Young scholars see that understanding how sound is produced makes it possible for us to manipulate it so we can decrease the number of unpleasant sounds we encounter. They make a drum to explore the concepts of force, pitch and volume.

Students examine electric fields using viewers to discover the direction of positive charges and the location of the field's strength. They experiment with positive, negative, like and opposite charges. Students also describe how...

Students create a model bridge using steel. In this bridges lesson plan, students study John Augustus Roebling and how he created bridges out of steel and the impact it had on society. Then students build their own bridge model.

In this force and motion worksheet, students complete an on-line quiz, clicking on questions and matching answers, scoring 1 point for each correct answer. A printed version is available.

In this force and motion quiz activity, students complete an on-line quiz, clicking on questions and matching answers, scoring 1 point for each correct answer. A printed version is available.

Eighth graders examine the forces that are constantly acting on the Earth. They describe the theory of tectonic plates and demonstrate the two kinds of earthquake waves. They also examine the role of volcanoes in the structure of the...

Pupils use common household and classroom objects to generate static electricity and study its effects. They discuss the video Science Rock CD called Electricity, Electricity. The video explains many things about electricity.

Students apply the scientific method to identify rocks from glacial deposits, hypothesize how they got there and then test their hypothesis. They are given the experience of active, hands-on inquiry.

In this laws of motion quiz learning exercise, students complete an on-line quiz, clicking on questions and matching answers, scoring 1 point for each correct answer. A printed version is available.

Starting off with a definition of motion and some examples, this slide show goes on to describe different categories of movement. Terminology connected to this general physics topic is explained on subsequent slides. It is a good summary...

Stick this resource in the "Use" column. In the second installment of a six-part series, learners use glue sticks to demonstrate forces. Using glue sticks, instructors can demonstrate tension, compression, and torsion.

Students examine how the movements of bones are dependent on the interaction of pairs of muscles. They design and construct a prototype of an artificial limb using a syringe system, and determine whether water or air makes the appendage...

Do you think chromatography paper suffers from separation anxiety? Young chemists make soap, slime, silly putty, and experiment with chromatography in this lesson. The material includes clear instructions for each experiment along with...

Students advocate for clean water.  In this water pollution lesson plan, students play the Peace Corps Challenge Game, discuss the effects of polluted water and write a letter to the mayor of Wanzuzu highlighting the situation of...

Young scholars prune a tree.  For this gardening lesson, students select a shrub or tree that has a lot of flower buds and use sharp pruners to cut sections of branches.  Young scholars place the cuttings into cool water and...

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...

The scientific explanation of seismic waves is detailed in the introduction. A fictional scenario is also provided for your class to discuss. Pictures and handouts that are meant to be included, however, they are not accessible....

Young scholars investigate friction force on a variety of objects such as bricks and cardboard boxes. They use a force probe to collect data on the changes in force required to drag the objects across a variety of surface types.

Students investigate magnetic forces. In this electromagnetic lesson, students explore magnetic forces, magnetic fields, and the movement of current through a variety of activities.

In this energy activity, students complete a chart on the three types of heat transfer and their causes. Then they explain why all of the radiation directed at Earth does not reach the surface. Students also explain the factors in the...

Students learn how a pendulum works in the concept of an amusement park ride. In this pendulum lesson, students are introduced to Newton's first law of motion and how it works in an amusement park ride. Continuous motion and inertia are...

Students investigate the relationship between work and mechanical advantage. In this physics lesson, students calculate the work and efficiency of pulleys. They identify the different types of pulleys.

Ninth graders operate a model to observe the type of motion that occurs at a fault during an earthquake. They explore the effects of several variables. Students measure movement, calculate averages and plot and graph information.
