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,...

Don't waste any more energy trying to find a great resource on energy. The third installment of a 25-part Energy Systems and Solutions unit focuses on energy use in pupils' lives. They consider how their daily routines consume energy and...

What energy conversions occur in the operation of a device? Small groups investigate devices and the energy conversions that occur. The groups create energy flow diagrams with added conversion processes for each of the devices...

Radiation has numerous real-world applications, some of which are relatively safe while others can be extremely hazardous. In this nuclear chemistry project, young scientists choose a practical use of nuclear reactions to...

Students conduct lab activities, computer visualizations, and other various forms of research in preparation for a role-play activity in which they assume the identities of advisors to various heads of state on the subject of global...

What locations on Earth get the longest number of hours of daylight in the summer? Hint: It's not the equator! Use real-world sunrise and sunset data to develop trigonometric models that can be used to estimate the number of hours of...

What can a Ganesh statue, hand ornament, and print block tell you about India? Introduce your learners to the geography, history, and culture of India by analyzing primary sources and using the well-designed worksheets provided in this...

Let there be light. The last installment of a seven-part series has pupils conduct an experiment on light attenuation through different numbers of transparency sheets. They then relate the results back to how X-rays measure bone density.

Turning white light into colors only takes a little scientific know how! Young scholars create their own spectroscope in a hands-on activity exploring the properties of light. Using a diffraction grating, they discover how white light...

Sometimes it's okay to eat your science experiment. A hands-on activity has pupils create models for algae to learn about its cellular structure. The best part of the experiment? The resulting juice-filled gels are edible—yum!

Climate affects populations in different ways. Scholars research extinct organisms and mass extinctions in part three of the 10-installment Discover Your Changing World series. They create graphic organizers, then fill in the...

Ask your class to concentrate their energy on affixes! Pupils match various affixes to their meanings in a memory-style game until all the cards have been gathered.

Students evaluate various everyday energy conversion devices and draw block flow diagrams to show the forms and states of energy into and out of the device. They also identify the forms of energy that are useful and the desired output of...

This activity is a way for students to discover that they already know a lot about energy through their own life experiences. As active consumers of various forms of energy, they are aware of energy purchases for electricity, home...

The Energy Systems and Solutions unit brings students through the exploration of science and engineering concepts as they relate to energy issues in everyday life. Issues surrounding energy production and energy consumption provide a...

An excellent page from the Colorado State University with a heavy mathematical emphasis. Each form of heat transfer--conduction, convection, and radiation--is defined, compared, and contrasted. Mathematical equations governing the rates...
