Settling Rates of Different Size Particles
Young scholars discover how and why the settling rate of particles differs with the size of the particles. Using different soil samples, they calculate the amount of time it takes for a sample to settle in water for up to forty minutes....
Curated OER
Weeds on the Windowsill
Students study farming and reasons to control weeds. They examine pesticides necessary for the control of weeds and the damage to the environment. Through experimentation, students plant seeds in different soils and determine if seeds...
Curated OER
Wetland Wonders
Students describe the characteristics of wetlands. They demonstrate their understanding of the importance of wetlands to humans and wildlife and determine they are defined by the presence of water, and specialized soils.
Curated OER
Investigating Porosity and Permeability
Student describe porosity and permeability in sand, gravel, clay and potting soil. They experiment using different materials to discover the different porous substances and the permeability of the same substances. Students place data on...
Curated OER
Earthquakes!
Students experiment with the concept of earthquakes while completing a lab with marshmallows, toothpicks, modeling clay and firm Jell-O and rectangular pan. They explore what kind of soil earthquakes do the most damage in and how...
