Distallation - Chemicals & chaos

                                                               Distillation

Recap:  Last lesson we learnt that the process of evaporation is when a liquid turns into a gas. So we can separate a solution, by evaporating away the solvent to learnt a solute (solid). 

But what if we want to collect gas?? When we trap the gas and turn it back into a liquid this is called condensation.

What is it?

• Evaporation: heating a liquid, turns to a gas
• Condensation: cooling down a gas, turn into a liquid.

Experiment:                                  Separating a mixture using distillation

Aim: To separate a solute from a solvent in a solution using distillation.

Equipment: 

• A solution of saltwater
• Conical flask
• Heatproof mat
• A delivery tube and bung
• Bunsen burner
• Tripod
• Gauze mat 
• Retort stand
• Boss head and clamp
• Boiling tube

Method:

1. Set up the equipment as shown in the diagram
2. Add approximately 50 ml of saltwater to your conical flask
3. Light your bunsen burner. Open the air hole and gently push the bunsen burner under the tripod
4. Heat the solution until most of the solvent has been evaporated. Turn off your bunsen burner.

Hypothesis: When the coke is heated the sugar will solidify and stay in the flask and the liquid will be evaporated and travel all the way to the test tube and cool.

Observations: As soon as we put the Bunsen burner on the coke was already boiling, when the coke started to evaporate it was transferred through the bung and into the tube where it cools and turns into clear brown liquid.

Conclusion: Coke Zero has had less dissolved substances, when normal coke had more dissolved solids which was sugar.

Well being - Wananga

 In the last 2 weeks we have looked at Resilience - Emotional Awareness (understanding emotions) and impulses, I have come to realise that my emotions actually have effect on people around me.

Being able to control my emotions in different situations avoids:

- Breaking relationships with others

-  Mental breakdowns

- Healthy social well being

- Anger issues

- Conflict

Knowing how to react and respond in situations rather than acting on impulses means that not getting myself in trouble by making or doing something wrong. The effect that things have on my Social well being (Taha Whanau) when your being kind to someone your relationship becomes healthier but when your being unkind and rude to someone your relationship becomes unhealthy and is toxic.

30 sec film - Inside and out

1. What was the film about? 2 people playing a volleyball game but something goes terribly wrong

2. Something I enjoyed while making my film? All the laughs and us having fun with the video

3. Something I learned while making my film? That you shouldn't work with friends or people you can't focus with other wise you won't get work finish

4. Some film techniques I included were:

• Low angle
• High angle
• Eye level
• Birds eye view
• Long shot (wide)
• Close up

5. Something I found challenging was:

• Getting angles
• Making sure we got all the scenes

6. What I would do differently next time? 

- Go in a group with people who I work well with

- Have more ideas for angle shots

Challenge chart - Inside and out

This week for film studies we had to make a presentation for a challenge chart about 2 characters in the movie, we had to put the challenges they faced, how they reacted and what showed us about that characters. The 2 characters I chose was Coraline the main character of the movie and the other mother. The reason I chose these two characters was that they were showed more in the movie and we could see who they actually are. 

What am I learning?

Understanding how characters are developed in a film.

How does this work show my learning?

I created the show I can understand how the characters developed in a film.

What am I wondering as a result of this learning?

Is there other ways to show this working.

Tāne Māhuta

Today for Tāne Māhuta we had an idea that we should use the plums form the orchid and use them to make jam and maybe sauce so we can sell them. The reason why we're making jam for money is so we can buy fruit and vege seeds, tools and other stuff to make the school garden clean and beautiful. First we picked the plums, picked up some rubbish and then grab all the bark and dirt and move them to the compost area. So now here is the photos from last week and the ones from today.
