Seventh graders construct a lunch box that maintains functional temperature zones and does not allow heat transfer between the zones. They examine the transfer of heat, the capacity of certain materials to hold heat, and how the...

Students use the scientific method to determine physical and chemical properties of unknown substances. For this scientific method lesson plan, students discuss chemical and physical properties of substances as a class after a...

Fourth graders examine and identify chemical and physical changes in a variety of substances. They observe a vinegar and baking soda demonstration, and a water, laundry detergent, and Epsom salt mixture demonstration. They discuss the...

Sixth graders use the scientific method to test variables of evaporation. For this evaporation lesson plan, 6th graders test a wet handprint on a paper towel and relate this experiment to weather conditions.

In this thermodynamics worksheet, 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...

Eighth graders determine the presence of starch and sugar in unknown solutions. This task assesses students' abilities to observe, record and interpret data, classify, generalize/infer, construct data tables, and identify sugar and...

Students compare the times it takes the milk in each of two cups to curdle. They are told that an enzyme that is added to the milk, rennin, is involved in the natural curdling process of milk. Students are asked to consider what...

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.

First graders understand that gases take up space even though you can't see or smell it. This is done through many experiments like trapping air in different sized bags, using balloons and plastic bottles, and blowing bubbles. They...

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...

Students study the different types of metals.  In this investigative lesson plan 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.

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...
