In this special senses worksheet, 9th graders briefly describe the structure of a taste bud and the pathway a signal takes to the brain. Then they list the five basic taste sensations and homeostatic values of taste. Students also...

Young scholars investigate how glaciers flow through valleys. They answer discussion questions, and in small groups create a simulation of a glacier using a plastic shoe box, water, cornstarch, and pebbles, evaluating their results on a...

Learners are introduced to the concepts of supply and demand. Using the Law of Demand and Supply, they develop charts and graphic models of supply and demand. They compare and contrast the behavior of consumers and suppliers when there...

Students participate in a demonstration in which they role-play polar bears and habitat components to demonstrate the impacts of climate change on the Arctic Ocean ecosystem.

Students describe how diffusion occurs within a liquid. They explain a situation where diffusion through a liquid might occur in the natural world.

Pupils make predictions about the global temperature of the earth and to see how this is dependent upon a number of variables. Students visualize how changing parameters can impact the global temperature of the earth.

Students examine their own environments and make connections to larger ecosystems. They watch a video about the gulf of Maine and record the changes that have occurred. They research the gulf and create a food web.

Students experiment to understand the basic concept of polymerization and to understand the dissolution theory. Student experiment with polymers to understand its behavior and the mechanical behavior of polymer networks.

Students examine the problem concerning the evolution of seed color in pinto bean plants "How does natural selection change the frequency of genes or traits over many generations"? Students work in teams to design an experiment that...

High schoolers explore solubility of gases in water, Henry's Law, LeChatelier's Principal, and supersaturation of gases in water.

Students work together in groups to participate in a trading game. They are allowed to trade with different people in each round. They discover free and restricted trade.

This lesson plan begins with a PowerPoint slideshow that covers important ecological concepts about biomes, limiting factors, carrying capacity, and population growth. Students will look at the population dynamics involved with the...

This is a biology or environmental science instructional activity that incorporates technology. This project-based plan is designed to be used as students study the factors that affect the dynamic equilibrium of populations and...

This site from the Illinois Institute of Technology provides a lab activity in which learners determine the location of the center of mass of an irregularly shaped object. Observations are related to the balancing point of the object....

This Illinois Institute of Technologysite provides a lab activity in which young scholars find the center of gravity of a box which has nonuniform weight distribution. Complete with directions and discussion questions; answers provided.
