You might have read about the negative impacts modern human civilization has had on the environment, like pollution, deforestation, and extinction of animal species. How can we use modern technology to help protect the environment? In this project-based lesson students will design an electronic circuit that can measure something in the environment like water quality and light pollution, and develop a plan for how their circuits could be used to solve a real-world problem.

NGSS Performance Expectations:

HS-ESS3-4. Evaluate or refine a technological solution that reduces impacts of human activities on natural systems.

Purification Strategies

Science Fair Project Idea

Scientific Method

In order to study individual biochemical compounds like proteins, DNA, or RNA, biochemists need to know how to purify these components from a complex mixture. This is especially important for biotechnology and pharmaceutical industries, which sell purified biochemicals as reagents or drugs to consumers. Do an experiment to purify DNA, RNA, or protein from a complex mixture (for purifying DNA, see the Science Buddies project Extracting Onion DNA). The source of the material can be a cell… Read more

Push, Pull and Weight

Lesson Plan Grade: Kindergarten

Experimenting with balls is fun! In this hands-on lesson, you and your students will make them collide and study how balls can push each-other and people too! While exploring, students will also feel how pushing a light ball is different from pushing a heavier ball. Weight is important. This lesson fits well together with a lesson where students push balls to discover how people use pushes and pulls to change motion. Read more

NGSS Performance Expectations:

K-PS2-1. Plan and conduct an investigation to compare the effects of different strengths or different directions of pushes and pulls on the motion of an object.

Did you know we use our side vision for many daily activities, like riding a bike, reading or playing basketball? Few people realize they are even using it. Our survival once depended on the quick response of our peripheral vision. A detailed picture, created by our central vision, is only useful in situations where time allows us to focus on the details. But our side vision can help us avoid dangers quickly. In this activity, you will find out how specialized our peripheral, or side vision, is. Read more

Recycling PLA Plastic using Green Chemistry

Lesson Plan Grade: 9th-12th

Educational Goal To understand: How polylactic acid (PLA) plastic is an example of green chemistry technology particularly pollution prevention and designing safer chemicals Student Objectives Students will: Learn about renewable "corn" plastic is made from polylactic acid Recycle the polylactic acid cup into a new product: a cleaning solution Conduct a saponification reaction Analyze PLA against the 12 principles of green chemistry (Optional) Verify the contents of their… Read more

Red Eye

Science Fair Project Idea

Scientific Method

How does the angle between the lens, the subject's eye, and the flash effect the appearance of red eye? How does the subject's eye color effect red eye? Read more

Relationships Between Variables: Using Correlation and Linear Regression

Science Fair Project Idea

Scientific Method

Here's a project that combines sports and math. You'll learn how to use correlation analysis to choose the best team batting statistic for predicting run-scoring ability (Albert, 2003). You'll also learn how to use a spreadsheet to measure correlations between two variables. The project description Which Team Batting Statistic Predicts Run Production Best? provides the details.

Remodeling and Energy Efficiency

Science Fair Project Idea

Scientific Method

Has your house (or one of your friend's houses) been remodeled recently? Were any improvements made for energy efficiency (solar systems, better insulation, passive solar heating, better lighting)? Compare your family's energy costs for a similar time period before and after the remodeling (remember that energy usage often varies seasonally). Monthly bills often have a bar graph showing energy usage for the previous 12 months. You may also be able to get information on past energy usage… Read more

Renewable Energy Resources

Science Fair Project Idea

Scientific Method

Coal, gas, and oil are energy resources that are not renewable, meaning that once we use up the world's supply of these natural resources there will not be any left. There is a lot of debate about how long these resources will last. One way to ensure that we will not find ourselves in an energy crisis is to develop energy resources that are renewable. Renewable energy is a resource that cannot be used up. Investigate the many uses of renewable energy: solar energy, wind energy,… Read more

Respiration and Gills: What Factors Affect Respiration in an Aquatic Environment?

Science Fair Project Idea

Scientific Method

During metabolism, organisms experience physical and chemical changes. All animals need some way to exchange chemical waste generated during metabolism for fresh nutrients. One way that these metabolic chemicals are exchanged is during respiration, the process by which used carbon dioxide gas is exchanged with fresh oxygen and circulated throughout the body. How do organisms living underwater respirate? They use gills, which filter oxygen from the water and pass the oxygen into the… Read more
