Explore Interplanetary Spacecraft Maneuvers with FreeFlyer®
Science Fair Project Idea
Scientific Method
If you are interested in space travel and willing to do some coding, this project is for you! It uses FreeFlyer®—powerful software that allows you to simulate space travel—to explore essential mission questions. Space travel is complex. Many factors influence the trajectory of a spacecraft. Simulations like the ones generated by FreeFlyer are powerful, as they allow you to analyze each factor in isolation, and then visualize the effects in various ways. Once you familiarize… Read more
Explore the Effects of pH on Lead Testing.
Science Fair Project Idea
Scientific Method
Lead is a very hazardous element. Even very small amounts can cause health problems, especially in babies and young children. One way to determine if a household item, such as a toy or a piece of jewelry, contains lead is to soak the item in a solution, and then test the solution for lead that might have leached out of the item. The goal of this chemistry science fair project is to determine how varying the pH of the test solution affects its ability to dissolve lead, which is a critical step… Read more
Exploring Our Growing Need for Water
Lesson Plan Grade: 6th-10th
© 2015 California Academy of Sciences In this two-day lesson, students will be introduced to several water sustainability issues, including access to clean freshwater, groundwater depletion, agricultural water use, and water waste. Read more
Expression Cloning
Science Fair Project Idea
Scientific Method
What is expression cloning and how is it used in the biotechnology industry? How are plasmids constructed for use in a bacterial expression system? You can investigate these questions and more using bacterial expression kits meant for high school classes. You will need a laboratory space equipped to grow bacteria and carry out simple molecular biology. A kit with plasmids and bacterial cells to transform are also needed. Here are two possibilities: BioBuilder What a Colorful World Kit … Read more
Extracting Heat Energy from a Compost Pile
Science Fair Project Idea
Scientific Method
Earth, the Sun, wind, and water are all sources of renewable and sustainable energy—and sources you probably already know about. But did you know that you can get energy from such things as banana peels, coffee grounds, and newspaper? In a process called composting, you can transform kitchen and other solid wastes into a product that is beneficial for your garden: homemade fertilizer. As the waste decomposes, it also creates heat. Can this naturally created heat be put to use? In this… Read more
Feeding Fido & Fluffy: Designing an Automatic Pet Feeder
Science Fair Project Idea
Scientific Method
An overnight trip to the beach or a quick two-day vacation can be lots of fun. What do you do to prepare? Pack your clothes, get sunscreen lotion, and borrow a book from the library. But wait! Who is going to feed your dog or cat? It would be irresponsible to let them go hungry. And you can't just leave food out, because it can get stale and start to grow bacteria, which can cause your pet to get sick. Also, it is not a good idea to leave bowls of food out because a pet might overeat, which is… Read more
Foggy Forecasting: What Weather Factors Create Radiation Fog?
Science Fair Project Idea
Scientific Method
The poet Carl Sandburg wrote, "The fog comes on little cat feet..." In this weather science fair project, you'll discover why this beautiful, quiet creeper appears on some days, and not on others. If you are fascinated by fog and weather conditions, this science fair project is for you! Read more
Football: Punting
Science Fair Project Idea
Scientific Method
When the punter is trying to hit the "coffin corner" (within the opposing team's 10-yard line), out of bounds, what is the best angle to kick the ball for correct distance and maximum "hang time?" (For more information on the physics involved, see: Gay, 2004, Chapters 4 and 5.) Read more

Students explore how force, mass, and acceleration are related in this hands-on lesson plan. By experimenting with pushing a box across the table while varying force and mass and measuring the box's acceleration with a mobile phone and a sensor app, students discover Newton's second law of motion for themselves. Read more
NGSS Performance Expectations:
  • HS-PS2-1. Analyze data to support the claim that Newton's second law of motion describes the mathematical relationship among the net force on a macroscopic object, its mass, and its acceleration.
Free Power from the Sun!
Science Fair Project Idea
Scientific Method
Do you like getting something for nothing? Everybody likes getting things for free. How about getting energy and power for free? The Sun sends us free energy every second and all we have to do is collect it. Taking advantage of free energy can reduce our dependence on fossil fuels, which are harmful to our environment. In this science fair project, you will work with a solar panel, which is a collector of free energy, and investigate how varying the angle of the solar panel, and thus the amount… Read more
