Teaching Biology Through Problem-based Activities
Pupils plant seeds and observe the life cycle of the organism. They experimentally research the effects of radiation on seed growth. Students determine the effects of environmental pollutants on harvested seed.
Curated OER
Where Do Weeds Grow Best?
Student design an experiment in order to determine where weeds grow the best. Through data collection and observations, they discover optimum conditions for weed growth, conditions that make it difficult for weeds to grow, and create...

What Does It Eat?
Young scholars use crickets, mealworms, and pill bugs and observe what they choose to eat. In this science lesson plan, students record data, create graphs, and do a write up on what they see happening.
Curated OER
What Do Snails Eat?
Young scholars conduct a food choice experiment with snails, recording the results on a chart to determine what snails eat. In this what do snails eat lesson plan, students color a picture of snail anatomy, perform the experiment with 3...
