Students identify diffusion and its processes through experimentation and calculations. They also use a CBL and conductivity probe to measure the conductivity of various solutions and study the effect of concentration gradients on the...

Three experiments involving pennies help young chemists see the chemical reactions between copper and other elements. The first experiment is rhetorical (it prompts students to leave a bright penny out for a year) but the second two...

Students pretend they are water droplets traveling through the water cycle. Using their text, they discover the steps in the cycle and the different paths water can take. They write a report about their journey through the water cycle...

Young scholars graph dissolved oxygen versus depth using data taken from NECOP Program. In this marine science activity, students explain the causes of hypoxia. They recommend possible solutions to this problem.

Student explore factors affecting ecosystems. They test local water samples for pH level. After creating a methodology for data collection, they collect data, compare results, and draw conclusions based upon results.

Students examine the effects of detergents and fertilizers on aquatic life and describe algae. Students define the term eutrophication as the process by which a body of water, such as a pond, lake, stream, or river, has a sudden increase...

Fifth graders use the dots to simulate water pollutants in a lake. They use cups to collect a sample of "water." Students sort the dots by color and record the number of each dot color under the correct pollutant name in the Lake Water...

Students study bogs. They tour, collect physical, chemical, and biological data and analyze a pristine bog community. Using the data, they draw a map and a cross section of the bog.

Young scholars study the ecology, habitats, geographic range and feeding habits of narwhals. They determine at least three reasons for the decline in the narwhal populations and complete the accompanying worksheets.

Middle schoolers investigate how climate changes affect top predators in Arctic marine ecosystems. Students complete a worksheet and write a report based on their responses to a scientific paper.

Students map and calculate the area of the school parking lot and then the volume of water falling on the school parking lot. They map the route surface runoff will take to the nearest water body and describe the roles that human...

Students list and describe three types of surface water pollutants. They observe the effects of various water pollutants on algae growth. Three causes of each surface water pollutant is listed.

Learners investigate the physical, chemical and biological parameters necessary to establish an ecological baseline. Establishing an ecological baseline not only shows the ecological characteristics of a creek but makes the possible...

Observe two different water samples and write down observations. Write a paragraph which predicts the relative amounts of nutrients, nitrates, and phosphates in the water samples. Compare water samples under a microscope.

Students list conditions necessary for humans to survive. They then mix yeast with a nutrient broth consisting of warm water and table sugar in a plastic bottle, capping it with a party balloon and compare the factors within the bottle...

Students test water for its quality and record their information.In this water quality lesson plan, students investigate water for pH, macro invertebrates and identify its characteristics. Students complete worksheets on their data for...

Students collect water samples from local freshwater sources and test for pH, dissolved oxygen, nitrates, macroinvertebrates, phosphates, and coliform bacteria in order to determine water quality for each source.

For this biology worksheet, students examine the transport of gases in the circulatory system and how they bond to hemoglobin.

In this water and solvent learning exercise, students answer 20 questions about solutes, solvents, polarity in molecules, and the characteristics of water as a solvent. Students answer 3 questions about the lab they completed using...

Students observe the production of gas as an effect of photosynthesis. In this biology instructional activity, students perform an experiment with pondweed and make measurements and predictions about photosynthesis and the plant.

In this elements worksheet, students use the relative atomic masses of given elements to calculate the relative formula mass. Students calculate the mass of compounds from given number of moles and determine the number of moles from a...

Students discuss metabolism. In this metabolism lesson plan, students evaluate evidence form a research report and discuss the basis for hypothetical metabolic adaptations to low-oxygen environments in the anchialine caves.

In this chemical and physical change worksheet, learners are given details about chemical and physical changes. They are given 2 examples using water and salt and they identify 15 statements as chemical or physical changes. Students...

In this worksheet for making standard solutions, learners read about making a standard solution and perform the three background calculations necessary to make one. Students then make a solution by weighing a given substance, adding it...
