Fourth graders examine the interdependence of the oxygen and carbon dioxide cycle in an ecosystem through a laboratory investigation. After a lecture/demo, 4th graders complete the lab in groups.

Learners play a game where half of them are deer and the others are components of habitat: food, water, shelter and space. They signify their needs by hand gestures and take what they need to their side of the game. They discuss real...

Students explain their role as consumers. They use a purchased calorimeter or make their own simple calorimeter to measure the energy content in selected foods. This interesting lesson really gets students thinking about what they eat.

High schoolers examine how to represent organic compounds three-dimensionally. They write a synthesis reaction for three demonstrations, and construct a three-dimensional structure using a molecular modeling set.

Learners identify the different parts of the circulatory system and their function. They work together to create their own model of the system and use it to determine the rate of blood flow. They answer questions related to their model.

Seventh graders read and follow the instructions on the worksheet. They make a table of their results. Students use about 100 cm^3 of water and ice mixture. They heat the water/ice with a Bunsen burner. Temperature is recorded every 30...

Seventh graders read the directions printed on their worksheet and follow them carefully. They set up a beaker with a tripod and Bunsen burner under it. They record the temperature of water every 30 seconds. Students graph the data and...

Students determine the energy content of various snack foods. They measure the temperature changes in various snack foods as the foods are burned in order to determine the foods' energy content. Students create graphs and data tables of...

Students work together to test the strengths of various types of magnets. After testing, they create a graph showing how the strength changes as the distance from the magnet increases. They discuss how forces can act from various...

Students work in small groups and use a hand-held vacuum pump with a balloon under the dome with some air. Another deflated balloon is attached to the end where the air goes out. As the air is drawn out of the dome the first balloon with...

Eleventh graders are introduced to the effect of gravity on plant growth. They describe the major processes and mechanisms by which plants grow, develop, and supply various products, including energy and nutrition, needed by other...

Students explore the major characteristics of the major animal phyla. They describe adaptive features that have contributed to the success of animals on land. Students explain how primate evolution provides a context for understanding...

Students interpret and analyze data.  In this middle school mathematics lesson, students conduct an experiment in which they investigate which solar collector, black, white, or silver, absorbs the most heat.  Students examine...

Students measure acceleration using a Picket Fence and a Photogate. In this physics lesson, students drop an object and measure the acceleration of the object free falling. They log their data using the TI.  

Students engage in a lesson plan that is concerned with the water cycle and different states of matter. They conduct research using a variety of resources in preparation for taking a quiz. Then students take the quiz in correlation to...

In this vocabulary worksheet, students read 5 different word lists. The word lists are divided by sounds. For example, one word list contains the sh, ch, th, and ng sounds.

In this chemical reactions worksheet, students review the law of conservation of mass, the principle of definite proportions, and balancing equations. This worksheet has 3 problems to solve.

Students explore mixtures and compounds. In this lesson, students do an experiment to distinguish between mixtures and compounds. Students complete ten different phases of the experiment testing many different substances. Students will...

Learners discover the properties of matter and how they change when composite materials are produced.  In this informative lesson students write up a question and procedure to an experiment then analyze and draw conclusions based on...

Students calculate the calories in food samples and plan a meal based on the calorie amount. In this calories lesson plan, students also devise a work out program to burn off the calories.

Students weigh objects using a triple beam balance. For this mass lesson, students use an inertial balance made with a metal rod to measure and graph vibrations of varying numbers of pennies in a bucket. References and discussion prompts...

Students move through five stations demonstrating Newton's Third Law of Motion. In this Newtonian physics lesson, students watch as the instructor uses a firecracker to demonstrate action and reaction. The students travel to five...

Students explore the Dollper effect by finding the frequency and velocity of sound.  In this velocity lesson, students determine the impulse during a collision by using their data and a software program.

Students explore simple machines. In this physical science lesson, students identify six simple machines, illustrate each and identify how these machines function or can be combined to create a compound machine.
