Students participate in a laboratory investigation in which they observe the effect of temperature and pH on enzyme activity. Students also examine exposure to heavy metal ions and the effect that may have on enzyme activity.

Learners find the relationship between the variables based on experimental data. They determine mathematical relationship between pH and the amount of hydrogen Ions in solution.

Students conduct an oxidation experiment in which they must determine how much hydrogen peroxide (H2O2) is actually in a store-bought solution of H2O2.

Ninth graders examine the electrolysis of water by completing an experiment.  In this water lesson students will explain how hydrogen can be extracted from water and how energy flows through an electrolysis system. 

Students use indicator paper to determine if substances are acidic, basic, or neutral. They test for Ph levels in them. They investigate the effect of oxygen on darkening fruit cut and exposed to the air. They observe vitamin C as an...

High schoolers investigate how to denature proteins. In this denaturing protein lesson plan, students explore the different ways to denature proteins in the lab. They use heat, acids and bases, organic compounds and heavy metals to...

Students test unknown solutions for pH levels to determine which organism can live in each environment. They name three substances that they think are acids. Students determine a solution is an acid or base. They define the term pH.

Students investigate empirical formulas for molecules. In this empirical formulas lesson plan, students use paper ions to form formulas and they show these are empirical formulas. They use ions of carbon and hydrogen showing electron...

Students experiment to determine the effect of the frequency of collisions between atoms or ions of the reactants. They investigate the rate at which aluminum replaces hydrogen from a solution of hydrochloric acid.

Using cabbage juice as a pH indicator, future scientists explore the effect of increasing carbon dioxide on the pH of the ocean and relate it to the health of coral reefs. Ideal for an earth or environmental sciences course, this lesson...

Explore the range of pH using an assortment of household liquids. Scholars create their own pH indicators from cabbage and determine the pH of several liquids. To further their exploration, individuals use the same liquids to create...

What can we learn from the data? Young scholars analyze actual solar data to answer specific questions. The activity presents an opportunity for an open-ended investigation of the data to conclude a five-part series on solar winds.

Students think of one way to detect photosynthesis in plants besides those ways shown in class. They identify the reaction that occurs during photosynthesis. Students define the difference between an acid and a base. They identify acidic...

Students are presented with the question, "Do plants that grow underwater use oxygen?" They create an experiment to test the presence of dissolved oxygen in the water using provided materials. Student experiments include a control jar as...

Students recognize how the climate of the Hudson Valley has changed since the last glaciation. They explain these changes using a reconstruction of the land use changes in the Hudson Valley composed of confetti, Ziploc bags and other...

How does carbon dioxide affect the world's oceans? The final installment in a series of six lessons has pupils research ocean acidification, then conduct an experiment to witness the delicate balance that exists in our seas. Materials...

Students use the basic principles of Chemistry to determine pH levels. Elements of the Periodic Table are also included in this lesson plan.

Pupils 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...

Students are shown how dissolved oxygen enters the water. They are taught the difference between a water sample that has been exposed to the air and one that has not. Students brainstorm what organisms need to survive. They use dissolved...

High schoolers test water for a least one chemical characteristic. They hypothesize how a storm event might change the chemical characteristics of a stream. Students collect water samples and use the chemical test to test the water.

Students visit a local stream, pond, creek, or river and collect macroinvertebrates. They sort macroinvertebrates and identify each species using a dichotomous key. Students decide on trophic levels and construct a possible food web for...

students discuss the importance of light and the consequences of living without it. Using a plant as a demonstration, students predict and observe what happens to a plant when it does not receive enough light. In groups, they experiment...

Students are taught that a watershed is, what types of basic land cover are impermeable and permeable to water. They trace the flow of water around their school and around their home. Students determine what watershed their school is a...

Learners 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...
