I learned in science things on the body, ecosystems, diseases, animals, matter, how humans impact earth, climate change, plants, chemistry, about the earth, atoms, the periodic table, chemical formulas, energy, food webs, life and atp.

Each of these topics where interesting and challenging. The ecosystems had things on land and water. It showed me the life in it including plants and animals. this also goes for aquatic ecosystems. they have some of the things land ecosystems have but not much. 

Climate change is mostly made by humans even going from the stone age by little fires and forest fires. It happens now with cars, factories and more.  

DISEases are the worst by killing you from the inside to the outside. it can kill many or just a couple hundred. the black plague was bad by eliminating half the population.

An assignment i did was the intertidal zone where i learned about animals and high tide and low tide. There were many animals but i mainly liked the hermit crab because of the way it walked looked. I learned that its mainly in low tide because it can find small food on rocks or in little pools of water. they find abandoned shells to live in where they will hide if theres a threat. it gets eaten fish octopus and birds but eats microscopic mussels and algae and dead animals.
