What time of day tends to be best for charging a solar cell?.

How would you use solar energy most effectively in your home or school?.How could you use a solar cell to recharge a battery? (YouвЂ™ll need to use a diode and set up a circuit.) How does a solar cell compare to a battery with the same voltage?.

Compare the effectiveness of different types of insulation.

How does the efficiency of an incandescent bulb compare to a fluorescent? What about LED? How much heat energy do they produce?.

Explore centripetal force by designing and building a mini roller coaster and demonstrating the physics behind it.

Create a similar experiment with a bow and arrow.

Experiment with how much more energy is needed to catapult a heavier object the same distance as a lighter object.

What types of metal conduct heat the fastest? Do some conduct heat more evenly than others? What types of materials are good insulators?.

What type of pulley provides the highest mechanical advantage for a particular job?.

What are the resulting velocities after a moving and unmoving object collide? What about two moving objects in same or different directions?

Use toy cars or a dynamic cart to test what impact increased mass has on velocity.

Older kids can use a spring scale to measure the force of friction.

What type of flooring (carpet, wood, tile, linoleum, etc.) creates the most or the least friction? (Younger kids might test this by rolling a ball or toy truck over different surfaces.

How do different brands of plastic wrap compare when stretched with equal force? How do different brands of duct or clear tape compare in strength and stickiness? Can you identify what factors cause one to perform better than another?.

Create an experiment showing how well (or poorly) different structures or materials withstand pressure.

Design an experiment using a rocket car powered by a balloon.

Experiment with thrust and aerodynamic design while launching a rocket.

What are the best shapes for paper airplanes? The best material for propellers?.

Explore maglev technology (magnetic levitation).

How could this principle be applied to real-world technology, like braking systems on roller coasters?

Experiment with how magnetic and electric fields can make a magnet fall in slow motion.

What types of liquid can conduct electricity? Can electricity be used to split water into hydrogen and oxygen?.

What indoor and outdoor materials (such as metal poles, a window, etc.) make the best antennas for your radio? Under what conditions, such as temperature, cloud cover, and humidity, does your radio pick up the clearest signals?

Can you use a magnet to find traces of iron in food, dollar bills, and other household materials?.

How well does a carbon rod instead of a metal rod work as a positive electrode?

Make a voltaic cell and research which household electrolytes are most effective for producing electricity.

Make electromagnets with different strengths compare their magnetic fields using iron filings to find what effect they have on a compass needle and how strong their attraction is (e.g., which one can pick up the most paperclips?).

How can you create it? How you can reduce it? What substances or objects are the best conductors of static electricity? Do conditions like humidity and temperature increase or decrease static electricity? вЂ“ Browse our Science Fair Supplies category for more project ideas.

вЂ“ For tips on performing your experiment and presenting your project, see our free science fair guide. ThatвЂ™s why physics science fair projects make good impressions on judges. Most branches of engineering are applied physics. Physics is the basis for chemistry (the interaction of atoms and molecules).
