Fetch, Dog, Fetch is an engineering and design challenge that supports Next Generation Science Standards K-2 ETS1 and 3-5 ETS1. It is designed for students in 1st through 6th grade. The lesson can be differentiated based upon students' grade and maturity or skill levels.
Typically taking 3-4 class periods students will learn about the background to the problem (some dogs like to play fetch A LOT), they will investigate ideas to help them to create a tool or machine that assists in launching balls for dogs to chase (resources are included to view and discuss some ideas/tools), students will work in groups to brainstorm and sketch their ideas, they will construct a tool or machine to act as a ball launcher, they will measure and graph results, critically review results, and summarize the activity.
This packet includes detailed teacher instructions that are easy to follow, a letter to parents describing what you are doing and how they might help, photo slides to use during instruction (both with a background story and pictures of some tools to consider when designing a ball launcher), and student pages to use in an interactive journal.
The background story includes dog pictures that I took when we played "Fetch."
Additional support for this engineering challenge can be found on my blog http://sci-fries.blogspot.com/. Additional videos will be posted there to give ideas and background knowledge to the teacher.
