In this chemical reactions worksheet, students apply the Le Chatelier's principle to determine the equilibrium shift in the reaction based on specific changes to the system. This worksheet has 2 short answer questions and 2 problems to...

Fifth graders explore energy transfer. In this thermal energy instructional activity, 5th graders stretch rubber bands several times and estimate the band's temperature change. Students identify this action as an example of thermal...

Fourth graders examine the effects of waves on coastal land. They discover how water's power can change the appearance of land formations.

Fifth graders are introduced to the concepts of weathering and erosion. In groups, they rotate between different stations to discover how each process effects different landforms. To end the lesson, they discuss each change in the...

Students use easily obtained materials to study ecological succession in a microbiological community. This investigation is appropriate for a variety of age groups. Elementary Students be fascinated by the changes occurring over time...

Middle schoolers are able to prepare and use pH indicators in paper form. They find out the color of the indicator paper plus test solution may change with time. Students use red cabbage to use for the indicator.

Learners 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.

Learners observe water as it changes form.  In this water lesson students observe, measure, and describe water as it changes state. 

Students complete an experiment to determine if there are bad microbes in food processing.For this bad microbe experiment, students use apples to see how they react to oxygen. Students test apples with chemicals to observe the changes.

High schoolers discover the law of conservation of mass though experimentation.  In this chemistry instructional activity, students experiment with acid - base indicators to determine the presence of carbon dioxide. High schoolers...

In this inorganic compounds worksheet, students complete 2 charts by writing the names or chemical formulas of given ionic and covalent compounds.

Young scholars design an experiment to test the effects of a change in the amount of dissolved oxygen of water on aquatic plants and animals. Questions are offered for exploration and experiment design. Results are tabulated and...

Tenth graders, from an environmental perspective, study the pros and cons of war. Distinctions between characteristics of biological, chemical and nuclear threats and the impact of economic development are considered.

Learners work in groups of 4-6 for the experiment/activity part of this exercise. They base their explanation on what they observed. Students observe how substances react chemically in characteristic ways with other substances to form...

Students design and conduct an experiment to compare the water-holding capacity of sand, soil, and moss. They measure the change in weight for each material after adding the same amount of water to each material.

Students study the historical background of Desert Storm/Desert Shield. They determine that not all Americans were in favor of the Gulf War and examine the Gulf War Syndrome. They discover that another possible cause pertains to...

Students investigate how varying the concentrations, volumes, and other factors affects reaction rates. Students design and conduct investigations to obtain data used to create graphs of an uncatalyzed reaction vs. a catalyzed reaction....

Third graders simulate weathering and erosion using sand and soil. They define weathering and the ways in which surfaces become weathered. Working as a class, 3rd graders complete various activities that demonstrate physical and...

Learners examine water. In this chemistry lesson, student examine the physical properties of water and how it changes from a liquid to a solid or a gas. This lesson contains links to a second and third complimentary lesson on...

Second graders describe how energy moves from the Sun to the photovoltaic cell to the wire and to the load. In this solar cell simulation lesson, 2nd graders demonstrate the movement of photons and electrons to emulate how solar energy...

Students identify the effect of light on objects. In this scientific inquiry lesson, students use a chart to write a hypothesis about what will happen when colored construction paper is left in sunlight. Students observe and discuss the...

Young scholars conduct an experiment to find out if there is salt in the ocean. In this scientific inquiry lesson, students pour a cup of salt water onto an aluminum plate and observe the changes over a few days. Young scholars complete...

In this energy worksheet, students calculate the enthalpy of chemical reactions to answer 9 problems. They determine whether the reaction is exothermic or endothermic.

Tenth graders study disease and how it changes normal body functions.  In this research lesson students research a disease and use a word processing software to construct a presentation.
