Curated OER
Mixtures as Solutions or Colloids and the Tyndall Effect
Students classify mixtures as solution or colloids by virtue of the Tyndall Effect. They make a cone and tape to fit over the lens of the flashlight. They turn out the lights in the room and shine the flash light at each of the jars and...
Curated OER
Turbidy and Water
Students use observation skills in assessing the water quality of water samples in this activity and learn that the tastes and preferences of others can be different.
