Procedure:
1. Wrap the antenna of the RC car and of the receiver with the first material you want to
test, using several layers so that they are completely and securely covered.

2. Attempt to operate the RC car using the remote control. Does it work?

3. Use a stopwatch to time your test drive over a set distance.

4. Repeat steps 1 to 3 using other materials.
Make sure to maintain the distance between the RC car and the remote control.
Record all your observations and data in the table below.

Materials

• aluminium foil
• plastic wrapper
• Раper
• wax paper
• Cotton
• rubber glove
​

Answer 1

Answer:

Does the car work?

1. No

2. Yes

3. Yes

4. Yes

5. Yes

6. Yes

Explanation:

Observation

1. The aluminum interfered the transmission of control signal between the controller and the antenna

2. The plastic wrap is thin and not likely interfere with radio waves

3. Paper didn't absorb and interfere with radio waves

4.The wax paper didn't do anything about the transmission of control signal between the controller and the antenna

5. Cotton is not heavy and it's thin to not interfere with radio waves

6. Rubber glove also didn't do anything to make the RC car not work
