A video and laboratory investigation are highlights to this lesson on acidification of ocean water due to increased atmospheric carbon dioxide. Using bromothymol blue (BTB) as an indicator, pupils analyze the amount of carbon dioxide...

As an anticipatory set, biologists listen to the story of Ruth Patrick, a scientist who used algae to detect water quality. They observe a demonstration of osmosis and diffusion. In their lab groups, they place Elodea stalks in...

Students explore decomposition and soil health by creating their own garden.  In this agriculture activity, students build a "lasagna garden" with organic matter found in the area and plant perennials native to their region....

Introduce your earth science enthusiasts to the earth's energy budget. Teach them using an informative set of slides that include illuminating lecturer's notes, relevant vocabulary, embedded animations, colorful satellite maps, and a...

High schoolers examine the hydrologic impacts of drought. Humans can change the course of the water cycle, to some extent, to meet their needs, but can they do so without imposing risks on the plants and animals?

Learners are shown how dissolved oxygen enters the water. They are taught the difference between a water sample that has been exposed to the air and one that has not. Students brainstorm what organisms need to survive. They use dissolved...

Students explore botany by participating in a calendar class activity. For this plant observation lesson, students examine a diagram of a Brassica plant and identify its anatomy before planting their own seeds and viewing the changes...

What do a bicycle and the life cycle have in common? Cover this and more with the series of cross-curricular activities included in this plan. Learners do everything from making bracelets that represent the life cycle to checking out the...

Young scholars investigate the lives of frogs by completing several worksheets.  In this biology lesson, students discover the life cycle of a frog from tadpole to death.  Young scholars complete frog life cycle puzzle as well...

Students investigate relationships between plants and animals and how living things change during their lives. In this life cycle lesson, students split different types of seeds apart to see the beginning life stages of future plants.

Learners chart how milkweed bugs grow and change.  In this growth and life stages lesson, students read two stories and discuss how and why things grow.  Learners brainstorm what can be measured about humans, review and discuss...

Students understand how clouds are formed. For this cloud lesson, students participate in three experiments to make clouds. Students complete activity sheets for each experiment.

Students are introduced to the concept of acids and bases and arouse curiosity about acids and bases in daily life. They are introduced to the measurement of soil pH. Pupils are introduced to the effect of soil pH on nutrient cycling...

Students create a compost cake. In this gardening and decomposition science lesson, students review and describe the "nutrient cycle." Students create a compost pile, measure and record the dimensions and temperature of the pile, and...

Learners identity the components of electron transport system through role play. They explain the role of intermediate energy carriers to the production of ATP molecules. They describe the relationship of electron transport system to...

Students draw and label the four parts of a plant. They describe changes that are part of the common life cycle. Students follow various one and two step directions. They are asked to discuss that they can recall about plants.

Third graders observe various demonstrations dealing with the water on our earth, such as a comparison of the amount of salt water and fresh water on earth, then participate in a role playing activity in which they become a molecule of...

Students bag trees to determine the mass of the water given off in the evapotranspiration process.

Students engage in a lesson of investigating the amount of water that is transpired in a one day cycle. They conduct research to find the purpose of transpiration and find information to explain the value to a plant and explain how...

Young scholars explore the parts of a flower and pollination of flowers. In this plants lesson, students use an interactive whiteboard to label the parts of a plant and the functions of each part. Young scholars complete a worksheet as...

Young scholars consider the effects of topography on climate patterns. In this earth science lesson, students research weather patterns and make inferences of how the land forms may create different climates. Young scholars compare...

Young scientists roll up their sleeves and get a little dirty in this three-day earth science investigation. Following the scientific method, children monitor the growth of algae in pond water samples in order to determine...

If tap water is more acidic than ocean water, why are we so concerned about ocean acidification? The third installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program focuses on carbon dioxide levels in...

Students see that spiders have a life cycle, and reproduce by laying many eggs. We can count by ones, twos, fives, or as many as we want. They make two lists of animals on a chart.
