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...

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 the role that...

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. 

How does water pollution affect the organisms living in the water? Use three science experiments to examine how erosion and other pollutants can affect water quality. Each experiment focuses on a different aspect of pollution and...

Students explore what a food web is. For 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, piscivore, or...

Learners 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.

Young scholars 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...

Students explore nutrient, bacterial, and toxic surface water pollution. They identify the amount of water they use each day and summarize the kinds of substances that cause water pollution. They predict what will happen in water...
