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 explain the Chatelier's Principle. For this pH lesson, students identify factors that resist changes in pH of the ocean and why the ocean is becoming more acidic.

In this acids and bases worksheet, students complete 32 fill in the blank and short answer questions on acidity or alkalinity. They color molecular diagram according to the key.

Explore the range of pH using an assortment of household liquids. Scholars create their own pH indicators from cabbage and determine the pH of several liquids. To further their exploration, individuals use the same liquids to create...

Simulated acid rain, a dilute sulfuric acid solution, needs to be prepared for this demonstration. After a condensed lecture on acid rain, you will apply the solution to a sample of granite and a sample of limestone. Your young...

For this acids and bases worksheet, students determine the pH and pOH for a given solution. Students determine the conjugate acids for the given species. Students calculate which solution will have a higher pH. This worksheet has 16...

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

Learners use a Colorimetric test to measure pH and gain the importance to life in an aquatic ecosystem pH is. They explore the dramatic effect pH level can have on a water body. Learners test the pH level of many water samples.

How does carbon dioxide affect the world's oceans? The final installment in a series of six lessons has pupils research ocean acidification, then conduct an experiment to witness the delicate balance that exists in our seas. Materials...

You matter—unless you multiply yourself by the speed of light squared, then you energy! Scholars learn about matter, energy, the elements and so much more using an informative presentation. Completing the included worksheet creates a...

In this weak acid and base worksheet, students find the pH of solutions given the equilibrium constants for each of the weak acids and weak bases.

Students develop an understanding of how aspirin works and how understanding it's interaction with other chemicals in the body aided doctors in medical research. They complete a lab that compares the reaction of regular aspirin and...

In this pH worksheet, students are given information and directions as to how to calculate the pH of solutions. They use their calculators to find the pH of given solutions and apply what they learned about identifying acids and bases.

Students conduct the Biuret Test and the Bio Rad Protein Assay. They examine the spectrophotometer and graph molecular weights and the concentrations of the proteins investigated. They prepare solutions for the Bio-Rad test and use the...

At some point, all science learners experiment with pH. For this brief lesson, they simply use pH strips or a meter to find the pH of six different solutions. A useful worksheet that displays a data chart is included for your students.

In this acid and base worksheet, learners solve 11 problems including calculating pH of solutions, describing buffers, calculating solubilities of solutions and identifying acid-base pairs.

In this acid-base reaction instructional activity, learners calculate the ion concentration and pH for 6 solutions, graph titration results for 11 reactions and use Henderson-Hasselbach equations for three problems.

Students add the acid and base drop wise as the protein precipitates. If either are added too rapidly, students may miss detail or the protein may not have sufficient time to renature. Casein does not buffer the solution well when it is...

Has your class ever been astounded by the complexity of DNA analysis? Have they ever asked why genetic engineering has become so important to our daily lives? Young scientists perform DNA extraction on strawberries and explore how the...
