Is soil structure an important factor in earthquake dynamics? Investigate soil liquefaction and how different soil types respond to earthquake movements. Are movements more dramatic in sandy/loamy or clay type soils? Which soil structures are most stable? Which are the most volatile? (MCEER, 2005)

Have you ever taken a step onto what appeared to be dry ground, only to find yourself ankle deep in mud? Yikes! When you walk through damp soil, it can be a very messy experience. How can you tell if soil is wet or dry before you step on it? In this science activity you will investigate whether the color of soil can help you determine how dry or wet it is.

Have you ever noticed how much work it is to dig a hole in really hard soil? It's much easier to dig a hole in soft, loose soil. But why is that? Soil that is hard and dry is often compacted, which means that it has been packed down, making it denser and thereby difficult to penetrate. Soil that has become compacted is not only harder for you to dig a hole in, but it can also be much harder for a lot of other organisms, such as helpful earthworms, to survive in.

What variables contribute to the properties of the soil in an area? Investigate the role of climate, weather, topography, time, parent material, vegetation, and biological and chemical agents on soil formation. How are soils characterized? There are 3 basic particle sizes which create three basic soil types: sand, silt, and clay. Investigate the properties of the three different types of soil by observing grain size, shape, hardness, color, chemical composition, pore space, aeration,…

Lesson Plan
Grade: 3rd-5th
In this activity, students learn how engineers use solar energy to heat buildings by investigating the thermal storage properties of some common materials: sand, salt, water and shredded paper. Students then evaluate the usefulness of each material as a thermal storage material to be used as the thermal mass in a passive solar building.Engineering Connection
Engineers design technologies that can turn sunlight into electricity to power households and businesses. For example,…

NGSS Performance Expectations:
Solar power is hot these days. Gleaming, black solar panels soak up rays on more and more rooftops of homes and businesses providing a clean, alternative source of heat and electricity. You might guess that different times of the day yield different levels of solar power. But just how much does the sun's position in the sky affect the power that solar cells and panels can generate? That's the question this project is all about.

Lesson Plan
Grade: 4th-8th
Would it be possible to power everything in your classroom using clean, renewable solar power? Inspired by
Global Problem Solvers: The Series,
in this lesson plan, your students will research and design a solar power system for a mobile classroom that can be used after natural disasters or in remote areas without permanent schools.
This lesson is one of three independent lesson plans inspired by Global Problem Solvers: The Series. You can read more about the series and the lesson plans…
