Kysa Question re: zero cost labs for high school biology

I am new to this board and found a post about labs for high school biology

I already have highschoolers and no financial resources for labs.

I really need ideas for stuff that I won't have run around, hunt down and buy. We're a no car family right now.

I have one son who is a naturalist by nature and he already reads fields guides and has his own binoculars and digital camera which he uses to take pictures of the wildlife in our back yard.

My other son has no interest in science whatsoever, but they both want to go to college.

We have an old copy of Abeka Biology and Bob Jnoes Biology textbooks. We don't have the lab manuals or answer keys

If you can give me some suggestions on how to manage high school biology w/labs, I'd appreciate it.

Feel free to email me

PS If you have ideas for high school chemistry, I'll take those, too because I also have an Abeka Chemistry text
