Le Chatelier's interest in thermodynamics and building materials such as cement and plaster led to the Le Chatelier Principle in 1884. Activity 13 in a series of 36 extensively explores chemical equilibrium. Learners read about...

Silver pennies and copper nickels are made possible by applying some chemistry. Learners use electrolysis to coat a penny with zinc sulfate and a nickel with copper sulfate. Their investigation builds an understanding of electroplating...

Can you go ice fishing in the ocean? Learners examine the freezing point of different saltwater solutions. Each solution has a different concentration of salt. By comparing the freezing points graphically, they make conclusions...

A set of 27 slides systematically shows how weathering, erosion, and deposition contribute to soil formation. Both chemical and mechanical weathering are described, as are resulting soil layers and properties. There is no longer any need...

Did you know there are 20 volcanoes erupting at any given time? Pupils look at various igneous rocks, read local geologic maps, and determine if their area has a history of volcanic activity. A reading passage and analysis questions...

Through a hands-on activity, an acetone-spinach solution is pre-made and learners use this solution to separate the pigments found in spinach using chromatography. The comprehensive resource includes an analysis and conclusion...

Examine how organisms interact through a hands-on experience. Learners study population dynamics and distribution during an informative five-lesson unit. The focus is on the ocean environment and the organisms within it.

Though this is meant to be second in a two-part lesson, the two are not dependent on each other. Pupils play the roles of visible light rays, light or dark surfaces, and carbon dioxide molecules. They interact and react according to...

Pupils create their own compost.  In this soil instructional activity, students fill a bag with waste and soil, in order to create a mini compost bin. Pupils observe the baggies over a 6 week period, they record their findings and...

For this solutions worksheet, students read about how people first learned to use metals and to combine metals to form alloys. Students write an essay telling the story of how ancient people first learned to cause physical changes in metal.

In this solutions worksheet, students soak a pipe cleaner in hot water and a supersaturated solution of 20 Mule Team Borax. Students leave their pipe cleaner in the solution for 30 minutes and then observe. They put it back in over night...

Students make ice cream as a result of viewing changes of states of matter. In this matter lesson plan, students learn how heating and cooling can effect a state of matter to change.

In this chemistry worksheet, students find the words that are related to atoms and molecules. The answers are found by clicking the link at the bottom of the page.

Heat up your lessons on boiling points. The resource provides a three-part activity: first, groups find the boiling point of solutions; second, they create boiling point curves for salt and sugar solutions; and third, they mix a solution...

Students participate in various air experiments to understand that air is all around us. In this states of matter lesson, students focus on the role of air in the water cycle. Students understand that air is densest near the ground....

Fifth graders study the properties of metals and use them to identify different properties.  In this metal properties lesson students complete a demonstration .

This is mostly an exploration of race through an interactive website, class readings, and discussion. Individuals take an online quiz about race, they answer questions on a worksheet by visiting another website, and discover that race is...

Topping this worksheet is a comprehensive collection of notes about phase changes. The phase change graph is displayed, along with formulas for the gas laws, and information relating energy to change of phase. After reviewing these...

Students examine mixtures and solution properties by making a borax polymer. In this chemical reactions lesson, students make a putty out of borax solution mixed to create a polymer.

Fifth graders perform experiments with color mixing and color changing. They observe the differences between physical and chemical changes and record their observations in journals.

First graders complete a variety of experiments with solids, liquids and gases. They read books about matter, identify the characteristics of solids, liquids and gases and the sort and classify a variety of matter. Students make...

Eighth graders discuss atoms and electrons as well as atoic structure. They view atomic structure via the computer. Students watch a demonstration in which the teacher demonstrates glass tubing turning yellow in a Bunsen Burner flame....

Students examine a crushed rock and sort the minerals they find in that rock by color and other properties.

Students create ice cream in a bag and snow ice cream to study the effects of freezing on foods.  In this ice cream lesson, students understand the effects of freezing on cells.
