Students explore, examine, experiment and study the energy believed to exist in the vacuum of space called zero-point energy. They design and build a machine and then place their machines to test zero-pointed energy into a competition.

Students investigate the process of erosion and factors that influence the rate of soil loss.  In this erosion lesson students formulate a hypothesis and analyze the results of their experiment. 

High schoolers recognize the benefits of ethanol and study photosynthesis.  For this ethanol lesson students complete an experiment that shows the procedure that starch can be hydrolyzed by salivary amylase. 

Third graders attempt to recall details about a person entering the classroom while they are involved in another activity. They test their skills of observation and memories by playing an interactive memory game.

Students analyze how a dichotomous key helps us explain and identify unknown organisms. They design and construct a dichotomous key, developing a list of three observable characteristics per organism.

Students investigate how warm air from a lamp affects a spiral of paper. They determine how the warm air rises while cooler air moves into take its place which creates wind in this Magic School Bus activity.

Students investigate a family profile and design a menu plan. In this consumer science lesson, students plan and prepare a weekly menu based on a family profile.

Third and fourth graders engage with a worksheet designed to help them differentiate between melting and dissolving. After reading an informative paragraph about the two actions, they consider four scenarios, and choose whether they...

Get the ball rolling and challenge your class to figure out how to make a ball move. The instruction segment is between two STEM activities devoted to doing just that. The first is simple and involves making a ball move from some...

Students use materials found at a resource table to design simple devices that will house instruments to take water samples from a tub of water. They design 3 instruments, each varying in density so that one will float, one will hover...

Students design and test paper airplanes to understand the concept of lift and how it affects flight. This technology-based Science lesson is excellent for use with upper-elementary and middle-level learners and uses spreadsheet software...

Learners, in teams, use given materials and their knowledge of Newton's First Law to create a device that will remove a sticky ping pong ball from a 16-oz. cup (which represents ketchup stuck in a bottle.)

Prove the Law of Conservation of Mass through a lab investigation. A well-designed lesson asks groups to combine materials and monitor indicators for chemical reactions. Measuring the mass of the reactants and products allows individuals...

Sixth graders design experiments to compare the amount of bacteria in river water to the amount in purified tap water. They explore how water purification removes bacteria and pollution from the water. Students examine the steps of the...

Fourth graders make a detailed observations about non-native and native grasses. They define reasonable policies that they expect to follow while working in the CRWA. Students list, in small groups, two treatments that have been used in...

Kindergartners learn about the ways force can stop and reverse motion. Several illustrations of children help them determine if the motion is causing an item to change direction. Next, they conduct an experiment to see if a water balloon...

Students design an experiment to evaluate the effects of various treatments on the nitrogen cycle in a freshwater aquarium. They are required to maintain a laboratory notebook of all work, measure the key analytes of the biosystem at...

Students develop their understanding of the effects of invisible air pollutants. In this invisible air lesson, students complete experiments with a rubber band air test, a bean plant experiment and by exploring engineering roles related...

Silver: more than jewelry, it's also a natural antimicrobial agent. An inquiry-based lesson asks collaborative groups to design and implement an experiment to test this property. Using samples of silver nanoparticles and a strain of...

Investigators collect the carbon dioxide produced when an antacid tablet is activated and identify what alteration produced the most gas. They also collect the gas in a buret in order to practice precision. Then they choose between two...

Young scientists take a close looks a samples of sand that come from three different beaches. They use microscopes to view the three slides, and make observations on a worksheet. At the end of the lesson, learners share their...

Here is a beautiful lesson on clouds designed for your 1st graders. Learners study three different types of clouds. They construct drawings of cumulus, cirrus, and stratus clouds. The Cloud Book, by Tommie dePaola is used to...

Students recognize dependent and independent variables in an experiment by practicing manipulation of variables; students practice designing experiments that contain the two types of variables.

Students examine the ways that technology effects our daily lives. Students also identify the processes involved in designing new technology.
