If the majority of our planet is covered with water, why do we need to bother conserving it? With a thorough and varied investigation into the location and types of water on the earth, learners will gain an understanding of why this...

Rocks can bend? Pupils investigate how heat and pressure produce metamorphic rocks by modeling them using clay, and then categorize samples based on observable characteristics. The lesson ends with a metamorphic rock identification...

Young scholars investigate various substances to determine the perpetrator of a crime. In this biology lesson, students test for the presence of organic compounds in various samples. They identify an unknown substance based on its...

Sixth graders describe the physical and chemical properties of acids. In this chemistry lesson, 6th graders test the acidity of different solutions. They identify acids and bases using the pH scale.

Students use GPS and trees to explore lichens and air quality.

High schoolers 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...

Eighth graders study the concepts of acids, bases, salts and neutralization. They discuss steam adoption program, acid rain and other ecological implications. They use indicators to obtain pH values of household chemicals and to...

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...

Middle schoolers explore chemical solutions. For this chemistry lesson, students investigate the relationship between three related experiments about solutions. Middle schoolers determine variables that affect the chemical concentration...

Eighth graders discuss uses and disposal of common household chemicals. They select a household chemical to test for impact on plant germination. Students decide how they want to set up a seed germination project. They design their plan,...

Students evaluate water quality of different sources.  In this water assessment lesson students chemical testing, identify biological factors in the stream, and write a paper on their position of the stream's quality. 

In this chemistry review worksheet, students give atomic symbols for given atoms, calculate moles, determine empirical formulas, and balance chemical equations. This worksheet has 1 drawing, 9 fill in the blank, and 12 word problems.

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.

Students discuss the physical and chemical properties of metals and non-metals. As a group, they classify items as a metal or non-metal. Using the periodic table chart, students discuss the characteristics of each metal. Based upon...

For this chemical compounds worksheet, students calculate moles, molar concentration, and volume of given compounds. Students balance equations, give the formula and charge of polyatomic ions, and draw Lewis electron dot structures. This...

Students explore the Earth's crust by researching pH levels and acidity. In this environmental safety lesson, students identify the pros and cons of acidity within soil and how it affects plants. Students collaborate in a pH level...

Seventh graders determine the amount of blue food coloring in sports drinks and plot the concentration and absorbance data. They summarize the data and determine why companies need to know the amount of chemicals in their products.

Students explore acids and bases and the process of neutralization.T hey practice volume measurements and observe the neutralization of an acid directly through bubble formation and indirectly through indicator color changes.

Students discover the law of conservation of mass though experimentation.  In this chemistry lesson, students experiment with acid - base indicators to determine the presence of carbon dioxide. Students complete the labs with...

Students use the scientific method to determine the properties of various kinds of paints, use collected data to identify paint samples that are not properly labeled and use proper science safety techniques while working with chemical...

Students study karyotyping, which is a process in which chromosomes are cut out from an enlarged picture and arranged in decreasing order of size. They use a template to arrange and glue chromosomes to data sheet, indicate sample code,...
