We added another water bottle as a swing to make our device more complicated since we had more time.

Ideas to use Rube Goldberg machines:
- Relational Capacity machines working backwards throughout the class periods. (E.g. the end result of a balloon popping, as students finish class work they can add another step to the machine.)
- full class project
- team building beginning and/or throughout the year

We began with creating a ramp for the impact of a push to create distance for the cup to travel 15cm. We used an upside down, opened laptop as our ramp. The marker box being the object that slides down the ramp to push both cups.
For the end portion we stacked both cups on top of each other for the marker to hit. The cup on top falls from the impact of the marker box causing the cup to roll 15cm.

Knock an object off the table to pull the cup up 35cm. (pulley system)

Objects used:
2 boxes, tape, Large water bottle w/strap, 16 oz metal bottle, 16 oz plastic bottle, green solo cup, Post-it notes

We tried using markers to launch our marker at the cup but found the didn't give enough force to knock off the top cup so we improved by just using our hand to launch it.

Ideas:
-Use as a teambuilding/inquiry activity
-Use when introducing scientific method
-Use during physics/forces unit

Launch marker at stacked up cups and make top cup go further than 15cm

How can you use the Rube Goldberg challenge to spark and increase inquiry and collaboration in your class?
-This task is made specifically for inquiry and collaboration
-Can use CSG with Rube Goldberg to increase inquiry and collaboration, students can ask questions and discuss process and building
- Team building activity as celebration, maybe after the end of a hard unit

Create a ramp for water bottle to roll down to hit another bottle to hit the cup. Cup rolls 12 cm twice. Once across the table and once from table to the floor.

Accurate measuring device to prove that it went the right distance. Take the table cloth off to reduce friction. Add more force on 2 marker box push.

With the initial prototype, the table cup fell off once we dropped the highlighters in the hanging cup. We added a stop by taping a highlighter down on the table that stops the cup from falling off the table.

# data[].attributes.body
We did improve during testing. We added a highlighter to stop the can from rolling. Once the highlighter was removed, the can would roll and start moving.

Use 2 cups, tape and highlighters on the edge of the table. Long piece of tape connecting the two cups. Place one on the table, one off the edge. Drop the highlighters in the hanging cup to pull the table cup.
