Students will be able to calculate speed using the cars that they made in a previous lesson.
Duration: 1 class period ( 85 minutes )
Middle School (ages 11-13)
MODULES & ACCESSORIES USED (3)
dc motor (1)
OTHER MATERIALS USED (3)
STEP 1 : Connect
Review velocity from previous day.
STEP 2 : Engage
Use cars built from previous day. Have students gather data on their cars. Use a set distance and measure the time it takes for the car to travel that distance. I recommend 1 meter. (refer to student handout below)
STEP 3 : Teach
Average speed = distance / time Show students how to calculate the speed. If necessary allow students to use calculators. Review vocabulary numerator and denominator. Have students calculate the speed from their data. Complete student notes together as a class.
STEP 4 : Practice
Use whiteboards, plickers, or whatever is comfortable. Give students various problems to solve and check to see if students are successful. Re-teach if necessary. Practice problems attached in handouts.
STEP 5 : Close
Calculate speed on worksheet.
