The best part of learning about equilibrium is that nothing changes. Young chemists observe four demonstrations during this lesson: equilibrium in a saturated solution, equilibrium with an acid-base indicator, equilibrium with cobalt...

In this solubility worksheet, students identify substances as either ionic or molecular, define saturated solution and solubility, and calculate concentration of solutions. This worksheet has 7 short answer, 5 fill in the blank, and 27...

Students use a sponge and water model to explore the concept of relative humidity and create a percent scale. They define humidity and saturation, build a simple humidity/saturation model, collect, predict and interpret data, and create...

Students determine the solubility product constant and the concentration of a hydroxide. For this solubility product lesson plan, students use a solution of calcium hydroxide to neutralize a known concentration of hydrochloric acid. They...

It doesn't have to be Easter to enjoy this egg-stra fun art project. Kids crunch egg shells, saturate them with color, and glue them to boxes or other objects to make egg-stra special gifts.

High schoolers relate solution concentration and saturation to color and compare methods of changing value and color intensity with paint solutions.

Students calculate the concentration of different solutions. In this chemistry instructional activity, students explain what a solution is. They explain ways to change the concentration of a solution.

Eighth graders examine different solutions.  In this solution material instructional activity students complete a lab activity and several worksheets. 

Students examine the energy dependence of active transport as well as te properties of specificity, competition, saturation, and inhibition. They anesthetize an insect and inject saline into the abdomen.

Students obseve and compare molecular movement within water at various temperatures and of varying salinity. They discuss the movement of water on a larger scale which can affect the movement and concentrations of microbial populations...

Ninth graders investigate relationship between the temperature and concentration of dissolved oxygen in water. They examine how pollution and other natural influences can cause the parameters to change. In groups, 9th graders collect...

After brainstorming what they know about ocean acidification, youngsters place eggs in acid to determine the effects on calcium-containing organisms, and add carbon dioxide to solutions with sea shell material to discover the impact on...

The sun provides the link between this art and science activity. Kids use sunlight (or light from an artificial source) to produce heliographic prints on fabric or paper.

How can organisms light up in water? Bioluminescence is light produced in a chemical reaction that can occur in an organism's body. First, learners determine what happens to light/color as you move into the deep ocean. In groups, they...

Students observe an electrolytic titration using a conductivity tester. In this titration lesson, students observe a solution of acid conducting electricity using the conductivity apparatus. They observe the acid solution being titrated...

Students identify the different types of mixtures. They identify examples of solutions, suspensions, colloidal dispersions, and emulsions through a game and basic experiments.

Students examine the abstract art of Helen Frankenthaler. For this art analysis lesson, students complete a criticism of the aesthetics of the art, analyze the color use in the art, and research the history of abstract art.

High schoolers conduct an experiment to determine a fly's ability to detect sugar, its behavioral response, how a previous experience may alter the response, if a fly can be tricked, and how human sensitivity compares to a fly.

Eighth graders examine the difference between confining layers and aquifers in a basic water table aquifer scenario. They contour groundwater elevation and petroleum product thickness data.

Students study how a geologist examines a hazardous waste spill using an actual site. They use site data to map the spill, find its source and determine how fast the spill is spreading.

High schoolers examine the concepts of light and chlorophyll. They participate in an experiment in which the chlorophyll shows as a red ring on the test tube. They answer discussion questions to end the lesson.

Through these lesson plans, students explore and discuss the role of dietary fat as an important energy source. In addition to providing detailed instructions for teachers, this website includes all the handouts and charts needed to...
