Elodea Lab
Students observe the changes between elodea leaves placed in darkness and light. In this life science lesson, students experiment to find evidence of photosynthesis in elodea leaves. Students use indicators to detect the presences of...
Curated OER
Hormone-Induced Plant Propagation Lab using Carrot Root Cultures
Pupils evaluate the importance of hormones in living things. In this biology lesson, students experiment on carrots to differentiate how humans and plants reproduce. They collect data from experiment to answer analysis questions.
Curated OER
Investigation of Timbre
Students design an experiment to analyze the timbre of different instruments. In this physics lesson, students analyze the missing quality in sound. They discuss their results in class.
