Students summarize and illustrate how a water treatment plant and wastewater treatment plant work. Students describe the source of water for their community and the adequacy of groundwater to meet the community's needs. Students also...

Students consider the adaptation of life forms through natural selection to fill various niches and accommodate changing environmental conditions. They select an ecosystem and conduct research to provide as much detailed information as...

In this stoichiometry worksheet, students calculate theoretical yield and percent yield. This worksheet has 2 problems to solve.

Students name the factors (concentration, temperature, and a catalyst) which can affect the rate of a chemical reaction. They use their knowledge of particle theory to explain their observations. Pupils comprehend that the...

Students see that chemistry is the study of matter, how matter reacts and combines to create new chemicals, the changes that take place in matter and what makes up matter. This lesson provides many good ideas across the curriculum to...

Tenth graders distinguish between chemical and physical properties and changes in matter when given specific examples. They view a video of sports activities. Students chose their favorite sport and design an experiment to improve sports...

Learners complete a unit on the chemical and technological processes of food preparation. They observe various experiments, describe changes in materials through cooking, identify safety and hygiene issues, and cook various recipes.

Students observe and record what occurs when yeast is added to hydrogen peroxide. They indicate why a chemical reaction (decompostion) must have occurred during the experiement. Pupils explain why yeast was used. Students comprehend the...

Learners chemically test water, observe microscopic organisms in the classroom, and screen the sample for macroinvertebrates. They design a reporting sheet that list all the items to be tested and a space to record the results.

Pupils perform an experiment which will illustrate how to measure the approximate pH of chemicals in water using a pH indicator. They understand that a pH indicator is a chemical that changes color when it comes in contact with acids or...

Pupils test for amaylase enzyme in a variety of substances. Student pairs perform a series of tests to determine how long it takes the starch sample to change to sugar molecules and the blue color to disappear when various saliva samples...

Students describe characteristics and common uses of acids and bases. They describe the role of natural indicators in the chemistry of acids and bases after testing and making observations on a variety of plant extracts. Students observe...

Eighth graders measure temperature changes and make drawings of the interactions between matter and energy. By measuring the temperature students can conclude if there are changes in levels of energy. .

Seventh graders become more familiar with how our food is broken down mechanically and chemically. They also trace the food through the alimentary canal.

Students compare the weathering of materials. in this weathering lesson, students experiment with the chemical and physical weathering of different materials. Students use salt and water as an example of how weathering occurs.

Learners explain how equilibrium quantities are changed by temperature, pressure or different concentration of substances. They work together to complete equilibrium equations. They identify the relationship between absorption of light...

In this chemical equilibrium worksheet, students review Le Chatelier's Principle and predict the direction of equilibrium shift for different changes to a chemical reactions. Students also review enthalpy and entropy. This worksheet has...

Fourth graders study physical and chemical weathering. They explain how the processes of weathering and erosion change and move materials that become soil. They create a K-W-L chart to show what they know and list what else they would...

In this thermochemistry instructional activity, students calculate the enthalpy of vaporization as well as the write the thermochemical expression for the production of the chemical reaction.

Learners locate the ozone layer of the atmosphere. They explain natural formation of ozone. They list chemicals that react with ozone. They explain how CFC's destroy ozone.

Tenth graders evaluate the physical mechanisms that cause a change in NOx emissions. In this combustion lesson, 10th graders participate in a research project. Students create a presentation of their findings. 

In this bellwork worksheet, students answer questions about chemical and mechanical weathering, particle size, and the soil profile at the start of class.

Students investigate why green leaves change colors in the fall. They press leaves and write a poem, create a chlorophyll leaf print, take a nature walk, and create a leaf shape poster.

Young scholars design posters on the ozone to be judged. They design a board game on the depletion of the ozone and list the layers of the atmosphere. They construct a collage of the atmosphere into layers according to the way...
