Potential Hazards in Your Home

Chemistry whizzes test the change in water temperature produced by a burning candle and the change in acid temperature produced by magnesium metal. With these two laboratory activities they explore heat produced during chemical...

Not all chemical reactions happen at the same rate because some, like explosions, occur quickly and some, like rusting, occur over time. Here, learners explore chemical reactions and their rates in the 16th lesson of 36. Through readings...

Biotechnology pros produce their own biofuel using waste oil and fresh vegetable oil. They test the quality of their product using titration techniques and pH analysis. They write their observations and report their findings. Be aware...

Two versions of this handout are provided, the second with more detailed information on the same topics. Chemistry aces survey chemical reactions, heat energy transferred, and the action of enzymes by reading this resource. You can...

Beginning Boyles and curious Curies can safely experiment with the virtual mixing of elements using this entertaining application. 

The scientific explanation of seismic waves is detailed in the introduction. A fictional scenario is also provided for your class to discuss. Pictures and handouts that are meant to be included, however, they are not accessible....

Scientists can't observe bonds breaking or forming, so how do they distinguish between exothermic and endothermic reactions? Young scholars complete two experiments to do just that. They monitor temperature change and calculate the...

Students examine how hazardous wastes are cleaned up. They work together to identify the positives and negatives of cleaning up certain hazardous wastes. They answer questions as part of the activity.

Students examine the relationship between hazardous substances and hazardous waste. They identify toxic chemicals and how they are disposed of. They work together to answer questions about how they are improperly used.

Young scholars work together to role play a situation which shows the decision-making process in cleaning up hazardous waste. They identify participates in the Superfund and make judgments about how cleanup would help an area. They...
