### Understand Measurement Equivalence Performance Task

You and a friend make a gravity-powered racer for an upcoming race.

Question 1.

The rules state that the racer must be less than 40 inches wide and less than 96 inches long. The weight of the racer must be less than 70 pounds.

a. Your racer is 2 feet wide and 1 yardlong. Does your racer meet the size requirements? Explain.

b. Your racer weighs 65 pounds without wheels, and each wheel weighs 22 ounces. Is your racer under the weight limit? Explain.

Answer:

a) one feet is equal to 12 inch

2 x 12 = 24

the required measurement is 40 inch

the racer does not met the requirments.

### Understand Measurement Equivalence STEAM Performance Task

An electrical circuit is a pathway of wires that electricity can flow through. Many homes have an electrical panel that provides power to electrical circuits. The circuits are connected to electrical outlets throughout the home.

Question 1.

Watts are the measure of how much power a circuit can provide. Every electrical current has two components: volts and amps.

Watts = volts × amps

a. For a wire that carries 120 volts and 20 amps, how many watts of power are available?

b. For a wire that carries 240 volts and 15 amps, how many watts of power are available?

Answer:

a. watts = volts x amps

120 x 20 = 2400

2400 watts of power are available

b. watts = volts x amps

240 x 15= 3600

for a wire that carries 240 v and 15 a the power of watts available are 3600.

Question 2.

An electrician checks the circuits in your house.

a. One of the circuits has a maximum capacity of 15 amps. The electrician recommends that you only use \(\frac{4}{5}\) of the total amps on the circuit. How many amps should be used?

b. The wire from this 15-amp circuit carries 120 volts. How many watts should be used on this circuit?

c. Your toaster is plugged in to the 15-amp circuit. Use the table to find another appliance that can be used on the same circuit and stay within the recommended amount of amps.

d.Can you run the microwave and the refrigerator on the15-amp circuit? Explain.

Answer:

yes by the above table recordings

Question 3.

You are decorating for a party at your house.

a. There are 15 bulbs on a string of lights. Each bulb uses 12 watts of energy. How many watts of energy does one string of lights use?

b. You connect 7 strings of lights together. Can the lights be plugged into a 15-amp circuit, or is a 20-amp circuit needed? Explain.

c. The length of each string is 20\(\frac{3}{4}\) feet. What is the total length of all 7 strings of lights?

d. Five of the bulbs burn out. Of the bulbs that are lit, \(\frac{2}{10}\)are purple, \(\frac{1}{10}\) are blue, \(\frac{2}{10}\) are green, and the rest are red.What fraction of the bulbs are red?

e. How many more bulbs are purple than blue?

f. The lights are plugged in from 4:35 P.M. until 9:35 P.M. Each hour that the lights are on costs about $0.18 in electricity.What is the total cost to have the lights on for the party?

Answer:

a. one bulb = 8 watts

one string = 15 bulbs

8 x 15 = 120 watts

b. 7 x 120 = 840 watts make an ampire 15 amp wire is enough

1 amp = 120 watt

15 amp 15 x 120 = 1800 watt capacity circuit

c. 145

d. 0.2 are purple

0.1 is blue

0.2 are red

the fraction of the bulbs are red

e. 0.1bulbs are purple than blue

f. 5 x 0.18
