Is It Safe To Go In?
Students examine acceptable levels of toxins in swimming areas. Working in groups of four, students dilute a salt or sugar solution to 1 part per 1,000,000 (ppm) solution. Students taste test their diluted liquids and record at which...
Curated OER
Testing for Conductivity
Students test the conductivity of selected liquids and solids. They test the circuit by touching the two free ends of the wires together and add salt little by little recording the data after each addition. Finally, students predict...
Curated OER
Sink or Float?
Students predict and explore to discover which objects sink or float in fresh and salt water, predict how salt affect objects, write predictions on T chart, discuss difference between man-made and natural waters, and graph results.
