Chemistry on SciFri

Chemistry is fun!

While LE has been into physics and biology, this was our first ‘official’ foray into chemistry. I have talked about the science we do in this post.

Today’s activity was to find and discuss the states of matter: solid, liquid, gas, and plasma. (In case you were wondering, plasma can be shown in a plasma ball or a fluorescent light bulb. The glowing is actually caused by glowing plasma. In nature it is seen as lightning and the stars/sun.) DH also talked about Bose-Einstein Condensate. (JGI!) We filled balloons (solid) with water (liquid) and gas (air).

We also wrote these words up on card and put them on the wall. This is new for us, but something I have been trying to do more often as both a vocabulary building and reading practice exercise. It’s also something LE enjoys, as he loves to go to the wall later and ask questions about the words.

The experiment was to explore the weight of  eight different but similarly sized items, introducing concepts of density.

But the hit of the day was the periodic table videos! I showed him a periodic table, then let him loose on this site. I love this site for visual spacial learners! It features a periodic table, and each element is linked to a short video about it. The videos are well done. Each is very different and might contain experiments, stories about the discovery of the element and how it is used in real world applications or in the human body. The presenter has a sense of humour a lot like mine.  (Is that good or bad?)

I wouldn’t say LE got everything in those videos, but enough to really enjoy them, and for me to have a hard time getting my computer back!
