Zoology Word Search Puzzle
In this literacy worksheet, students practice looking for the words that are related to the idea that is focused upon in the sheet. The skill of spelling is used and vocabulary increases.
National High Magnetic Field Laboratory
Magnet Academy: Torsion Balance
Experiment with the torsion balance and see what happens first by giving the rod a charge, and then by moving the charged rod closer to the outer metal sphere of the instrument. Observe what happens to the needle as the charge increases.
National High Magnetic Field Laboratory
Magnet Academy: Torsion Balance 1785
Read about Charles Augustin de Coulomb, who didn't invent the torsion balance, but was the first to discover it could be used to measure electrical charge- the first device capable of such a feat.
