Chemistry

Otter is keeping a chemistry notebook. Inside he’s keeping track of some of the experiments we’ve done using this lab report. He’s also doing some notebooking pages, lapbook elements glued onto colored paper and other printables. When he’s done with chemistry, he’ll have a nice notebook to browse through and remember the various projects he completed. Here’s the cover I made to slip into the front:

Here are some of the assignments he’s already entered into it:

This was a project from Christian Kids Explore Chemistry. Otter took a look at the ingredients of various items and wrote them down to see how “chemistry is in our home”. He noticed how some of the items had the same chemicals.

In the 2nd week of our study, he learned about chemistry tools, safety and measurement. I made him this lab sheet to record the data from a hands-on activity from C.K.E.C. . Otter learned that when you pour liquid from one container to another, eventually it affects the measurement. He also learned how to measure from the meniscus of the liquid.

Here’s a cut & paste vocabulary activity I downloaded from middleschoolscience.com.

He also made these lapbook booklets about the scientific method and pasted them onto colored paper:

Here’s another cut & paste activity that helped define solids, liquids and gas:

I’m also making use of BrainPop, one of our favorite online activities. I found this printable to go with the movie about solids, liquids and gases.

He also did some fun lab safety papers with a Sponge Bob theme. You can find the teacher’s notes here.

Here’s an activity he did examining various compounds and mixtures:

Otter isn’t just learning about chemistry. He’s still exploring other science interests, such as astronomy, on a regular basis. He pulled out this kit we forgot to do when he was studying WinterPromise’s Sea & Sky program and completed it the other day. He looked up the actual positions of the planets from this site, to make sure every planet was in its place.
Woe to the big brother who might move one of them out of the proper orbit!

The other day we read about plasma globes and did some experiments. Here are the pics. Warning: I’m not recommending you do what we did! These experiments could be dangerous and we were referencing websites and videos such as this one. In other words, don’t try this at home.

Otter got a fluorescent light bulb to light up, just by holding it near the plasma globe:

If you put a penny on top and then touch the penny with a nail, you can see a small arc of electricity:

Otter also got an LED light from his Snap Circuits kit to light up just by touching it to the plasma globe:

We also recently split water into hydrogen and oxygen. Dad put a lit match to the hydrogen we collected and we all got to hear a POP!

Another experiment Otter did was to figure out how to separate salt from sand:

Other recent things we’ve done in chemistry:

  • Learned about hydrogen
  • Distilled salt water
  • Watched an acid reaction
  • Put up a periodic table poster
  • Learned about lab safety with Sponge Bob
  • Learned about controls and variables
  • Went on an elements scavenger hunt
  • Learned about Antoine Lavoisier

I think Otter is in science heaven lately. Chemistry is full of fun experiments and explorations.

For history, Otter made some ancient Greek honey cakes:
