Students investigate the length of various objects. In this measurement lesson plan, students convert one metric unit to another. They explain the importance of a uniform system of measurement.

In this science worksheet, students use the key code on the right to unscramble each of the scientists. They also match each of the scientists found to their correct description.

Students demonstrate that isotopes of an element have different masses. They illustrate atomic mass and neutrons. The periodic table is examined in length. Display of a collection of atoms is surveyed.

Young scholars review atomic numbers, positive and negative charges, and the periodic table. They examine the relationships among protons and electrons, location of various elements, electron energy levels, and oxidation numbers.

Eighth graders identify the types of bonds elements form. For this chemistry lesson, 8th graders represent valence electrons with dot structures. They draw and label different atoms.
