Science ~ Week 3

DTE

For the past few weeks we have been making games revolving around community issues of choice, Callum (Callum's Blog) and I made a game together because i didn't have a Chromebook for some time as i am writing this i now do. We made a game were you had to vs the pests in an arena and the pest were trying to take over New Zealand and we had to get rid of them there were diffrent doors to unlock with hidden and not so hidden keys, there is also spots that you can get into called Secret Areas. I helped callum on his computer do some coding, traps, ideas for battles, boss battle glitch fixing (bug repair) and backdrop ideas. here are some pictures of the character and game.

The game isn't finished yet but we tried really hard to get it done.

Reflection:

What i found hardest was to stay on task and keep on track.
I could change that by keeping more control of myself and working well with the people around me.

Science - Chromatography

Chromatography is a laboratory technique for the separation of a mixture. The mixture is dissolved in a fluid called the mobile phase, which carries it through a structure holding another material called the stationary phase. The various constituents of the mixture travel at different speeds, causing them to separate.

P.E Week 1

Today we learnt about Multi-Sports and how to trap a ball in football it was not that fun for me because i knew how to trap and I don't like multi-sports. Basically multi-sports is a mix off sports and there's 2 teams. The teams must be divided fairly and they go to opposite sides of a gym the teacher calls out a sport and a number. The number means number of people on each side to go and play the sport given they play then the next number of people repeat and so on and obviously we learnt how to trap a ball. :)

Crazy Crystals

To learn about a saturated solution and how to make crystals

Borax Crystals

Materials

1 Pipe Cleaner x3

2 Spoon

3 Water (Preferably warm) (Half Cup)

4 Borax (8 tablespoons)

5 Cup 

Process

Step 1: Add 1/4 Of A Cup Of Borax Into A Cup

Step 2: Add Water In To The 3/4 Mark

Step 3: Mix Until The Borax Has Dissolved 

Step 4: Make The Pipe Cleaners Into A Star

Step 5: Clip The Pipe Cleaners On To The Side Of The Cup

Step 6: Leave For 2 Days

Sugar Crystals

Materials

1) Sugar

2) Pipe Cleaner

3) Cup

4) Water (Half Cup)

5) Peg

6) Spoon

Process

Step 1: Add 1/4 Of A Cup Of Sugar Into A Cup

Step 2: Add Water In To The 3/4 Mark

Step 3: Mix Until The Sugar Has Dissolved 

Step 4: This Time Use One Pipe Cleaner

Step 5: Clip The Pipe Cleaner On To The Side Of The Cup

Step 6: Leave For 2 Days

Salt Crystals

Materials

1)Salt

2)Pipe Cleaaner

3)Peg

4)Cup

5)Water (Half Cup)

6) Spoon

Process

Step 1: Add 1/4 Of A Cup Of Salt Into A Cup

Step 2: Add Water In To The 3/4 Mark

Step 3: Mix Until The Salt Has Dissolved 

Step 4:Use One Pipe Cleaner

Step 5: Clip The Pipe Cleaner On To The Side Of The Cup

Step 6: Leave For 2 Days

Findings

Describe your crystals in the table below.

Crystal Type	Shape (Describe the shape)	Size (of individual crystals)	Hardness (Crumbly to Rock Hard)
Borax	Cubical		Hard
Sugar	Cubical		Crumbly
Salt	Cubical		Medium

What crystals worked out best and why?

The saturated sugar mixture has worked out poorly, there was not any trace of crystallization in the cup or around the pipe cleaner that we've used. The most probable reason that we can think of why it hasn't worked is that our mixture has not been saturated enough. We concluded that because our mixture was still very much liquid and not almost as thick as syrup.

However, the salt and borax mixture worked out like magic. They were the best results that we've had in this experiment. Though there were more crystals in the borax mixture; the container in which we had the salt mixture had more crystals in and around the inside of it. it was quite thin but at the least, it was very much visible when looked upon closely.

The experiment was a success except for the sugar mixture that we did, which we figured was not as saturated as the salt and borax mixture.
