Let your brilliance shine like the sun. Future mathematicians and scientists consider given data on the abundance of different elements in the sun. The assessment task requires consideration of how these different abundances relate to...

In "Nuclear Arthmetic," first-time physical scientists examine atomic structure and the periodic table of elements. The are given the formula, "N = A-Z," in which N is the number of neutrons, A is the atomic mass, and Z is the atomic...

Students investigate elements by by defining scientific terms.  In this Periodic Table of Elements lesson, students utilize a glass of water, and powdered fruit drink to perform a lab activity demonstrating properties of certain...

Eighth graders read and interpret the Periodic Table. They also make decisions on how to group and arrange different kinds of matter and draw the structure of atoms of pure elements. Finally, 8th graders contrast and compare basic...

Ninth graders examine the Periodic Table. In this element instructional activity, 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...

Young scholars compare Jupiter and Earth. For this Earth and space studies lesson, students compare the composition of Earth and Jupiter and analyze how the composition affects the rate at which the planets spin.
