Students observe water birds feeding at a local wetland, record what they see, and construct an appropriate menu for a "Waterfowl Cafe." They also play a "flocking" game.

Students make an eco-friendly vehicle to help make transportation better for the environment. In this transportation lesson, students learn how transportation inventions are bad for the environment. They then see how engineers have tried...

Purifying air and water, providing soil in which to grow crops, and moving water through its natural cycle are all services an ecosystem provides that benefit humans. Lesson four in a series lets learners explore and discuss the value of...

Ecosystems provide many things humans not only use but also need in order to survive. The last activity in the series of seven introduces scholars to the idea of ecosystem services, that ecosystems provide humans with many things we...

A nicely formatted set of slides that logically follow and define the structure and function of the genes in Bacteria. The repressor proteins and other gene regulators are listed and diagrams support the explanations of their function on...

An excellent review of the very specific stages of mitosis, the detailed slides start with explanations of the directionality of DNA and then develop the concept of daughter strands. The intricate diagrams are intended for experienced...

Second graders examine the interdependence of organisms using the book "Go To Sleep, Gecko!" They examine a variety of food chains, listen to the book, and answer story comprehension questions. Students then conduct research on food...

Students investigate the effects of pollution on marine ecosystems. They read and discuss an article, identify the effects of pollution on marine life, conduct research on local nutrient pollution, and conduct local water quality studies.

Students design a solar still and purify water.  In this earth process and design lesson, students observe how the heat of the sun helps to purify water. Students analyze why this could be helpful on a desert island.  Students...

Let nature guide your engineering designs. By taking apart a flower, pupils learn about reverse engineering. They use the results to brainstorm designs for new products or ideas. This is the seventh installment of a nine-part Life...

Getting water to a tap requires an understanding the fundamentals of fluid flow. Groups design, build, and test a piping system to get water from the source — a five gallon bucket — to a tippy tap. The objective is to be able to...

Don't drop the ball on the resource ... drop an egg instead! A teacher-led demonstration has the class consider how to drop eggs into glasses when a tray is in the way. Hint: If you've ever seen a magician pull a tablecloth off a table,...

Don't melt away! Pairs investigate different insulation materials to determine which one is better than the others. Using a low-temp heat plate, the teams insulate an ice cube from the heat source with a variety of substances. They...

Budding scientists collect and compare particulate exhaust from four different vehicles. They discuss how cars contribute to air quality. To get the most mileage out of this resource, have learners complete the optional step 5, in which...

Many historical innovations were created for the common good. Get your students ready for life as a critical thinker with this lesson which defines the differences between innovation and invention. They will conduct Internet research,...

Students create an indoor container garden. In this container garden lesson, students explore seed germination. Students discuss edible seeds.

Marine biologists research sea ice communities. Assign some groups to construct paper models of sea ice communities in winter, and some to construct models of them in summer. The instructional activity is simplistic, but the Internet...

Elementary schoolers investigate how fossils are created by reproducing the process of creating an impression and filling it with a hardening material. The art lessons from this source are just fantastic! The lesson plan is well-written...

How many animals can live in a climate as cold as Mount Everest's? Find out with a science activity all about biodiversity. Activities include research, presentations, group work, coloring maps, and a simulation of a food web.

Students conduct a close examination of the atom's electrons, and discover how to theorize the energy levels, observe the brightness of light, classify colors, and measure temperature.

Students compare and contrast the processes of photosynthesis and chemosynthesis. They identify and describe sources of energy used by various organisms for chemosynthesis.

Second graders explore solar energy. In this science lesson, 2nd graders use hand lenses to see that light energy can be converted to heat energy.

Third graders examine the power of solar energy. In groups, they create their own pizza box solar oven to discover the power of the sun and how it is a source for heat and light. To end the lesson, they use the internet to examine...

Students study an article on Gamma Rays.  In this investigative lesson students study the energy and wavelengths of gamma rays and the theories behind them.
