Students explore the solar cycle through a series of experiments. In this space science lesson plan, students construct and evaluate solar cycle graphs. They explain how this phenomenon affects the Earth.

Students study chromatography and how they can distinguish between the different pigments in a color.  In this chromatography lesson plan students separate a mixture of dyes in soluble ink then record the colors they see. 

Learners explore what chemical indicators are and use pH paper to determine if something is alkaline or basic.  In this pH lesson students manufacture their own soap.

Students work collaboratively to create, edit, and publish their own student magazine. The instructional activity suggests the use of iPhoto, a word processor, iPages, and digital cameras for the creative process.

Students examine color perception and how it relates to metamerism.  For this color lesson students complete a lab activity that shows them the three basic components of color perception. 

High schoolers investigate the carbon dioxide content of different sodas. In this chemistry lesson, students explain why PET containers are preferable than HDPE for soda bottles. They collect data and graph them.

Students examine the importance of vitamin c in their diets and the sources that it comes from.  For this vitamin lesson students complete hands on activities, interpret data and make a bar graph.

Students conduct a series of experiment on incandescent and fluorescent bulbs. In this physics lesson, students explain how they operate. They compare the efficiency and power rating of both bulbs.

High schoolers explore how rechargeable batteries work by conducting a series of experiments. In this physics activity, students discuss the benefits of using rechargeable batteries over disposable ones. They build their own battery...

Students investigate magnetic permeability and saturation. In this physics lesson, students explain how current carrying wire coils create magnetic forces. They interpret normal magnetization curves.

Students explain how E-bomb works. In this physics instructional activity, students simulate the effects of e-bombs on electronic targets. They discuss its potential harmful effects when used as a weapon.

Students explain the relationship between magnetism and electricity. For this physics lesson, students describe the transformation of energy. They create an electromagnet and investigate the factors affecting its strength.

Students explain how power is transmitted over long distances. In this physics lesson, students simulate controlling power flow in parallel transmission lines. They discuss several applications of wireless power transmission.

Students explore how allelopathy works in plants. In this botany lesson, students explain how this phenomenon affect other organisms. They read and analyze an article about allelopathy and discuss its flaws.

Students identify habitats and understand why they are important to our environment.  In this environmental lesson students design their own habitat, observe and record data on the impact their habitat has on the environment.

Students explain the importance of chlorophyll in plants. In this biology lesson, students extract chlorophyll from different plant sources using chromatography. They discover the different factors needed for photosynthesis to take place.

Students investigate the effects of acid and bases on dyes made with plant materials.  In this chromatography lesson students predict color outcomes and complete a lab activity on color combinations.

Seventh graders identify how to use sterile techniques when identifying plant pathogens.  In this plant diseases lesson students complete a lab activity in which they see how plant diseases are identified and classified.

Students investigate the composting process through a variety of experiments. For this ecology lesson, students discuss the benefits of composting. They examine how compost affect plant growth.

Students examine how to grow plants using a hydroponic system.  In this hydroponics lesson students identify the advantages and disadvantages of growing plants hydrologically.

Students identify the different leaf pigments and colors. In this biology lesson, students perform chromatography to separate them. They explain how light affects green leaf colors and causes falling leaves in autumn.

Students conduct a series of experiments on mulching. In this earth science lesson, students discuss the benefits of mulching on soil. They explore how different types of mulch affect plant growth.
