Fish Diagrams

First grade ichthyologists observed fish in conjunction with their living and nonliving unit. Click here to watch fish.

All living things (plants and animals):

  • Move on their own
  • Reproduce (make more of their own kind)
  • Need air, food (energy), and water
  • Grow and change (life cycle)
  • React to changes around them (light, heat, sound)

After a lesson about fish body parts, life cycles, and habitats, each of us had a goldfish to observe up close. Is the fish alive? How do you know? This can be a confusing unit. Children often think water, cell phones, fire, and clouds are living. Is a stick or an apple living? Yes, they are classified as once living.

The ability to meaningfully interpret text features in non-fiction books is an important skill. As we observed our fish, we drew a diagram and added the labels.

When I was cleaning up, I discovered that one of my biologists had drawn a heart on the paper under her fish. I love living things too!

Pill Bugs (Roly Polies)

Six years ago, I purchased 30 roly polies. They have multiplied over the years, and we continue to use the offspring of those first pill bugs in the science lab for investigations. Look very closely and you will see baby pillbugs. Some of them are very tiny! The female pillbug carries the eggs in a brood pouch under her body.
