- 5. Glaak Today youwill be making a new substance called Glaak. You will make it by combining materials that will result in a new material. This is what it should look like in the end.
- 6. How do theylook? Looking at all of the ingredients in front of you describe their properties. Write your answers in your science journal. Salt, Starch, and Glue. Draw a picture detailing what they each look like.
- 7. How to makeit Ingredients: 125 ml liquid laundry starch 62.5 ml white all-purpose glue 2.5 ml salt Combine the starch with the salt and stir until the salt is dissolved. Next, add the glue and stir until a lump of Glaak forms.
- 8. Questions Answer thefollowing questions in your science journal. What has happened to the properties of each ingredient? Does the Glaak have the same properties of the original ingredients? How would you describe the Glaak? Why did the properties of the ingredients change? Now you can play with your Glaak!
