Students investigate how to make a lever. In this construction lesson plan, students explore how to construct a lever using dog and tail templates, cardboard, and fasteners. Students construct their simple machine in order to learn about...

The principles of levers and simple machines are presented here. An easy-to-make lever is constructed by each group of scientists, and they use it to explore how this simple machine makes heavy things so much easier to lift and move. A...

Class members are challenged to design a device that will move a circus elephant into a train car. Groups brainstorm ideas that use simple machines to load the elephant. They then choose one of their ideas, sketch a plan, and present it...

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...

Everything in moderation, especially candy. Scholars design and build a dispenser for candy. But, they can't get too carried away—only three or four pieces of candy can come out of the dispenser at one time.

Students examine the lever. In this simple machines lesson plan, students construct a lever by using two pencils, three pennies, and a ruler. Students explore the uses of a lever.

Fifth graders explore the concept of pulleys and levers. They read and discuss text from the book "It's Science! Machines We Use," and in small groups construct a simple lever and pulley using a Lego Dacta set.

Students construct a catapult that shoots a cotton ball at least two meters using Legos, rubber bands, and plastic spoons. They discuss how the catapult works, and identify any problems they had with their experiment.

Fifth graders read information about levers. They complete worksheets to summarize their learning. This activity relies heavily on the Silver Burdett Ginn text, Science Discovery Works, Energy, Work, and Machines. The activity will not...

Students create a simple machine that includes a cart and lever system that could have been used to build the ancient pyramids. In this simple machine lesson, students learn about the wheel and the axle as simple machines that help...

What's the best way to use a simple machine to solve a real-world problem? Scholars construct their own simple and complex machines to explore the concepts of work and force. They discuss examples of simple machines they have found in...

Students recognize and identify common objects that can be used as a lever. In this simple machines lesson, students experiment with materials to design and construct a machine that uses a lever. Students also design and build a catapult.

Examples and practice questions will help real-life understanding of the Principle of Moments concept. These great slides define the types of levers and pivots, and then give examples of the typical seesaw situations that help the...

Ready, aim, fire! Launch to a new level of understanding as scholars build and test their own catapults. Learners explore lever design and how adjusting the fulcrum changes the outcome. 

Class members work in pairs to build a catapult to launch a grape a given distance. The catapult project, a compound machine, reinforces pupils' understanding of simple machines.

Students use common materials to build a car. In this car building mechanical engineering lesson plan, students build a car using a milk cartoon and plastic wheels. They discuss what mechanical engineers do and what makes a car run.

Get things moving with this elementary science unit on simple machines. Through a series of nine lessons including teacher demonstrations, hands-on activities, and science experiments, young scientists learn about forces, motion,...

Using a teacher-built wind tunnel constructed from a paper concrete tube form, a fan, and a balance, individuals determine the amount of drag their rocket design will experience in flight. Pupils make modifications to increase the...

Students use a simple machine (a lever) to launch a plastic frog. students determine who is able to make their frog "jump" the farthest and graph the results.

Students explore the drawings of Rube Goldberg to design and construct a simple machine. They discuss simple machines, and using various materials and toy parts, design and construct a "Rube Goldberg" style machine to ring a bell.

Students use everyday materials (milk cartons, water bottles, pencils, straws, candy) to build a small-scale transportation device that incorporates the wheel and axle and the lever. They race their carts/trucks, measure distance, time...

Seventh graders complete a challenge to create a catapult that projects a marble or other projectile at least one meter. While experimenting they apply the Four Question Strategy to answer the question, " How can I make one modification...

After a brief lecture on levers, torque, projectiles, and the five-step engineering design cycle, young physical science learners or engineers build catapults out of craft sticks. This is an open-ended exploration of what works and what...

Fifth graders create a Power Point presentation to relate to their study of simple machines. They create a title page, a page introducing six simple machines, slides explaining real world use to each simple machine and import pictures...
