Concentrate to determine the best reflector design. Pairs use the engineering design process to build a reflector to increase the current output of a photovotaic panel. Teams arrive at a final design and present it to the class along...

Introduce teams to quantum dot solutions with an activity that has them expose solutions to a blacklight, observe the colors, and take measurements. Groups graph the data and analyze the dependence between particle size and...

Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

Diagrams with annotations are shown on each of these eighteen slides, which summarize the processes of respiration. The focus is on the 3-step oxidation process and the Krebs cycle.  Students should be able to follow these slides...

If you need a clarification of the electron transport chain for your pupils, then this slide show will be a great help. There are nice images of the membranes and elaborations of chemiosmosis which will provide learners support with...

How do green plastics reduce waste and environmental pollution? Budding scientists create and test a variety of compounds used in green plastics during an insightful experiment. Beginning with startling statistics and ending with...

I think I lost an electron. Are you sure? Yes, I'm positive! Starting with a hands-on demonstration and problem solving activity, young scientists define vocabulary related to circuitry and currents. Then they build their own circuits...

Discover the connection between electric current and magnets. Scholars create electromagnets by passing a magnet through a coil. They experiment with different materials to determine the variables that affect the strength of the current.

In this biology worksheet, students explain where the energy of food originally came from. Then the explain one of the principal chemical compounds that living things use to store energy. Students also describe how ATP and ADP differ and...

Young scholars harness the power of the sun to design, construct and evaluate a solar-powered model car of their creation. They race their cars in a "Solar Sprint" race modeled after the National Renewable Energy Laboratory's Junior...

Students explore oxygen properties by conducting a cell experiment in class. In this respiration lesson, students discuss the process of breathing and how oxygen is inhaled before carbon dioxide is exhaled. Students utilize yeast, water,...

Students discover the types of batteries and their uses. They experience static electricity by rubbing glass jars and using it to raise their hair. After discussing the importance of recycling batteries and using ones that are...

In this prokaryote worksheet, students answer ten questions about prokaryote cells and they color a diagram of a simple bacteria cell and its structures.

Learners explain the relationship between magnetism and electricity. In this physics lesson plan, students describe the transformation of energy. They create an electromagnet and investigate the factors affecting its strength.

In this atomic spectra worksheet, students answer eighteen questions about wavelengths of light, the emission spectrum, energy of photons, the frequency of electromagnetic radiation and electrons in the excited state.

Students investigate the energy released by a peanut and a piece of a walnut. In this catabolism and calories lesson plan, students burn a peanut and a piece of a walnut and measure the temperature of the water before burning and after...

This PowerPoint includes a game with ocean graphics in which two teams answer increasingly difficult questions about animals. Topics covered include plant and animal cells, animal adaptation, and similarities and differences between...

Students design and construct a battery (electrochemical cell). They works in a team to design and construct a working battery and is responsible for a labeled diagram of its operation. This engaging lesson stimulate their creative juices!

In this space radiation worksheet, students read about the various types of radiation humans are exposed to. Students answer 5 questions based on the reading. They calculate the amount of energy gained when exposed to a certain amount of...

Students engage in an interactive "hot potato" demonstration to gain an appreciation for the flow of electrons through a circuit. They role play the different parts of a simple circuit and send small items representing electrons (paper...

In this online electricity worksheet, students are asked 10 questions about electric current and battery energy, an online answer key provided.

Students use a battery, wires, small light bulb and a light bulb holder to learn the difference between an open circuit and a closed circuit, and understand that electric current only occurs in a closed circuit. They describe the...
