Classroom Resources: Solutions

1 – 6 of 6 Classroom Resources

• 

  Physical Properties, Concentration, 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.

• 

  Mixtures, Interdisciplinary, Concentration, Measurements, Scientific Method | 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, Reaction Rate, Temperature, Graphing | 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.

• 

  Mixtures, Solubility, Percent Composition, Concentration, Solute & Solvent | 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.
