Makey Makey Lesson 7

What are the materials required to design a Smart Measuring Cup with Makey Makey?

• Glass, Makey Makey kit, water, computer or laptop, programming software

• Wood, Makey Makey kit, paint, computer mouse, programming software

• Plastic, Makey Makey kit, paper, smartphone, coding app

• Metal, Makey Makey kit, fabric, tablet, design software

What acts as a conductor in the project?

• Glass

• Aligator wires

• Water

• Ground Wire

Explain the role of sensors in the design of a Smart Measuring Cup?

• Sensors are responsible for changing the color of the glass based on the liquid inside.

• Sensors detect the level of liquid in the glass and convert it into speech.

• Sensors are used to play music when the glass is filled with liquid.

• Sensors help in keeping the glass clean and free from dust.

Explain the process of programming Makey Makey to produce speech.

• Connect Makey Makey to a lamp, program desired speech to specific keys, use a metal spoon to trigger speech

• Connect Makey Makey to a computer, program desired speech to specific keys, use conductive materials to trigger speech

• Connect Makey Makey to a banana, program desired speech to specific keys, use a pencil to trigger speech

• Record sounds and add to the code

Your Smart Mesuring cup is not working properly what can be the reasons ?

• Ground or Earth wire is not connected

• Circuit is open

• Water is not touching the wires

• All of the above

How does water act as a conductor in circuits?

• Water molecules break down into ions that carry electric current

• Water evaporates and leaves behind conductive particles

• Water absorbs electricity and releases it in the circuit

• Water has no role in conducting electricity in circuits

Which of the following liquids has the highest conductivity?

• Distilled water

• Saltwater

• Vegetable oil

• Milk

Which of the following liquids has the lowest conductivity?

• Saltwater

• Lemon juice

• Distilled water

• Vinegar

How does the temperature of water affect its conductivity?

• Higher temperature increases conductivity

• Higher temperature decreases conductivity

• Temperature has no effect on conductivity

• Temperature makes water non-conductive

Which of the following factors does not affect water conductivity?

• Salinity

• Temperature

• Pressure

• Color
