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. 

Drop a perfect project into your lesson plans. Groups use different building materials to create models of parachutes for food drops. After testing out their prototypes, they make improvements to their designs.

Students discover how air pressure effects flight.  In this physics lesson, students create two types of airplane wings so they can observe the way air pressure creates lift.  Students utilize a printout to create the airplane...

Third graders view a demonstration of a teeter totter as a basis for assessing pre-knowledge of a lever. They create a KwL chart. Students work in small groups to conduct a variety of experiments. The first requires students to tie books...

Young scholars examine cloud types. In this cloud lesson, students identify cloud types, observe clouds and collect data, and analyze data to identify the most common cloud they observe overhead during the course of a month.

High schoolers compare different types of pressure sensitive adhesive tapes. They fevelop and carry out tests for variables affecting the force needed to peel tape off a surface. Students analyze the time needed to peel the tape with...

Students investigate how engineers use different types of bridges for different places. In small groups they design and construct bridges for three different scenarios, and answer a series of investigating questions applied to the...

Students discover how weather conditions can give rise to severe storms and tornadoes. They study the different types of severe weather, how they can track conditions in their own neighborhood, and how to prepare for the worst.

Ninth graders experiment with Isaac Newton's Third Law of Motion. In this Third Law of Motion lesson, 9th graders develop an experiment that shows their understanding of this theorem. They work in small groups to read an article at a...

Students build a model of a bridge and test the amount of weight it support. They identify different types of bridges: suspension, arch, girder, truss, cantilever, cable-stayed and moveable.

Learners create geologic maps of the Gettysburg battlefield. In this geologic skills lesson, students consider the variations of Earth's surfaces and explore strategies employed by the North and South in the Battle of Gettysburg to...

Radioactive decay, pH, properties of elements, organic compounds, and stoichiometry are all touched upon through this practice chemistry exam. It always helps learners to take a practice test in preparation for the actual exam. This...

Provide a Hooke for a lesson on elasticity with an activity that has groups investigate a set of springs. They use a set procedure to collect data to calculate the spring constant for each spring using Hooke's Law. The groups...

The water cycle is one of earth's most easily observable processes, but demonstrating each step within classroom walls can be a challenge. Through a series of videos and quick demonstrations, cover each aspect of the hydrologic cycle in...

Three Dog Night isn't just the name of a band; it is also the way an Australian tribe, who used dogs to stay warm, would describe the temperature on a cool evening. After reading about many different ways of measuring temperature, the...

Engage your class by showing them how silly putty and human tissues are alike. Pupils learn more about tissue mechanics by reflecting upon their experiences with silly putty. The lesson covers   collagen, elastin, and...

In this waves instructional activity, students read about the different types of waves and how the speed of waves is calculated. Then students complete 5 matching, 8 fill in the blank, and 9 short answer questions.

Students examine different types of extreme weather and how to prepare for them. In this weather instructional activity students explore different types of extreme weather and create disaster preparation posters for different types...

Young scholars explore different types of simple machines and research the concepts of force, effort, and work. They conduct Internet research and complete a worksheet about examples of simple machines used in everyday life. Students...

Students determine the identity of the three classes of levers while explaining how each works. They wait a video clip that shows uses for different types of levers and work as a class to write a KWL chart. Finally, they make a model fo...

Young scholars explore the layers of the Earth using a Snicker's bar. In this science lesson, students identify the parts of the Snicker's bar and identify which layer of the Earth the parts of the candy bar would represent. Young...

A professional-quality PowerPoint, which includes links to footage of actual landslides in action, opens this moving lesson. Viewers learn what conditions lead to erosion and land giving way. They simulate landslides with a variety of...

Back to the basics (of surface tension). The first installment of a nine-part series teaches young scholars about the basics of surface tension and how it relates to water droplets. They also learn how this concept allows for the...

Middle schoolers explore erosion when there are multiple types of sediments. They view a soil separation demonstration jar before and after agitation to determine how and why the layers settled. In addition, they conduct experiments with...
