Photosynthesis Play
Photosynthesis seems nothing short of magic: a little carbon dioxide and water, add energy, and poof, you get food! A thorough, collaborative lesson teaches youth the process of photosynthesis thanks to a skit they perform with a group...
Curated OER
Diurnal Cycling Experiments
Students carry out an experiment to monitor diurnal fluctuations in dissolved oxygen, carbon dioxide, pH, and water temperature. They determine the CO2 and pH of the samples (and optionally, dissolved oxygen). Students complete their...
