Learners experiment to determine the effect of light on cyanobacteria movement. They graph the data of the experiment for further analysis. They watch a time-lapse video of cyanobacteria motility at a NASA website.

Students list sources of phosphorus in soil. They explain how phosphorus is removed from the soil and used by plants. Students list the symptoms of insufficient or excess phosphorus. Students perform experiments to examine the effect of...

For this space science worksheet, students use the clues at the bottom of the sheet to solve the crossword puzzle on our sun. They identify the cooler and visible surface areas of the sun, as well as what sunspots are on the sun.

Young scholars study the vent and non vent deep sea and see the differences in habitats.  In this investigative lesson students complete a worksheet and work in groups.

Fourth graders explore landscapes. In this landscape lesson, 4th graders investigate different elements of landscapes. Students design a visual presentation using photographs taken during a nature walk.

Students explore the different parts of the Cassini spacecraft. In this space science lesson, students create a model of the spacecraft using food products. They compare and contrast their model with the real one and evaluate its...

What is it like in the desert? Inform your class on what makes a desert, the type of climate they'll find there, and the interesting plant and animals that live in the desert environment. This is a text-rich presentation that will...

Maintaining a garden is an ongoing responsibility. This resource follows a series of activities in a unit that resulted in the planting of a rain garden. What you will find here are general instructions for watering, weeding, pruning,...

For this plate tectonics worksheet, students review concepts such as the types of plate boundaries, the concept of continental drift, sea-floor spreading, earthquakes, and plate tectonics. They match 30 terms with their definitions.

Students investigate where volcanos come from. In this volcano lesson, students watch videos do Internet research and participate in experiments to discover the cause of volcanos.

Students observe real fossils. In this science lesson, students make their own mud fossils by pressing material into the mud and letting it dry in the sun for 3-4 days. Students then get the fossils out displaying their mud...

Students demonstrate an awareness of air as a substance that surrounds us and takes up space, and whose movement we feel as wind. They predict and describe how local weather conditions affect living things, including themselves.

In this rock cycle worksheet, students review major concepts related to rock formation by answering 15 multiple choice questions and matching 15 terms to their definitions. Students identify 7 rocks as metamorphic, sedimentary, or...

Fourth graders study the components of soil. They observe the basic components of soil and relate the components to plant growth. They record color, texture, and kinds of materials on their profile log (light color, denser, grittier -...

Students examine core samples from Mars and discover what they can use it to tell the history of Mars.  In this core sample lesson plan students create and analyze their own core samples then eat them at the end.

In this environmental issues worksheet, students are given 10 current topics that are problems in our environment today. They complete sentences about each topic by filling in the blanks with the appropriate terms. Some of the issues...

Second graders watch demonstrations and conduct experiments that show the three different types of rocks: igneous, sedimentary, and metamorphic.

Sixth graders view an animated program showing how the continents fit together millions of years ago. In groups, they compare and contrast the distribution of rocks and fossils based on how the continents fit together. After reading a...

In this rock formation worksheet, students read a 2 page detailed text about rocks and their formation. Students then answer 15 essay, matching and multiple choice questions about the information.

Students relate meteorites to the mantle and crust of asteroids.  In this planetary lesson students complete experiments to model the separation of light.

In this rocks worksheet, students compare and contrast the 3 types of rocks: sedimentary, igneous, and metamorphic. Students complete 1 graphic organizer.

Sixth graders create a KWL chart about microorganisms. In this biology lesson, 6th graders create and label a diagram on a microbial mat. They investigate the processes involved in the carbon, oxygen and sulfur cycles.

Second graders discuss the geologic rock cycle and work with their group to simulate creating a sedimentary rock. They conduct an experiment that demonstrates the sedimentary process and draw the steps of the rock cycle.

Learners create an ecosystem in a jar to show a model of the water, carbon, and nitrogen cycle. Working in small groups, they research and present orally the information they find on this cycle.
