Students visit different departments at a local hospital to see how machines help peoples such as the CAT scan machine. They build a model of such a machine that shows how patients are moved in and out of the machine.

Learners investigate the characteristics of simple machines. For this simple machine lesson, students investigate work as a product of applying constant force. They answer questions about what happens on Earth and what may have happened...

Students apply the mechanical advantages and problem-solving capabilities of six types of simple machines (wedge, wheel and axle, lever, inclined plane, screw, pulley) as they discuss modern structures in the spirit of the engineers and...

Students explore about triangles and the simple machines that are made from those triangles. They are able to identify the kinds of triangles in the machines, tell how the triangular shapes make the machines function, and build a simple...

Third graders examine simple machines. In this simple machines lesson, 3rd graders observe simple machines at work in a video, then experiment with creating their own simple machines to move objects.  

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 technology by completing a worksheet in class. In this common machinery instructional activity, students define the different designs that make simple machines work such as wheels, pulleys and gears. Students utilize...

Students explore optical illusions. Using Legos, they construct and motorize a machine that has an axle that's geared up and geared down, complete a worksheet, and answer discussion questions.

Students experiment with common objects such as spools, string and soap to determine how pulleys make it easier to move large objects. They look at the difference between fixed and movable pulleys. They examine the many uses engineers...

Students identify, compare and contrast simple machines and their functions. They work together in groups to complete experiments using the simple machines. They write in their journals to reflect on the lesson.

Learners research one of the simple machines listed in the lesson and review several simple machine websites to complete their research. Students use software and a watch a video to learn more about machines. Learners create a poster...

Students participate in an online computation game. In this computation lesson, students practice simple computations and use an internet site to review addition and subtraction facts.

Third graders study machines. They watch a video about and identify and chart machines they find at home and at school. They design and build simple and compound machines, create an advertisement for them and attempt to sell them at the...

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.

Students determine how engineers decide on choices for final designs and sites for construction. They look at a surveyor's report while they evaluate sites where a pyramid could be build. They consider the distance the pyramid would be...

Youngsters learn about simple machines that could be used on a farm.  They learn about agricluture, listen to a farmer speak, compare and contrast different farm machines, and then design their own. Note that although the publisher...

Students create pattern books. In this math patterns lesson, students create various patterns using manipulatives. Students take digital photographs of the patterns and create books.

Students explore magnification. In this scientific observation skills lesson, students observe sea life items and draw pictures of what they observe. Students predict which lens will have the strongest magnification when given three...

Students create their own model of a nail clipper. They practice using engineering design and model building. They also identify different kinds of small levers.

Learners determine what the pulse is before examining how to measure the heart rate in different situations. They build a simple device that measures the heart rate, take heart rates, and record them on a worksheet. They discuss how...

Third graders measure the heat created at each center.

Students read The Gadget War by Betsy Duffey. They complete a variety of cross-curricular activities surrounding inventors and inventions. Included are reading, art, math, science, writing, social studies, and library connections.

Students work together to examine inclined planes. They create a plan to raise rocks to build pyramids. They discover the changes that occur when the angle is increased or decreased.

Students explore energy by participating in a science lab in class. For this energy form lesson, students define the different types of energy such as light, mechanical and sound while examining energy measuring tools in class. Students...
