Scope on Safety : Essential First Aid for Science Teachers
From a practical standpoint, science teachers should be trained to respond to incidents involving burns, bleeding, chemical exposure, swallowed poisons, penetrating objects, lacerations, and shock. Basic training is required to properly handle these situations, and this training should be reviewed annually. A list of possible lab incidents and the appropriate first-aid response is provided.
The path of light
This short article uses text and illustrations to explain that light travels in a straight path until it encounters interference.
In this two-player online game, students combine math skills and strategies to practice simplifying, converting, and multiplying decimals, percentages, and fractions.
