## Introduction and Chapter 1

This is the first chapter of Meteorology: An Educator's Resource for Inquiry-based Learning, Grades 5-9.

## Exploring Magnetic Fields

This is an activity about magnetic fields. Using iron filings, learners will observe magnets in various arrangements to investigate the magnetic field lines of force. This information is then related to magnetic loops on the Sun's surface and the magnetic field of the Earth.

This is an activity about the magnetic fields of the Sun and Earth, and the interplanetary magnetic field, or IMF.

## NGC 2174: Pillars in the Monkey Head Nebula lithograph and In Search of ... Star Formation classroom activity

This two-page lithograph features an infrared image entitled, Pillars in the Monkey Head Nebula (the nebula also known as NGC 2174), located in the Orion constellation.

## Climate Kids: Earthy Word Games

This site contains four word find puzzles; one on each of the following topics: air, water, land and life. In addition, the site features information on an Ecosphere - a self-contained living world inside a closed glass container.

## Model the Sun and Earth

Learners will make scale models of the Sun and Earth out of paper mache. This activity is from the DIY Sun Science app and is for ages 10 and up.

## Thermo and Fluid Dynamics of a Homemade Lava Lamp

In this experiment, students create a "lava lamp" - a beaker on a hotplate, and investigate buoyancy, convection and other fluid and thermodynamic properties using ink, water, vegetable oil and Alka-Seltzer tablets.

## No Strings Calculator

In this activity students develop a simplified log table using information from their Log Tapes. Then they use it to solve arithmetic problems by looking up and combining logs, and finding the antilog.

## Neutron Stars in the News

In this science literacy extension students read and analyze two different articles about XMM-Newton discoveries involving neutron stars and their magnetic fields. This is Activity 4 of the Supernova Guide developed by the XMM-Newton and GLAST E/PO programs.

## Parts per Thousand

In this problem set, learners will calculate the parts-per-thousand measure for different scenarios, including ocean salinity as depicted in the image included. Answer key is provided. This is part of Earth Math: A Brief Mathematical Guide to Earth Science and Climate Change.
