8. Make sure you opoen the bottle in the kitchen sink as it might overflow. Open the cap bit by bit  allow the air to escape.

1. What is fermentation? The chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the giving off of heat.

2. What effect does sugar have on yeast? Too little sugar in dough can slow down yeast activity: Yeast is a lot like us – it loves to eat sugar. Yeast needs sugar to produce

Tasting

 Kia ora, Today we are tasting food in science class.

Aim: To Taste food  that are Sweet, Salty, Sour  or Bitter.

Method:

1. Get safety glasses and make a blindfold

2. Set up your chart and make sure that the person you are working with knows where to record your responses.

Blind taste testing result

Sample number	Sweet, sour, bitter, salty.	I think it is…….
Sample A	Sweet	sugar
Sample B	Salty	salt
Sample C	Salty	Salty something
Sample D	sour	Citric acid
Sample E	bitter	onions
Sample F	bitter	potato
Sample G	sweet	apple
Sample H	sour	lollies
Sample I	sweet	lollies

Science again.

Kia ora, Today we are learning about the safety of using a Bunsen Burner.

Method:

1. Get some safety glasses.

2. Get a Bunsen Burner.

3.  Place it on the heat mat.

4. Connect the hose to the gas tap and turn it to a orange flame while the hole is closed.

5. Setup the Tripod and and gauze mat with a  

Equipment needed:

1. Bunsen Burner.

2. Tripod.

3.  Gauze mat.

4. Heat mat.

5. Safety glasses

Flames:

1.  The hottest part of the flame is the inner flame.

2. The order of lighting a Bunsen Burner is the light of the match, Then Turn on the tap.

Information:

1. Broken glass will be put in a special glass bin.

2.  You can stop all glass taps by pressing the emergency stop button or tuning them off by hand.

3. the fire extinguisher is placed next to the door that leads outside or next to the whiteboard.

4. You should wear safety glasses when you are using fire.

Chilli tasting

 Chilli Tasting Experiment.

Kia ora, Today in science we are going to be tasting chilli's.

Aim: To see which is the best way to cool down the hot chillie taste in your mouth when eating chilli.

Hypothesis: I think that by using milk I will be able to remove the hot chilli taste from my mouth.

Equipment:

1. Milk.

2.  Water.

3. Coca cola.

4. Tasting cup.

5. Chilli.

Method:

1. You will work in groups of three or four for this experiment. Each person in the group will use one of the drinks with the chilli. You will then swap results in your group so that everyone has the same results.

2. Each member of the group needs to have their own tasting cup. This will be used for putting the different in as we cool off the chilli in our mouths.

3.  Place a piece of chilli in your mouth.

4. You will drink the liquid that you have in your cup.  As you do this you will complete a results chart.

You will be recording the following using Yes or No

1. The effectiveness of the liquid immediately.

2. The effectiveness of the liquid after 3 minutes.

Chilli Tasting Results

Record : Yes or No

	Immediately	After 3 minutes
Milk	NO	YES
Water	YES	YES
Coca Cola	YES	YES

Summary and Results:

The milk did not work immediately. After 3 minutes it had a small effect.

The coke had a small effect immediately. After 3 minutes coke had no effect.

The water had no effect immediately. After 3 minutes water did not stop the chilli taste.

Conclusion:

Milk could be a solution when eating spicy foods. Thats because milk helps your mouth handle Capsaicin, an oily chemical compound in chilli peppers. Capsaicin binds to a receptor in the tongue and creates a burning sensation. Casein protien found in milk can also bind to the capsaicin and wash it away.

Wonder blog.

 Kia ora, This week we have been learning about the movie, Wonder.

Here are my thoughts on the movie. Enjoy!

This week we watched a movie about Bullying and how it hurt a boy called Auggie.

He has a big sister called Via (Olivia).He was picked on because He was born with a

facial deformity, a combination of Treacher Collins syndrome and a hemifacial microsomia.

When he was wearing a mask on Halloween he heard his friend say

”I would kill myself if I looked like Auggie” “Since I was told to be his welcome buddy by

Mr Tushman he pretty much just follows me around” This made Auggie feel upset because

he had no other friends. Until Summer went over to him, Talked to him and then asked

him to be friends. Here’s a quote from Auggie: “I know I’m not an ordinary 10-year-old kid.

I mean sure, I do ordinary things. I eat ice cream. I ride my bike. I play ball. I have an Xbox.

Stuff like that makes me ordinary. I guess. I feel ordinary. Inside.

But I know ordinary kids don’t make other ordinary kids run away screaming in the

playgrounds. Here’s what I think: "The only reason I’m not ordinary is that no one else

sees  me that way.” The theme of the story is about. Bullying, Acceptance, Perception,

Friendship, Family, Courage, Kindness, Isolation and Diversity.

Hope you like my images too.

Bell week

Kia ora, This week we have a song by Six60  as the bell. I now have to find out things about the band and the song, I have researched some things about Six60 and here is my information.

Song name: That's all she wrote. 

Six60 formed in the year of 2008 in Dunedin with members being, Eli Paewai (drums) Chris Mac (bass) Ji Fraser (lead guitar) Marlon Gerbes (synths, samples) Matiu Walters (vocals, guitar). This song is a meaningful song about Matiu getting broken up with And him saying goodbye to his ex girlfriend. 

My opinion on having different school bells and different types of songs is that they are good song choices.

That's all she wrote

Gummy Bear Osmosis 2

 Kia ora, Today is another day of learning about Gummy Bear Osmosis this time we are going to be looking at how they have changed over the time period of a week, We are mostly looking at how much  water has been absorbed and what effect that had on the water and the gummy its self.

	Dry	Water	Salt water	Sugar water
Initial weight of Gummy Bear	5.81g	5.36g	5.73g	5.45g
Final weight of Gummy Bear	5.70g	6.52g	6.22g	6.05g
Weight difference	Lost 0.11g	Gain 1.16g	Gain 0.49g	Gain 0.60
Initial volume		40mL	40mL	40mL
Final volume		0mL	10mL	7mL
Volume difference		Lost 40mL	Lost 30mL	Lost 30mL

Discussion:

1. The normal water was transformed into the gummy bear the most.

2.The dry gummy bear lost 0.11 grams over a week.

3. The sugar water was diffused faster than the salt water.

Diffusion Meaning: Diffusion is the movement of a substance from an area of high concentration to an area of low concentration. Diffusion happens in liquids and gases because their particles move randomly from place to place. Diffusion is an important process for living things: it is how substances move in and out of cells.
