NASA CONNECT Squeak Web Activities

Before you can enter the exciting world of Squeak Etoys, you need to download the Squeak plugin at squeakland.org. Once you have the Squeak plug-in installed, you can access any Etoys project from an internet browser like Netscape, Firefox, Opera, Safari, or IE. Etoys in Squeak is a free, exciting, multimedia, object-oriented, authoring environment that runs on sevral different computer platforms. Playing in the Squeak Etoy environment is mind challenging. Explore and create as you have fun with Squeak Etoy projects. Click on any project below to start. Sound is a part of the multimedia environment so be sure your speaker is turned on. Visit NASA CONNECT to get supporting information for the programs listed in italics at the bottom of each description.

	Northern Lights Challenge: Answer the question "Do Northern Lights exist on other planets?" Exploration tools in the Squeak project are waiting for you to explore the other planets. Dancing in the Night Sky	Concepts: Electromagnetism, electrons, and atmosphere. Math: Data analysis, ratio, and proportion.
	Rocket Launch Challenge: Launch rockets and learn about motion and gravity. Take and plot data to better understand position, velocity and acceleration. Try your rocket on the Moon and other planets. Festival of Flight	Concepts: Position, velocity, acceleration, and gravity. Math: Plotting and data analysis.
	Robot Challenge 1: Design a Norbot or Zotbot to complete a mission on the International Spaced Station. Learn the relation between geometric figures as you assemble the needed parts into the Norbot or Zotbot. PSA: The Astronaut Helper	Concepts: Reading comprehension, design and analysis. Math: Relations among geometric figures.
	Robot Challenge 2: Design a Norbot or Zotbot to complete a mission on the International Spaced Station. Learn the relation between geometric figures as you assemble the needed parts into the Norbot or Zotbot. PSA: The Astronaut Helper	Concepts: Reading comprehension, design and analysis. Math: Relations among geometric figures.
	Extrasolar Challenge: Norbert and Zot need help to make a model of Norbania. They are homesick. Learn about the relation between the distance of the planet from its sun and its period of revolution. The Venus Transit	Concepts: Motion, solar system, Astronomical Unit, period. Math: Plotting, data analysis and ratios.
	Laser Challenge: Help Norbert and Zot calibrate their laser system and measure thicknesses of aerosols and clouds. Learn how the laser light intensity decreases as it passes through aerosols and clouds. The "A" Train Express	Concepts: Lasers, calibration and measurement. Math: Plotting, data analysis, ratios and algebra.
	Graph Challenge:You are trying to break barriers and design the fastest balloon X-1 aircraft. Can you gather, plot and analyze data to help you in the Breaking Barriers in-class activity? Breaking Barriers: Solving Linear Equations	Concepts: Flight, speed, length, time. Math: Plotting, length, angle, area, measurement, data analysis.
