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...

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 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.

In this chemical reactions worksheet, students determine if solutions are acidic, basic, or neutral. Students give reactions' molecular equations and ionic equations. This worksheet has 14 problems to solve.

In this chemistry learning exercise, students solve twenty five multiple choice problems about a variety of chemistry topics. Students answer questions about equilibrium, solubility, reaction rates, titrations, and entropy.

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 aqueous equilbria worksheet, students write the solubility product expressions for the given salts. Kids determine what affects the solubility of salts. Students calculate the pH of a buffer solution. This worksheet has 14...

Students define the term acid rain, and the causes of acid rain. They locate regions where acid rain is most affected, and what can students deduce from maps of geology and soils in New York State. Students answer the questions why are...

In this solutions worksheet, students determine at what pH aspartic acid would be protonated. Students create buffer solutions with a certain pH and determine the solubility in certain solutions. This worksheet has 8 problems to solve.

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...

Sixty multiple choice questions cover the entire gamut of chemistry concepts. This is the local section of the U.S. National Chemistry Olympiad, where your chemistry candidates take a shot at entering the national competition. They...

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.

Young scholars perform experiments to determine the PH, acidity, and buffering qualities of a lake that make them sensitive to acid deposition.

Students examine and discuss the types of acids found in the stomach. They determine Alka-Seltzer is an acid based on tests. They discuss how this type of acid makes one stomach feel better.

Biologists extract the DNA from a strawberry. After completing the procedure, learners write answers to a few questions on the lab sheet provided. This is ideal lab practice during a DNA unit in your general biology course. 

Tenth graders explore DNA using online tutorial. They perform their own DNA extraction from a clove of garlic and identify the key components of DNA.

Students extract the DNA from a strawberry. In this DNA technology lesson, students describe what they think DNA looks like. They use a procedure to isolate and extract the DNA from a strawberry.

High schoolers compare different DNA and run a gel electrophoresis.  In this DNA lesson students complete a DNA activity that allows them to better understand its structure and function. 

Students applied various mathematical analyses to interpret their data. By using the resulting DNA fragment patterns from several enzymes students established a possible evolutionary relationship among the mice.

Students perform an experiment to extract and observe DNA from plant Tissue. They read about the procedure and relate it to the procedure used to isolate DNA from an endangered plant species. This is lesson three in a nine lesson unit...

Students study the basic function of DNA and then extract it from strawberries. In this DNA extraction lesson students examine DNA and see why the extraction of it is so important to scientists. 

Students explain the processes for separating DNA from tissue and separating complex mixtures.  In this exploratory lesson plan students complete a lab where they extract DNA.  

In this kidneys instructional activity, students review the function of the kidneys including what happens when the kidneys stop working. Students also compare kidney function in fish, frogs, and kangaroo rats. This instructional...

Learners explore electrophoresis, a technique used to isolate DNA. They assemble a gel chamber for separating mixtures. Students observe separation influenced by electric charge. They define separation through gel electrophoresis.
