Materials Change | Bend, Twist, Stretch (Science Experiments through Stories)

**What will my students learn from this activity?

This resource has been designed for teachers who want to show their students learn that everyday materials can be physically changed in a variety of ways (ACSSU018). As they move through this re-imagined story of Goldilocks, your students will investigate how objects made from different materials can be physically changed by bending, twisting and stretching.

**How do I use this resource with my students?

This project has been inspired by the story of Goldilocks. As students move through the book with their teacher, they will help Goldilocks complete a number of tasks that require them to think like a scientist. Before delivering this lesson to your students, you will need to undertake the following steps:

• print a copy of this booklet for every student in the class
• gather materials that can be twisted for your students to manipulate
• gather materials that can be bent for your students to manipulate
• gather materials that can be squashed for your students to manipulate
• gather materials that can be stretched for your students to manipulate
• For the purposes of this activity, I would recommend pipe cleaners, rubber bands, paper clips, plastic rulers, play dough, foam balls, cling wrap and Lycra.

**What will my students do as they work through this activity:

Your students will:

• Compare two materials that can be twisted and decide which one would work best in a given scenario (page 3-4);
• Compare two materials that can be bent and decide which one would work best in a given scenario (page 5-6);
• Compare two materials that can be squashed and decide which one would work best in a given scenario (page 7-8); and
• Compare two materials that can be stretched and decide which one would work best in a given scenario (page 9-10).**
