You see, on the Tiny Planet of Technology, the floor is metallic and pretty smooth. But what would happen if the floor was made of carpet? Continue reading
Bing and Bong certainly learned a bit about just how powerful the wind is and how to have fun with kites. Now it’s your turn – let’s build a kite! Continue reading
Music can be found everywhere, even Water. Explore music with your child using a few simple household items. Let’s see if you can line up a chorus line as well as Bing did in A Chorus Line!
- 10 glass jars or bottles
- Sticky labels
- Spoon, fork or stick/pencil
- Food coloring (optional)
- Fill each jar with different amounts of water. Start with very little water in the first jar and continue to fill each jar with an increasing amount.
- Have your child strike the jars carefully with a spoon (or whatever object you chose). Make sure to listen for the variety of pitches!
- Help your child put the sounds in order from low to high.
- Once they are in order, label the jars from 1 (lowest) to 10 (highest).
- Mix up the jars — see what beautiful musical tunes the two of you can make together!
Extend the activity by asking your child to add or subtract water from the jars to see what happens. Does this change the pattern? Add food coloring. Does that change the pitches? Play around and explore together!
How It Works
The more water you have in a jar, the lower the pitch will be. You see, the sound vibrations you hear come from the jar, not water. So, as you add water it takes up more space — providing greater vibrating mass. The less water in the jar means there’s less weight to vibrate so the pitch is higher.
Health & Safety
- Encourage your child to strike the jars gently and supervise them at all times. Explain the dangers of glass jars and breakages.
Trying to get across that slippery slope was hard work. If only we had remembered sooner what our friend Science Jim had shared with us a few months ago about friction. So this time when Jim visited we quizzed him a bit more about how friction works. We did a cool experiment that really opened our eyes to the power of friction. But be warned, this little experiment is geared towards the older explorers, but if the parents take over the notetaking tasks younger ones can have fun too! Continue reading
Did you like how we used that magnet to catch our giant fish? I’m sure you’ll agree that the folks on the Tiny Planet of Technology have ingenious tools. The really great thing about technology can be made just about anywhere — including your home.
Yes, it’s true. You can even create a magnet in your kitchen! Science Jim dropped by and shared with us an easy way to create a magnet with a few household items. But before you get started there are a few things you should know.
One of those things is what causes magnetism? Electrons! Electrons are always spinning. The reason some things are magnetic and other things aren’t is due to the balance of the spinning electrons. Electrons are said to spin left or right. Continue reading
