Over the course of the one month attachment at Science Centre, we carried out many experiments on Makey Makey and created many cool gadgets!

Here is a mini brochure of what we had done and how to create these gadgets as well!

Makey Makey Ideas

We also tried out many experiments to learn more about Science. Here is a compilation of experiments we have tried out! The miscellaneous experiments can be found in the word document at the bottom of this page.

Experiments:

1) Aluminum-air battery experiment (different versions) 

Time required: 40 minutes

Difficulty: Medium

Materials:

1.     5 plastic sheets

2.     Activated carbon

3.     Aluminum foil

4.     Vinegar/NaCl (Table salt)

5.     15 copper wires

6.     Ammeter

7.     10 paper napkins

8.     Sand paper

Steps:

1.     Prepare a square piece of aluminum foil

2.     Remove the layer of oxide on the aluminum foil using the sand paper

3.     Place a piece of napkin over the aluminum foil

4.     Prepare NaCl solution (alternatively, vinegar solution)

5.     Pour NaCl solution over the napkin (ensure that napkin is completely moist)

6.     Grind charcoal/activated carbon to powder form

7.     Layer the napkin with powdered charcoal/carbon (ensure that the charcoal/activated carbon does not have any contact with the aluminum foil)

8.     Transfer the set up onto a plastic sheet

9.     Repeat step 1-9 four times

10. Stack the individual set ups, allowing the plastic sheets to act as dividers

11. Connect one copper wire to the aluminum foil and another to the layer of activated carbon. Ensure that the copper wires do not make contact

12.  Connect the aluminum end of the first set up to the negative end of the ammeter via the copper wire

13. Connect the carbon end of the first setup to the aluminum end of the second set up via the copper wire

14.  Connect the aluminum end of the second set up to the carbon end of the second set up via the copper wire

15.  Repeat the connection for all remaining set ups

16.  Connect the carbon end of the final set to the positive end of the ammeter via the copper wire

17.  Observe the ammeter for voltage (~1.5 volts)

Aluminium-air battery

2) Paper Circuit Board

Time required: 10 minutes

Difficulty: Low

Materials:

1.     Lead pencil

2.     4 copper wires

3.     1 LED (Light-emitting diode)

4.     Battery case

5.     1 AAA battery

6.     1 A4 sheet of paper

Steps:

1.     Outline a circuit on the piece of A4 paper. Ensure that the start and end of the drawn circuit if at the edge of the paper. (Leave an area of separation in the circuit for the LED)

2.     Shade the circuit with the lead pencil. Ensure shading is thick.

3.     Connect the copper wires at edge of the paper where the end and start of the circuit is located

4.     Insert the battery into the battery casing

5.     Connect the ends of the copper wires to the battery casing

6.     Connect the LED to the lead drawn circuit (area of separation)

7.     Observe glowing LED

3) Instant Freeze

Time required: 2-3 hours

Difficulty: High

Materials:

1.     Plastic water bottle

2.     Water

3.     Refrigerator

4.     Thermometer

Steps:

1.     Fill plastic bottle with water

2.     Place plastic bottle into the refrigerator for 2-3 hours. Check bottle every half hour top ensure that the water does not freeze.  Do not irritate water in bottle.

3.     When thermometer shows water at 0 degrees Celsius whilst water is still in liquid state, remove bottle from the refrigerator.

4.     Irritate water molecules by hitting bottle.

5.     Observe crystallization of water molecules

6.     Go “WOW!”

4) Leyden Jar

Time: 30 minutes

Difficulty: Medium

Materials:

1.     Plastic bottle with a bottle cap

2.     Metal chain

3.     Woolen cloth

4.     PVC pipe

5.     Metal knob

6.     Aluminum foil

7.     NaCl (table salt)

8.     Water

Steps:

1.     Prepare NaCl solution and pour into plastic bottle

2.     Drill a hole on the bottle cap

3.     Insert metal knob into the hole

4.     On the inner portion of the bottle cap, attach the metal chain onto the metal knob

5.     Insert cap set up into bottle

6.     Wrap bottle with aluminum foil. Create a smooth aluminum surface

7.     Charge the PVC pipe by rubbing the PVC pipe with the woolen cloth in a up/down fashion

8.     Whilst rubbing, bring the PVC pipe near the metal knob

9.     Observe spark

10. Touch aluminum foil to experience “shock” sensation

5) Cartesian Diver

Time: 5 minutes

Difficulty: Low

Materials:

1.     Plastic bottle

2.     Sauce sachet

3.     Water/NaCl solution

Steps:

1.     Prepare NaCl solution and fill bottle to the brim

2.     Insert sauce sachet into the bottle

3.     Seal bottle tightly

4.     Squeeze bottle and observe Cartesian diver effect

Alternative:

1.     Prepare NaCl solution and fill bottle to the brim

2.     Insert pen cap into bottle. Ensure that pen cap stays upright

3.     Seal bottle tightly

4.     Squeeze bottle and observe Cartesian diver effect
