Super scientists tests the toxicity of water using radish seed bioassays. Over the course of five days, scholars observe the germination process of several radish seeds, looking closely at their roots to determine the level of toxins...

Students measure the toxic levels of runoff and discuss the effects it would have on the aquatic system. In this runoff lesson plan, students answer questions to how runoff would affect the animals in an aquatic system.

Students explore ways to use indicators to distinguish between acids and bases. They conduct an experiment to model and discuss the harmful effect of acid rain in our living and non-living environment.

Students determine how evidence gained from a simulated test for the presence of pesticide residues can be used to determine risk. They use peas to simulate pesticide residue testing.

Organization is key in essay writing. The two organizational charts included in this resource model the block approach and the point-by-point approach to organizing a compare and contrast style essay. After examining the...

High schoolers observe beakers of water that contain different amounts of a mystery chemical. They discuss how each amount of the chemical might affect them if the chemical was beneficial or harmful to their bodies.

Fifth graders, in groups, conduct an experiment in which they measure ground level ozone levels using an ozone measuring kit. They analyze and compare the weather conditions and locations where ozone readings are highest and lowest.

Learners observe the effects of acid rain on plants through experimentation and research. Students research types of crops in their area. Learners work in small groups to complete the experiments given, as well as write a report and...

Drugs can both help and harm depending on how they are used. Fifth graders complete a worksheet that provides background information on prescription drugs. They read the text and then describe why medication manufacturers label pill...
