Kinetic energy is energy that an object has because of its motion. An object that is moving fast has more kinetic energy. Potential energy is energy that an object has because of its position. An object that is up high has more potential energy.
Hunt around outside for something that has kinetic energy and something that has potential energy. Take a picture or video of what you found and tell us about their energy! How many different things can we find?!
Let’s find out! Choose 2 or more of the methods below and test how well they work. Show us your results in the comments below! Which method do you think works best?
You need: paper, a white crayon, watercolor paints, paint brush, cotton swabs, lemon juice, hair dryer, baking soda, water, grape juice, cups
Method 1: Use a white crayon to write a message on a piece of paper. Paint over the paper with watercolor paints to reveal the message.
Method 2: Dip a cotton swab in lemon juice and use it to write a message on a piece of paper. When you are ready to read your secret message or show it to someone else, heat the paper by holding it close to a light bulb or using a hair dryer on the hot setting.
Method 3: Measure equal parts of baking soda and water into a cup. Stir until the baking soda and water are completely mixed. Dip a cotton swab in the mixture and then, pressing firmly, write a message on a piece of paper. Let the message dry completely. Pour some grape juice into a separate cup. When the paper is dry, dip a new cotton swab in the grape juice and rub it across your message. The hidden message should begin to reveal itself.
Method 4: Research some other secret message solutions and test them out!
Observe means to use your senses to gather information. When you watch something you are using your eyes to observe and learn.
Watch the video below and observe the number of birds that are at this pond. Play the video again. Observe carefully. How many birds do you see? Did you miss any the first time? Tell us how many birds you observed in the comments below! Then record your own video and ask us to observe something in it!
Think you can build a tower as tall as yourself? Let’s find out! Start by gathering materials to make your tower. Good materials could be blocks, pillows, rocks or anything else you might find. Be creative! (Be sure to ask permission to use the supplies you find!)
When your tower is done, share a picture and tell us how tall it is! Did it fall down a couple times before you got it just right? How did you stack your materials to make a sturdy tower?
Set a timer for 5 minutes. Pick one window in your house and look through it to hunt for things that are blue. Set the timer for 5 minutes again. This time, pick one cabinet in your house and hunt inside it for things that are blue. Did you find more blue things outside the window or inside the cabinet? Post a picture of what you found and tell us about your treasures!
Go outside and hunt for the prettiest, most unique flower you can find. Take a picture, then post it and tell us where you found it in the comments below. Let’s see how many different kinds of flowers we can collect!
Density describes how matter is in a certain amount of space. If you have two objects that are the same size, the object that is heavier is more dense. It contains more matter in the same amount of space.
Hunt around your house or outside for two objects that are about the same size but have different density. Post a picture of what you found and tell us about their density! Which one is more dense? How do you know?
Make a model to show how far away the closest star is.
Light-years measure the distance between objects in space. Things in space are so far apart, one light-year is equal to about 6 trillion miles!
Proxima Centauri is the closest star to Earth (besides the Sun). Even though it’s the closest, Proxima Centauri is still about 4 light-years away.
Find something you have a lot of that you can use to represent trillions of miles. It could be Lego bricks, rocks, toothpicks or anything else small. Let one piece represent one trillion miles. If one light-year equals about 6 trillion miles, how many pieces do you need to represent one light-year? How many pieces do you need to represent the distance to Proxima Centauri? Line up your objects to show the distance between Proxima Centauri and Earth. Take a picture of your model and share it with us in the comments!
Choose a window in your home. Grab a piece of paper and some colored pencils, crayons or markers. Watch through the window for a few minutes. Try to notice small details. Do you see any patterns? Is there anything out there that you haven’t noticed before? Draw what you see through your window. Then share your drawing with us in the comments!
