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.

In this Earth's environment worksheet, students complete a crossword puzzle given 35 clues about a variety of topics related to our Earth. Topics include ecosystems, precipitation, biomes, energy transfer, soil, weathering and rocks.

Using the NASA website, class members try to determine if changes could be detected in cloud cover, temperature, and/or radiation measurements due to the lack of contrails that resulted from the halt in air traffic after the attacks...

Students introduced to the interior structure of the Earth. They explore how the Earth's interior is broken down according to both it's physical properties and it's chemical composition. Students explore how convection currents within...

An incredibly colorful PowerPoint presents all the facts and definitions about waves that you could need for beginning physical scientists. There are several useful links to online animations of wave action. This may have been produced...

In this bicycle worksheet, students learn how the gears of a bicycle transfer energy. This worksheet has 2 short answer questions and 5 problems to solve.

High schoolers investigate the meaning of c2 in E=mc2 by measuring the energy delivered by an object falling at different velocities. They state that kinetic energy is the energy of an object in motion. Students illustrate how kinetic...

Students examine how heat moves from substance to another.  In this heat absorption lesson students identify ways that heat is transferred and analyze data.

Students quantify the relationship between temperature, energy and heat and define an endothermic reaction. They measure the energy change caused by dissolving one mole of ammonium nitrate in water.

Young scholars read about the green house effect and how our environment is deteriorating and what we can do to help it. In this green house effect lesson plan, students conduct a home and school energy audit, and create a rap.

Students build a refrigerator that does not require electricity. In this environmental science lesson, student consider desert dwellers of Africa who have no access to electricity. Students use flower pots, sand and water to study the...

In this science:  heat quiz worksheet, students answer ten questions, not interactively, about heat, water and temperature with the answers at the bottom of the screen.

Students create a rocket using Alka-seltzer of baking soda and vinegar. In this physics lesson, students identify the factors affecting the length of time the rocket is propelled. They relate this activity to actual rocket launched in...

Students examine physical change with different temperature and solvents. In this elements and compounds lesson, students conduct experiments to discover what happens to the mass of a substance when is undergoes a physical change.

Students study global warming by communicating the problem, process and solutions.  In this global instructional activity students use graphs, research and write a critical stance on natural disasters.

Not a lesson in the traditional sense, this is a collection of resources with which you can craft a lesson on metabolic processes. It includes an outline of topics, some brief discussion, and a large array of animations, images, and...

In this early childhood science worksheet set, young scholars study the importance of water, and determine the difference between themselves and water dwellers. They look at adaptations, river life, rainforest life, food chains,...

Students examine ways positive and negative charges are attracted and repelled by watching teacher demonstrations, and complete activity sheet related to classroom demonstration activities to prove proficiency of knowledge of...

Sixth graders discuss and describe consumers and producers. They discuss and describe predator-prey relationship. Students review food chains. They form a circle, and each student is given an ecosystem card. Student at the top is given...

Students determine the effect of temperature on the motion of particles. They study the difference between particles in a gas, liquid, and a solid and see how the characteristics of solids, liquids, and gases can be explained by particle...

Young scholars use authentic satellite data to produce plots and graphs of sea surface temperature as they explore the seasonal changes of the Gulf Stream.

Young scholars explore the importance of the Gulf Stream. Using a NASA satellite images, they examine the sea surface temperature. Students collect the temperature at various locations and times. Using spreadsheet technology, they graph...

Students use the NASA website's Live Access Server to create a graph of surface temperature at two locations on earth. They analyze the data and then answer specific questions provided in this lesson. They also examine and compare the...

Students review the process of heat transfer. In groups, they complete experiments in which they determine if a peanut holds enough energy to heat up water. They also calculate how much heat is given off by the peanut and record their...
