Making A Solution
Question – Can a solution created by mixing two liquids become a solid without freezing the mixture?
Hypothesis- Write your own hypothesis based on our question. BE sure to give an explanation for your hypothesis. Use APE.
Materials – ¼ cup white glue
- ¼ water
- 1/8 cup hot water
- food colouring (optional) **** 3-6 drops only!
- beakers for measuring
- 1 tablespoon Borax
- plastic cups
*** 1 tablespoon = 3 plastic teaspoon (that are NOT heaping)
1) Place paper towels over your workspace.
2) Mix together ¼ cup white glue and ¼ cup water.
3) Stir vigorously until the two substances form one solution.
4) Add 3 – 6 drops of food colouring to your mixture. Stir well.
5) In a separate container, dissolve 1 tablespoon of borax in 1/8 cup hot water. Be sure that the borax is totally dissolved before you more to the next step.
6) Stir the borax mixture and glue mixture together. You must continue to stir until the mixtures begin to glob together.
7) Take out the mixture and “work” it in your hands for 5 – 10 minutes or until the mixture becomes shiny and is no longer sticky. If the putty is still too sticky, return it to the cup and add a little more borax to stiffen the mixture.
8) Place your silly putty in a Ziplock bag.
9) Clean your workspace thoroughly.
1. What happened to the mixture after adding the Borax to the glue? Use diagrams and labels. Remember that your observation page should have a title and your drawing should be organized on the page. Be sure that the paper you are using is facing the correct way.
Conclusion – Write a conclusion for the experiment. Be sure to use your observations to support your conclusion. Also, refer to your hypothesis and whether it was right or wrong.
1. Would you consider the final product a solid, liquid or gas? Explain your thinking fully.
2. How do you know that your final product is a solution? Be sure to support your answer with information from your notes.
