TOC: Bubble Gum Physics 1-23-12 I STARTER: It is important that we be able to convert time from days to hours to minutes to seconds. Make the below conversions and show your work! 1. Convert 7 days into hours. 2. Convert 8 ½ hours into minutes. 3. Convert 1 hour 45 min’s into seconds. II PRACTICE: Bubble Gum Physics Lab Glue in Bubble Gum Physics lab and complete. III APPLICATION: • Insert notes on graphing and complete graph from Bubble Gum Physics Lab data. Variables • Variables are factors, conditions, and/or relationships that can change or be changed. (Growing plants with different amounts of water.) Independent Variable • a factor or condition that is changed on purpose. (Different amounts of water). [ON THE HORIZONTAL AXIS]. Dependent Variable • a factor that might be affected as a result of the change in the independent variable. – Example(Height of plants depending upon how much water the plant received.) [ON THE VERTICAL AXIS] Controlled variable • a factor that is not changed. (Same soil and same amount of light each day.) • Data is the information collected from observations. • Bar graphs are used to compare information about similar things. • Line graphs are in which line segments are connected to show changes that occur, often over a period of time. • An interval, increment, or scale is the increase in size or number. • The horizontal axis is found on the bottom of the graph and is used to show the manipulated variable. • The vertical axis is found on the side of the graph and is used to show the responding variable. 5 10 15 20 25 30 35 40 45 50 Distance (m) Graphing Activity 0 1 2 3 4 5 6 7 8 9 10 Time (s) IV CONNECTION: Put into place a plan using speed, time, and distance calculations for a road trip. This road trip will be a total of 75 miles and you will be able to keep a steady 70 miles per hour You will also need to factor in 2 stops that will add on an additional 5 minutes each. Show your math to calculate how long the trip will take and tell what time grandma should expect you to arrive if you leave at 8:00 am. V EXIT: • Write a well written paragraph (5 sentences!) summarizing what you learned today. Also, list any questions you may still have about Speed, Time, & Distance.
