To make a simple electric circuit, you need:

1) 1 light bulb - to test that the simple electric wire works

2) 1 light bulb holder - to hold the light bulb while it's being lit up

3) 2 pieces of 20 centimeter long insulated wires

4) 2 batteries - (battery type depends on the type of battery pack you get)

5) 1 battery pack - (The type of batteries depend on the type of battery pack you get.)

6) 1 roll of electric tape - while connecting the wires, you must make sure no electrical current comes out, so we use a special type of tape to keep safe.

7) 1 wire stripper (or pair of scissors) - You have to expose the wires by stripping them in order for the circuit to work.

8) 1 screwdriver - to loosen and fasten the screws on the light bulb holder.

1) String the fishing line between two objects about 80 to 100 feet (24 to 30.5 meters) apart. Before attaching the 2nd end of the line, thread the line through 2 of the straw pieces, in a way that they can slide on the line
2) Cut off both the water bottle ends so you have a 3-4 inch (7-10 cm) ring
3)Take the ring and tape it to one of the straw pieces
4) Blow up a balloon and hold it to the ring, whilst putting a second balloon in place so that it stops the air escape from the 1st balloon

1. Be cautious when holding the glue gun because it can burn your hand, arm, leg, etc.
2. Do NOT aim the catapult at someone.
3. Do not play with the rubber bands as a catapult.

Make sure that you do not stand/lean in front of the balloon while it is moving along the string as this could hurt.
Be careful when cutting the plastic bottle as you could cut yourself.

1. Cut out the waxed cardboard to match the diagram in Figure 3.13.
2. Put the rubber band around the propeller and attach it to the boat using butterfly pins.
3. Wind the propeller anticlockwise, place the boat in the water and release it.

# data[].attributes.body
Use your hand to turn the rubber band on the propeller in one direction. Tighten the rubber band constantly, then put the boat on the water and let it go. Because of the rebound of rubber band, so it moves the propellers. And the boat will start moving on the water.
The energy that Rubber band boat stored is strain energy, it turns to movement energy. And the waste energy is sound energy.

When making measurements, form the habit of using only one hand at a time.

do not touch the circuit with wet hands(water is a good conductor of electricity).

A circuit is a closed path that electrons flow along.[1] A simple electric circuit contains a power source (battery), wires, and a resistor (light bulb).[2] In a circuit, electrons flow from the battery, through the wires, and into the light bulb. When the bulb receives enough of these electrons it will light up. When constructed properly, you will be able to light your bulb with just a few simple steps.

6. Most of the potential energy given to the balloon is used to propel it forwards using mechanical energy, but some of it is wasted as sound energy and heat energy due to friction.

We tie the fat rubberband to the wooden crotch, use small rubberbands to secure and stable the big rubberband on the crotch.

There is chemical energy stored in the battery. When the battery powers the light bulb, it is converted to light, heat and electrical energy. You can see the light come out of the bulb, and you can feel the heat from the bulb.

# data[].attributes.body
The Energy in this experiment is transferd from strain potential energy when you pull back the rubber band. When you let go it is kinetic enrgy( moving) when the stone or loaded fires away. It will make a slight sound.
