Ecology
In this ecology instructional activity students complete a crossword puzzle that incorporates all of the ecological vocabulary in the word puzzle.
Curated OER
Germination Inhibitors
In germination experiment learning exercise, students conduct the following lab activity. Kids determine the effects of another tomato on germinating seeds. Students answer the following questions to analyze their experiment.
Curated OER
The Atmosphere and Flight
Students investigate evaporation and condensation, and apply the concepts to understanding cloud formation.

Serc: Rain Erosion: Does the Rate of Water Effect Erosion?
In this lab, students investigate whether the rate of water falling (rain) affects the amount of erosion (soil movement). This experiment could lead to further questions: how does grass or rocks effect soil erosion, does erosion lead to...
