Compare the density of different salt solutions and then observe currents that are caused by the difference. Set up a demonstration of dynamic equilibrium. The intent with these activities is to begin building understanding of density...

In this chemical reactions worksheet, students determine what is true about a system at equilibrium and give examples of macroscopic properties. Students determine minimum enthalpy and maximum entropy for reactions. This worksheet has 2...

Henri-Louis Le Chatelier wrote many papers throughout his 85-year life, but he is remembered for one of his earliest discoveries, now known as Le Chatelier's Principle. The final lesson in an 11-part series encourages young chemists to...

Students explore the basics of ecology through numerous hands-on and relevant activities. They participate in an online food chain demonstration, which explores food web dynamics. They dissect owl pellets, examine the prey's bones, and...

Students identify and separate the different zones of the beach by observation. They investigate beach zonation by gathering and comparing sand samples gathered from different areas of the beach.

Several graphs help to illustrate the dynamics of international trade in this slideshow. World prices, imports and exports, and the economic impact of tariffs are detailed in the presentation, along with arguments for free trade and the...

There's no need to have friction among instructors regarding the resource. Pupils investigate how marbles and coins slide along different surfaces which gives them information to estimate coefficients of friction.

Tenth graders are introduced to the process of succession and gain awareness of the changing nature of ecosystems. They demonstrate a comprehension of the dynamic nature of ecosystems, including the relationship between ecological...

Introduce your class to various reptiles and amphibians. They will meet and identify a representative from each of the four major reptile families, then learn about and discuss reptile characteristics. Next, they will identify and...

What can your class learn from a skull? With proper facilitation, they can learn about diet, physical adaptations, special differences, and even the environment. Pupils will examine a series of mammal skulls and pelts to help them...

What a terrific instructional activity! Learners discuss the animal kingdom, and classify them as vertebrates and invertebrates. They also identify them as fish, amphibians, reptiles, birds, and mammals. There is even a taxonomic...

Have your class learn about marine life through this resource. This comprehensive lesson has learners discuss marine life, learn key vocabulary, discuss environmental concerns, and play games related to migration and predator/prey...

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...

What a terrific way to explore the pond habitat! Learners discuss the animal and plant life found in the Long Island area. They also discuss vocabulary terms, identify pollution concerns, and resource conservation.

The class will examine a series of live or stuffed animals in order to learn how different animals survive in distinctive habitats. As they examine each animal, they will be asked a series of critical thinking questions geared at getting...

Focusing on the wildlife in their area, learners identify endangered and threatened species and what these animals need to survive. While this lesson involves animals in the Long Island area, it could be adapted for use with any area.

Your class will love exploring animal conservation through this lesson on bats. Learners discuss the importance of bats in the ecosystem and talk about the different types and their characteristics. As a follow up, a model of a bat or a...

Discuss the importance of wildlife conservation. Learners talk about the animals and plants on the US Fish and Wildlife Services list of endangered and threatened species. Then, they engage in a detailed discussion of the reasons these...

Young scholars investigate the characteristics of the beach environment and explore beach zonation. After gathering samples from different areas of the beach, students discuss how the beaches work and the characteristic of each zone....

Students study the concepts of polymerization and the function of crosslinkage.  In this polymer lesson students complete a lab activity and write down their observations. 

The final lesson in a two-part series prompts scholars to create newspaper articles and succession events. Applying their knowledge of the ecosystem and the past examples of succession, they predict what will happen in the future...

Introduce ecology classes to biodiversity and interdependence in ecosystems with a PowerPoint presentation. Then, they get up-close and personal with the invertebrate world by collecting insects, classifying them, and graphing their...

Climate models mathematically represent the interactions of the atmosphere, oceans, land, sun, surface, and ice. Part two in the series of four lessons looks at the role greenhouse gases play in keeping Earth warm and has participants...

Students explore the sustainability of our environment, the trend in rising temperatures and the emission of greenhouse cases. Using given data, students test and construct a confidence interval and the difference between two population...
