Curated OER
Classifying Matter
Details about matter and how it is classified are included here. The slides, with differences about homogenous and heterogeneous mixtures, have diagrams to support the definitions and your class will appreciate the summaries to assist...
Curated OER
Mixtures Lab
Students classify different mixtures. In this mixtures lesson plan, students determine samples to be suspensions, colloids, or solutions and compare homogeneous and heterogeneous mixtures.
Curated OER
Solutions, Suspensions, & Colloids Lab
In this solutions, suspension and colloid activity, students complete a lab experiment in order to determine if a given mixture is a solution, suspension or colloid. They are given six vials and they record their observations of each and...
Curated OER
Solutions, Suspensions, and Colloids
In this solutions, suspension, and colloids worksheet, middle schoolers answer questions as it relates to their reading information about solutions, suspensions, and colloids. Students observe different examples and complete a chart as...
Curated OER
Water Unit
In this water worksheet, students review the properties of water including the density, boiling point, and evaporation. Students define mixture, solute, and solvent. This worksheet has 22 short answer questions.
Curated OER
Mixtures
In this mixtures pre-lab worksheet, students compare and contrast suspensions and colloids and solutions and colloids. Students describe the Tyndall effect. This worksheet has 10 short answer questions.
Curated OER
Water Testing
In this water testing pre-lab activity, students describe positive ions, precipitate, and the Tyndall effect. This activity has 14 short answer questions.
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.
