In this thermodynamics instructional activity, students answer multiple choice questions about enthalpy and entropy, they calculate molar entropies and they determine equilibrium constants and free energy of reactions.

Ninth graders examine the Periodic Table. In this element lesson, 9th graders observe the chemical reactivity of elements. They graph the properties and discuss the trend in the group and period of elements. The students use math to...

The PowerPoint opens with video footage of the decomposition of nitrogen triiodide and then explains it with diagrams. Graphs of exothermic and endothermic reactions are exhibited, as well as one for the effect of a catalyst on reaction...

Tenth graders examine the heating curve of water when head is added constantly over time. They input values into a calculator as they record water temperature every thirty seconds as it is heated on a hot plate. They complete the...

The Cold War—with its roots in World War II—impacts the world today. Using an extensive curriculum, scholars consider its impact through primary sources, including speeches and propaganda, as well as other skills-enhancing activities. An...

Studying levers couldn't be more exciting! Learners build their own catapults and test the results as they make adjustments to the fulcrum. They compete against other groups to create the most accurate apparatus.

Second graders discover how matter changes from one state to another by observing melting ice cubes. They decide on means to warm the ice and predict what will happen. Students record how long it takes for the cubes to melt.

Second graders examine the properties of liquids and their classifications. They compare and contrast cups of different liquids and record their findings in journals. Students observe how liquids flow at various speeds and that unlike...

High schoolers study the different types of metals.  In this investigative lesson students watch a demonstration on the effects of temperature on atoms and take a tour through baone matter.

Fourth graders work together to collect air samples for testing. They determine the amount of pollution in the air in their community. They discuss their results to end the lesson plan.

Students work together to develop a container to keep an ice cube in a solid state. They identify the three stages of matter and test different materials for this experiment. They share their results with the class.

Students collect air samples to test it for air pollution. They are read the story The Lorax and discuss the effects of air pollution. They share their observations with the class.

Students follow the path of pollution from the Chernobyl accident. Students name and locate countries where radiation traveled to, describe how air pollution travels from one area to another, and seqence the travel of radiation in...

Students investigate coefficient of friction with respect to surface area and applied force in contact with the sliding force.

Eighth graders demonstrate how scientific principles can be used to provide resources in an emergency situation.  In this evaporation lesson students view a demonstration on a solar still and see a brief PowerPoint presentation. 

Eighth graders, in groups, explain the difference between physical and chemical changes.

Eighth graders observe two types of interactions in a sealed plastic bag. One bag contains baking soda and water, and the other baking soda and vinegar. They determine what evidence indicates that a chemical change is occurring.

Students use this design the illustrate how ink can be separated into its component chemicals using paper chromatography. They use five unknown samples of ink on pre-labeled chromatography strips are provided to students. Students use...

In this water vocabulary worksheet, students read and learn 12 words that pertain to water and the water cycle. Each word and definition is printed on a separate page in a snowflake shape.

Students examine the different changes in matter.  For this chemical change lesson students determine the amount of reactant made in a reaction using the law of conservation. 

Fifth graders diagram and label the parts of a tree. For this lesson on how trees obtain food, 5th graders diagram and label the parts of a tree, and determine the diameter, height, and age of a tree.

Students observe water change from a liquid to a gas state when heated and then return to its liquid stage when cooled. They learn that gas molecules move faster than liquid molecules. They discover physical properties that describe how...

Learners are introduced to the properties of solids, liquids and gases. They see that colloids are mixtures which display the properties of more than one of these states. They engage in an excellent experiment which demonstrates this fact.

Third graders define and discuss evaporation, precipitation, condensation, and collection, color web pages to illustrate Water Cycle book, listen to stories about Water Cycle, play trivia game to demonstrate knowledge of what they...
