Density and Texture of Soil
All soil is not created equal! A lab activity asks learners to collect and analyze soil. Specific calculations determine the amount of sand, silt, and clay in a sample and allow individuals to identify the soil texture.

Diseases
During a cholera outbreak, scientists presented two theories; one theory was based on miasma and the other on germs and contaminated water. The lesson looks at the scientific process for finding the real culprit.
Curated OER
Sands of Time
Young scientists take a close looks a samples of sand that come from three different beaches. They use microscopes to view the three slides, and make observations on a worksheet. At the end of the lesson, learners share their...
