Scratch and sniff an introduction to organic chemical reactions. A creative lesson has individuals study the esters commonly used in scratch-and-sniff stickers and advertisements. Following the lab procedure, scholars create the organic...

Here is a thorough lesson on safety in the chemistry lab. Chemists review a detailed list of safety rules, draw the layout of the laboratory area to include emergency equipment, identify hazard warnings, and consult the MSDS in order to...

Wolves eat better when the bunny population increases, but how long does that last? A series of 12 biology lessons uses the sixth installment to explore the predator-prey relationship between bunny and wolf populations. Young scientists...

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...

Students complete a variety of lab and discussion activities as they are introduced to ethics and honest lab practices. They perform various biology, chemistry, or physics labs which test their ethical lab practices.

In a simulated crime science investigation, chemistry or physics sleuths use spectroscopy to analyze solutions. The instructional activity gives learners practice making salicylate solutions, using spectrophotometers, calculating...

College-level or AP chemists use phthalic anhydride to synthesize two different polyesters, one linear and one cross-linked in structure. A detailed materials list and well-written procedures are provided on a lab sheet. Learners write...

Immerse your chemistry class in the world of organic chemistry! Science scholars isolate acetaminophen from an over-the-counter sample during an intense and interesting lab. Groups use many different separation and analysis techniques to...

Investigators collect the carbon dioxide produced when an antacid tablet is activated and identify what alteration produced the most gas. They also collect the gas in a buret in order to practice precision. Then they choose between two...

Here are the instructions for leading your advanced chemists though the process of measuring the nonvolatile components in a sample of paint. No student handout is provided, so you may want to create one based on the procedure explained....

Students preview a copy of the lab experience and "cookbook translator" prior to the actual lab experience. They participate in the lab experience and complete the "cookbook translator" for evaluation at the completion of the laboratory...

Students investigate the effects of adding or removing a reactant or a product on chemical equilibrium. In this equilibrium lesson plan, students add or remove ions to solutions to determine the effects on equilibrium. They make...

Young scholars determine the heat of fusion of ice. In this heat of fusion lesson plan, students use a calorimeter to measure the molar heat of fusion of ice. Young scholars determine the heat required to melt one mole of ice using hot...

Crystals are more than meets the eye! Can learners tell them apart simply by observation? As they examine five samples with a magnifier, they find that appearance alone is not enough. This serves as an introduction to a mini unit on...

Physical science investigators mix sugar and food coloring into different cups of water and cooking oil to compare how the solid and liquid behave in each. As the introduction to this unit on dissolving, it is relevant.

Can a sponge cure cancer? Life science pupils visit the drugstore under the sea in the fifth lesson of six. Working groups research the topic then get hands-on experience by testing the inhibiting effects of several plant extracts...

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 predict the conditions necessary for bacterial growth, test their predictions and at the same time practice the aseptic techniques and safety procedures needed when working with bacteria.

A few of the components of this lesson are not possible to carry out because the rock cycle diagram and challenge handouts are not included. Hopefully, you already have your own rock cycle diagram or worksheet to use as a concept...

Pupils list sources of phosphorus in soil. They explain how phosphorus is removed from the soil and used by plants. Students list the symptoms of insufficient or excess phosphorus. Pupils perform experiments to examine the effect of...

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...

Although the worksheet for the lab activity is not included, this is an activating activity for your class to do when learning about the greenhouse effect. They lay three thermometers underneath a lamp: one out in the open, one under a...
