Creating an Imitation Rainbow Spectrum

Mr. Rees — Mon, 21 May 2012 05:29:37 +0000

In class we created an Imitation Rainbow Spectrum using just the primary colours RED, YELLOWand BLUE. We could have done this using paint but it is very limited, unless you spend a lot of time with the creation. A far more impressive spectrum can be created following this procedure.

Goal: Creating an Imitation Rainbow Spectrum

Things we need:

Food colouring (RED, YELLOW, BLUE)
Plastic Container with lid (we used preformed soda bottles)
Rain Saver Crystals (100g)
Spoons
1 Litre water jugs x3

Procedure:

Step 1
Fill each of the three jugs with water and add food colouring so you have one jug of each colour RED, YELLOW, BLUE. A good strong colour will give better results.

Step 2
Add 3 or 4 tea spoons of Rain Saver Crystal to each jug and stir. Let it stand until the crystals have soaked up all the water and food colouring.

Step 3
Start adding the mixture to the plastic container/ preform starting with RED, YELLOW, BLUE and then RED again. Make sure you have an even about of each layer. Make sure layers are packed tight and then close the lid. Extension: Experiment with different combinations and what the possible results will be.

Step 4
Observe your creations for the next 24/48 hours as the colours start to bleed and all the colours of the rainbow are formed. The end product should look like the example below.

RED, ORANGE, YELLOW, GREEN, BLUE, INDIGO, VIOLET

? Question ?

If I was to stir a rainbow in my mixing bowl it would turn WHITE.
If I was to mix all the primary colours together it would turn BROWN.

WHY ?

UPDATE: Create a T.V. Advertisement for a known product (optional)

Mr. Rees — Sat, 19 May 2012 00:05:41 +0000

In class this term we have been doing a lot of work with Persuasive Writing. For the holidays, if you want, I have a wonderful task for you to try that will help show your persuasive skills.

Create a 30 second advertisement for a known product. Make sure you think about the persuasive techniques you can use to help influence your target audience.

Bring your advert to school when we return from the holidays and I will organise time for them to be seen by the class. They will be uploaded to the class blog if you do not use names that identify you/friends/family during the advert or in the credits.

Names

If you would like your video displayed on this blog, make sure that you do not use names that identify you during the advert or in the credits.

Tips:

Put People in Your Commercial
People relate to other people. Putting people into your commercial can help draw your target audience in as opposed to a 30 second shot of a building’s interior, exterior and the parking area. Be careful about having people waving at the camera or standing there smiling. Have them doing something that relates to your product so your commercial doesn’t look like a photo that’s come to life.

Plan Out Your Video
It’s important not to cram a bunch of video scenes into the small amount of time you have for your commercial. Your video should tell the story about what you’re advertising even if a customer has their volume turned down. If you want to create a very simple advert with little or know editing then make sure it is only one scene.

Writing the Script
Make sure your commercial’s script times out to 30 seconds. Use short sentences that grab your potential customer’s attention. You’ve got a very limited time frame to capture your audience and you need to get your message across quickly. Don’t get wrapped up in long sentences. Keep them short and punchy. Your audio should also tell the customer what you’re advertising even if the customer is in another room and can’t see the TV when your commercial airs.

What causes a rainbow?

Mr. Rees — Tue, 15 May 2012 05:21:20 +0000

One of the most important experiments on light was made by Isaac Newton. He was the greatest of all English men of science. He discovered that sunshine (white light) is made up of many colours. Over 300 years ago, Sir Isaac Newton passed a beam of white light through a prism. A prism is a triangular piece of glass, which allows light to spread out into a band of six colors. These colors are red, orange, yellow, green, blue and violet. Newton then sent this light through a second prism where the light became white once again.

What did Sir Isaac Newton do?
He first took the white light apart and then he put it back together again.

The most common example of a spectrum is the rainbow created in nature. The rainbow is caused by sunshine (white light) shining on water droplets that are in the air just after a summer shower. Thousands of these water droplets break up the light, just like Sir Isaac Newton’s prism. Can you make a rainbow? Of course! Make your own rainbow by turning on the garden hose, which has a nozzle that will make a fine mist, or spray. Make sure the sunlight is coming over your shoulder. You have made a rainbow.

