2. You may use only the supplies chosen by your team
You may use only the supplies chosen by your team. You may also use rulers and scissors.
You will choose from several materials to build a frame for the device.
After building the frame, strings and marbles will be attached. The strings and marbles need to hang evenly.
If your team opts to use hot glue all safety rules must be followed.
Testing your device will take place as you work and adjustments made as needed.
Your final device will be shared with the entire group.

4. Personal Description Team Description
I worked with my team to determine the best idea for the frame of the cradle and how to attach the marbles and string. I sketched and labeled my idea.
As we were building the cradle I had this job: ______________________________________________________________
I helped with solving problems when we attached the marbles and strings.
I took part in the final presentation with my team when we shared our completed Newton’s Cradle.
Team Description
Our team worked together and we decided on a great plan for the cradle frame and how to attach the strings and marbles.
Team members all had a job and we worked together. We shared the duties and treated everyone with respect.
We followed the constraints of the task and we also followed all the safety rules with the materials.
Our Newton’s Cradle was successful. We solved problems and completed the task. This includes working together as a team.
