This is our photosynthesis experiment. For the next four days, this leaf, on our healthiest window plant, will be covered by 3 layers of dark colored paper. Nothing else is changed... the leaf is not damaged and still has access to air, water, and soil. The experiment will be to see if it is still the vibrant green at the end of our school week. Alex had to write up what we did for the experiment, a hypothesis about what will happen, and at the end, he will write a conclusion.
We have used quite a few books for this unit study already. The best (which we are still using) have been Trees by Mary Julivert, Berries, Nuts & Seeds, and Trees, Leaves, & Bark, (both in the Fun with Nature Take-along Guide series). The "Trees" book is a field guide. They whole thing is set up in two page spreads, much like a good encyclopedia.
Now we are on our way to the Festival of Trees downtown. Not quite related as they are ALL fir trees... but it will be fun anyhow.
