Ever wonder why some things are made from the materials the way they are? In this unit, students will plan and conduct an investigation to interpret the usefulness of materials based on their observable characteristics and properties. Student teams will classify and sort upcycled materials, communicate their reasoning for their arrangements, and be able to demonstrate their understanding of observable properties and suitable uses for the materials (observations could include color, texture, hardness, and flexibility. Patterns could include the similar properties that different materials share). Within the criteria and constraints of the unit, in the Design Challenge students will create a sign from well-curated materials to communicate a school based need.
- Students will identify with different kinds of materials that have different properties.
- Students will describe and classify different kinds of materials by their observable properties.
- Student teams will collaboratively develop an investigation plan and collect evidence including the properties of materials (e.g., color, texture, hardness, flexibility) of the materials that would allow for classification.
- Students will describe evidence about the properties of different kinds of materials and that observable patterns in the properties of materials provide evidence to classify the different kinds of materials.
- Student teams will decide how the properties of the materials will be determined, and how the materials will be classified (i.e., sorted).
- Student teams will collaboratively collect and record data on Maker Journal Pages to communicate about the properties of the materials.
In the empathy phase of lesson 1, students investigate and sort up-cycled materials into groupings of their own choosing and think of applications for those materials based on their properties. (NGSS 2-PS1-1) In the define phase of lesson 2 student teams communicate their material arrangements to each other and the reasoning behind their groupings. (MATH.2.MD.D.10) The define phase of lesson 3 demonstrates student further understanding of observable properties such as waterproof, durability of the materials under weather conditions and environmental factors. (ELA.W.2.8, NGSS 2-PS1-1) All these lessons are taken into consideration in the final Design Challenge (Ideate, Prototype, and Test phases) of lesson 4 where student teams design a sign made from well-curated materials to communicate a school based need. (NGSS 2-PS1-2)
