By rolling marbles down a six-foot length of track, physical scientists determine how much energy is lost to heat. It is recommended that you opt for the foam pipe insulation track because more friction slows the marble, allowing...

A well-developed lab sheet guides physical science learners through an investigation of kinetic and potential energy. In small groups, collaborators discover whether or not the ramp height or mass of an object has an effect on the...

With Earth Day quickly approaching, as well as many science fairs, why not challenge your class to investigate geothermal energy or other renewable energy resources? There are five driving questions explored in depth here, as well as...

Emerging biochemists more fully understand the flow of energy in ecosystems as they explore the laws of thermodynamics and relate them to energy transfer in food chains. They also investigate heat loss from the human body and how...

Small groups use the engineering design process to build and test a vehicle capable of carrying 250 grams a distance of five meters. The design must allow for the storage of potential energy and turn it into motion,...

When an organism eats, how does food become energy? Young biologists follow glucose through the process of cellular respiration to the creation of ADP using a discussion-based activity. The resource also highlights conservation of mass...

A messy fountain is potentially an energy experiment in disguise. Groups investigate the variables in creating a fountain from soda and Mentos. The last activity in a six-part series on energy has the class observe the fountain in terms...

Technology or engineering teams are given a task to design, construct, and test the efficiency of a structure that will foster an even temperature throughout an entire sunny day. Intended as a long-term project, pupils research, plan,...

Toys are great for learning about physics. Scholars use Slinky® toys to study Newton's laws of motion and types of energy. After a little play, they then model longitudinal and transverse waves with the Slinky® toys.

Every muscle movement requires energy, but where does that energy come from? Scholars answer this question and more as they complete a worksheet. By following the directions, completing research, and discussing it as a class, they begin...

In this heat worksheet, students complete experiments with heat and answer short answer questions about the transfer of thermal energy. Students complete 4 questions, one chart, and one bar graph.

It's a jungle out there! Young biologists journey to Darien, Panama to examine the intricate relationships between the organisms that inhabit the jungle. Groups begin by demonstrating an understanding of energy flow in ecosystems, then...

Environmentally friendly engineering teams construct a water wheel and experiment with its speed and the resulting amount of weight it can lift. Consider following this activity with two more of the same title by the same publisher when...

Create an egg-citing study of energy. Pupils investigate the effect of height and mass on the overall amount of energy of a falling object. The fourth segment in a six-part series on energy uses a weighted egg falling from different...

Learners investigate how solar energy is converted into heat in part two of the 10-part Discover Your Changing World series. They build and test homemade solar cookers to boil water and cook rice. Pupils consider the impact of heat...

Heat-sensitive liquid crystal sheets are available in a variety of sizes and temperature ranges. Purchase a class set of hand-held sheets and color half of each with a silver permanent marking pen. Learners of light can hold them under a...

Mike and Kellie, a team of electrical engineers, demonstrate how to to design a contraption that accurately drops a marble onto a target. The materials needed and general instructions are provided on the website or via a downloadable...

There are many factors that affect how fast the glaciers are melting. A lab investigation has learners examine how the surrounding water affect the rate glaciers melt. They collect data from two samples of ice to determine how quickly...

Let the true colors shine through. Pupils conduct a flame test to identify an unknown element. Class members calculate and prepare specific molarity solutions of three chemicals. Using their observations of the colors emitted, they...

Get into the swing of things. Pupils use a pendulum to demonstrate the conversion of potential energy to kinetic energy and back. After measuring the speed of a pendulum and compare it to the calculated theoretical speed, they...

Adjust the melting time of ice without varying the temperature! Learners experiment with different materials to decide how the materials affect the rate an ice cube melts. They then connect their findings to the conductivity of each...

Entangle your life science class in learning with this collaborative food web activity. Using pictures of the plants and animals native to a particular ecosystem, young biologists work in small groups to construct visual...

Waxed paper, newspaper, or aluminum foil? Keeping an ice cube from melting may require one or more of these materials. Learners design a box that will provide insulation so an ice cube stays intact for at least 90 minutes.

Wind it up and let it go. Individuals build a basic spool racer in the second portion of a six-part unit on energy. After receiving three criteria, pupils modify their designs to meet the new challenge. Pairs compete against each other...
