This module introduces the concept of biological absorption, storage and distribution of chemicals.

This module provides an intrioduction to acid and base chemistry. The Arrhenius and Bronsted-Lowry concepts of acids and bases are discussed as well as the pH scale and neutralization reactions.

In this activity, students examine a photograph of the night sky and answer questions about their observations. The picture, taken by a high school student in upstate New York, offers insight into the Earth's rotation, apparent star motion, the location of Polaris (the North Star), circumpolar constellations, and pointer stars.

Students will complete this survey that determines their personal and household contributions to atmospheric Carbon dioxide by using information about their previous year's consumption. They will understand that Carbon dioxide is a greenhouse gas produced by the combustion of fossil fuels, and that its production can be minimized by taking personal steps to conserve.

This lesson introduces J. J. Thomson's discovery of the electron and E. Rutherford's planetary model of atomic structure. This is the first in a series covering modern atomic theory.

Located near Townsville, North Queensland, AIMS researchers collect and analyze data to improve our understanding of the marine world, and to find science-based management practices that ensure long-term sustainable use and development of marine resources. Site features information on facilities, faculty, current projects, open house and other events, and employment opportunities. Also features the Mariner's Journal, a log from several AIMS research cruises.

This module provides information on the content and writing style used in writing a Visionlearning teaching module.

This activity consists of two parts in which students investigate heat transfer by radiation and by conduction. In the first part, students design and conduct an experiment to test the effect of color on an object's ability to radiate energy (heat). In the second part, they investigate the transfer of energy from a hotter object to a cooler one, in this case, containers of hot and cold water. In both experiments, they are required to state a hypothesis, make a list of materials and procedures needed for the experiment, collect and graph data, and state a conclusion. Each experiment is accompanied by a set of analysis and conclusion questions.

The purpose of this resource is to measure and classify the plant life at a Land Cover Site to help determine the MUC classification.

In this demonstration, the teacher will use a potato and hydrogen peroxide to generate oxygen in a closed environment. Students can then observe its effects on a burning wooden splint and on burning steel wool. They will understand that a large amount of energy can be released by the process of oxidation. As an extension, the teacher can discuss how the appearance of oxygen (produced by cyanobacteria) in Earth's early atmosphere initially resulted in the formation of large deposits of iron oxide (Banded Iron Formations) and then aided in the evolution of more complex life forms.

This module provides an introduction to the concept of carbohydrates as a macronutrient. The biochemical structure of simple sugars and complex carbohydrates are compared and contrasted.

This module provides an overview of the biogeochemical carbon cycle. Major sources and sinks of carbon are discussed as well as the impact of human activities on global carbon levels.

This lesson introduces the cell as the basic structural unit of life, and details modern cell theory.

This is the second in a series of modules which detail the research of Charles Darwin and evolutionary theory. This module continues with a discussion of the processes that led to Darwin's formulation of the theory of natural selection.

This module introduces Darwin's Galapagos travels and an introduction to the theory of evolution as a force for biological change and diversification. This is the first in a series of modules which detail the research of Charles Darwin and evolutionary theory.

It discusses the process of equation writing and balancing chemical equations in perspective of the chemical changes that take place during a reaction. This module is the third in a series on chemical reactions.

It introduces the concept of electron exchange and briefly explains exothermic and endothermic reactions. This is the first in a series of modules on chemical reactions.

Climographs, graphic plots of monthly temperature and precipitation, allow students to see how differences in insolation at various locations affect rates of heating and cooling. In this activity, students use climographs to plot locations using latitude and longitude, calculate annual temperature ranges, and relate unequal rates of heating and cooling to climate variations. They will also construct climographs for two locations in New York, analyze them, and answer questions about their observations.

The purpose of the resource is to produce a land cover type map from the digital file of a Landsat satellite image using MultiSpec software.

The purpose of this activity is to construct a model that will provide students with a visual representation of parts per billion. Students work in teams to construct cubes of different volumes and to compare them to get a feel for parts per million by volume and parts per billion by volume. The intended outcome is that students gain a feeling for the small quantities of gases, such as ozone, present in the Earth's atmosphere.
