Kool-Aid Solubility Lab
This Kool-Aid Solubility Lab activity demonstrates the relationship between the temperature of a solvent affects (water) and the amount of solute (Kool-Aid) that can be dissolved using a real-world/familiar context. It is most appropriately carried out as pairs or groups of 3 students. Tang or other powdered drink can be substituted for Kool-Aid.
This activity also enables students to practice key lab skills such as following a basic scientific method, working in groups, measuring substances accurately using relevant equipment and units, and recording and processing data.
- Students should be discouraged from drinking the used Kool-Aid at the end of the activity, due to possible contamination from lab equipment.
- Limit hot water temperature to 50oC to prevent serious burns in the event of scalding. Review the processes with students around using of hot water and its ability to cause scalding. Ensure students know the procedures in place for treatment of scalds.
Kool-Aid Solubility Lab Materials you will need:
- Kool-Aid Solubility Lab Worksheets:
- 2 x 100mL beakers
- Measuring cylinder
- Electronic balance
- Plastic Petri dish
- Stirring rod
- Hot and cold-water source.
Kool-Aid Solubility Lab Procedure:
- Ensure all equipment is clean and dry.
- Measure 100ml of cold water with a measuring cylinder and transfer it to a beaker.
- Measure the temperature of water with the thermometer and record this value in the results table.
- Use the electronic balance and tare the Petri dish before weighing out 5g of Kool-Aid into the plastic Petri dish.
- Transfer the Kool-Aid to the beaker of cold water and stir it until the Kool-Aid has dissolved.
- Continue to measure and then add Kool-Aid to the beaker of cold water in 5g increments until no more can be dissolved.
- Record the final mass of Kool-Aid in the table.
- Repeat the activity with 4 other temperatures by mixing hot and cold water in a beaker to achieve each temperature and then measuring out the 100ml volume.
The Solubility Activity:
Students record their predictions and results of the lab activity. Once the activity is finished, discuss the lab activity and answer post-lab questions.
We also provided some of the Resources below for you to use in class. iTeachly Members can access all the content for the activity and the following lesson.
Students must come up with a unanimous answer for each question. Discussing the answers usually, results in some excellent dialogue on this topic.
