1. (1) (3) (2) (4) (5) Steps 4 and 5 are the steps of the EDP where we test our prototypes 1 SPI 0807.T.E.1 to 2: (Eng. Des. Process) SPI 0807.Inq.2 (Sci Tools & Procedures) SPI 0807.Inq.4 (Cause and Effect) SPI 0807.12.4 (Mass and Weight) Quick Review May 8, 2013 Use the right arrow button to advance through the presentation

2. In an experiment… …you measure things with the metric system using tools such as: Notes 2 Scientific Tools  …a triple beam balance -measures mass SPI 0807.Inq.2 (Tools and Procedures -unit of measure: grams -examples: milligrams (mg), grams (g), kilograms (kg)

3. In an experiment… …you measure things with the metric system using tools such as: Notes 3 Scientific Tools  …a metric ruler or meter stick -measures length SPI 0807.Inq.2 (Tools and Procedures -unit of measure: meters -examples: millimeter (mm), centimeter (cm), meter (m), kilometer (km)

4. Engagement: Have you ever seen cars race? What makes some cars go faster than others? Would a heavier/more massive car go faster or slower than a car with less mass? Now imagine cars racing downhill. Would being heavier/more massive be an advantage or disadvantage in this situation? Today we will find out.

5. Materials: 1 lab journal sheet per student (pass them out) 11 work stations 1 triple-beam balance per work station 5 ramps Numerous meter sticks 1 Lego kit per work station 1 weight per work station 1 Lego booklet per work station Notes 5 SPI 0807.T.E.1 to 2: (Eng. Des. Process) SPI 0807.Inq.2 (Sci Tools & Procedures) SPI 0807.Inq.4 (Cause and Effect) SPI 0807.12.4 (Mass and Weight)

6. Activity:  Construct a 4-wheel Lego car per page 10 of the booklet  Measure the mass of the black weight  Measure the mass of the car (without the weight)  See how far the car rolls without the weight  See how far the car rolls with the weight  Complete the journal work sheet (see other image on screen)  Start with your prediction Notes 6 SPI 0807.T.E.1 to 2: (Eng.
