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...

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 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...

Students use reference skills to locate information about the periodic table. They identify elements by name, atomic number, atomic mass, symbol and properties. Students use mathematical processes to find the number of protons,electrons...

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...

How do you get a theorem named after you? Euler knows what it takes! The third lesson of five asks pupils to use an interactive activity to compare the faces, vertices, and edges of seven different three-dimensional solids. They use...

Seventh graders, in groups, complete an Isotopes model and notice that atomic masses are decimal numbers. These masses are an average of all the isotopes of that element.
