Carmen Loewen Mer Marghetti SCED 320 Nutty Putty Lesson Plan Objective: To make nutty putty, a substance that isn't clearly liquid or solid PLO’s : Describe properties of materials, including colour, shape, size, and weight For grade 2: Identify the properties of solids, liquids, and gasses For grade 7: Conduct investigations into properties of matter Introduction: The glue is a very thick and sticky substance called a colloid. In a colloid the molecules are formed into long chains, so that the substance is all tangled like a bowl of spaghetti. Borax links to water molecules, which are part of the long colloidal chains, so that the chains become joined at many points. The substance will still flow, but forces cause the long stringy molecules to tighten up, allowing nutty putty to bounce. This is an excellent, simple explanation as to the science behind nutty putty. Materials: There are some possible improvements to the original lesson plan: The given materials are too detailed and we discovered that the nutty putty could be created in a simpler way, with only: School glue Borax Water Food coloring Small paper cup Popsicle stick Procedure: Although the procedures in the original lesson plan were pretty straight forward, we formulated them in a step by step fashion that is even simpler to understand. 1. in a cup A combined 1 tsp borax and 1 c warm water 2. mix until dissolved 3. in cup B, mix ¼c white glue with 1 tbsp water and drop of food dye 4. mix together well 5. pour 1 tsp of cup A into cup B and mix vigorously with popsicle stick until a clump forms (usually onto the popsicle stick) 6. Remove clump from solution and knead in hands quickly 7. Kneading will help nutty putty to form Nutty Putty Data and Observations: 1. Original Nutty Putty Does the putty bounce? Does it stretch or flow? Is the nutty putty a solid or a liquid? Why? 2. Nutty Putty Altered 1: Repeat experiment, but add 2 tsp borax instead of just 1 tsp. (Adaptation: The amount of water can also be increased) Predict your results: Nutty Putty Nutty Putty extra borax Does the putty bounce? Does it stretch or flow? Is the nutty putty a solid or a liquid? Why? 3. Nutty Putty Altered 2: Repeat experiment, but add 3 tsp borax instead of just 2 tsp. Predict your results: Nutty Putty Nutty Putty extra borax Does the putty bounce? Does it stretch or flow? Is the nutty putty a solid or a liquid? Why? Conclusion: This lesson could, and should definitely be taught because it creates an environment for hands on learning. The lesson is very easy to understand and the nutty putty is fun to create. The students will learn that it is possible for something to be both a solid and a liquid. They will also learn to predict and compare their results from the “wrong” experiments to the original nutty putty experiment.
