Lava Layering: Making and Mapping a Volcano
In this activity, learners discover how geologists use stratigraphy, the study of layered rock, to understand the sequence of geological events.
Rainbow Density Experiment
In this colorful activity (page 6 of the PDF), learners will make a multicolor density column by using different concentrations of sugar solutions.
Comparing the Density of Different LiquidsAdd to list Details
Learners carefully pour vegetable oil, water, and corn syrup in any order into a cup and discover that regardless of the order they are poured, the liquids arrange themselves in layers the same way.
Test Density with a Supersaturated Solution
Learners create three solutions with different levels of salinity. They compare the density of these solutions by coloring them and layering them in a clear plastic cup and in a soda bottle.
Pollen TracksAdd to list Details
In this activity (on pages 30-36), learners simulate a dig for ancient pollen, to experience how paleobotanists study fossilized pollen in rocks to learn about early geological and climatological even
In this activity, learners mix several sugar solutions to investigate the property of density. Each sugar solution has a different density and color of the rainbow.
Changing the Density of a Liquid: Heating and CoolingAdd to list Details
Learners investigate how the temperature of water affects its density.
Rain Forest in Your RoomAdd to list Details
This activity (on pages 19-24) introduces learners to the rain forest's layers—emergent, canopy, understory, and forest floor—and has learners make paper lianas (vines that live attached to trees) and
