a simple device that creates the illusion of motion. Here’s what you’ll need:
Cut strips of black paper and tape them into a circle around the cardboard base. Cut slits in the black paper and draw a series of pictures on the white paper. Tape the drawings inside the black paper circle. Spin the zoetrope and watch your drawings come to life!
These experiments are not only fun but also teach you about science in a hands-on way. So grab a friend or a grown-up and start experimenting. Who knows what amazing discoveries you’ll make!
Blubber Experiment Extension: After trying the blubber experiment, think about other animals that might use blubber to stay warm. Can you draw a picture of your favorite animal and show where its blubber might be? Discuss with a friend or family member why blubber is important for these animals.
Balloon Rocket Challenge: Once you’ve made your balloon rocket, try changing the angle of the string. Does the rocket go faster or slower when the string is tilted up or down? Write down your observations and share them with your class or family.
Invisible Ink Adventure: After writing your secret message, think about what other liquids might work to reveal your message. Try using lemon juice or vinegar instead of grape juice. What happens? Why do you think some liquids work better than others?
