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 ?

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

1. Print out this template (you may need a PDF reader like the one from Adobe).
2. 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.
3. 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.
4. 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.

This term we have successfully used Monopoly for our table based rewards. Hundreds of Hotels and Houses have been collected by everyone. Congratulations! In Term 2, I would like to introduce a new system, REESBANK, the online virtual bank account for each of you.

How it works:

You will have a virtual bank account that you can deposit and withdraw virtual money from. When you are rewarded in class for completing work/ good behaviour/ etc, you will be given a REESBANK note with a $ value and a serial number.

At home you log into your virtual bank account and type in the serial number to deposit your reward money. This money will then start to collect interest, currently at 5% per month.

Special Offer

On the reverse side of the REESBANK note is a Special Offer (similar to loyalty cards) that requires you to earn five stamps that will then increase the value of your reward.

Bank Tellers

I need to employ Bank Tellers who will get paid to do some additional tasks. Checking deposits, transferring money, etc. Please leave a comment if you are interested.

What do we do with our savings? 

This is virtual money, we can’t spend it in the real world. We could just save it and the students with the highest amounts at the end of the term win a special reward. Or, we could spend it with things like buying fun time, renting a class squishie for a day, etc.

What are your ideas about what we can do with our savings?

We swear that we will take part in these Olympic Games in the true spirit of sportsmanship and that we will respect and abide by the rules which govern them for the glory of the sport and the honour of our country.

Let the games begin: Rice Bubble Hurdles, Rice Bubble Archery, Rice Bubble Tennis, Rice Bubble Shot put, Rice Bubble Rugby and Rice Bubble Passitball.

You are older now and your room is not as wonderful as it once was.  It is time to try convince your parents to let you re-design your room.

When you go to ask them they reply:

NO!

and give you the following objections:

1. It’s too expensive.
2. You never even clean your room; why re-design?
3. You already spend too much time there.  We only see you at meals as it is now.
4. or You never spend any time in your room; why should we bother?
5. Your brother (sister) is going to feel left out.  We can’t start redecorating everyone’s room.
6. Your taste in interior decoration is questionable.  We can’t paint ceilings and walls in school colours or indulge in other such fads.
7. I’ll end up doing all the work.  I don’t have the time or the energy.
8. It’ll cost too much.
9. I said “No!”

Task: Write a persuasion that will convince your parents to change their mind.

The audience for your persuasion are your parents - an audience opposed to what you have to say. You must use direct speech and powerful words, though respectful and appropriate, to convince them of your side of the issue. This is done by providing arguments against the 9 objections from your parents. You may find it difficult to convince them on all nine objections, just do your best (8 out of 9 objections could still convince your parents to say yes).

Title: I want to re-design my room

Position: (outlines the issue and your point of view)

Arguments: ….. because ……

Conclusion: (restating position and main arguements)

When you have finished create a plan of how your new room will look.

Power Words

Power words are words used to help make a statement stronger. Click below to see a few examples to do with selling.

Our class will base our picture on a traditional Dutch girl costume.

To help with the decoration we also need to make a few accessories. If you have time at home and a parent who can help, you can try and make the following. Leave a comment if you are going to have a go.

We need to make:

• One Dutch Hat (template)
• Six Yellow Tulips (template)
• One pair of Dutch Clogs (template – the 50% reduced size)

Have you ever said something to someone and they misunderstood the meaning of what you said? When you think back over what you said, you wonder how they managed to misunderstand you.

Many times, it is not what was said, but how it was said that causes these reactions. Voice inflection can mean so much more than the actual words that are spoken. Voice inflection means to change your voice. You can vary your voice by stressing a word or phrase, stretching a word or phrase, or pausing before a word or phrase.

I have written the sentence below seven times and have underlined a different word each time. Say each sentence out loud, putting emphasis on the underlined word.  Can you work out what the meaning of each sentence is?

I didn’t say George stole my red pen

I didn’t say George stole my red pen.

I didn’t say George stole my red pen.

I didn’t say George stole my red pen.

I didn’t say George stole my red pen.

I didn’t say George stole my red pen.

I didn’t say George stole my red pen.

I didn’t say George stole my red pen.
