Fourth graders explore air as a material substance. Through experimentation and discussion, they explore how air can be classified as a material substance. Students write three examples proving that air is a material substance in their...

Students find the percent composition of sugar in the gum. For this chemistry lesson, students calculate percent error from the experiment. They use dimensional analysis to convert between units.

Students perform 3 hands-on activities to help them explain the terms "crest" and "trough" as related to sound, water, and light waves. All three waves types have troughs and crests. The activities use toys to demonstrate the properties...

Students use a software program to create a food web. Using the web, they identify the path of energy using arrows and label organisms as either producers or consumers. They show and explain their food web to the class.

Students use the EcoKids web site to explore food chains and the associated terminology. They answer the questions about food chains and their importance. Students use the Kidspiration program to add information to an Animal Fact Web.

Third graders make parachutes to learn about gravity and the science process. For this gravity lesson, 3rd graders create parachutes and observe their flight in air. Students discuss wind and gravity for the activity.

Students complete their Sparky's Engineer Activity Book. In this engineering lesson, students are guided by their teacher in completing their Sparky's Engineer Activity Book which reviews what engineers make and what tools and materials...

Second graders create a hypothesis on what objects will attract to magnets. In this magnets lesson plan, 2nd graders use a computer program to create a hypothesis as to what will attract or unattract magnets. For an extension, they test...

Students explore DNA and restriction enzymes using fragments of DNA separated by electrophoresis on an agarose gel. They analyze the results to see "whodunit".

Students explain that air is everywhere and discuss how living things use air.

Fourth graders identify the characteristics of a simple physical and chemical change. They describe objects by the properties of the materials from which they are made and separate or sort items using these properties. Students explain...

In this chemistry 112 worksheet, students use their knowledge of chemistry concepts to answer the multiple choice questions provided. Students calculate the answers using the appropriate formulas.

Students set up and run the experiments they designed in the lesson, 'Population Growth in Yeasts,' using simple yeast-molasses cultures in test tubes. They demonstrate understanding that several environmental factors can contribute to...

Students examine body systems. In this biology lesson, students explore the roles of different body systems and discover the effects of smoking, drugs, alcohol, exercise, and good nutrition on human body systems.

Sixth graders investigate the concepts related to creating an understanding of how earthquakes occur. They participate in a variety of activities that are tied to each other and focus upon the principle of plate tectonics. Then students...

In this chemical reactions worksheet, students by comparing the chemical reactions of baking soda and baking powder. This worksheet has a graphic organizer and 7 short answer questions.

Second graders identify physical and chemical changes of matter. They distinguish between physical and chemical changes. They classify changes as physical or chemical.

In this equilibrium worksheet, students answer eleven questions about chemical reactions, equilibrium concentrations and endothermic and exothermic reactions. They write equilibrium expressions for chemical reactions and they explain...

Students investigate surface tension, adhesion and cohesion. In this surface tension lesson plan, students complete 3 activities to better understand the concepts of surface tension, adhesion and cohesion. Students add drops of water to...

Young scholars examine chemical changes to food. For this chemical changes lesson, students make foods and observe the changes. The changes are recorded in an observation journal. Young scholars photograph food they make at different...

Students examine the importance of good quality safety gear. In this investigative lesson, students will tests various polymers, collect data, and analyze the data to determine which polymer is best for safety helmets. They will design a...

Students identify the physical and chemical properties of matter. They review the types of matter. Students list the four states of matter (Solid, Liquid, Gas and Plasma). They recognize and describe the different types of matter.

Students experiment to investigate static electricity.  In this static electricity lesson, students prepare a balloon head and draw a face on it.  Students rub the nose and the balloon moves toward the student rubbing.

Fifth graders compare physical and chemical changes. They perform a simulation experiment/activity that replicates what happens in the stomach as food is digested by stomach acids.