If light is white and all we see is light why do things appear different colours?
Objects absorb some of the colours in the white light and then reflects the rest. The colours that are reflected provide the colour of a specific object. Think about these three basic colours (Red, Blue, Green), if an object absorbs green but reflects blue and red then the object will be purple. The mix of blue and red light gives us purple.

Did you know?
The computer screen you are looking at now can only produce three colours – Red, Blue and Green. So how do we see white on the screen? It follows Newton’s experiments on light and puts the three colours all together to create white.

EXPERIMENT TO TRY

Colour Wheel

Print out this template (you may need a PDF reader like the one from Adobe).
Cut out the discs and then put a toothpick, or pencil, through the centre. You may need to fix the disc with a bit of sticky tape.
Spin the wheel and have a look at the colours that are created. Look at the outer ring of the first disc shown above and the colour should disappear.
Repeat with the other patterns and colours.

Note: You may need to stick the paper on to cardboard if your paper is too thin.

Bring your complete wheel to school and receive some Rees Dollars for your effort.

Fun Facts about Light

We do not know of anything in our universe that travels faster than light. The sunlight we see today left the sun 93 million miles away to reach us about 10 minutes later. Light from stars farther away may have taken billions of years to reach our eyes. How many times can light travel around the world while you are saying your name? ……………..more than four times.

Class Auction – ReesBank Rewards

Mr. Rees — Sun, 13 May 2012 22:25:37 +0000

On Friday we had a trial Auction to see how well it would work to help support the ReesBank reward system. Everyone really enjoyed the auction with many frantic hands being raised during the bidding process. Marica did a fantastic job as Auctioneer and Stella was an exceptional Auctioneer’s Assistant.

Unfortunately it was very time sapping and is unlikely to happen again during class time. If the auction was held at lunch or perhaps on the last day of term, time would not be such a big issue.

List of items sold:

126 – $36 – Fluoro Liquid Sharpener - Kai
108 – $100 – Fish Keeper Job – Nausheen and Marica
120 – $100 – Insect Keeper Job – Skye and Dorsa
113 – $55 – Naming New Fish – Luc
119 – $65 – Fluoro Liquid Sharpener – Corben
124 – $30 – Pen – Kiyoka
125 - $61 – Pen – Janani
126 – $40 – Ruler -Kai
101 – $41 – Fish Eraser – Jo
102 – $35 – 2x Pen – Arseny
101 – $40 – Glow Stick – Jo
116 – $85 – Glow Stick – Jose
117 – $215 – Mystery Envelope ($200) – Heba

As a class you have earned $3 091.00 in 3 weeks (an average of around $100 per student) and spent $903.00 at auction.

If we did hold the auction again, how do you think it could be improved?

Tongue Twisters – Alliteration

Mr. Rees — Mon, 07 May 2012 11:34:26 +0000

Alliteration is the repetition of the same consonant sound in the beginning of multiple words in a sentence. In Latin, alliteration means “putting words together”.

Several rules must apply before a phrase is considered to contain alliteration. In each word, the first sound or the first stressed syllable must be identical. The letters used in the word are not taken into consideration. Therefore, “city” and “care” in a phrase would not alliterate, but the words “city” and “safe” do.

Each word must also come right after the other, or with only a few words separating them. Some examples are “Sally saw seashells” and “good children get many grapes.” A minimum of two words must meet these requirements.

The function of alliteration in speech is to be both attention getting and memorable. Advertisers and politicians use alliteration frequently for catchphrases, slogans, and jingles.

Go to TONGUE TWISTERS FOR KIDS and try saying a few tongue twisters. Start saying them slow and then speed it up as you get better at it.

Task:

In the comments, write your own Alliteration tongue twister that includes Onomatopoeia (words that imitate an actual sound such as woof, meow, tweet, slither, hiss, sizzle or slurp).

Example: The snake slithered through the slimey sludge of the swamp.

The video below is of a girl speed reading ‘Fox in Sock’s by Dr Suess. Fox in Socks contains both Alliteration and Onomatopoeia.
