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...

Here is a nifty worksheet on energy transfer. Physics fanatics analyze a diagram and state whether or not friction is involved. They sketch bar graphs and draw energy flow diagrams for each system as well. Circular motion, movement up...

Young scientists play tag as they act out the food pyramid in the ocean ecosystem. Energy circles pass from the smaller prey to the predators and at the end of the activity, a data chart and analysis questions allow pupils to apply their...

In this heat transfer and phase change worksheet, students experiment with ice, salt, and milk to show the relationship between the temperature of a solution and its phase. Students turn milk from a liquid to a solid and graph the...

Beginning biologists demonstrate their grasp on cellular respiration, photosynthesis, and energy flow though ecosystems when completing this worksheet. Fifteen multiple choice and short answer questions test their knowledge. Because of...

This worksheet would make a nifty quiz on the laws of thermodynamics. Nine multiple choice questions assess high schoolers' understanding of energy transfer, specific heat capacity, phase change, fusion, and vaporization. It is short but...

Amateurs of alternative energy build a mini parabolic-trough solar energy collector and use it to heat water. Temperature is recorded over a three-minute period and the data is graphed and analyzed. Note that in order to paint aquarium...

In this wave energy activity, students read about the energy created by water movement and how it is utilized to create electrical energy through two ocean wave energy converters. They answer three critical thinking questions about the...

Calories are not tiny creatures that sew your clothes tighter every night, but what are they? A science lesson, presented at multiple levels, has learners experiment with heat, heat transfer, and graph the function over time....

In this energy worksheet, students complete a crossword puzzle by determining the terms associated with the 20 given clues. Students review alternative forms of energy in this worksheet.

Why do some items feel colder when they are the same temperature? How should you keep your soda cold? What makes the wind blow? These are just some of the things middle schoolers discover when completing a lesson on...

In this adobe worksheet, learners read about adobe soil and how it was used for building because of its insulating properties. Students complete 3 short answer questions.

For this biosphere worksheet, students identify the different levels of organization that ecologists study. Students complete charts, sentences, and answer short answer questions.

In this ionic bonding worksheet, students observe diagrams about ionic bonds and crystal formation. They answer 37 short answer questions about the properties of monatomic ions, polytomic ions and write correct formulas.

In this space probes worksheet, students read about radioisotope thermoelectric generators and how they work. Then students complete 3 short answer questions.
