Seventh graders explain the mechanism of digestion. In this biology lesson, 7th graders perform an iodine test to check for the presence of starch. They discuss how energy travels through the food chain.

Students explain how electricity is transferred from source to load without actual wires connecting the two. In this physics lesson, students explore how wireless electricity was discovered. They cite practical applications of this...

Students explore the nature of electromagnetic spectrum through a series of experiments. In this physics instructional activity, students determine how light behaves under certain circumstances. They explain how humans perceive colors.

Students work with a real optical spectrum of a gamma ray burst afterglow taken at the Keck Observatory. They measure the shifts of spectral lines, deduce the velocity of the astronomical object, and then use Hubble's Law to get its...

Eighth graders analyze physical change in mass. In this chemistry instructional activity, 8th graders describe, measure and calculate the amount of physical change occurring in mass before and after the change. Students should be...

Young scholars explain the four stroke process in internal combustion engines. For this physics lesson, students role play this process and present their reenactment in class. They draw and label the diagram of an internal combustion...

Learners explain the relationship between magnetism and electricity. In this physics lesson plan, 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 investigate the physics of heating and cooling through conduction, convection, and radiation. Working in groups, they determine the best way to cool a can of water and warm a can of water. Temperature is taken at five minute...

Students role play the movements that animals make to discover the importance of exercise in staying healthy and having energy. They mimic the hopping of kangaroos and the balancing of flamingos as they watch the animals perform these...

Students study life science. In this food webs and food chains comparison lesson, students examine the wetlands to discover the relationships that exist between the animals that live there. They participate in group activities and...

Third graders read, write, and listen to information about the sun and its effects on the Earth.as it relates to its axis, orbit, rotate, and revolution.  In this solar system lesson, 3rd graders examine how the sun...

Students read the story "Weslandia" by Paul Fleischman, define the term microclimate, gather and record data in various places on school grounds to establish the presence of difference microclimates, analyze and compare microclimates,...

High schoolers conduct a series of experiments on electromagnetic induction. In this physics lesson, students apply the right hand rule to determine the current direction and electromotive force. They test Lenz's and Faraday's law by...

Eighth graders explore the physical change of matter. As a class, they discuss their favorite super hero and determine if the hero undergoes a physical or chemical change. Students examine the change of state and phase change. In groups,...

High schoolers 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.

Students consider that under certain conditions in nature tend to remain the same or move toward a balance. They observe populations and determine the functions (e.g., de-composers, producers, consumers) they serve in an ecosystem. They...

Students demonstrate the greenhouse effect. They recognize that relatively small changes to our environment can stimulate significant climate changes. They determine that the "scientific method" is a process of testing hypotheses and...

Students calculate stoichiometrically the amount of carbon dioxide that would be emitted from burning a mole of varios alkanes that comprise fossile fuels. If the energy released from burning a mole of these alkanes is known, then the...

High schoolers examine hydrothermal vents. In this ocean lesson, students identify changes in physical and chemical properties of sea water caused by hydrothermal vents.

Students participate in experiments to visualize the differences between chemical and physical changes. They attempt to detect the five characteristics of a chemical change.

Students understand what physical adaptations are and how they help an animal to survive. In this adaptations instructional activity, students research four animals and then make an original animal that has adaptations to make them survive.

Second graders explain the relationship between energy and work. In this technology lesson plan, 2nd graders describe the different uses of machines in their everyday lives. They record observations and data in their science journal.

Students explain how battery chargers work. In this physics instructional activity, students discuss the two main ways that vehicles get charged. They build their own battery charger.
