<p> Are You Speeding PASCO SPARK</p><p>For this lab we are using one of the labs that are pre-loaded on SPARK. The directions for this lab will be directions on how to follow the links on the SPARK.</p><p>Turn the SPARK unit on by pressing the black button on the bottom of the unit. After it has powered on, press the Open button – choose Middle School Science and select Are You Speeding and press OK.</p><p>At the top left of the screen you will find a page number with an arrow to the right (this will take you to the next page. Press the arrow in order to move on to the next page of this lab.</p><p>Complete all questions in your lab notebook:</p><p>Page 3: Problem: What is speed and how is it related to velocity? Page 4: Using the information on page 4, work as a group to come up with a definition for velocity? Page 7: Q1 – Draw a line on the graph to predict the slope for a person walking at a slow pace. Page 8: Q2 – Draw a line on the graph to predict the slope for a person walking at a quick pace. Page 9: Q3 – Draw a two lines on the graph to predict the slopes of both people walking – both travelling the same distance but one person finishing in less time.</p><p>Page 7 Page 8 Page 9</p><p>Page 10: Follow the instructions to complete the lab Page 11 & 12: The SPARK will graph your data…copy that graph here and be sure to label your axis.
