Time is growing short. Teams work together to identify physical properties of rocks in order to determine the properties that would best suit their cavern shelter design.

Demonstrate how ice floats on water and get the class thinking about why icebergs are so deceiving. Investigators then experiment with mixing water of the same temperature and water of different temperatures. Make sure to explain the...

Students use this activity to establish a new mode of reference to the conceptualization of time. To present hominid evolution in terms of millions of years and endosymbiosis of eukaryotes in billions of years carries little meaning to...

Learners explore erosion. Through multi-media and hands-on activities, students identify the effects of wave erosion and hurricanes on a barrier island. Learners watch a video and create a cause and effect chart of their observations. ...

Do your pupils have the misconception that environmental predators are "bad" and harm smaller creatures? The simulation explains, in detail, the important role predators play in maintaining a stable ecosystem. Through web-based research,...

Students explore the concept of interdependence. In this integrated interdependence lesson, students interpret graphs and charts that require them to analyze the relationship between Mexico and the United States. Students also...

Students study the Evolution in the Light of Fossils. Activities in this lesson range from quantitative measurements of hominoid skulls to the comparison of hominoid bone structures. They hypothesize dinosaur size and speed by looking at...

Students investigate how kidneys function. They discuss how a dialysis machine works, and conduct an experiment in which they filter different substances through a plastic window screen, various sizes of hardware cloth, and poultry...

In small groups, fourth graders identify different sources of renewable and non-renewable energy. They research the pros and cons of using each of these resources. They rank household appliances according to energy usage and efficiency....

After listening to the book, We All Go Traveling By, 1st graders discuss different modes of transportation that they see out in the world, and the environmental impacts of each one. Kids work together to create a list of the types...

Learners explore the interdependence of the animals and plants in tropical rainforests. They explore the importance of conserving biodiversity and tropical food chains. They create a tropical forest food chain and identify species that...

Young scholars explore the concept of measuring length using a one-inch pipe cleaner "inchworm." They listen to the story "Inch By Inch by Leo Lionni and discuss how the animals were measured by the inchworm in the book. In pairs...

Students brainstorm the different uses of petroleum distillates. In this chemistry instructional activity, students explain the process of fractional distillation. They analyze the impact of oil extraction to the environment.

Students relate the number and length of generations in their living family members to the number of generations that have passed since specific events in recorded history. They then apply this time conceptualization to the number of...

Learners review data from a 24-hour dietary recall to gain an understanding of the information regarding energy intake and macronutrients.

Students investigate the difference between plant and animal cells. They observe a variety o plant and animals cells by looking at a piece of cork, an onion, elodea, prepared slides of paramecium, human bone, frog blood, and human...

Students study science concepts as they are presented in poetic form. They write and present their own science poems to parents during Open House.

Students participate in mapping an actual waterway. They include reach lengths, transects, compass reading, and scale determinations. They include windfalls, plant cover, types of streambed composition, and landmarks such as trees and...

Students hypothesize dinosaur size and speed by looking at dinosaur track way or by measuring a dinosaur models water displacement. In addition, techniques to help students become familiar with the ways paleontologists study fossils can...

Middle schoolers study Newton's Third Law of Motion which involves action and reaction. They discover what makes a rocket go and then design and construct a rocket that will launch the furthest using the pressure created by an antacid...

Students construct, read and interpret tables, charts and graphs. They draw inferences and develop convincing arguments that are based on data analysis. They create a graph displaying altitude versus wind speed.

Eighth graders determine the density using mass and volume. In this science lesson, 8th graders explain why some materials float or sink. They estimate the density of objects based on whether it floats or sinks in a liquid of known...

Students research their role and develop a group position on the appropriate use of fetal tissue transplantation. They engage in role play discussion focused on the case study.

In this activity, students filter different substances through a plastic window screen, different sized hardware cloth and poultry netting. Their model shows how the thickness of a filter in the kidney is imperative in deciding what will...
