Fourth graders conduct a lab activity that measures the factors that change the swing rate of a pendulum. They create a hypothesis and test it during the experiment. They record their observations using the recording sheets and journal...

Students observe individual bones that comprise the neck portion of a chicken's backbone. After cleaning the bones of tissue, they examine the dried vertebrae and observe how they are adapted for support and protection.

Third graders examine the phases of the moon. In this moon phase lesson, 3rd graders listen to a read aloud of The Moon Seems to Change by Franklyn M. Branley and discuss the phases of the moon. They complete a moon phase calendar and...

Students design and conduct an experiment on Galileo's Rule of Falling Bodies. In this physics lesson, students collect and analyze data. They create a presentation and share it with the class.

Learners use this introductory lab using a tennis racquet, however it is very difficult to study because of the strings and the racquet stretch so little and so quickly during a match that students were unable to make simple...

Students identify and classify magnetic and nonmagnetic materials and metals. After determining which materials and metals are magnetic, students create a data table and classify items by two different criteria. Students e-mail various...

Students examine static and current electricity, and discuss what their lives would be like without electricity. They listen to a teacher-led lecture about electrons and atoms, and explore static electricity using a comb or a balloon...

Student design and build Lego vehicles that drag given amount of weight up an incline. They show how this demonstrates Egyptian methods of pyramid construction.

Students explore the concept of density by trying to make a penny and other materials float.

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...

Third graders experiment with heat through investigations. They rub objects together and compare the relative differences in the amount of heat given off. They write in their journals about the results they find.

Third graders examine the concept of work as the movement of an object through a distance. They define gravity and determine what type of work is caused by gravity. They measure how far an object is moved by a force. They make a...

Students complete several worksheets about machines.  In this machine lesson students complete several handouts that describe the different machines  and how pulleys work. 

Students study harmonic motion and its oscillation.  In this simple harmonic motion lesson students demonstrate a series of regular oscillations and explain the theory behind the experiment. 

First graders explore movement and motion. In this motion lesson, 1st graders how objects can move as well as how the Earth is in constant motion and the force of gravity. Students complete a coloring sheet.

In this electricity worksheet, students review topics related to electricity such as circuits, voltage, electric fields, and resistors. This worksheet has 21 problems to solve.

Students investigate the global importance of the African and Asian countries that export petroleum. They access the OPEC website and research this organization. They answer questions and write an essay about alternative energy sources.

Students design and build a solar concentrator. In this physics lesson, students evaluate their design and convince everyone why theirs is the best. They create a presentation and share it with the class.

Students describe how electric charges exert forces on each other as well as compare the strengths of electric and gravitational forces. They distinguish between conductors and insulators. In addition, students examine voltage and...

Students understand the destructive force of a tornado. They learn the role of a thunderstorm in the creation of a tornado.

Students identify Newton's Laws of Motion. They students explore Newton's Laws of Motion and apply the second law with a classroom activity. The videos will provide visual examples of the effects of gravity while riding on a roller coaster.

Students explore the theory of simple harmonic motion (SHM) by performing hands-on, practical application experiments. In this harmonic motion activity, students use strings of various lengths and bobs of different weights to create a...

Fourth graders explore magnets as fundamental parts of generators and how they are used to produce current electricity. They distinguish between the north and south pole of magnets and the difference between repel and attract. Students...

Fourth graders choose a simple machine and write about they way they believe it will work. Students experiment, write down procedures used and record observations. They will find a picture of the machine and add it to their report.
