Earthquakes

Science Fair Project Idea

Scientific Method

Visit the USGS Earthquake Hazards Program to find out about global patterns of earthquake incidents (USGS, 2006). Can mapping earthquakes help identify fault lines? They also have a list of science fair project ideas. Another great resource for earthquake-oriented science fair projects is by Jeffery Barker (Barker, 1994). Build a model to study the forces of an earthquake using sandpaper-covered blocks. What are the forces involved? How are stress and friction in balance along a fault line?… Read more

© 2009 California Academy of Sciences How can we determine the locations of tectonic plate boundaries? How can we use seismic waves to pinpoint the epicenter of an earthquake? In this activity, students will explore these and other questions using seismic data and triangulation. Read more

Earthworm Castings — The Ideal Proportion in Soil for Young Garden Plants

Science Fair Project Idea

Scientific Method

Everybody knows that worms are good for the soil, but not everybody knows why. Here's a project that investigates just one of the ways earthworms improve the earth. Would earthworm castings (or earthworm manure) help your plants prosper and flourish? If so, how much should you use? Read more

Eco-Friendly Squishy Robots

Science Fair Project Idea

Scientific Method

In our introductory VoxCAD project, you were challenged to use the VoxCAD software to design the fastest possible robot using different materials. However, we did not ask you to think about one big thing — efficiency. It is great to design a robot that is very fast, but what if it also consumes a lot of energy? Engineers must consider this when designing robots in the real world — robots that use more energy to move will drain their batteries faster, which can be a problem. This is… Read more

In this lesson, students will do a simple exercise with M&Ms to understand what environmental impact factor (E-factor) is, how it applies to chemical processes, and how waste from chemical reactions can be reduced by applying the principles of green chemistry. Learning Objectives Students will: Understand strategies for reducing waste Perform an exercise which has them practice E-factor Relate the exercise to chemical processes NGSS Alignment MS-PS1-3. Gather and make… Read more

Space exploration poses many challenges. In this lesson, students will explore how flying a helicopter on Mars is different from flying a helicopter on Earth due to the difference in the helicopter's weight on Mars and the thin Martian atmosphere. Students will follow the engineering design process to design and build paper helicopters that might be able to fly on Mars. Before testing their different helicopter designs, students will revisit the concept of gravity, and apply their knowledge to… Read more

NGSS Performance Expectations:

MS-PS2-4. Construct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects.
MS-ETS1-4. Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.

Environmental Monitoring

Lesson Plan Grade: 6th-8th

Does human activity impact the environment? If so, how can we measure our impact on the environment? How can we use these measurements to change our behavior? In this project, your students will explore these questions by designing and building an electronic circuit that can measure environmental parameters like water quality or light pollution. Read more

NGSS Performance Expectations:

MS-ESS3-3. Apply scientific principles to design a method for monitoring and minimizing a human impact on the environment.

Fabulous Fabrics: The Chemistry of "Green" Textiles

Lesson Plan Grade: 6th-8th

Look around and you will see fabrics everywhere, from clothes to upholstery, in a wide range of colors. In this chemistry lab students will dye strips of fabrics to explore how variables like pH and fiber type influence fabric colors. Students will also look at the life cycles of natural and synthetic fibers and apply green chemistry principles to understand how science can help make advances towards a "greener" textile industry. Learning Objectives Students will: Understand that synthetic… Read more

Factors that Affect the Transfer of Force through Saturated Soil

Science Fair Project Idea

Scientific Method

Soil liquefaction is a phenomenon where soil that is saturated with water suddenly loses its strength and behaves like a liquid. This usually occurs due to sudden, large stresses on the soil — for example, from an earthquake. This can be very dangerous for buildings sitting on top of the soil, as they can suddenly sink into the ground! The embedded video explains soil liquefaction in more detail. Is there a way to prevent soil liquefaction? Do you think adding certain materials to… Read more

Feel Free to Sleep at School... If You're a Computer!

Science Fair Project Idea

Scientific Method

Sleeping in class isn't allowed... unless you're a computer! In fact, the Environmental Protection Agency (EPA) suggests that putting your school's computers to sleep when they're not in use might reduce a school's energy bill significantly. In a study done at the North Thurston public schools in Olympia, Washington, EPA officials worked with the district to cut computer energy and costs by approximately $45,000 annually! How? By implementing a variety of power-management strategies for the… Read more
