The first week we really broke the notes down by talking about the 3 main kinds of fish.
- Bony Fishes
- Cartilaginous Fishes
- Jawless Fishes
This helped the kids categorize some of the fish they have already learned. We also ended by briefly talking about buoyancy and the amazing swim bladder that God has placed in most fishes! So incredible!
The last thing we did was complete the Ectothermic fish experiment. I was a super focused teacher and totally forgot to take pictures of this! It was pretty neat though. Here is what we did:
- We purchased 2 goldfish (we bought our at the local fish store for .25 cents per fish
- We collected 2 small fish bowls
- A desk lamp
- A large bowl filled with ice
This temperature change does have some effects on the fish and how it behaved or moved in the water based on if the temperature was warm vs. cold.
(you can find this experiment in the Apologia textbook on page 101-102).
Here are the items we collected:
- Paper clip
The idea of buoyancy can be confusing so before doing this experiment, we talked about how God designed Fishes to be denser than water. Density tells us how tightly packed the matter in an object is. So if it is very dense, it has a lot packed tightly into it so it would be "heavier" than an object with less matter packed into it.
If the item is denser than water, it would sink.
The kids realized after hearing this that if fishes are denser than water, they would sink! God gave the fishes a specially designed "Swim Bladder" to help them with this. AMAZING!
Stay tuned to see the post on how to make this ornament and also to check out the video we used in our class.
I'll end by sharing the last page we used. The kids who finished up early were given a chance to "design their own fish" and then share it with the class. There are SO many different fish and I can only imagine how amazing and fun it was for God to design and create all the fish in the ocean...even the ones we have never seen or have yet to be discovered!
