Students use the prelab as an introduction to the importance of DNA fingerprinting- a form of identification that us being accepted by both scientific and leagl experts. They prepare a gel for electrophoresis. DNA fragments, which have...

How do the hydrophobic and hydrophilic regions of a protein affect its shape? Science scholars explore the molecular properties of protein molecules using a detailed interactive. The resource allows the user to rotate the protein, view...

Students discuss and design a lab to measure pH of limestone, pyrite, limestone-pyrite mixtures and their control. They have their labs approved by the instructor before they begin. Students preform the lab and explore the acid-base...

High schoolers investigate the pH of various solutions with indicators. In this acids, bases and indicators lesson plan, students use a variety of indicators to test solutions for their pH. High schoolers determine which indicators are...

The first two pages provide a chart to complete with results of a lab test using different solutions and indicators. The data analysis questions will help your students understand the concentrations of the solutions and how they affect...

During a macromolecule lab, young chemists perform multiple tests, including iodine starch tests, to determine if eight mystery foods contain lipids, sugars, or starches.

In a hypothetical scenario, food chemists use titration to concoct a brine solution for producing the crunchiest pickles. They also analyze store-bought pickle juices. In addition to reinforcing titration techniques, the lesson requires...

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.

Students identify auxins from their structural formulas. They understand the process of refluxing in chemical synthesis. Students perform thin layer chromatography using silica gel plates to differentiate chemical substances.

Students list the common properties of acids and bases. They classify substances as acids or bases, by using pH and litmus tests and are able to explain the pH scale. They participate in a lab activity which reinforce their understanding.

Students discuss the importance of the Polymerase Chain Reaction for biologists. They explain what factors make the Polymerase Chain Reaction possible. Students explain the steps in thermocycling and what happens during each step.

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 chemistry Olympiad activity, pupils are given 2 lab problems to work on. They must explain their experiment they would carry out, show their data and write their results and conclusions of the lab and the process.

Long strings of amino acids fold themselves into stable peptides. The simulation allows scholars to observe the process in multiple ways. Using hydrophobic, hydrophilic, or a combination of proteins in three different solutions, the...

Five individuals in the class are "infected" with cholera! The rest of the class serves as investigators to discover the source of the outbreak. They test drinking fountains around campus for contamination. You, of course, will secretly...

Titration, and the lab skills that are needed to support it, is detailed here, with the reasoning behind standard solutions, concentration and volumetric analysis covered. Your young lab assistants will learn the skills of determining...

In this chemistry science activity, 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.

Students use a DNA strand to identify the component parts. They discuss an RNA molecule, protein fragments, and nucleotides. They explore how the order of nucleotides determines the order of amino acids in proteins.

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.

Students read about Humane Genome Project, examine structure and function of DNA, and participate in gel-electrophoresis lab. They complete Internet activity to test their knowledge of DNA.

Students extract DNA from their own hair roots. They run an electrophoresis gel to examine patterns of their DNA along with standard DNA. The experiment is based on a crime scene scenario.

After brainstorming what they know about ocean acidification, youngsters place eggs in acid to determine the effects on calcium-containing organisms, and add carbon dioxide to solutions with sea shell material to discover the impact on...

Uncover the basics of DNA structure through exploration activities. Collaborative groups build DNA models and recreate the process of replication. Then, using plant cells such as peas or strawberries, they extract a DNA sample.

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...
