Pupils determine the concentration of an unknown solution. This task assesses students' abilities to state hypothesis, develop procedures for investigation, plan for recording and organizing observations and data, collect data, create a...

Most pupils know about the flu, HIV, and other viruses, but they don't know what each actually looks like. This interactive shows their relative size, structure, and allows for comparisons. It stresses the similarities and differences...

Scientists have been studying exothermic reactions before they were cool. The instructional activity begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the...

Students measure the effect of water temperature on the rate of a chemical reaction, similar to the interaction of a weak acid and carbonate rock, using hot water and effervescent antacid tablets.

Students are shown how temperature affects dissolved oxygen and they create a graph showing this relationship. They think about the adaptations of animals to live in different water temperatures. Students test four different water...

In this acid-base reaction instructional activity, learners calculate the ion concentration and pH for 6 solutions, graph titration results for 11 reactions and use Henderson-Hasselbach equations for three problems.

Want my name and number? It's 6.0221415 times 10 to the 23rd, and my name is Avogadro. Providing nine different activities, experiments, and labs, this instructional activity keeps Avogadro relevant to your class all year...

Seventh-graders come in to science class to find a file on their desks detailing a crime to be solved! As a demonstration, you simulate the restriction of DNA samples and separate them by electrophoresis. From the gel, learners can...

Students investigate the effects of acid rain by conducting an experiment with bean sprouts and graph the results. In this Environmental Policy lesson, students visit a museum to identify examples of foreign and domestic policy on...

Students construct flow diagrams of the carbon and nitrogen cycle processes. They identify sequences in each cycle that are affected by human impact and present their research to the class.

Pupils determine the concentration of acetic acid when the concentration of the base with which is titrated is known. They investigate how to weigh a sample using the balance, measure volumes using graduated cylinder, explore the...

Students investigate the pH of a liquid.  In this middle school mathematics/science lesson, students collect and analyze data regarding the pH of various liquids.  Students display their data in various types of graphs as they...

Beginning biologists demonstrate their grasp on cellular respiration, photosynthesis, and energy flow though ecosystems when completing this worksheet. Fifteen multiple choice and short answer questions test their knowledge. Because of...

Students view an illustration of the Hudson River watershed and identify the bodies of water shown. They discuss what happens when fresh and salt water mix. Students view a teacher demonstration of the stratification of fresh and salt...

What is a chemist's favorite plant? Stoichiome Tree! Scholars produce hydrogen gas by reacting magnesium with hydrochloric acid. Then they calculate the molar volume of the gas produced before answering assessment questions. 

Learners use the scientific method to determine the properties of various kinds of paints, use collected data to identify paint samples that are not properly labeled and use proper science safety techniques while working with chemical...

Young scholars, in groups, research, analyze and synthesize information on genetic diseases. After watching a video on genetics, groups perform research on a variety of genetic diseases and present their findings to the class.

The majority of this presentation is a collection of diagrams and graphs that back your lecture on biogeochemical cycles. The last few slides define ecosystems and the Gaia hypothesis. You may find these slides valuable, but will...

Fifth graders conduct experiments to compare seed germination and plant growth rates. They construct a hydroponic plant unit and a lighthouse. They care for the plants for a month and collect data for graphs. They write a report.

Students identify various kinds of paints by using the scientific method.  In this solvents lesson students collect data and identify paint samples while working in teams.

Tenth graders investigate the process of how specific products are made from trees. For this chemistry lesson plan, groups of students must choose among ice cream, bubble gum, paper, toothpaste and lipstick. They research, design...

Learners view a video that presents how viruses attack the body and how the body's immune system responds. They simulate the spread of an infectious disease and establish the identity of the original carrier.

Students explore the Earth's crust by researching pH levels and acidity. In this environmental safety lesson, students identify the pros and cons of acidity within soil and how it affects plants. Students collaborate in a pH level...

Tenth graders develop a hypothesis and explain what they observed on an activity.  In this investigative lesson students observe osmosis and report their data using a graph.
