Science - Chemicals

In Science this term 7/8Al and 7/8Wh are working together on home chemistry. I worked on this activities individually and made my table individually as well.  

Here's my table:

Name	Chemicals	Image	Solid,Liquid or Gas
Dishwashing Detergent	Sodium Chloride		Liquid
Lemon	Citric Acid		Liquid
Salt	Sodium Chloride		Solid
Vinegar	Sodium Lauroyl		Gas
Sugar	Carbohydrates		Solid
Air Freshener	Phthalates		Gas
Onion	Amino Acid		Gas
Lemonade	Carbon, Hydrogen and Oxygen		Liquid
Bleach	Sodium hypochlorite.		Gas
Baking Soda	Sodium bicarbonate		Solid

Here's another table on the chemicals.
This table is mixing two ingredient from the ten chemicals together and seeing what's the end product is.

Compounds	Method	Observation of reaction
Bleach Vinegar	Half cup of Bleach and half cup of Vinegar.	Makes a Toxic Chlorine gas that is poisonous.
Lemon Air Freshener	1 whole lemon cut in half with half cup of air freshener.	Makes a lemon scented air freshener.
Baking soda Dishing Washing detergent	1 tablespoon of baking soda with a half cup of dishing washing detergent	I can’t find a reaction to this experiment so here’s my hypothesis. I think that adding the 2 ingredients together, will make it bubble up and drool over the bottle.
Lemonade Salt	Half cup of lemonade and 1 teaspoon of salt	Makes the salt dissolve and the lemonade turns into some kind of extent. But there’s no chemical reaction to this experiment.
Sugar Onion	1 whole onion cut in half, trying to squeeze some juice out of both halves and 1 teaspoon of sugar.	I can’t find a reaction to this experiment so here’s my hypothesis. I think that nothing will happen doing this experiment.

Tāne Māhuta

I am part of the Tāne Māhuta group.

Our job is to make a difference in around the school so there's more native trees, plant and no sign of rubbish on the ground of Hornby High School. As a group we need to make our school clearer, healthier and improve on our school together.   

Today we walked around the school. Firstly we went to the school garden of where we can make changes to make it look healthier and clearer. Secondly we walked to the back field of where we can make changes to make it look less junkie and more clearer. The last place we went was the back area of the school of where we can make changes because building will be coming down later in the year or 2 

My favorite area at school is:
The part of the school beside Carmen Road. 

My best idea to improve our school is:
Planting more native tree that will attract the birds and make more shade over the school.

All of our scones were cooked for 10 minutes and 200 degrees Celsius but they didn't taste great. I liked this experiment but it was to do with food and baking.

Tāne Māhuta - Rubbish Day

Tāne Māhuta

Today 7/8Al, 7/8Mt, 7/8Wh, 7/8Ts had a day picking up rubbish around the school. So today was about making our school Hornby High clearer and healthier.

Where?

Today we went to 4 places around the school to pick up rubbish. First we went to the compost bin by the garden. Class 7/8Al, 7/8Mt cleared the rubbish away from the soil, weeds and broken tree. Secondly we went to the tennis courts near the compost bin by the garden. Class 7/8Wh, 7/8Ts cleared the rubbish from the bushes around the fencing. Thirdly all 4 classes went to the back field to clear the rubbish away. Fourthly all 4 classes went to the end part of school by Carmen Road.

What?

While picking up rubbish we found some weird items. Like: a phone, a $5 dollar note, some smokes, some alcohol bottles that had been smashed into parts and more. We also found: plastic bottles, chips packets and more.

Here's some photo as a group...

Start Picking Up Rubbish.

Even If You See Some That You Don't Drop.

Chromatography - Science

Aim: To separate colours by using the process of chromatography.

Definition: A technique for separating the different parts of a mixture / solid using liquid.

Rainbow paper

Materials:

1. Filter paper 

2. Container

3. Felts - {Black, Red and Green} 

4. Water 

5. Pencil

6. Ruler 

Process:

Step 1: With a ruler and pencil and at the bottom of the filter paper rule 1 cm, after that rule the top of the filter paper 2 cm. 

