More than half of AP Chemistry test takers earn a high enough score to get college credit. Improve that statistic by using past test questions including precipitate, molarity, and chemical equations to prepare for a future exam. The...

Fourth graders conduct experiments heating water. In this inquiry-based early chemistry lesson, 4th graders use the materials given to experiment with the process of heating water. Students draw conclusions based upon their findings...

Ninth graders are presented with a problem that has to be solved. The scenario is a mystery that is purely hypothetical. This does draw on the knowledge of previous lessons. The lesson plan contains background knowledge explaining the...

Students study DNA by isolating it from plant tissue. They determine the purpose of each step in the isolation procedure as it relates to the physical and biochemical characteristics of the genetic material

In this buffers worksheet, students identify the systems that could function as a buffer solution. Students determine the pH of a solution and the pH of the buffer. This worksheet has 6 problems to solve.

Students examine how every element is classified based on the physical and chemical properties.  In this properties of metals lesson students divide into groups, complete a lab and finish a data sheet. 

Students work in groups of 4-6 for the experiment/activity part of this exercise. They base their explanation on what they observed. Students observe how substances react chemically in characteristic ways with other substances to form...

Students investigate the concept of a polymer using an experimental design of protecting an egg in a bookbag. They test the properties of polymers and form an educated solution to the proposed problem. Then they describe the steps used...

For this chemical reactions worksheet, learners answer follow up questions to a lab where they were observing chemical changes in reactions after mixing products such as hydrochloric acid and sodium bicarbonate. They answer six questions...

Students extract DNA from an onion using household equipment and supplies.

In this chemistry of life worksheet, students will review key terms of plant cell structure and chemistry by reading 13 clues to complete the puzzle. Word bank is included.

Students separate a mixture of pigments with ion exchange chromatography and predict whether the ion-exchange matrix is positively or negatively charged based on the type of pigment bonded to the matrix.

Students apply the scientific method and safety rules to aquatic pH. They test unknown solutions for pH levels.

Students conduct an experiment in which they systematically separate cations from a mixture of substances. They use the following types of reactions to do so: precipitation, acids and bases, oxidation and reduction. They compare a...

Students investigate the effects of an acid and a base on the structure of milk protein. They observe the changes to droplets of milk when adding ammonia and lemon juice and relate the changes to old, curdled milk. An extension using...

Students discover how underground rock formations grow. They perform various activities based on grade level.

Students make a starch-glucose solution and pour it through gel in order to separate the starch from the glucose. They examine how starch is a larger molecule than glucose and test for the presence of these substances using other...

Fourth graders identify eleven white substances that are commonly found in the household. They, in pairs, perform experiments on a variety of substances, and must identify them based on the reactions they observe.

Students isolate DNA from different food sources. In this biology lesson, students research DNA extraction. They analyze DNA stands collected from the lab, and compare the differences between each.

Students visualize DNA from cells and explain the basis and importance of the Gram-stain reaction and to perform the KOH test equivalent.

Students apply measurement skills using the metric system. They explain the process of isolating DNA from other cell contents. They apply knowledge of cell structure to explain the process of isolating DNA.

Young scholars explore DNA and restriction enzymes using fragments of DNA separated by electrophoresis on an agarose gel. They analyze the results to see "whodunit".

Students observe caring for eggs and chickens.  In this hatching lesson students brainstorm what they know about chickens and carefully watch what happens.

Laughter may be the best medicine, but aspirin is also important. Young chemists analyze aspirin tablets using titration in this lab experiment. They then repeat the entire experiment using a different aspirin brand.
