Learners review properties of materials and define what pH tells them about matter.  In this pH levels lesson, students determine whether materials are acids or bases using indicator substances.

In this chemistry science worksheet, students identify the parts of a chemical reactions. Students name the major particles of the atom. Students apply knowledge about the atom, theories, and models.

From their sweat to the water vapor in their breath, astronauts recycle every possible drop of water while in space. After watching a short video describing the different ways materials are recycled and reused in space...

Students investigate acids, bases, and pH, and related this knowledge to the problem of acid deposition.

Students become aware of the environmental problems caused by acid rain and study the pH scale. They determine acidity of local rain water.

Students study La Chatelier's principle and identify how carbon dioxide may affect pH.  In this coral instructional activity students complete a worksheet on pH and observe a lab.

Students investigate the need for measuring concentrations in normality in titrations. In this titrations and normality lesson, students perform titrations and use different indicators to show they change colors at different pH values....

In this chemistry review worksheet, students answer and solve 95 questions about chemical reactions, hydrocarbons, functional groups, moles, acids and bases and solutions.

Students design and conduct a scientific experiment to test which of four antacids would be most effective for neutralizing acids. They rank the antacids in order from most effective to least effective and explain how they determined...

Students make their own pH indicator from red cabbage. Red cabbage contains a chemical that turns from its natural deep purple color to red in acids and blue in bases. Students boil the cabbage to get the pH indicator.

In this Archimedes' principle instructional activity, high schoolers answer 13 questions about the concepts of Archimedes' principle such as water displacement, buoyancy and force. The answer questions from a lab they did in class to...

Learners estimate the pH based on the use of an unknown substance, determine whether an unknown substance is acid, base or neutral, and evaluate, by the pH determination, which of the unknowns is the strongest acid or base.

Students test unknown solutions for pH levels to determine which organism can live in each environment. They name three substances that they think are acids. Students determine a solution is an acid or base. They define the term pH.

Learners perform a series of experiments on copper to produce a variety of copper compounds. In this chemical reactions of copper lesson plan, students use copper wire and nitric acid to produce copper nitrate. They then form a hydroxide...

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 wxplore acids and indicators by watching a demostration in which "magic" ink appears. They duplicate the demonstration by writing magic messages using phenolphthalein solution and painting the message with vinegar to show it.

In this pH activity, learners describe the pH scale and explain the initials "pH." Students classify solutions as acidic, neutral, or basic. Learners name compounds as acids or bases. This activity has 3 short answer questions and 5 fill...

For this water worksheet, learners read about hydrogen bonds in water and the differences in electronegativity between the oxygen atom and the two hydrogen atoms in water. Students answer four questions about the structure of water and...

Students propose and perform an experiment using the scientific method. The purpose of the experiment is to discern some earth materials or combinations of earth materials that best increases the pH of "acid rain". From the results of...

Radioactive decay, pH, properties of elements, organic compounds, and stoichiometry are all touched upon through this practice chemistry exam. It always helps learners to take a practice test in preparation for the actual exam. This...

Students determine the concentration of an unknown solution. This task assesses students' abilities to state hypothesis, develop procedures for investigation, plan for recording and organizing observations and data, collect data, create...

Students investigate the pH of solutions and they learn how to use different types of indicators. In this pH lesson plan, students test various solutions with pH paper and determine if they are acidic, basic or neutral. They also test...

In this titrations worksheet, high schoolers answer 4 questions about titrations and solve for the pH of solutions and their concentrations. They determine the quantity of a base needed to neutralize an acid.

Give young scientists a new appreciation of fresh, clean drinking water. After learning about the ways astronauts recycle their air and water, your class will work in small groups creating and testing their very own water...
