- finished reviewing the notes of factors affecting terrestrial and aquatic ecosystems
- considered the effects of seasons on lake and pond life in our handout (winter/summer stagnation and spring/fall overturn)
- did text book questions - pg. 107, Q's 1-4, 7 (to be marked!!)
Thoughts and questions:
- i like using the handout to do notes... that way you have the main points already there, but can add more details in if you like
- why does O2 dissolve in water at colder temps?
Above and beyond:
i went to Google and found why O2 dissolves at colder temps...
- it said that there is less O2 in the summer because warm water can't hold as much O2 and because the pond's O2 demand is more in warmer water
