Learners create a model of a column of air and discover one of the reasons why low and high pressure systems exist and why low pressure is often associated with bad weather.

Students consider the causes of density at a microscopic level. They then discover that one cause of density has to do with how many protons and neutrons the material contains.

Students conduct research of the history of atomic theory. Information is presented from Democritus and Aristotle to the early Renaissance using the Internet and video.The integration of technology allows for a vast amount of research...

In this chemistry worksheet, students examine the concepts of mole and molarity in order to apply in the laboratory setting. The sheet includes in depth background information.

Students examine the periodic table and how it was developed.  In this chemistry lesson students identify common properties and uses of elements within a family. 

Young scholars explain how the elements are arranged in the periodic table. In this chemistry instructional activity, students determine the subatomic particles for certain elements. They research the physical and chemical properties of...

Students read and discuss an article about carbon dating, then participate in a hands-on lab to discover how carbon dating works. Students also write a letter to a friend explaining the process, and how archeologists use the process to...

Students identify the different periodic trends. In this chemistry lesson, students discuss how elements are arranged in the periodic table. They apply what they have learned in a Jeopardy team game.

Young scholars explain how elements are arranged in the periodic table. In this chemistry instructional activity, students group the eggs according to a certain pattern. They compare this to elements in the periodic...

Students study polyatomic ions and write binary and ternary ionic chemical formulas. They explore putting together different monatomic ions and coming up with as many chemical formulas as possible. They play a game similar to memory...

Eighth graders investigate the different elements of the Periodic Table. For this chemistry lesson, 8th graders pick an element to research, then present to the class using a powerpoint presentation or a poster.

Students study the difference between types of ionizing radiation and how elements are transmuted. They determine that radiation is normal and surrounds us. They calculate the amounts of alpha, beta and gamma radiation emitted from a...

Young scholars research chemical formulas and balance chemical equations.  In this chemical equations lesson students complete a class activity on chemical equations and answer questions.

Students apply their knowledge of relativity and nuclear radiation to the concept of cold fusion. They also read the article from the website listed in the related and resource websites and discuss the article with the class.

In this activity, students apply what they have learned about weighted averages, isotopes, and systems of equations to a new situation - coins in a sealed container. They learn some historical information regarding the composition of...

Students explore the concept of the mole as a measure of quantity. They build spreadsheets that allow them to convert between moles, grams, and atomic mass units for given quantities of everyday items, elements, and simple chemical...
