Refraction

Investigating Refraction - Bending Light

Aim: To investigate how light is affected by changing the substance it is traveling through.
Equipment: Ray box, power source, glass or perspex block, single-still ray slide.
Method: Collect the equipment, and set them up to produce a single beam of light.

Part A: Going from air to Glass

1. Place the glass block in the shaded area below.

2. Place your ray box at the top of the page and shine the beam so it travels along the 10° line to the centre of the protractor (this is your angle of incidence, i°).

3. Read the angle the light leaves the glass block at (this is your angle of refraction r°).

4. Continue the investigation so you can complete the table opposite.

Results:

Angle of Incidence (i°)	Angle of Refraction (r°)
10°	6.6°
20°	13.2°
30°	19.5°
40°	25.4°

Charlie Bone and the Red Knight

Charlie Bone and the Red Knight

Charlie Bone is a series of eight children fantasy school and adventure novels written by Jenny Nimmo. Charlie Bone and the Red Knight was published on October of 2009.

The book is about the evil Bloors collecting even more powerful and magical allies. These allies are just sinister whispers and shadow but later on, these allies are daylight robbers and descendants of Count Harken. The cronies are taking over the city and driving everyone away. Charlie is determined to stop them. However, with the Pets Cafe closed, Billy trapped in Badlock, and Olivia "taken over," it looks like Charlie's only hope is the mysterious Red Knight. In the meantime, Charlie and his friends are searching for a will that reveals everything including who really owns Bloor's Academy. Paton believes the Raven family rightfully owns it which means Billy could inherit the academy if the will can be found. However, Charlie is in for a surprise when the will is revealed. The Red Knight is revealed to be none other than Lyell Bone himself, who wanted to watch his son near to him, but in a disguise. The will is hidden in the church where Lyell played, and the academy is owned by the Bones. Manfred and Ezekiel die in a freak accident, and Dr. Bloor moves away, he moves to paris, where his wife lives, with all the evil people in the city. Bloor's becomes Bone Academy, and is proclaimed the happiest school in the city. Billy is adopted by Lyell and Amy, Paton and Julia marry, and they move together to the bookstore. The book ends when Billy whispers to Charlie at the Pet's Cafe, "Tancred and Emma are holding hands."

Particle Theory of Matter - Convection

Observing Convection 1

Aim: To observe convection in a liquid.

Equipment: 200 ml beaker, water, tweezers, a crystal of potassium permanganate, a drinking srtaw, Bunsen burner, heat mat, tripod and gauze mat.

Method:

1. Set up a bunsen burner on a heatproof mat. Put the gauze mat on the tripod but leave it just to one side of the Bunsen burner.
2. Fill 200 ml beaker with 150 ml cold water.
3. Place the beaker on top of the tripod and gauze and allow it to settle for a few minutes.
4.  Carefully insert a drinking straw down one side of the beaker, ensuring the straw is touching the bottom of the beaker. Be careful as you don't want to disturb the water too much.
5. Using tweezers, drop a crystal potassium permanganate down the inside of the straw. Wait for the crystal to settle on the bottom of the beaker.
6. Very gently, so to not disturb the water, remove the traw.
7. Light the Bunsen burner and slide it under the tripod so that you are only heating the outside of the beaker where the crystal is. Observe.

Particle Theory of Matter - Conduction

The Dropping pins Experiment

Aim: To observe conduction along a metal rod.

Equipment: A metal rod, retort stand and clamp, Bunsen burner, petroleum jelly, 5-10 drawing pins, a stopwatch.

Method:
1. Set up and light a bunsen burner.
2. Smear a small amount of petroleum jelly on to the head of each drawing pin.
3. Attach the drawing pins at even intervals along the length of the metal rod.
4. Clamp one end of the metal rod to a retort stand.
5. Position the retort stand so the unclamped end of the metal rod is in the bunsen flame and start the stopwatch.
6. Record the time it takes for each pin to drop in the table below.

Pin Number	Time to Drop
1	1min. 13sec.
2	4min. 24sec.
3	6min. 25sec.
4	8min. 24sec.
5	10min. 31sec

Behaviour of matter - Expansion

When particles are heated, they begin to move around more and the space between the particles increases, causing the substance to expand. The diagram below shows the effect of heat on the particles in a solid substance. Notice that the  particles are vibrating more. Because of this, they are bumping into each other and the distance between the particles increases. This means the solid will expand.

Describe the effects of heat on:

1.The movement of particles
2.The size of the particles
3.The space between the particles
4.The size of the substance

The Imploding Can

Aim: To observe contraction in gases.

Equipment: Aluminium can, scissor tongs, Bunsen burner, Heat Proof mat, tripod, gauze mat, an open container of water.

Method:

1. Set up a bunsen burner underneath a tripod and gauze mat.
2. Pour approximately 50-60 ml of water into your can. it should be more than 1/4 full.
3. Heat the can of water until steam is seen escaping from the top. Carefully grip the can with the scissor tongs. Ensure you have a firm hold of the can before lifting it off the gauze mat.
4. Quickly, but very carefully, invert the can as you plunge it into a container of water.
