Students discover the different alternative fuel sources. In this biology lesson, students identify the different stages of the carbon cycle. They explain the pros and cons of using alternative energy.

Students use heart rate monitors and complete a swimming and running test. These tests allow students to obtain personal data, to manipulate the data through calculations of various parameters, and to graphically represent the data.

Learners complete cycle ergometer test to enable them to discuss their potential in each of the three events in a triathlon. They use their own dataset to make decisions as to their abilities in each sport.

Middle schoolers participate in activities in which they model different disabilities. They discuss their experiences as a class. They work together in groups to discuss how to improve an adaptive device.

Young scholars work together to design and build a paper rocket. They place a propellant in the contraption to make it fly. They discover Newton's third law of motion.

Students are divided into a group of hormones and a group of receptors. The hormones have to find their matching receptors, and the pair, once matched, perform a given action. This activity helps students examine the specificity of...

Students explore weight by building a spring scale and observing how it responds to objects with different masses. Each team of students can make their own spring scale by following steps which are specifically outlined in the plan. As...

Students are introduced to basic aerodynamics through a discussion of thrust and drag and a hands-on activity. They examine the forces of thrust, drag, air pressure, aerodynamic shapes and Newton's Third Law Of Motion.

Students work together to examine how different types of balls react to colliding with different surfaces. They discover the difference between elastic and inelastic collisions. They practice calculating momentum as well.

Students work together to create a simple conductivity tester. They discover the difference between conductors and insulators. They test different types of materials for their conductivity as well.

Students work together to discover the importance of charts while navigating. They complete a worksheet and practice reading maps. They create their own nautical chart to complete the lesson.

Students build parallel circuits, exploring how they function and looking at their unique features. They describe how current changes when batteries are added in parallel or removed from a parallel arrangement, demonstrate the process of...

Students explore how different textures provide varying amounts of friction to objects moving across them. They build a tool to measure the amount of friction between a note card and various surfaces by measuring the distance that a...

Students explore the fundamental concepts of electricity. They examine different circuit diagrams to study how electricity flows. They finish by creating their own simple circuit.

Students identify two major types of visible pollutants, smog, and particulate matter, They explain that air pollutants are generated during incomplete combustion. They measure and rank collectors from the most pollutants to the least...

Students observe a simple water cycle model to better understand its role in pollutant transport. This activity shows one way in which pollution is affected by the water cycle; it simulates a point source of pollution in a lake and the...

Students discuss the importance of water in our daily lives. In this physics lesson, students calculate the pressure of water tower systems. They investigate the effect of certain variables using a computer simulation.

Students design and conduct experiment to determine if weight added incrementally to an object affects amount of friction encountered when it slides across a flat surface. They graph data from their experiments, and calculate...

Students examine the concept of biodiversity. They toss coins to determine what traits mouse parents have and the babies traits as well. They predict what would happen to the baby mice if the traits of the parents were different.

Middle schoolers investigate the force of compression and how it acts on structural components through a hands-on group project. They use everyday products such as paper, toothpicks, and tape to construct a structure that will support...

Students research the concepts of center of mass and how to make different things balance. They make symmetrical cut-outs of different "creatures" and experiment with how they balance on a tightrope of string.

students analyze how oil is formed and where in the Earth we find it. Students take a core sample to look for oil in a model of the Earth. They analyze their sample and make an informed decision as to whether or not they should "drill...

Students explain that photosynthesis is a process that plants use to convert light energy into glucose. They summarize photosynthesis as a chemical process in which the plant uses carbon dioxide and water to form glucose and oxygen.

Middle schoolers use the Internet to study how water is treated to make it safe to drink. They use a tutorial on the U.S. Environmental Protection Agency's website to gain this information. They complete a worksheet for the assessment...
