The Making of Macromolecules
Compare and contrast macromolecules made from the same elements. Young scholars learn how the structure of a molecule has as much influence on a compound as the elements in the molecule. They experiment with molecular model kits to...

The Atom
In this atom worksheet, students read about the parts of the atom and how atoms combine into molecules and compounds. Students learn how to read a periodic table. This worksheet has 20 fill in the blank and 10 matching questions.
Curated OER
Composition of the Atom
Students investigate the structure of the atom and its composition. In this atom structure lesson, students find the area of cut out circles and drop pens into the circles. They count the number of marks in the circles and relate their...
