Science Fair Project Idea

Scientific Method

Is there a public park, playground, or beach near you that suffers from a litter problem? Here is a way that you can do something about it! First, get a measure of the size of the problem by conducting a litter survey. Select a fraction of the area to survey at regular intervals (e.g., every two or three days, or maybe once a week). The area should be large enough so that you can get a representative sample of litter, but not so large that you can't clean it up. Each time you conduct your… Read more

Flight Simulators: From Flaps to Flying

Science Fair Project Idea

Scientific Method

Did you know that commercial airline pilots use high-tech flight simulators to learn how to fly big jumbo jets? Before they ever step behind the controls of a real jet they've already logged thousands of virtual air miles. It might not qualify you to fly a real jumbo jet, but you, too, can learn the logistics of aviation by experimenting with the types of flight simulators sold at computer game retailers. Use a flight simulator to investigate the relationship between flap settings and the stall… Read more

Focusing Your Flash for 'Freezing' Motion

Science Fair Project Idea

Scientific Method

Here's an interesting flash photography project. With an inexpensive Fresnel lens, you can concentrate the light from your flash. You'll be able to shoot with a smaller aperture and a shorter flash duration. This will give you greater depth of focus and will allow you to 'freeze' motion at higher speeds. The trade-off is that the light will be concentrated toward the center of the frame. This project shows you how you can investigate that trade-off and find out how you can best use your flash… Read more

When your students think of robots, they probably think of materials like metal or plastic—but what about paper? In this lesson plan, your students will learn to make robotic parts from readily available classroom materials. Optionally, they can apply the engineering design process to improve the design or come up with their own designs. Read more

"Fresh Food In Garbage Can to Illustrate Waste" by SpeedKingz/Shutterstock.com Have you ever thrown away food after a meal? Have you ever thrown away a whole piece of food? What are some of the reasons you threw away that food? During this Food Waste Audit, students will explore their own impact on our food system. Students will brainstorm solutions to reduce their food waste and be challenged to try out their solution! Read more

"Nuclear Power Plant Cattenom" © 2005 Stefan Kühn In these two activities, students will explore two consequences of burning fossil fuels: air pollution and the greenhouse effect. For a comprehensive unit on fossil fuels, this lesson works especially well as an extension to Fossil Fuels: Chocolate Chip Mining. Read more

NGSS Performance Expectations:

4-ESS3-1. Obtain and combine information to describe that energy and fuels are derived from natural resources and that their uses affect the environment
MS-ESS3-4. Construct an argument supported by evidence for how increases in human population and per-capita consumption of natural resources impact Earth's systems.

Frequency Histograms

Science Fair Project Idea

Scientific Method

Can you remember what the weather was like last week? Last year? Here's a project that looks at what the weather was like for over a hundred years. You'll use historical climate data to look at moisture conditions in regions across the continental U.S. You'll use a spreadsheet program to calculate the frequency of different moisture conditions for each region and make graphs for comparison. Which part of the country has the most frequent droughts? The most frequent periods of prolonged… Read more

Frequency of Outcomes in a Small Number of Trials

Science Fair Project Idea

Scientific Method

People often draw conclusions from a small number of observations, and use those conclusions to evaluate the likelihood that an event will take place. But how easy is it to draw the wrong conclusion based on those observations? Will your predictions be accurate if an experiment is only performed a few times? The objective of this project is to determine what happens when a test with two equally-likely outcomes is performed only a small number of times. You can test this by flipping a coin. A… Read more

From Farms to Phytoplankton

Lesson Plan Grade: 6th-11th

"Morganza Spillway" © 2011 NASA Earth Observatory Can we use a model to predict the impacts of nutrient pollutants on an aquatic ecosystem? In this activity, students participate in a kinesthetic simulation to illustrate how nutrient pollution from agricultural runoff can lead to a dead zone at the mouth of a drainage basin. Read more

From Your John to the School Lawn: Is Recycled Water Really Safe?

Science Fair Project Idea

Scientific Method

Reclaimed (treated) wastewater can be used for many purposes, including landscape watering and freeing up valuable fresh water for other purposes (like drinking water). It's a great way to conserve water, but is it really safe? This science fair project is designed to find out. Read more
