Earth didn't always have oxygen, so what caused the change that allows humans to live here? Learn about the change in O2 levels throughout geological history through an interactive graph. Each section offers greater detail on the changes...

Earth science explorers design an experiment to demonstrate that the albedo of a surface affects its temperature. They test to find out if moisture on the surface affects temperature. They discover whether or not concrete or asphalt heat...

Students research different mammals and create illustrations and narratives about them. Working individually or in small groups, students compose their rough drafts prior to creating their posters or dioramas. Students present short...

Future scientists are introduced to the chemical consequences of burning fossil fuels, learning that fossil fuel combustion leads to the formation of oxides of three nonmetals: carbon, nitrogen, and sulfur, all of which end up in the...

An overview of deforestation is the focus of this resource, which present the reader with a list of facts. Ten comprehension questions follow; learners can write their answers on a separate piece of paper. Have your environmental...

Through a fishing simulation, environmentalists discover consequences of over fishing. Afterward, they discuss how the activity relates to the impact of real-life commercial fishing. They also consider sustainability in the fishing...

Collaborative earth science groups create a working model of a watershed. Once it has been developed, you come along and introduce a change in land use, impacting the quality of water throughout their watershed. Model making is an...

Math and M&Ms® go great together when introducing a modeling activity. Allow your learners to simulate population growth and decay of fish in a pond and share their reasoning for the change in fish. With such an impact we have on our...

Here is a lesson that walks youth through an online carbon footprint calculator produced by the University of California, Berkeley. Once learners finish inputting information, they compete a worksheet with the results. This is simple,...

Polar ice samples provide scientists with valuable information about the condition of the atmosphere for hundreds of thousands of years in the past. Of particular interest is the amount of carbon dioxide in the atmosphere and its...

Elementary ecologists pretend to be migratory hummingbirds. They fly between wintering and nesting grounds, trying to reach a habitat haven. In a musical-chair fashion, some birds will miss out, and are removed from the game. To further...

Open with a discussion on weather and climate and then explain how tree rings can provide scientists with information about the earth's past climate. Pupils analyze graphics of simulated tree rings from various US locations for the...

During this game, kids become migratory shorebirds and fly among wintering, nesting, and stopover habitats. If they do not arrive at a suitable habitat on time, they do not survive. Catastrophic events are periodically introduced that...

It is recommended that you conduct this fabulous experiment as a whole-class demonstration. Collect air samples from the environment, human exhalation, and car exhaust, then compare them for carbon dioxide content using bromthymol blue...

You will need to gather a number of tokens, bags, and other various game components in order to incorporate this activity into your curriculum. Different tokens represent carbon dioxide, methane, and nitrous oxide. Printable 8.5"x11"...
