Students describe the roles of controlled, manipulated and responding variables in scientific research. They also identify biotic and abiotic interactions affecting the makeup of a plant community.

Students examine different variables and their effects on weight gain in mice. They consider the validity of relating the results in mice to humans.Finally, they discuss the ethics of using animals in experiments.

Pupils are introduced to the concept of biodegradability. In groups, they use the internet to research the types of materials that affect the process. They collect materials from their local community and develop an experiment to test...

Students utilize the process of scientific inquiry and technological design to explain thrust, weight, lift and drag in flight. They design an "airplane" to test the "mechanics" of flight. In addition, they brainstorm and sketch a design...

High schoolers determine the specific heat of unknown metals. based on their hypothesis and design proposal. They analyze the findings of the specific heat of the unknown metals. Students complete this by questions, hypothesis,...

Young scholars discuss whether there are variations in absorbency and wet strength amount different brands of paper towels. They compare advertising claims and personal preferences and perform tests to reach a conclusion of which brand...

What does the graph mean? Pupils view 10 graphs and determine whether they are possible based on their contexts. The contexts are distance versus time and profit versus time.

Solve your equation and prove it, too. Young mathematicians solve linear equations using an interactive. They must input a property to justify each step of their solutions.

Using a famous children's story as the hook, learners explore the concept of changes in matter. First, they make a cake similar to the one made by Alice in the story Alice's Adventure in Wonderland by Lewis Carroll. Next, they let their...

Fifth graders study the scientific method and understand how to apply it.  In this "thinking like a scientist" lesson students complete several activities.

High schoolers collect and record data. They identify sex of butterflies. They make conclusions based on collected data.

If your future physicists know how to construct simple circuits, include resistors, and use a multi-meter to measure voltage, then you might employ this lesson on Ohm's law. Each lab group investigates the relationships among...

Ninth graders investigate the techniques of culturing bacteria. They culture bacteria using agar plates. Students identify and describe some environmental conditions that effect bacteria growth.

Students collect and graph data and use the internet to research the skeletal muscles.

Students use the Internet to research current and past snowpack levels and river gauging station readings. They determine the relationship between snowpack and river flow. They predict future river flow.

Students observe and count bird sightings around their schoolyard throughout the school year.

Students watch a demonstration to ascertain why a soda can crushed. They make observations and hypothesize about why a soda can crushed and relate the difference in pressure to its affect on objects around us (soda can). Explanation is...

Students measure, record, and graph the force of moving a block of wood along sand paper. In this friction lesson plan, students read a spring scale, collect data, construct a graph, and propose a model to explain how fiction works.

Students collect and identify plant species from campus, create a home herbarium, and compare with the plant species from school.

Seventh graders learn about John Kellerman, a youngster who was born with Fetal Alcohol Syndrome. They learn how alcohol and pregnancy doesn't mix.

Pick and choose which activities to include in this crime scene investigation. Junior detectives can examine fingerprints, DNA, blood samples, or bone structure.  The plan suggests you have teams solve a mystery, but it does not...

A terrific lesson focused on the design process. It begins with a presentation, "Design: Solve a Problem," which lists the steps of the process and then introduces the specific challenge: to build a device that measures wind speed....

Questions that can be used in a lesson on Earth's radiation balance are suggested in this resource. It is not a lesson plan, per se, but it is a list of questions for stations within a "Gallery Walk" lesson. The link to how Gallery Walks...

Students experiment to discover how different variables affect the water cycle. They do hat flow experiments and construct a computer heat flow model.
