Science 20 Interactive Media Science 20 contains learning resources that address topics from the senior high school science curriculum: Chemical Changes; Changes in Motion; The Changing Earth; and Changes in Living Systems. The resource includes interactive Gizmos licensed from ExploreLearning.

The new Science 20 textbook includes a student CD that contains multimedia segments, handouts, suggested answers and Distance Learning Student Guides. This CD will be installed in the ICT Data folder of the server in your high school. By using the multimedia segments and activities, students will achieve many ICT outcomes for Science 20.

Unit A: Chemical Changes

1. Students will: investigate aqueous solutions to determine conductivity and to calculate concentration.
Physical Properties of Matter This resource explores some of the properties of matter by providing students with two pieces of unknown metal-based substances. The goal is to identify the composition of these substances through experimentation and assessment of information about conductivity, density, hardness, magnetism, and melting point.  
Ionic and Molecular Compounds
 This resource allows students to explore the differences between ionic and molecular compounds in "show" and "explore" modes. In the "show" mode, students observe the differences in composition and properties of ionic and molecular compounds; they also learn how experiments on solubility and conductivity can help determine these differences. In the "explore" mode, students are provided with an opportunity to apply what they have learned by formulating conclusions on whether four compounds are either ionic or molecular. Their conclusions are based on an examination of the periodic table; experiments of solubility and conductivity; and observation of the state of matter.

In Motion for Thrills
 Amusement parks are the best places to go for fun and excitement. They are the most unique places to study motion. Motion is the change of position of a body in space as time passes. This project will involve you and your partners to apply the laws of motion while designing an amusement park ride that is both thrilling and safe.

Kepler's First Law
 Kepler's first law of undisturbed planetary motion: The orbit of each planet is an ellipse and the Sun is at one focus. This applet demonstrates this law. 
Kepler's Second Law
 Kepler's second law of the undisturbed planetary motion: The line joining the planet to the Sun sweeps out equal areas in equal intervals of time. This law shall be illustrated by a computer simulation. 
Air Track
 This activity models a basic air track with two blocks. You can change the coefficient of restitution, initial masses, and velocities. 
Elastic and Inelastic Collisions
 This Java applet deals with the extreme cases of a collision process illustrated by two wagons: For an elastic collision it is characteristic that the sum of the kinetic energies of the involved bodies is constant. 

2-D Collisions
 This activity lets you deal with 2D elastic/inelastic collisions on a flat (or tilted) table and even use magnetic pucks!

Unit C: The Changing Earth

1. Students will: analyze the scientific evidence and explanations for geologic phenomena that occurred long ago or are taking place over a long period of time.
