Welcome to Gateway to Technology - Science of Technology - Periods 1 and 7

Tech Plan for Week of March 28 - April 1 (Week 2)

This week we begin a two week project build of our Rube Goldberg energy conservation activity which is an overly complex system of interconnected mechanisms designed to perform a simple task (like dropping a piano on Mr. Wheeler). There will be a very short briefing lesson at the beginning of each class introducing sample builds of potential simple and compound machines, followed by a 30-40 minute block of time for groups to plan and construct their devices.

What is the main idea:
OBJECTIVE
Students will learn background and procedures necessary to successfully construct a "cool" RGD.
Students will learn the difference between potential and Kinietic energy and that a variety of energy sources can be utilized in their device
Students will learn that the direction of applied forces can be changed using levers and pulleys.
Students will learn that they can lessen the effort to move loads using their levers and pulleys
Students will learn the difference between Archimedes and Gravity screws.
What students will learn:
ACTIVITY
Working in small groups students will plan the the construction of their RGD and start accummulating the necessary materials.
Students will construct their space frame tower and discuss the role gravity can play as an energy source in their device.
Students will construct a simple lever and conuterweighted pulley system that could be used in their RGD.
Students will construct a mousetrap lever and pulley system to unleash the portential of the spring.
Students will construct a gravity screw and an Archimedes screw that could be used in the RGD.
What students will do:
RESOURCES
WMS-GTT-SOT, copy of planning document, financial planner, and scoring rubric.
WMS-GTT-SOT, 18 1x1x3 RGD space frame kits, access to power drills, phillips head screwdrivers, and clamps.
WMS-GTT-SOT, 10 ft of string per team, old battery counterweights, pulley, lever, and fulcrum materials
WMS-GTT-SOT, 1 mousetrap per team, kabob skewers, twist ties, hot melt glue
WMS-GTT-SOT, dowel rod, old spiral NB spine, 120 lb notecard paper with 4 inch circles, pclips
What students will need:
ASSESSMENT
Groups will present a rough draft of their planning document compared against the RGD rubric for 10 performance points.
Students progress on their team RGB build will be assessed on a 5 point build quality and a 5 pt performance rubric.
Students progress on their team RGB build will be assessed on a 5 point build quality and a 5 pt performance rubric.
Students progress on their team RGB build will be assessed on a 5 point build quality and a 5 pt performance rubric.
Students progress on their team RGB build will be assessed on a 5 point build quality and a 5 pt
How students will show they know:
