My Story

For this activity we had to write about a school who never throws away it rubbish. I hope you enjoy it!

CFC's

This term we are looking at environmental science. For this activity we had to find out what CFC's are. Here is my slideshow.

Atmosphere

For this activity we had to make a diagram of the atmosphere.

My Pollution Survey

For this activity we had to survey 8 other, to find out what the know about pollution. Here are the results.

Arsonist

For this activity we had to find out what an arsonist is and the three elements that are needed to create fire. Here is my slideshow

Entomology

For this activity we had to find out what entomology was and how it solves crime. Here is my slide show.

Inks

For this activity we are separations inks, here is my slideshow.

My Board Game

For this activity we had to make a board game that involves Forensics, here is mine

Family of Fingerprints

For this activity we had to look at our fingerprints and compare them to our families. Here is a slide about the different types of finger prints.

Here is my fingerprints vs my families.

What Types of Finger Prints are There

For this activity we had to find out about the three different types of fingerprints. Here is my slide.

The Science Of The Art

Ideas

1. Clay mode of an eel
2. Custom of animals
3. Class movie
4. Dusk to Dawn of the creatures hunted down the last survivor is fire                                                - With fire staph, a person holds, on survivor that hides, in a dark room                                          -Has been ruining and ruining, for ever trying to escape' that has defeated some beast/creatures but has ran out of objects to use. That person could be domed that has hid at kyle park.                -has tripped over the rope barrier thingy in rolled down the hill.                                                                                                                                                                                                                  = Needed if made... Water balloons... Wooden sticks on fire, rope, makeup props, costume masks. fake blood etc

Plan

Aim:

I want to find out if you can colour flames.

Method:

1. Light candles and wait for the candles to melt
2. Pour in melted wax into the pot, add chemicals borax for green, and copper chloride for blue.
3. If you want add crayons.
4. Make sure everything is melted and mixed in.
5. Pour into the mold and gentle place in the candle wicks
6. Wait until it hardened and remove it from the mold.
7. Light and enjoy!

Equipment:

• Old candles
• Borax / Copper Chloride
• Candle Wick
• Candle Molds / Jars
• Green and Blue crayons
• A small pot
• Lighter

It hasn't worked new experiment

Here is a video we are looking at.

Method:

candle wax

cotton rope
lighter
alcohol
chemicals 

copper chloride
\

Doing

results
We tried adding crayons to melted candle wax to make coloured flame which did not work. Next we tried adding chemicals to melted wax but that still did not work.
We also tried putting string into a cemical liqued and lit it but that did not work ether.
We have now melted two old candles, crayons and a pinch of Copper Chloride. We added a cotten string as the candle wick. We used some ice-cream stick to hold it in place. They still have not changed colours.
Here is some photos of our homemade candles.

discussion
Flames change colour when chemical are added, or when it gets hotter that is why the crayons didn't change the colour of the flame. The chemicals  change colour because of the energy levels it creates.

evaluation
Even though our experiments did not work I have learnt a lot about fire and how it works.

Collecting Water

Planning

Aim:

I want to find out if you can remove salt from water.

Method:

1. Get a big bucket
2. Full it with water and then add some salt
3. Place a cup in the middle of the bucket, make sure that the cup rim is higher than the water level.
4. Cover the top of the bucket with glad rap, place a rock on the glad rap in the center of the bucket over the cup.
5. Put the bucket outside where it wont tip over and so the water can evaporate.
6. Look at it in the next morning there should be some water in the cup and salt on the bottom of the bucket.
7. There might still be some drops of water on the glad rap.

Equipment:

• Water
• Salt
• A Bucket
• Glad Rap
• A Stone
• A Cup

I think that doing this will remove at lest most of the salt from the water

Doing

Results:

The water in the beaker still tastes salty but not as bad as to originally water, over this week we made 40 ml. But we need 2 ls  to live on. Here a few photos of the experiments.

Water and cup/beaker in place

On windowsill everything in place

        

After one week

Discussion:

In the sun the water heated up and evaporated then condenses on the glad rap, and then the stone lets the water droplets slid into the cup. This experiment shows that you can remove clean water from salty water. This experiment is easy to put together but takes a very long time to work.

Evaluation:

On way to improve it to survive on is to have lots going at the same time, about 25 for one day for one person.

Hauora in Science

Planning

AIM: I want to find out how far I can sneeze.

Method:

1. Lay the paper out as far as you want on the ground, keep in mind it needs to be about 5 meters and strait.
2. Get a plastic cup and full it up with water.
3. Add 10 drips of food colouring to the water per 100 ml
4. Take a small sip of the mixture swish it around your mouth. Try and get 5 ml of the mixture.
5. Do not swallow!
6. Then time to sneeze. If you are unable to sneeze do a fake one.
7. Look ahead to try and make sure not to get it on your clothes.
8. If you get it on you try and wipe it off with a tissue
9. Measure where your germs have gone.

Equipment:

• Orange food colouring
• Water
• A big roll of butcher paper
• Tissues
• Cup
• Tape or heavy rocks

Doing

Me sneezing 
(When watching this video please mute it because of background noise)

Lorelei started and ended

Photo

Results

The farthest my sneeze went was 1.79 meters.
The others sneezed: 
1.13 meters
2.20 meters
2.60 meters
3.10 meters
0000
0000

Conclusion

I found out that spit can travel about three meters when you sneeze.

Discussion

Next I would like to find out, why do you have to close our eyes when you sneeze?

Explaining

Next time we will look after the food colouring and keep it away from others that are not in the group.

Why do we sneeze? We sneeze when a particle of dirt or something else  flies up your nose, then your next reaction is to get it out of your nose by your sneezing.

How To Be Safe in Science

Planing

Aim: I want to find out to be safe how to be safe in science

Equipment:

• Bucket
• Water
• Detergent
• Rubber Tube
• Safety glasses
• Gas tap
• Lighter

Method:

1.  Get a big bucket
2. Put a good squirt of detergent into the bucket
3. Full the bucket half way with cold water
4. If you have lose cloths take it off, pull your sleeves up and tie your hair up into a ponytail if you have long hair.
5. Connect a tube up to the gas tap, and put the other end into the water.
6. Turn on the gas and make some bubbles!
7. Put your safety goggles on!
8. Wet your hands and wrists up to your elbows
9. Get a scoop of bubbles.
10. Hold to bubbles away from your face.
11. Using a lighter, ignite the bottom of the bubbles
12. Slowly, open your hands!

Doing

Being set on fire was very scary the sudden heat burning your hands, the bright as the sun flames leaping up into the air, the terrifying black smoke lingering on the roof slowly disappears. Then as quickly as it starts if dies as you move your hands apart.

Explain

I wet my hands because fire and water do not mix so you do not burn. We roll up our sleeves to make sure not to burn our clothes. I was scared because of the adrenaline running though me as the fire started. Adrenaline is an old reaction it has been in us since we where in the stone age, the fight or fight of survival. Why don't fire burn in a circle? Fire burns upwards because the fire is made of gas and it is lighter than air and so the air pushes the fire upwards.
