Safety Producing pulp from plant material requires that the plants be boiled in a caustic soda solution. Adult supervision is required, and proper precautions must be observed for handling the strong base.
  • Wear protective clothing and eyewear.
  • Use adequate ventilation.
  • Always add the soda ash (a strong base) to water, not water to soda ash.
  • Use stainless steel or enamel cooking vessel, not aluminum.

Gelatin! It's hard to think of another food that is used as frequently on the dinner table as off. You can find it in all sorts of sweet foods, from ice cream, yogurt, and gummy bears, to marshmallows and yellow colorings for sodas. Off the table, it shows up in glues, photographic paper, playing cards, crepe paper, medicine capsules, hair gels, and professional lighting equipment. From the kitchen to the theater—what a range of uses! In this cooking and food science fair project, you'll… Read more

Time Required Average (6-10 days)
Prerequisites You should have the patience and dexterity to coil several layers of wire neatly (or find someone who can help you). You will also need to hook up a basic circuit. Understanding electric circuits is not a prerequisite for this science project, though it will enable a deeper understanding of the electric generator.
Material Availability A kit containing all the specialty items needed for this project is available from the [# Link Name="Elec_p051.6" Value="HtmlAnchor" #].
Cost Low ($20 - $50)
Safety Neodymium magnets are very strong. Follow the safety guidelines in the Procedure for working with these magnets.
Science Fair Project Idea
The electricity you use to power everyday devices is generated by electrical generators. These fascinating and powerful machines rely on magnets to function. Though they might seem extremely complicated, once you finish this science project, you will understand how, why, and when they generate electricity. You will build your own generator, make small changes in how exactly the magnets are placed, and test when moving magnets generate electricity. Read more

Science Fair Project Idea
If you have ever prepared a cup of coffee or tea with sugar, you have probably seen that the grains of sugar quickly dissolve and completely disappear in hot water. But sugar is not the only type of solid that can readily dissolve in a liquid. In fact, there are some types of rocks that can be dissolved by common liquids. It might be hard to imagine large, hard rocks being eaten away by some ordinary fluids, right? But it actually happens all the time! In this geology science project, you will… Read more

Science Fair Project Idea
What do humans need to survive? We need food, water, and warm shelter. We all need a warm place to live, particularly when it's chilly outside. How do many of us warm our houses or apartments? We depend on fossil fuels to supply gas and electricity to our heaters. But burning fossil fuels to create energy is harmful to the environment. What if there was a way to warm our homes without burning fossil fuels and it was free? In this science fair project, you will build a solar air heater and see… Read more

Have you ever felt really frustrated? Maybe you were playing a video game and could not easily figure out a particularly challenging puzzle. Or maybe there was something you really wanted but you could not have it for some reason. However it has happened, what do you do when you get frustrated? What about other people — what kind of behaviors have you seen others display when they get frustrated? Do they cry, jump up and down screaming, just give up, or become aggressive? In this human… Read more
