Freezing Point Depression: Why Don’t Oceans Freeze?
Can you go ice fishing in the ocean? Learners examine the freezing point of different saltwater solutions. Each solution has a different concentration of salt. By comparing the freezing points graphically, they make conclusions about...
Curated OER
States of Matter Mini-Unit
Students identify he phases of matter (solid, liquid, gas), and why they take place. They comprehend what a physical change is and what a chemical change is. Students know the difference between a Mixture and a Solution.
Curated OER
Mixtures
In this mixtures activity, students fill in 7 blanks, determine if 4 statements are true or false, match 7 terms with the appropriate definitions, and solve 2 problems. These include topics such as homogeneous and heterogeneous mixtures,...

What is in the Water?
For this mixtures worksheet, high schoolers read about mixture and what determines if a solute dissolves in a solvent. They answer three questions about solutions and determine from a list of compounds which are soluble in water.
Curated OER
Suspensions and solutions
Students create mixtures of baking soda, baking powder, flour, and more to predict which are solutions and which are suspensions. Students follow 4 directions and answer 3 questions.

Mixing It Up!
Third graders identify the different states of matter. In this science instructional activity, 3rd graders describe the different components of solutions and mixtures. They create emulsions, foams and suspensions in the lab.
Curated OER
Solids and Water
Students investigate mixtures made of water and familiar solid materials. They observe and discuss the changes that occur immediately and set the mixtures aside for a day. Finally, students observe the mixtures, note changes, and graph...
