Starter Directions: What two units is this speedometer measured in?
Speed Day 12
Essential Question • What is the relationship between speed, velocity, and acceleration?
Learning Target I can calculate speed using the KWFL chart.
Homework Day 12 Direction: On the left-side of your notebook, write the following density problems. Remember to use your triangle and KWFL chart to complete your homework. • What is the density Kool-Aid with a mass of 5 grams in a 5 milliliter container? • What is the mass of chalk with a density of 3 g/cm3 and a volume of 6 cm3? • What is the volume of an unknown liquid with a mass of 10 g and a density of 5 g/mL?
Review: Density Directions: On the left-side of you notebook, draw the KWFL chart and answer the following word problems about density. • What is the mass of a cube with a volume of 20 cm3 and a density of 2 g/cm3? • What is the volume of a liquid with a mass of 10 g and a density of 1 g/mL?

Analyze this Picture.. • Which car has the highest speed and why?
Investigation Procedure Part A: Creating Data Table • Make a data table with two columns and five rows. • Label the first row of the data table Distance and Time. Part B: Track Set-Up • On your table using a piece of tape marking the starting line. Then measure 30 cm using your ruler. Mark your finish line with a piece of tape. • Record your distance in the table you created from Part A. • At the starting line, push your object forward with an enough force to make the object cross the finish line. At the same time make sure to start your stopwatch. • When the object crosses the finish line, stop the stopwatch and record your time beside the 30 cm in your table. • Repeat steps 1-4. For 40 cm, 50 cm, and 60 cm.
Notes: SpeedWrite on the right-side of your notebook. • Speed can be calculated by dividing the distance an object travels by the time it takes to cover the distance. Formula Speed=distance s=d time t d s t Unit meters per second (m/s) or kilometers per hour (km/h).
Practice Problems: Speed Teacher Demonstration • Directions: Use a KWFL Chart to solve the word problem. A toad jumped 3 kilometer in 1 hour, then jumped 1 kilometer in 2 hours, it rested for 1 hour, and then jumped 5 kilometer in 2 hours. What was the toad’s average speed?
Practice Problems: SpeedTeacher Demonstration • Directions: Use a KWFL Chart to solve the word problem. If a frog jumps a distance of 3 meters in 6 seconds, what is its speed?
Student Volunteer Comes to the Board • Directions: Use a KWFL Chart to solve the word problem. A runner completed the 100-meter dash in 10.0 seconds. Her average speed is?
Speed: Group KWFL • Directions: Using the word problem, complete a KWFL (using poster paper). • While traveling on vacation, you measure the times and distances traveled. You travel 25 kilometers in 5 hours, followed by 25 kilometers in 5 hours. What is the average speed?
Practice Problems: Speed Directions: On the left-side of your notebook, Draw a KWFL Chart to solve the following word problems. • What is the speed of a car that travels 180 km in 1.5 hours? • What is the average speed of a dog cart that travels 2 kilometer in the first 30 min., 0.5 kilometer in the next hour and 3 kilometer in 30 min.?
3. If a car has a constant speed traveling 80 meters/hour in 5.5 hours, how far is the car traveling? 4. If you walk at a constant speed traveling 2 kilometer/second in 0.5 kilometers, how long will it take to you walk? 5. If a lion runs 40 kilometers in 120 min, how fast will he travel?
Practice Problems: Speed Students Come to the Board • What is the speed of a car that travels 180 km in 1.5 hours? • What is the average speed of a dog cart that travels 2 kilometer in the first 30 min., 0.5 kilometer in the next hour and 3 kilometer in 30 min.?
Directions: Students comes to the board to show answer. 3. If a car has a constant speed traveling 80 meters/hour in 5.5 hours, how far is the car traveling? 4. If you walk at a constant speed traveling 2 kilometer/second in 0.5 kilometers, how long will it take to you walk? 5. If a lion runs 40 kilometers in 120 min, how fast will he travel?
Exit Slip • Directions: Identify what you know “K” and what you are solving for “W” using the following word problem. A spider crawls on a wall. First it crawls 1 meter up, then 1 meter to the left, and 1 meter down in 3 minutes. How fast does the spider crawl?
