Hard Work, Hard Core!

Science Lab Report 2015

December11

Hello and welcome everyone to my latest post and today’s topic is all about our science lab report which we have been working on for a while now all the way through term 4. I hope you enjoy reading and don’t forget to comment and follow/subscribe! So what are we waiting for? Lets release the SCIENCE!

Through-out this term(term 4), me and Jordan have been working very hard in order to complete our science experiment and make a report about it in a power-point, which will be attached in the link at the bottom of the post. The following is the exact information from that power-point, so you can choose which source to read it from.

SCIENCE EXPERIMENT

Aim:

To observe if electricity can conduct through a battery while in water (Coloured or Transparent) to produce energy to power a light bulb.

Hypothesis:

Can electricity conduct through a battery while in coloured water? Will it create the same effect as a battery under normal conditions?

Materials:

Battery, Wire, Circuit, Mug/Container, Water, Alligator Clips, Light Bulb, Food Colouring (Any Colour/Optional).

Method: 

1) žFill the container with water.

2) žClip the alligator clips onto the wire.

3) žDye the water. (Any Colour)(Optional)

ž4) Place the battery in the water filled container.

5) žPlace the light bulb onto the battery.

6ž) Place the wire on the positive side of the battery.

7) žObserve the circuit and reaction of the electricity.

OUR HYPOTHESIS WAS NOT CORRECT 🙁

Working Method:

1) žFill the container with water.

2) žClip the alligator clips onto the wire.

3) žDye the water. (Optional)

4) žPlace the light bulb onto the water

5) žMake the wire touch the light-bulb

6) žObserve the circuit and reaction of the electricity.

OUR OBSERVATIONS WHERE WRITTEN MANUALLY

🙁

DISCUSSION:

This outcome occurred because the second battery wasn’t needed and the wires weren’t insulated. The original hypothesis for this experiment determined that energy would be able to travel between a circuit and a light bulb through water.

Once water contains ions it will conduct electricity, such as from a lightning bolt or a wire from the wall socket, as the electricity from the source will seek out oppositely-charged ions in the water. This feature is put into practice in insulating wires with rubber to protect them from water and to also help them to not overheat.

Insulating wires allows electricity to be transferred through water. In our observations you can see that the submerged wires lost their electricity from being exposed in water.

CONCLUSION:

When we conducted our experiment our hypothesis was disproved partially. Because the wires weren’t insulated we couldn’t transfer the electricity to the light bulb. We found out that uninsulated wires are vulnerable to water and overheating because they aren’t protected by rubber, etc.

To follow up we might conduct a new experiment using salt water or possibly a new experiment using insulated cables.
