Twisting and turning through the sky, roller coasters are popular attractions at amusement parks around the world, but how exactly do they work? Explore the physics behind these thrilling rides with an engineering design activity....

How do we interact with Earth? Scholars learn about the sun, Earth, moon, forces, gravity, and heat sources by reading a text and performing hands-on demonstrations. They also differentiate between living and non-living things using...

Planning an elementary science unit has never been simpler! These twelve lessons guide young scientists through an exploration of simple machines and their many uses in the real world before asking them to apply their learning...

The choice is simple: create a PowerPoint presentation, write a book, or invent a compound machine. Whichever project your young scientists choose, they will be engaged in creatively demonstrating their knowledge of simple...

For this comprehension exercise, kids read a physical science article about forces that can move an object, and then answer a series of questions about the passage.

Convert energy within a can. Learners build a can that suspends a weight inside the can via a rubber band. The pupils roll the can away from them as the rubber band wraps around itself. The force of the band unwinding brings the can back...

If only we could harness the energy of fifth graders, our energy problems would be over! The class discusses where different forms of energy come from and how we use them. They complete a chart of the activities that they do daily...

Three, two, one, blast off to a better understanding of force and motion with this exciting science lesson! Beginning with a discussion about rockets and gravity, young scientists go on to complete a series of worksheets about net...

Students conduct a variety of experiments related to solar energy, heating, cooling, gravity, physical insulation and wind. They consider how the experiments relate to energy and the consumption of energy and then participate in a class...

Make your work as a teacher a little easier with a physical science project on simple machines. After introducing young scientists to these devices and identifying their different uses around the school, this project engages...

Using footballs, basketballs, tennis balls, and more, learners conduct experiments to illustrate Newton's Laws of Motion.  The experiments are conducted outside, and require them to throw, kick, and hit a variety of balls. Your...

Create egg drop soup. Teachers first set up eggs that are held up above cups of water with a piece of cardboard and cardboard tubes. Learners try to determine a way to get the eggs to drop into the cups. Using a broom, the instructor...

Students investigate the effect that weight has on rocket flight. They construct a variety of straw-launched rockets that have different weights, observe what happens when the weight of a rocket is altered by reducing its physical size...

Six simple images pull your class into magnets. Most of the pictures show magnetic fields as revealed by iron filings. Concepts are explained in print along the bottom of each slide and include magnetic force, force fields, poles,...

Stuents explore wheels and axles and how they maka machine move. After a teacher demonstration, students construct a wheel and axle. Students explore the circumference of the wheel. They compare the wheel sizes, speed, distance, and load...

Young scholars describe the science of physics. In this Physics activity, students observe examples of physics within their classroom. Young scholars create a definition for physics.

Young scholars investigate the properties of force and gravity and their effects on everyday life. In groups, they test various balls by bouncing them on different surfaces and observe the properties. In another activity, they test...

Learners study and identify different types of simple machines and how they work. They design a simple machine.

In this 3rd grade science worksheet, 3rd graders complete a total of 25 multiple choice questions related to grade 3 concepts. An answer key is given.
