Students will discover the scientific basis for the use of inclined planes. They will explore, using a spring scale, a bag of rocks and an inclined plane, how dragging objects up a slope is easier than lifting them straight up into the air. Also, students are introduced to the scientific method and basic principles of experimentation. Finally, students design their own use for an inclined plane.
Subject:
Mathematics and Statistics, Science and Technology
Students are introduced to the concept of simple tools and how they can make difficult or impossible tasks easier. They begin by investigating the properties of inclined planes and how implementing them can reduce the force necessary to lift objects off the ground.
Subject:
Mathematics and Statistics, Science and Technology
Students explore building a pyramid, learning about the simple machine called an inclined plane. They also learn about another simple machine, the screw, and how it is used as a lifting or fastening device. During a hands-on activity, students see how the angle of inclination and pull force can make it easier (or harder) to pull an object up an inclined plane.
Subject:
Mathematics and Statistics, Science and Technology
Students use inclined planes as they recreate the difficult task of raising a monolith of rock to build a pyramid. They compare the push and pull of different-sized blocks up an inclined plane, determine the angle of inclination, and learn the changes that happen when the angle is increased or decreased.
