Science 8

Explore the wonderful world of waves! Even observe a string vibrate in slow motion. Wiggle the end of the string and make waves, or adjust the frequency and amplitude of an oscillator.

Experiment with an electronics kit! Build circuits with batteries, resistors, light bulbs, and switches. Determine if everyday objects are conductors or insulators, and take measurements with an ammeter and voltmeter. View the circuit as a schematic diagram, or switch to a lifelike view.

Create a custom object to explore the effects of mass and volume ...

Density lab is a complete simulation of a classic physical science density lab.

Test the pH of everyday liquids such as coffee, spit, and soap to ...

m. States of Matter States Phase Changes Interaction .

The difference between a physical reaction and a chemical reaction is composition. In a chemical reaction, there is a change in the composition of the substances in question; in a physical change there is a difference in the appearance, smell, or simple display of a sample of matter without a change in composition.

Explore the movement of gases, liquids and solids at a molecular level, and investigate how temperature and intermolecular attractions affect phase changes.
