What are science projects with animals

What are some science projects using animals??? It is for 4th grade. It has to be with a frog, gecko or hamster though
no rude comments plz

For hamster :
-See what food is prefers..Why does it like this food?
-Make a maze for it, and see how long it takes for it to get through..Make different mazes, or use different hamsters.

For frog :
-What food does it prefer?Why does it like this food?
-How far it can hop, and how much it hops.


Gecko :
-Favorite food..Why does it like this food?
-What surfaces can it walk on, and what surfaces can it not walk on?Why can it walk one these surfaces?

I'm not sure if this qualifies as a science project (it's been many years since I've been in fourth grade)

you could dissect a frog or cook one or you can explain why a frog will jump out of a boiling pot of water while a frog that is slowly subjected to heat will not jump out and be cooked.

Not sure what you can do with a gecko.

Hamster you might be able to make some sort of maze.

Why does your teacher want science projects with animals?

I think that suggestion of cooking a frog to someone in 4th grade is pretty disgusting. Just to point that out.
Frog wise you could watch frog eggs develop and note the different stages of metamorphosis, then release them into a nice safe pond somewhere ::)

-what food does an animal prefer over another?
-what's the average inches per minute that a frog travels?
I hope this helped or at least sparked more ideas :)

if a frog prefers live or pellet food and why..... if the gecko is more active in uv lighting or in coldness
if the hamster
