Classroom Resources: Solutions

1 – 8 of 8 Classroom Resources

• 

  Colligative Properties, Boiling Point Elevation, Freezing Point Depression, Concentration, Solute & Solvent, Boiling Point, Freezing Point, Phase Changes, Molecular Motion, Graphing, Physical Properties, Heat, Temperature | Middle School, High School

  Activity: Simulation Activity: The Effect of Solutes on Boiling and Freezing Point

  In this activity, students will use a colligative properties simulation to investigate the effects of different solutes, and different amounts of those solutes, on the boiling point and freezing point of a solution. Students will see particle-level animations of boiling and freezing with different types and amounts of solutes, as well as graphical representations of the results of each trial.

• 

  Concentration, Percent Composition | Middle School, High School

  Lab: Homemade Hydrometers

  In this lesson, students will engineer simple hydrometers from straws and clay to learn about standard solutions, calibration, and instrument drift. They will use their hydrometers to test the salinity of samples of natural water.

• 

  Concentration, Physical Properties, Chemical Properties, pH | Middle School

  Activity: Would You Drink it?

  In this activity, students are provided with data regarding the water quality at multiple locations throughout a city. Students will determine which location should be prioritized for cleaning of contaminates. Students will utilize Claim Evidence and Reasoning (CER) to develop a claim that is supported by the data provided.

• 

  Concentration, Solute & Solvent | Middle School, High School

  Lesson Plan: Diffusion and Osmosis

  In this lesson, students will build upon their understanding of solutions and concentration. They will observe the diffusion of food coloring dye in water and then perform an experiment focused on how solutions of different concentrations will affect the movement of water across a semi-permeable membrane.

• 

  Concentration, Solute & Solvent, Chemical Change | Elementary School, Middle School

  Demonstration: Soft Eggs

  In this demonstration, students will first observe a reaction between vinegar (acetic acid) and an egg shell (calcium carbonate) to produce a naked egg. Using these eggs, student will analyze how certain substances can move through a membrane and also determine if the membrane is affected.

• 

  Concentration, Mixtures, Interdisciplinary, Scientific Method, Measurements | Middle School, High School

  Lab: Effect of Salt Concentration on Plants

  In this lab, students will observe how salt concentration can affect the structure of a potato tuber.

• 

  Concentration, Solute & Solvent, Mixtures, Solubility, Percent Composition | Middle School

  Lab: The Perfect Kool-Aid Concentration

  In this lab, the students will investigate how the concentration of a solution affects its properties such as color and taste.

• 

  Reaction Rate, Graphing, Temperature, Concentration | High School, Middle School

  Lab: Starch-Iodine Clock Reaction

  In this lab, students perform an iodine clock reaction to determine how concentration and temperature effect the reaction rate.
