## A Simple Model for Atmospheric Carbon Dioxide

In this problem set, learners will create and use a differential equation of rate-of-change of atmospheric carbon dioxide.

## Super Star Meets the Plucky Planet... Or, how Earth and Sun come to mutual understanding and respect

This is an animated and narrated storybook about the Sun and its effects on Earth. Learners will read or hear about characteristics of the Sun and Earth that influence their interaction.

## Solar Convection

Learners will use hot and cold water to see how fluids at different temperature move around in convection currents. This activity is from the DIY Sun Science app and is for ages 10 and up.

## Severe Weather: Hurricanes!

In this problem-based learning activity, students will study the action of a previous hurricane (Hurricane Andrew, 1992) in preparation for analyzing, tracking, and predicting landfall of the next hurricane to hit the United States during the school year.

## Looking Back in Time

This lesson plan will provide a concrete way for students to understand the concept of distance in space equals distance in time. This is done using information gathered from a timeline activity in Lesson 1: Earth, the Universe, and Culture.

## Temperature vs. Carbon Dioxide

Students examine graphical and tabular data to determine whether the evidence suggests that becomes CO² concentrations and temperature rise can be linked causally. The resource provides graphs and tabular data for student investigation and a student worksheet.

## Sand or Rock: Finding Out from 1000 km

Learners will measure temperature of two different surfaces; sand and stone; on a sunny day, make a series of temperature measurements, and plot the results. Extensions include experimenting with different materials, using temperature sensors and noncontact infrared thermometers.

## How Do We Get There?

This is a lesson/briefing about the Dawn mission and the significance of its ion propulsion system.

## Plates on the Move

In this activity, students create a model of sea floor spreading using two sheets of white paper and a metric ruler. The paper strips are pulled through a slit representing a mid-ocean ridge and divergent plate boundary.

## Exploring Relationships Among Variables in a Particular Month

In this activity, student teams explore the connections between parts of the Earth system by examining a time series of environmental data maps.
