Students trace back through time to see how the nutritional value of food consumed was enhanced.  In this nutrients lesson students complete several activities that show the mass of food, and its PH value.

Eleventh graders investigate the relationship between heat and energy transfer. They review terms including heat, work, calorimetry and the procedures for an experiment. After assembling the materials for the experiment, they observe...

Students explore respiration in a lake ecosystem by experiment and research.

Students study the water quality of a stream in their area, by measuring the temperature, pH, alkalinity and conductivity. They integrate biology with earth science when using the microscope to study the living organisms in the water.

In this molecules worksheet, students calculate the mass or volume of a certain number of moles of a compound. There are 3 difficulty levels of this worksheet, each one has 6 problems to solve.

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

Pupils learn the procedure for mixing secondary colors from primary pigments and observe the results of mixing two primary colors.

Students separate a mixture of pigments with ion exchange chromatography and predict whether the ion-exchange matrix is positively or negatively charged based on the type of pigment bonded to the matrix.

Twelfth graders research physical and chemical methods used in authenticating paintings (e.g., ultraviolet fluorescence and spectroscopy, infrared spectroscopy and reflectography, X-ray diffraction, microscopy, pigment analysis, and gas...

Young scholars recognize methods used to define the mole. After converting various quantities to the mole, students provide a context for understanding the usefulness of scientific notation and the mole.

Students prepare an ad for an element, including properties and uses, in an attention getting format such as that used in the advertising business.

Students figure the number of half-lives since the sample solidified, and therefore the "age" of the sample rocks.

High schoolers assemble a classroom river model as an example of a lotic system. They control and measure biotic and abiotic information for the in-class system and compare data with a lotic system in a natural environment.

Seventh graders use a pond to explore macroinvertebrates and other organisms. They use a dichotomous key to classify the organisms and maintain a journal recording their findings.

Learners find the relationship between the variables based on experimental data. They determine mathematical relationship between pH and the amount of hydrogen Ions in solution.

Learners test samples of water to determine how a chemical water softener affects water's ability to form suds. After collecting their data and analyzing their results, students answer follow-up questions about their lab.

Students practice making graphs and interpreting them. They compare and contrast different sets of data. They use Microsoft Excel to create different types of graphs.

Students work together to research water quantity, quality and safety standards. They complete a lab to discover how to use the water from an air conditioner. They write a paper to show their findings.

Students collect and examine different soil samples. They test for specific types of soil elements and the pH level. They answer questions about optimum growing conditions as well.

Young scholars explore the differences between specific soil characteristics. They participate in an experiment in which they discover soil texture. They write their observations in a journal.

Students create a soil center on their school grounds. They begin to write in their science journals. They participate in an experiment that helps the community begin their own gardens.

Students examine how a sanitary landfill is constructed, how it functions, and how waste and leachate affects the areas around the landfill. After a discussion about landfills and leachates, students construct a Sanitary Landfill Model...

Young scholars examine insect behavior in a lab activity. Students explore the idea of chemical specificity and the reactions of termites to a chemical found in their trail pheromone. Young scholars watch a demonstration with termites...

Young scholars investigate the measurements and geometry of the school grounds. They conduct inquiry while measuring the campus and some of the city blocks. Then students draw a map to scale and categorize property types using a pie graph.
