Students explore the science of toxicology and the relationship between a toxic reaction (response) and amount of substance (dose). They observe two demonstrations illustrating the concept of dose-response.

Students explore acids and bases and the process of neutralization.T hey practice volume measurements and observe the neutralization of an acid directly through bubble formation and indirectly through indicator color changes.

Water is crucial to survival. Scholars gain an appreciation for water by reading about it, learning about its atomic properties, and investigating its properties through six stations in a lab activity.

An introduction to the noble gases shows how full electron shells on an atom makes an element unreactive. Your class will then develop an understanding of how sodium and chlorine react ideally because of their electron arrangement....

Explore the water cycle in all aspects with a resource packed full of activities and lessons. The 37-page packet comes with vocabulary, a game, writing prompts, printables, and opportunities to journey through the stages in the water...

Ahh, the rules of attraction...intermolecular attraction! Introduce your chemistry crew to the other forces that influence the behavior of atoms and molecules alike with a simple interactive. Pupils push and pull polar and non-polar...

If you need a way to assess the concepts in your physical science class, use an extended set of worksheets as a midterm or final exam. It includes questions about density, physical and chemical matter, speed and velocity, weight and...

Students use a computer program to study elements and the periodic table. They follow the directions on the computer program, and answer the questions presented. The program is self scoring, and students may print a certificate that...

In this economics worksheet, students respond to 4 short answer questions about types of economies and theories of economists.

Students determine the best solvent system for separating a methylene blue/sodium fluorescein mixture by thin layer chromatography. They conduct an initial TLC separation using ethanol and a different solvent mixture and analyze the data...

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.

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...

Learners illustrate the changes in the properties of a material at its glass transition point. They gather data which they use to construct graphs regarding elastic modules versus absorption modulus, tangent delta, and the effect of...

Students prepare a sample of a commercial hand lotion for analysis by HPLC to determine the percent composition of two common cosmetic preservatives, methylparaben and propylparaben. They perform the analysis and the data is evaluated to...

Students investigate issues of degradation and weathering of polymeric materials during their useful life. They evaluate photodegradable plastics and their viability as an environmental solution for litter and investigate the qualitative...

Scholars apply concepts learned in both Algebra II and Chemistry to answer the questions on the provided worksheet. The activity allows for extra practice in both classes and helps connect concepts usually taught in isolation. The...

Matrices help solve systems of equations in chemistry, computer graphics, circuitry, probability, and more. The second lesson in a seven-part series focuses on using matrices to balance chemical equations. Pupils rely on the Law of...

Do you know the name for the biological study of interactions? A short presentation with accompanying worksheet introduces individuals to ecology. The materials offer a broad overview of the subject and the levels of organization to...

Find a statistical reason for a fresh start. Using a hypothetical scenario, individuals research statistical data of three different cities. Their goal? Find the best statistical reason for a business to move to a new location. Their...

How fun would it be to teach the concept of stoichiometry while allowing your chemistry class to assemble a classic campfire treat? This fun and engaging activity allows pupils to explore the principles of the chemical theory while...

Household materials can be used for more than cleaning! In this collaborative experiment, emerging chemists use products such as vinegar and liquid antacid to explore chemical reactions that commonly occur in the human body.

What does viscosity have to do with splatter? An activity shows that the viscosity of a substance is inversely proportional to the distance of its splatter. Learners conduct the experiment by collecting data, graphing, and analyzing...

Explore the makeup of the earth's atmosphere. Using the set of specific experiments, pupils examine the main elements and compounds present in the atmosphere. Their study extends to investigate the effects of atmospheric...

Students identify the factors that influence reaction rates. In this chemistry lesson, students design an experiment to test one factor they identified. They perform the experiment and share the results to the entire class.
