Third graders investigate the life cycle of the Monarch butterfly. They experiment with various tools to simulate the mouth parts of insects, conduct research, record their observations of butterflies hatching, write a play, complete...

Learners describe the characteristics of algae. In this biology instructional activity, students perform a series of experiment to explore algae. They investigate the basic things algae need to survive.

Students carry out an experiment to monitor diurnal fluctuations in dissolved oxygen, carbon dioxide, pH, and water temperature. They determine the CO2 and pH of the samples (and optionally, dissolved oxygen). Students complete their...

Students investigate the relationship between dissolved oxygen and organic materials and aquatic organisms. This is a 3-lesson series in which students explore dissolved oxygen and then design an experiment testing the effects of changes.

Young scholars compare and contrast algae and land plants. For this plant lesson students discover what algae and land plants require for growth. The young scholars discuss experimental design. The students experiment with different...

Fifth graders investigate the how water becomes polluted and how it effects the environment, animals, and humans. They watch a video and conduct experiments.

Lab groups set up an experiment to observe what happens over time in collected pond water when fertilizer, representing pollution, is added. This website does not include student lab sheets, but background information, materials, and...

Young scholars explore energy by researching fuel usage on Earth. In this fossil fuel lesson, students define fossil fuels, the energy created by burning them, and the impact on the environment when using them. Young scholars conduct...

Students examine and identify the characteristics of the four zones of the ocean. They discover the amount of diversity in marine habitats. They also explore the adaptations organisms have that have allowed them to survive.

Learners study the properties of ocean water and tides and learn about animals that live in intertidal zones. In this intertidal zone lesson, students participate in classroom stations to learn about fresh water and salt water, cold...

What's it like to be a deep-sea explorer? Tap into the imaginations of your fifth and sixth graders with a vivid lesson, the second part of a six-part adventure. Learners close their eyes and submerge themselves in an expedition aboard...

Examine a slug? Of course, what else would a 2nd grader do with it? Pupils use clues and go on a slug hunt, read a slug story, or make a cooperative group mural of a slug's habitat. While older learners catalog slugs, go on a slug hunt,...

Students examine the properties of bubbles by testing different bubble making materials.  In this scientific experiment lesson, students create a bubble brew with different soaps while observing the different strengths and sizes of...

Students are led through three activities to explore the effect of temperature fluctuations on the growth and survival of aquatic plants, clams, and shrimp eggs.

Students develop a test tube model of an oil spill in order to experiment with conditions needed for bioremediation. They apply the principals of experimental design by analyzing a research article on the EXXON Valdez bioremediation...

Students explore oceans. For this science lesson plan, students locate oceans, seas and continents of the world, identify ocean-related occupations, and complete activities pertaining to food chains as well as pollution.

Students conduct an experiment to determine whether plants need air in order to survive and grow. They discuss natural resources, analyze slides, and observe and record data from the experiment.

Students examine relationships and interactions between different types of water. They experiment with colored water of different temperature and salinity and discuss how the results relate to real ocean currents.

Learners use DigiScope technology to investigate Daphinia, popularly known as water fleas. They design, conduct, and report on an experiment to determine the effects of varying water temperatures on the heartbeat rate of Daphnia.

Students experiment observing a demonstration on models of density-driven currents which are typically found in an estuarine system of water flow. They compare/contrast water temperature and salinity to the formations of estuarine currents.

Students explore biology by conducting a nature experiment. In this pond examination lesson, students utilize recycled materials, play-doh and water to recreate a pond and its inhabitants. Students identify the different elements within...

Students conduct an experiment.  In this salinity lesson plan, students learn about sea ice, why it is important and how changing amounts can affect the sea.  Students conduct an experiment to find out the effects of salinity...

Students work together to examine water quality. They identify the indicators of water quality and complete an experiment. They discuss their results.

Students experiment with water density, temperature and salinity. In this water lesson plan, students observe how the coldest water sinks to the bottom of a test tube, and how saltwater sinks in comparison to freshwater.
