1. Water xylophone: Find 2 chopsticks and some glasses. Fill each glass with a different amount of water, and you have a xylophone. While my kids enjoyed this activity, I prefer listening to them play on our keyboard. Reminding them to strike the breakable glasses gently took a lot of the fun out of the activity. If they want to repeat it, we’ll use something studier, like mason jars.
2. Salt pendulum: This one took a bit of time to set up. And it didn’t have as big of a wow factor as I had hoped, most likely because we’ve seen the pendulum snake and sand graph at the Exploratorium. However, there is something about tweaking and improving the pendulum when you make it yourself- how far should you swing the pendulum back, how high and how fast should you make the salt fall, and how should you put the sand back in the cup to easily repeat the experiment again and again.
3. Hair dryer and ping pong balls: This simple activity was a hit. Our kids love the floating foam pieces at Curiodyssey, so I can’t believe it took me 6 years to do this activity at home. So simple, yet so much fun to see what keeps the balls floating and what makes them fall.
4. Tea bag rocket: When I saw this online, I realized it may not be an ideal indoor activity. However, when it is too dark or cold outside, it is a very simple and very impressive 5 minute experiment. And, if you drink tea, you probably have everything needed right in your kitchen.
5. Cup tower: Can you make a tower of cups strong enough to hold a person? Our youngest especially loved this project as she was able to stand on top of the tower and be the tallest kid in the room.
