Middle schoolers observe chemical reactions using post-1982 pennies. They observe the reaction of an acid with zinc but not copper under the same conditions over a two week period.

Students analyze the relationship between density, buoyancy, and salinity. In this chemical properties lesson, students read a background activity for the lesson and experiments to the topics. Students discuss the questions and complete...

Learners explore the Cambrian explosion and Paleocene extinction events. In this climate change lesson, students read articles to link evidence they find to extinction and climate change.  Links to the articles are included in the...

Students investigate how changes occur on the surface of the earth through erosion and glaciation. They observe what happens to salt and iron after they interact with water and vinegar, and analyze what occurs when water is sprinkled on...

Fifth graders familiarize themselves with more abstract chemical/physical changes that are directly connected to Ohio. They use their knowledge of chemical and physical changes to distinguish these two, even though they may not be...

In this physical science exploration, small groups place a piece of antacid tablet into a film canister and step back to time how long it takes for the top to pop. They repeat the activity, altering either the amount or temperature of...

Two topics are covered by this chemistry worksheet: redox reactions and electrochemistry. Thorough review notes are followed by a series of multiple choice questions about oxidation numbers, redox reactions, electrochemical cells, and...

Introduce physical science learners to the forms of energy using this PowerPoint. The concluding slides present scenarios for discussing the transfer of energy from one form to another. Informative text is crisp and attractive, but the...

Open this instructional activity by giving a brief history of ice cream. Using liquid nitrogen to lower the temperature, preteens make their own confection. The accompanying activity sheet queries learners about freezing point, the...

In this chemical equilibrium worksheet, students work with the LeChatelier's Principle to determine the effects of changes in concentration or partial pressure and the effect of changes in total pressure or volume. This worksheet has 9...

Students explore Le Chatelier's Principle. For this lesson about chemical equilibrium, students do an experiment with several different activities . Students observe as they do the experiments and understand the outcome. Students become...

In this chemical reactions learning exercise, learners determine how mixtures shift toward reactants or products to reach equilibrium. For given reactions, students determine how concentrations will change when adding or removing gases...

Students work together to observe the bond lengths of single, double and triple bonds. They make their own predictions about the strength of the bonds and chemical reactions. They answer discussion questions to complete the lesson.

In this chemistry learning exercise, students calculate specific changes that take place with different chemical reactions. Students indicate whether the reactions are endothermic or exothermic and spontaneous or nonspontaneous.

In this chemical reaction worksheet, students label the missing particles as natural decay, induced, fission, or fusion. Students calculate the energy change for the given reactions. This worksheet has 6 fill in the blank and 4 problems...

In this balancing chemical reactions worksheet, students balance equations, identify electrons gained or lost in atoms and identify the number of atoms of each element for the reactants and products in equations. They also answer 3...

Students experiment in a lab and observe chemical reactions and pH changes.  In this experimental lesson students participate in a lab then write their observations and fill out a worksheet. 

Students review some examples from the website "We Are What We Do" and examine the impact of lots of people making small changes to their lifestyles. They complete a worksheet to introduce them to the variety of challenges. Students...

Young scholars describe the Le Chatelier Principle. They participate in an experiment in which they observe the changes in an equilibrium system. They answer discussion questions to end the lesson.

In this chemical reactions worksheet, students determine what happens when specific stresses are applied to a reaction. Students calculate the equilibrium constant with respect to pressure. This worksheet has 20 problems to solve.

In this chemical reactions worksheet, students use the LeChatelier's principle to predict concentrations. Students determine if products or reactants are favored at equilibrium for given equilibrium constants. This worksheet has 5...

In this thermodynamics worksheet, students predict the change in reaction values for the 14 thermodynamic reactions given.

Students complete a unit of activities to learn about states of matter and how to measure matter. In this matter lesson, students complete 8 lessons to learn about matter, its states, and how to measure matter.

High schoolers observe the reaction of living cells to mechanical and chemical stimuli by introducing different stimuli to an organism under a microscope and recording the response.
