Nature's Air Conditioner
Young scholars observe the process of transpiration in leaves. They measure how much water a leaf gives off in a 24-hour period, calculate the volume, and answer discussion questions.
Curated OER
Density
Students work with a partner to record observations on various materials. Working together, they calculate the mass and volume of each material and then combine them and shake them for a period of time. In their journals, they record...
