## What is a Year?

This is an activity about the motion of the Earth around the Sun. Learners will act out the motions of Earth as it orbits around the Sun over the course of one year, starting with modeling one day, then one year, and finally the months.

## Which Planet Shall We Visit?

Learners will compare images of planets and select one planet to visit and tell the tale of their visit through a comic strip. This is activity 9 of 9 in Mars and Earth: Science Learning Activities for After School.

## Hunting Icebergs: Identifying Icebergs

This self-paced, interactive tutorial guides learners through the decision-making process in locating data that will enable the identification of tabular icebergs, including: selecting the appropriate satellite orbit, and identifying the optimal solar and infrared wavelength values to discriminat

## Solar Week Friday: Learn about Solar Careers

This is a reading associated with activities during Solar Week, a twice-yearly event in March and October during which classrooms are able to interact with scientists studying the Sun. Outside of Solar Week, information, activities, and resources are archived and available online at any time.

## Exploring the Water Cycle

In this lesson, students will learn about the water cycle and how energy from the sun and the force of gravity drive this cycle. The emphasis in this lesson will be on having students understand the processes that take place in moving water through Earth’s system.

## In the News

This is an activity about challenges that humans face in future space travel as analyzed through news articles highlighting discoveries about the Sun. Learners will read and analyze a series of related articles and answer questions to determine the most newsworthy points.

## Ironing Out Curves

In this activity, students graph second and third order functions, discovering an inverse relationship between squares and square roots and between cubes and cube roots. Students graph these functions on both linear grid (evenly spaced numbers), and a log-log grid (evenly space exponents).

## Design Challenge - Shape of the Satellites

This is an activity about satellite design. Learners will create a satellite model to determine which shape will provide a steady minimum current output from solar panels, given a fixed position light source.

## Magnetic Storms and Aurora

Learners will plot and compare the amount of energy dissipated by auroras in the northern hemisphere with the recorded Kp index of magnetic storm severity.

## Space Place: What Causes the Seasons?

This article explains the role of the tilt of Earth's axis on seasonal changes. An accompanying exploration dispels the commonly held misconception that distances between the sun and Earth are a factor. The article is targeted to children ages 10-12.
