Students discover how hydrogen is created and extracted from water to use as an energy source. In this solar energy activity, students use pieces of aluminum foil as electrodes. Students attach one end of a wire to the hanger of the...

Students write a report about energy use. In this conservation activity, students interview adults about their use of renewable and nonrenewable energy. Students synthesize this information and write a report from the point of view of a...

Eighth graders examine the various methods of generating electricity and explain their commonalities. They determine what is the most common source of energy and what are the potential environmental health hazards due to electrical...

Students explore Earth science by completing energy worksheets in class. In this energy forms lesson, students identify and define a list of energy vocabulary terms and a K-W-L chart. Students view a matter video clip in class and...

To better understand how solar power can aid in creating desalinated drinking water, the class creates a model still. They will build a model of a solar still, make observations, and discuss how the process works. While the idea behind...

In the 19th activity of 22, learners determine if distance from a light source affects photosynthesis. Participants capture oxygen in straws and find that the amount of water the gas displaces is proportional to the rate of photosynthesis.

Dive into the power of the sun with a two-part lesson plan. Budding scientists model the greenhouse effect in a hands-on activity, and then participate in a skit that explores the earth's energy balances and what really occurs...

A cold seep is an area on the ocean floor where hydrocarbons leak from the earth, creating entire unique biomes. Learners explore cold seeps, photosynthesis in the ocean, and its limitations due to loss of sunlight. They further explore...

Radioactive pollutants can enter the body through ingestion, inhalation, absorption, or injection. The last lesson in a series of 36 introduces pupils to radioactive pollution. They study its sources, both natural and man-made, its...

By measuring the wavelength, frequency, and intensity of electromagnetic radiation, scientists determine the temperature, density, and composition of far away items. Scholars rotate through ten lab stations using a spectroscope at each...

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...

In a simple activity, physical scientists model nuclear fission using a droplet of oil. This can be used alone in a unit on different types of energy, or as part of the energy conservation unit produced by the Texas State Energy...

Hopefully you have a sensor interface for your physics class to use with graphing calculators when collecting data with a light sensor. If so, read on. Use this resource for learners to predict and then test whether or not the intensity...

Do spontaneous reactions really occur? Activity 12 in a series of 36 focuses on spontaneity of chemical reactions. Learners read about, discuss, and answer questions pertaining to entropy, explain the third law of thermodynamics, explore...

Seismologists use the direction and arrival times of p waves and s waves to determine the distance to the source of an earthquake. The engaging lesson has students line up to form human waves. Through different movements when attached,...

Both aerobic and anerobic respiration are introduced in this succinct PowerPoint. The chemical equations for both are included. The last slides give instructions for a lab activity in which pupils use a gas sensor to measure the...

Using a miniature coral reef aquarium kit, young ecologists model this unique ecosystem. They research various coral reef organisms and their niches, and they culminate the project by working together to write a report. Use this activity...

In this space science worksheet, students read an informative passage about radio waves and the possibility of sending messages in space. The passage describes a "Sounds of Earth" record on the Voyager satellite which contains messages...

Groups work together to design a lighthouse, from designing and drawing the wiring diagram, to creating prototypes of the switch and circuit, to envisioning and building a scale model along with a blueprint. By including different...

A more thorough presentation on coastal systems would be difficult to find! Detailed diagrams illuminate the offshore, shoreface, foreshore, and backshore zones of  beach. The sources and movement of sediments along the coastline...

A comprehensive lesson that takes a look at psychoactive plants with this one focusing on the opium poppy. Information about the history, culture, use, source and effects are discussed. There are weblinks to reliable sources about drugs...

Students explore the seasonal changes in Costa Rica.  In this dry season lesson students use the Internet to locate science data then generate data for precipitation. 

The vast majority of hydrocarbons humans use help fuel cars, homes, and provide energy. A comprehensive lesson teaches pupils all about hydrocarbons. From alkanes, alkenes, and alkynes to benzene, classes study the preparation of these...

Students measure the heat of fusion of ice. For this heat of fusion lesson plan, students use a calorimeter or Styrofoam cup and thermometer to measure the change in temperature of the water in their calorimeter. This allows students to...
