Grade 7 Week 7: "Simple" Invertebrates

This week we shift gears from plants into animals. As we have done with plants, we want to again showcase the vast diversity of living things these next few weeks.

Give us a few examples of how invertebrates adapted for survival?

Freshwater Hydra (Cnidaria) in our class tank.


Freshwater Flatworm(Planaria)


While we are on the subject, while you are studying the diversity of living things why not take another look at some of the EC Challenges like the birding photography or the insect collection. You are also more than welcome to give a few suggestions on similar projects that showcase a diversity of living things. All are done just like we did the herbarium: collect and describe.

Week 7 contracts can be found here. Over the next few weeks, with WKCE testing and assemblies, schedules will be different. So, this weeks contract will be spread over the next two weeks, due November 12.

Carissa,

What species did you pick?

Again, the contract is due at the end of next week, spread out because of the WKCE testing, play and other assemblies.

I learned that the are more invertebrates then vertebrates and most of the invertebrates are small.

they can change shape to fit into small spaces and cnidarians have tentacles filled with venom for defense and hunting and some can change size too

Some invertibrates change color to blend in with their surrondings. That is how they escape predators adn capture food.

Some invertebrates can change its shape or color of its body to protect itself from other animals.
