In this food energy activity, students rank the foods by the amount of energy they think the various food items have in them. Students then answer the 4 questions about food energy.

The climate at the equator is hotter than the climate at the poles, but why? The lesson goes in depth, explaining how the angles of illumination relate to the heating rate at different latitudes and seasons. Scholars use a strong lamp,...

Explore the connection of surface area to bonding within atoms. Learners complete lab investigations to model changing surface area with different sizes and concentrations of atoms. A flour fireball demonstration follows the labs to...

Energy conservers investigate gravel size to discover if it impacts the amount of oil recovered in the extraction process. 

Eleventh graders analyze and interpret an animated model of Earth’s rifting processes.  In this Earth Science lesson, 11th graders connect Earth’s rifting processes with the Earth’s surface in the Gettysburg battlefield. ...

After viewing short clips of unfortunate events, your class will consider two sides of a homeowner's court case, and then learn about the Marcellus shale deposit beneath the state of Pennsylvania and the hydraulic fracturing process. In...

Students examine the evidence that scientists have used to support the existence of global warming and the greenhouse effect. How the concepts have been developed and evaluated form the focus of this lesson.

Students examine the importance of good quality safety gear. In this investigative lesson, students will tests various polymers, collect data, and analyze the data to determine which polymer is best for safety helmets. They will design a...

Third graders learn how to use solar power.  For this sun, technology and energy lesson, 3rd graders learn how the solar power from the sun can give off energy, learn about solar panels, discuss their uses and benefits, and design a...

Students describe what global warming is, what causes global warming and the impact to our world. They study the threat of global warming and its relationship to the use of fossil fuels.

Eighth graders identify the different stages in the life cycle of a star. In this astronomy lesson, 8th graders read H-R diagrams and analyze data. The describe how the Sun's evolution will affect Earth in the future.

Students participate in experiments to visualize the differences between chemical and physical changes. They attempt to detect the five characteristics of a chemical change.

For this thermal decomposition of calcium carbonate learning exercise, students perform three experiments on calcium carbonate, make observations, and write the equations for each reaction. Students explain in detail what happened at...

Pupils try to determine how the Earth is heated by the sun and other sources. In groups, they identify the other sources of energy and discover why different parts of the world are heated differently during the year. They complete an...

Students identify the five major alternative energy sources. For this physical science lesson, students assess the advantages and disadvantages for each type of energy. They complete a concept map using information they researched.

How do temperature changes affect ocean currents? Scholars explore convection currents by demonstrating the flow of water in a baking dish. They use ice, heat, and food coloring to see currents. Then, they draw conclusions about their...

Thunder and lightning are so exciting! Your class gets to read all about it. This informational reading passage provides them with a scientific explanation of thunder and lightning. They read the passage, answer comprehension questions,...

On September 26, 1991, four women and four men entered the scientific experiment, Biosphere 2; the doors were sealed for two years in order to study the interactions of a biosphere. In the activity, scholars explore biospheres by...

Treat your class to a fun activity, complete with treats. Groups create a solar oven from a pizza box. They then use it to heat up some food ... that's what an oven is for, after all!

It's getting hot in here! The first in a series of six lessons has learners model nuclear fusion with a simple lab investigation. Groups collect data and analyze results, comparing their models to the actual process along the way.

Students determine crude oil can be separated into useful fractions by a process of fractional distillation. They write a balanced equation for the reaction between a hydrocarbon and oxygen.

For this element properties worksheet, students complete a crossword puzzle with 91 questions related to properties of elements and compounds.

Students examine the compositions and structure of diamonds. They conduct an experiment growing crystals, watch a video, and conduct Internet research.

Students develop an understanding of the decomposition process and the parameters which influence the rate at which it occurs.
