Internet: Introducing Email
Pupils discuss the use and misuse of email and identify six new technology terms. After opening a word document, they experiment with fonts and sentence writing before pasting it into their email. The lesson concludes with students...
Curated OER
So You Want to Hit a Home Run?
Students determine the center of percussion and the center of mass for a baseball bat. In this projective motion lesson students demonstrate the relationship between the position of the baseball bat and when its in the position in the...
Curated OER
Not a Drop to Drink
Students design an experiment to determine which liquid is water. For this chemistry lesson, students perform the experiment as outlined in their design. They record observation and formulate conclusion.
Curated OER
Heat from Light
Second graders explore solar energy. For this science lesson, 2nd graders use hand lenses to see that light energy can be converted to heat energy.
