Young scholars investigate the concept of erosion by water in a problem solving activity. In small groups, they are assigned either sand, potting soil or rocks to construct a mountain that will hold up to a sprinkler can of water...

Pupils learn about the biological carbon cycle. For this carbon cycle lesson, students access the web site and mouse over the diagrams to follow the carbon cycle. They read about what happens to humans and plants during this cycle.

Students examine different organisms in various marine habitats. They identify any adaptations that have allowed the organisms to survive. They develop an imaginary organism and describe its life cycle.

Students brainstorm the different characteristics of potable water. In this general science instructional activity, students test several water samples and hypothesize which samples and brands they are. They discuss where drinking water...

High schoolers 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...

Learners synthesize the information they have been researching on water quality to evaluate the potential health risks in a region with arsenic contamination. They prepare and present a persuasive speech that incorporates visuals.

First graders discuss how water changes from liquid to a gas and back to a liquid as part of a continuous cycle. They conduct an experiment demonstrating that things happen to water to change its properties.

Begin a full lesson on climate change by demonstrating how carbon dioxide gas contributes to increased temperatures. Be aware that pressure inside the antacid-containing bottle in Activity 2 may cause the lid to fly off; keep viewers at...

Explore the Earth's different ecosystems through four lessons, an assessment, and extension activities. Lessons include informative text and step-by-step instructions to apply knowledge in interactive, and thought provoking ways; such as...

A lab activity is a great way to incite thoughtful questioning and scientific processes. Pupils will collect organisms with a Petri dish, make observations, sketch the organism, ask questions, then attempt to identify the specimen...

High schoolers are able to draw a diagram of the light reactions and briefly describe what is occurring throughout the process. They are able to explain where each reactant/product in the photosynthesis equation comes from/goes during...

It's an extravaganza of excrement! Do your pupils understand that waste doesn't really go to waste? Introduce the nitrogen cycle with an interesting instructional activity and lab from the K20 series. The activities include a look at...

Student make at least FIVE rocks. They write predictions about that will change and occur. Each student receives a small cup that they label with their name to hold their rocks.

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...

Learn the science behind ocean acidification and its effects on ocean wildlife. Young scientists conduct a laboratory investigation that monitors the acidity level of water. While burning a candle, learners capture the carbon dioxide in...

Sixth graders identify the steps of the different cycles of matter, while learning to use WP utilities.

Even rivers have tides. Older elementary schoolers will discuss the Hudson River and how weather, water craft, and the ocean cause tidal fluctuation. They will examine a series of line graphs that depict tidal fluctuation, then analyze...

Students understand that most substances may exist as solids, liquids, or gases depending on the temperature, pressure, and nature of that substance. This knowledge is critical to understanding that water in our world is constantly...

Pupils engage in a discussion on watershed management.  In this ecology lesson, students consider the role of forests in water quality.  Pupils incorporate lecture material into a class room discussion and...

First graders learn the basic needs of plants and identify geometric shapes while planting a fall garden. Combining math and science in one lesson, the resource guides kids through starting their class garden as they...

Learners hypothesize the role of rocks, soil, and water by observing a terrarium and create a model to explore the water cycle. This is part of a five station set up.

  Learners observe a leaf and discuss the way that water is released from a leaf through its stomata.  For this water cycle lesson, students calculate how much water leaves produce from a whole tree.     

Students investigate the weather by reading children stories.  In this weather observation lesson, students read Cloudy With a Chance of Meatballs and several other stories about weather before they create a KWL chart....

Middle schoolers collect snow samples around their school. They explore the concepts of density and phase change as well as the math skills of measurement and statistics. Students explore the water cycle through an interactive, down...
