Second Grade, Energy & Power Projects, Lessons, Activities (8 results)

Whether you are working, studying, or being entertained, much of our daily routines rely on being plugged-in. You probably don't spend a lot of time thinking about where all that power comes from, but someone has to! Figuring out the best ways to produce energy is a big job that is growing along with the world's population. Energy production is a complex topic with debates about whether to invest in fossil fuels or clean renewable energies like solar, wind, water, and geothermal. Take a first-hand look at some of the problems and challenges scientists and engineers are tackling as they look at making and storing energy.

Have you ever cooked something outside, like for a BBQ or while camping? It can be a lot of fun to be outdoors and enjoy eating the fruits — or burgers — of your cooking labors. Did you know that you can directly use solar power to cook food? This can be done using a solar oven, which is a low-cost, ecologically-friendly technology that seems to have everything going for it. In this science activity, you will build your very own simple solar oven out of a pizza box to gather the… Read more
A Battery That Makes Cents
Science Fair Project Idea
Scientific Method
Batteries are expensive, but you can make one for exactly 24 cents! In this experiment, you will make your own voltaic pile using pennies and nickels. How many coins in the pile will make the most electricity? Read more

Have you ever had a sunburn? If so, you know how powerful the Sun's heat can be! Did you know that this heat can also be turned into electrical energy? You may have heard about solar cells, but what about a solar updraft tower? This very simple structure uses the sun to heat up air, which then powers a turbine within a large tower. In this activity, you will build one of these towers yourself. Do you think you can make a propeller spin with just hot air? Read more
Use the Sun's Energy to Heat Your Own Water
Science Fair Project Idea
Scientific Method
Isn't it nice to take a nice, hot shower or bath after a long day of playing outside? But have you really thought about how the hot water in your shower or bath gets hot? Sure, the water heater in your house gets it hot, but what makes the water heater work? Water heaters are powered by natural gas or electricity. But are there any other ways to heat water? What about using the Sun? In this science fair project, you'll give it a try by capturing energy from the Sun to heat water. Read more

How Many Cranks Does It Take to Power a Hand-Cranked Radio?
Science Fair Project Idea
Scientific Method
If you lose power, you can probably still access the internet and read the news with a cell phone. But what if the power goes out for so long that your phone battery dies, or if cellular service also goes down? How would you get news from the outside world? In emergencies, you can use a hand-crank radio, which is powered by manually turning a crank. But just how much power do you get when you turn the crank? How long will the radio stay on before you need to charge it again? Try this project to… Read more
Spinning Your Wheels: Pinwheel Sensitivity
Science Fair Project Idea
Scientific Method
So you've just heard the "Happy Birthday" song and now it's time to blow out the candles. If you are sitting far away from the candles, you know you'll have to blow harder to get them all out than if you were sitting closer. In this science fair project, you'll blow on different kinds of pinwheels with a blow-dryer and see how far away you can get before they stop spinning. This will give you clues about how sensitive the pinwheels are to wind, and why. So come spin your wheels and get… Read more
Want to Warm Up or Cool Down? Go Underground!
Science Fair Project Idea
Scientific Method
Have you ever been so cold sitting in your house in the winter that you feel like icicles could grow off your nose, and your feet could turn into blocks of ice? Or have you ever been so hot in your house in the summer that sweat just drips off you? Making yourself comfortable can mean turning on the heater or the air conditioner, but that costs money. Being cozy or cool does not have to cost a lot of money if you use a geothermal heat pump. In this project, you will build a model geothermal… Read more
