In this identifying the definitions of micro-organisms worksheet, students match the correct key words with the correct definitions. Students match 8 answers.

Ecology candidates culture pond water organisms over a few days time, then they experiment to find out how increasing nutrients affects the population. As part of a unit on water, this exploration gives your class an understanding of how...

Livestock managers reinforce math and science skills while learning about the nutrients found in manure. They predict which animal produces the largest amount and which animal's manure contains the most nitrogen. Finally, they compare...

Act out the circulation of blood in the body with an innovative activity. Kids act as either body parts or blood, and carry necessary nutrients and waste throughout different stations to represent the way that oxygen circulates. 

Many different kinds of organisms live in water. Excess nutrients can cause over-abundant growth of some organisms living in water and non-point source pollution is a major threat to water supplies in the United States. In this lesson...

Young scientists roll up their sleeves and get a little dirty in this three-day earth science investigation. Following the scientific method, children monitor the growth of algae in pond water samples in order to determine...

Students explore what a food web is. In this science lesson, students examine how nutrients and other pollutants enter a lake and play a food web game whereby students pretend they are either zooplankton, planktivore,...

Students research organisms that live in the Chesapeake Bay ecosystem. In this science lesson, students choose an organism and research how it is affected by humans. Students create a presentation of their findings.

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

Students discuss concept and specificity of habitats, both marine and terrestrial, list similarities and differences in the habitats of a kelp forest and a terrestrial forest, compare types of organisms that occupy corresponding types of...
