Students define the words "reversible" and "irreversible." They complete a worksheet that shows a number of changes. Students must decide which are reversible and which are irreversible.

Learners identify healthy foods. In this nutrition lesson plan, students review the five food groups and categorize healthy and unhealthy foods on a chart. Learners develop their own menus.

Students learn to understand the role of both skeletons and exoskeletons. For this lesson on exoskeletons, students locate and label bones on diagram of a human skeleton, and observe and discuss bones of chicken and fish. Students then...

Students participate in a culminating activity for a unit on Energy and Simple Machines. They are challenged to incorporate simple machines in to a complex mechanical system. While designing and testing their machine they will also...

Students know that humans and some other animals have bony skeletons inside their body. They know that other animals have skeletons on the outside of their bodies. They explain the role of both kinds of skeletons.

Students explore animal diets and teeth. In this animal science lesson, students view photos of animals and their teeth. Students identify the type of diet the animal has based on the teeth. Students are introduced to the terms...

Aspiring aeronautical engineers demonstrate different forces as they construct and test paper airplanes. This lesson plan links you to a website that models the most effective paper airplane design, an animation describing the forces...

Students study the physics used to design today's roller coasters.  In this engineering lesson students complete several activities including designing their own roller coaster. 

Students describe how to recognize a force, define balanced and net forces, state Newton's first law of motion, explain why friction works, state Newton's second Law of Motion, and explain why the direction of force is important.

In this online interactive English vocabulary skills worksheet, students answer 6 multiple choice questions which require them to read a sentence and determine the meaning of words or phrases in the sentences....

Fourth graders study everyday examples of simple machines. They examine how the combination of a wheel and axle works more efficiently than either in isolation. In a demonstration lesson, they see how a spring scale shows a force pulling...

Sixth graders use small electronic devices known as thermistors to measure the temperature beneath an object such as a coffee cup as it slides across a surface. By choosing different surfaces, 6th graders can compare in a quantitative...

Fourth graders examine the physics behind and uses for inclined planes, screws, and wedges. They determine examples of how these simple machines are used in daily life. Working in three small groups, they move from station to station...

Students explore the ins and outs of simple machines. They discover the various roles of simple machines, who uses them, where they can be found and how they actually work. Students create a compound machine using simple machines.

In this Sir Isaac Newton instructional activity, learners use links provided to complete answer to questions related to Newton and his "laws." Worksheet included extended thinking activities.

Students simulate block and tackles to lift heavy objects. They lift cargo by hand with the whip and the two-fold purchase to simujlate what crew members do aboard ships. They measure the effort and distance pulled for a gun tackle, luff...

The principles behind pulleys, levers, and simple machines are the focus of a science lesson. In it, learners take part in a whole-class activity. There are two groups of pupils who each must lift objects with fixed pulleys and multiple...

Students design an appropriate and usable storyboard and then create a claymation video. They take digital photographs frame by frame, then assemble the stop-motion movie using video software.

Students design a roller coaster and demonstrate their knowledge of Potential and Kinetic Energy. They determine the average velocity a given marble travels on their roller coaster and apply their knowledge of various measurement systems...

Were it not for Sir Newton, our understanding of physics and matters of the world would be drastically different. Present your class with detailed information of Newton's Second Law as they explore the concepts of mass and acceleration....

Students use materials found at a resource table to design simple devices that will house instruments to take water samples from a tub of water. They design 3 instruments, each varying in density so that one will float, one will hover...

Young scholars explore the properties of magnets by designing a device that can move as far as possible using only magnets to move it, and design a machine that will stay in motion for the greatest period of time.

Learners, in teams, use given materials and their knowledge of Newton's First Law to create a device that will remove a sticky ping pong ball from a 16-oz. cup (which represents ketchup stuck in a bottle.)

Young biologists identify parts of the body, sort humans from other animals, and list the difference they see. Learners are split up into groups of three, and each group must find pictures in magazines of humans and other animals. They...
