5. Procedures
1st Activity: What is Light Sensor Cubelet and Speaker Actor Cubelet?
1. Introduction:
- If we attach a light sensor and a sound actor to a power Cubelet, the sensor will absorb light and the actor will produce a sound.
2. Make a prediction.
- Do you think the amount of light will make a difference in how frequent sound is?
3. Test it out and record the results.
- Put light sensor Cubelet and speaker actor Cubelet to power Cubelet.
- Turn the switch on the power Cubelet. How does a light sensor respond to infrequent sound? Check!
- Block the light sensor to block all the lights. How does a light sensor respond to infrequent sound? Check!
- Open the box little bit to shine a light a little bit. How does a light sensor respond to frequent sound? Check!
4. Learn about the relationship between the amount of light and light sensor.
- What is the relationship between the amount of light and light sensor?
2nd Activity: What is Distance Sensor Cubelet and Bar Graph Actor Cubelet?
1. Make a prediction.
Do you think if you put the woodblock at different distances (each 10cm apart) will the bar graph make differently? (Yes or No)
2. Test it out.
- Put the distance sensor at the line of yellow.
- Put a wood block at each 10 cm and count the bars in the bar graph Cubelet.
3. Record the results.
- Color the number of bars at each point (10cm, 20cm, 30cm, …80cm)
- How does the distance sensor work? What is the relationship of distance between the object sensor and woodblock?

- How does the distance sensor work? What is the relationship of distance between the object sensor and woodblock?
- What is the name of this sensor?
- What is the name of this actor?
- How does these sensor and actor work?
- How does these sensor and actor work?
