Explore what makes a reaction happen by colliding atoms and molecules. Design experiments with different reactions, concentrations, and temperatures. When are reactions reversible? What affects the rate of a reaction?
Video explores how to compare a rate given in an equation to a rate shown on a graph. [1:24]
Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.

The CyberSquad works with area to figure out how to power a skate park using solar panels in this interactive from WNET. In the accompanying classroom activity, students view and analyze a series of video clips from Cyberchase and complete an activity using area and ratio. Students take what they've learned and put it to the test by designing their own solar power dream house.
In this lesson the students will be reviewing for their assessment on rates and unit rates using a fun game.
This U.S. Census Bureau Web site has two population clocks with notes available. One clock shows the population increase for the United States. The other shows the world population increase.
The students will get the opportunity to work in stations to reinforce and deepen their understanding of rates and unit rates.
Student centered activities based on rates and unit rates!
Find a quick, concise explanation of rates and ratios. Examples are given and clearly explained.
