Litmus paper, why so blue? A chemistry lesson includes a pre-lab activity, practice calculating pH, an experiment measuring the pH in acids and bases, a titration demonstration, and a titration experiment. 

Young scholars experiment with acids and bases using technology-based "probe-ware", computers, and household products in this exciting biology/chemistry lesson. The lesson was written for an advanced 6th grade class.

What is in that double helix? Explain intricate concepts with a variety of creative activities in a lesson that incorporates multiple steps to cover DNA structure, nucleic acids, and proteins. Pupils explore the history of DNA structure,...

Pairs work together to determine whether unknown solutions are either acids or bases by using a red cabbage indicator solution. After determining the general pH of the unknown solution, classmates blow into the same indicator after...

Students combine different materials to create chemical reactions. In this chemical reaction lesson plan, students will combine different materials to create chemical reactions and define these results as acids or bases. They will also...

Students are taught how to format and enter data into an Excel spreadsheet. They make a graph and interpret graphed data. Students discuss possible impacts of water chestnut invasion. They graph data on water chestnut. Students report...

Students are taught that invasive plant removal can have a variety of impacts. They are shown this by using graphs. Students view maps of vegetation change on Iona Island. They discuss implications of changes on marsh birds using data...

Before graphing and finding distances, learners investigate the coordinate plane and look at patterns related to plotted points. Points are plotted and the goal is to look at the horizontal and vertical distances between coordinates and...

Hate to vacuum, but enjoy using a vacuum pump? Explore a lesson that starts with a demonstration of boiling water at various temperatures by using a vacuum pump. Then scholars design their own experiments to measure vapor pressure and...

Take charge of your biology class by using this exciting analogy to relate the ATP process with batteries. Pupils use batteries and rubber bands to simulate the phosphate bonds between molecules in the body. They measure the distance in...

The University of the State of New York has designed a series of exams for high schoolers. This chemistry exam is one of the most comprehensive and well-written that you will ever find. It consists of 84 questions in a variety of styles,...

Learners 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 explore the issues that influence our environment and research ways to decrease the negative impact that humans have on the environment. Misconceptions about environmental issues are addressed in this lesson.

Students identify the different types of fractals. In this geometry lesson, students use math to analyze different biological phenomena. They collect data from the experiments and construct graphs.

Students 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...

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...

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 lesson keeps Avogadro relevant to your class all year long. 

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...

Learners 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.

Students 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 instructional activity, students collect and analyze data regarding the pH of various liquids.  Students display their data in various types of...
