I was reading a recent Blog post about doing a science experiments. We did a couple of these and we thought we would add in our own notes, just in case someone was struggling a bit.
First one was called DIY Tornado In a Jar. It was a lot of fun to create, but there was a bit of a hurdle: you must use a taller jar, like a spaghetti jar – you can not use an oblong jar, such as a glass Nutella jar. The shorter the jar the more difficult it is to get it to make the actual tornado. 🙂
Second one was called floating egg. My kids thought I was crazy when I told them you could make an egg float, but sure enough it can! Make sure to mix the water to the exact measurements otherwise it won’t work. The kids would have done this one over and over if they had a choice!
Last one for these weeks was making a potato clock. The kit can be purchased here, or at World Market. Here’s the ubber super cool (according to the twins) thing about THIS experiment: it doesn’t work on humans, but it does work in tomatoes, lemons, apples, potatoes… the list is endless. We kept the clock going for several days. Until……..air started to ripen the apples, then all you had to do was insert the nickel and copper probes into an unopened part of the vegetable or fruit, and it starts all over again.
Enjoy the summer!