Step 2: With 3 colored felts {Black, Red & Green} Put a small circle on the pencil line using each color.

Step 3: At the 2 cm pencil line we folded it back.

Step 4: After that we hooked the bent part on the container, and left it there.

Step 5: The teacher came around and poured water into the container. 

Step 6: After the water went in. We had to wait and after a few seconds the colors started rises to the top of the filter paper.

Findings: Write about what happened. As you can see once the water went in the container, the 3 colors from the felt pens started rising to the top of the filter paper.

Reflection: What have I learnt from this experiment?  That water can make felt pens rise on filter paper.

Skittles

Materials;

1. Petrie dish  
2. 5 Skittles {Purple, Green, Red, Yellow and Orange}  
3. Water 

Process:

Step 1: As a group we went up to the teacher and got a petrie dish that had five different colored skittles {Purple, Green, Red, Yellow and Orange} in it.

Step 2: When we got the petrie dish with the 5 different colors, we set the skittles {Purple, Green, Red, Yellow and Orange} on the sides with the same lengths apart.

Step 3: The teacher came around and poured some water into the petrie dish.  

Step 4: After the water went in. We had the wait and after a few seconds the colored started evacuating.  

Step 5: When the progress finished, as a group we shared the skittles because we were allowed to eat them. 

Findings: Write about what happened. As you can see once the water went in the petire dish the 5 skittles started dissolving.  

Reflection: What have I learnt from this experiment?  That water can make skittles dissolve in color.

What did the colours do?  Once the skittle started dissolving, the water turned different colors. 

Did the colours mix together?  Yes the colors did mix's together.

Why or why not?  Only because when the skittles started dissolving the color started evacuating.

Dirty Water Experiment

Aim: To make a filtration plant using household materials.

Water Filtration Plant

Today 7/8Al and 7/8Wh had science, we did an experiment called dirty water. We worked in groups to do this experiment, in my group I had Addyson and Hope. This experiment actually made me learn something about the water in New Zealand. I learnt that it takes hours or days to make our water drinkable, so be thankful.  

What is filtration?

Filtration is separating solids from liquids by adding a medium through which only the liquid can pass. 

Examples are: 

1. Kidney 
2. Swimming pool
3. A water jug
4. Coffee plunger

Materials

1. Bottle
2. Filter paper
3. Sand 
4. Pebbles/Stones 
5. Dirty water
6. Scissors 

Process

STEP 1

As a group we cut the bottle in half and timed the tops so they weren't sharp. 

STEP 2

As a group we put the top half of the bottle upside down in the bottom half of the bottle.

STEP 3

As a group we folded the filter paper in quarters and it was shaped like a cone. After folding the filter paper we added sand and patted it down like solid. After you do that pour pebbles/stones on top of the sand.   

STEP 4

As a group we added 2 cups of dirty water.  

STEP 5

As a group after adding the dirty water. We watched the water pour through the different ingredient in the funnel. 

Why it didn't go good?    - Conclusion

For this experiment the water was a meant to drip through but our poured, then slowly poured and then dripped fast.

 

Stop Motion - Art

Two weeks ago 7/8Al and 7/8Wh are working together in art this term. For art we are using stop motion which for us is making a 20 second long film to present in week 9 at the end of term. We are either using plaster clay, lego or drawing on a whiteboard. We chose to use plaster clay. In my group is Myself, Latisha and Maddison. 

Characters we are using form a Roald Dahl Book: x2 Witches and a Potion Maker. 

What is your end outside?

For me and my group to complete a 20 second film by week 9. Also to have our storyboard and script finished before starting to film. 

What have you done so far to get there?

Completed our storyboard and half way thought finishing the script. Also sorted out the characters, costumes and props.

What do you still need to do?

Complete the script. Make the setting and characters. 

Brief outline of your story?

x2 Witches walk into the Position Maker shop. The Position Maker gives us poisonous position without us knowing. The next day we turn evil then we die. After us dying the Position Maker jumps all over us.
