Students are introduced to colorimeter on two levels. They investigate how to physically manipulate the colorimeters. Secondly, the students start on a pathway of discovery to one of the most important principles in analytical chemistry:...

Students, working in small groups construct scale models of the planets and solar system. They examine images of Mars and discuss what might have caused the features. They record facts about their planetary research in their journals and...

Put on those forest ranger hats for an engaging and informative lesson. Eager scientists study the makeup of a local forest ecosystem and then write a forest management plan. They consider many parameters including identification of both...

Students investigate surface tension using water striders. In this inquiry lesson, students develop a researchable question about the topic. They explain the environmental consequences of lowering water surface tension.

Students will develop goals for inquiry. They will also improve content area reading and research skills. The context of studying dinosaurs will help learners to distinguish from organisms that live presently and those from the past...

Learners examine the properties of a liquid that contains water and food coloring and a liquid that contains water, food coloring and a liquid detergent. They interpret their data, describe properties, and make reasonable explanations...

Third graders gather information by questioning, forming hypothesis, collecting and analyzing data, reaching conclusions and evaluating results, and communicating procedures and findings to others. Then they demonstrate an understanding...

Students describe migrations and life cycle pattersn of a key alfalfa pest, the Porato Leafhopper. They define the Economic Inquiry Level and Economic Threshold. Students evaluate data in relation to profit as it applies to IPM. They...

Students identify trees based from their leaves. In this leaf lesson plan, students use The Rocky Mountain Tree Finder by Tom Watts in order to identify tree leaves. They look for leaf shapes, veins, and structure.

Students conduct a number of experiments involving evaporation and condensation. They view and discuss a video about the water cycle and then design posters about the rain based on the book "Cloudy With A Chance of Meatballs".

Students will design and build a structure to support a rock. Students will use their knowledge of movement of objects to determine the proper base to be built to support their rock. Students will explore their natural area for...

Young scholars learn the importance of caring for eggs as they hatch chickens. In this egg hatching lesson, students observe what happens when eggs are hatched into chickens by completing a e-worksheet and watching a web based movie.

Fourth graders identify rocks in this discovery lesson by examining rock characteristics and processes. They identify basic properties of minerals and rocks. They revise their theories of the natural world, once they see and learn new...

Students investigate the concept of succession and plant community dynamics. They play a game in order to conduct multiple experiments while playing. The interest of the game is useful for keeping student interest throughout the activity.

Students investigate that chemicals may affect different people in different ways. They also realize that their perceptions of dangerous materials may not be realistic and that the news media may not provide all the information needed to...

Beginning biologists place a drop of food coloring into water of differing temperatures to observe the effect on the diffusion rate. They remove the shells from raw eggs and then experiment with osmosis over the remaining membranes....

Students examine potential contamination on the environment due to products and by-products of a new industrial process. Students conduct a lab that explores the economic differences between choices of pollution cleanup and prevention.

Students are focused on the big question: What makes a population grow and how could that growth stop? They use these concepts to help answer the big question: carry capacity, density dependent v. density, independent factors, predation...

Students rank a list of everyday risks to compare with classmates. They rate each risk on both its ability to be controlled and its observability in the environment. Results are graphed.

Students compare the perceived and actual risks of getting skin cancer, while looking at ways to minimize these risks. They may have very little grasp of the severity of the threat of skin cancer or be unaware of the increase in the...

Students identify possible sources of health risks, types of exposures, routes of exposure, and populations that could be affected after discussing water pollution and environmental health hazards. After discussion, students conduct a...

Your biology class plays the role of epidemiologist when a mysterious illness breaks out in Kildare, USA. Using interviews with doctors, patients, and local citizens, maps, the results from different materials sampling, they work to...

Whether your young biologists realize it or not, humans play a significant role in marine ecosystems. To help them understand this fact children first create graphical representations that show homo sapiens' place in marine...

Learners demonstrate safe ways to handle bacteria, prepare agar plates, and grow bacterial cultures. They identify different kinds of bacterial colonies, and devise a controlled experiment.
