Measuring spoon 

Milk 

pot or Container 

White vinegar 

paper towels

spoon

Mug

Food colouring,glitter, Cookie cutters 

Method:

1. Pour 1  cup of milk into a pot or microwaveable container  

2. Heat the milk in the microwave or the stove until it is steaming 

3. Add 4 teaspoons of white vinegar to a mug 

4. Add the hot milk to the mug with the vinegar 

5. scoop out the curds with a spoon and place them on a paper towel 

6. Fold the paper towel over the curds and press down to absorb excess liquid 

7. knead all the curds together into a ball of dough

8. You can colour your dough with food colouring 

9. You can add glitter to make
the dough sparkle 

10. You can use cookie cutters to shape your dough

11. Put all creations on a paper towel and let them dry overnight 

How did the consistency of the milk change during the plastic-making process?
it was normal milk until it curled.  

Fizzy frink and Mentos

 Aim: To see Which fizzy drink reacts the most Mentos lollies 

Hypothesis: I think that the coke is going to react the most with the Mentos. 

Equipment 

1. Mentos

2. Coke

3. Lemonade

4. Sparking Duet 

5. Ruler

6. Beaker 

Method 

1. Collected and set up the beaker 

2.  Got the 1st liquid and put 100 mls in the beaker.

3. Put the mentos into the liquid 

4. Measured the Height  of the fizz 

5. Repeat steps 1-4 with the second and third liquid

Photos: Two photos of my experiment.

Coke

Rainbow paper

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

Definition: chromatography is a method of separating out materials from mixture using liquid 

Materials:

1.  Boliing tube 

2. Pen 

3. Water

4. Filter paper

5. Scissors 

6.  Test tube stand 

7. Ruler 

8. Pencil 

Process

1. Cut up the filter paper into strips 

2.  Rule a like 1cm from the bottom of the paper strip 

3. Put 8ml of water into the bottom of the boiling tube 

4. Draw two coloured pen dots on the pencil line. 

5.  Drop the paper strip into the boiling tube and once it is touching the water at the bottom you can cress the top of the paper over. , 

6.  Watch, take 2 photos and observe the chromatography process on your paper

Skittles- Science

 Chromatography is a technique for the separation of a mixture by passing it int he solution or suspension through a medium in which the components move at different time 

Aim: To separate the colours from the skittles by using chromatography

Materials:

1. 6 Skittles 

2. Water 

3. Petri dish 

4. Beaker 

Progress: 

Step 1: Get your Equipment set up ready to pour 25 mLS of water into the perti dish with the skittles

Step 2. Place skittles into perti dish around edges 

Step 3. Pour 50mLS water gently into middle of the petri dish 

step 4. Watch as the water removes the dye from the skittles. See what colour reaches to middle fastest 

Step 5. Record your results  on table below 

Hands on fire :D

 Aim:

To Safely light my hands on fire. 

List and complete 4 ways of doing this safely

2. put some water into the tray

3. Squirt some detergent into water

4. Put on your Glasses

5. Tie up any long hair 

6. take off any jewellery 

7. Wet your hands wrist and arms 

8.Bubble the gas into the water

9. scoop the bubbles but not in water

Osmosis- Gummy Bears!

 Osmosis: The movement of solvent through that wall of a solid.

Aim: 

I want to find out what happens to Gummy Bears when we put them into different liquids

Prediction:

I think the Gummy Bears are going to shrink or grow in the liquids 

Method: 

Equipment 

- Three solutions- Water-Sugar- and salt

- Four Gummy Bears of the same colour 

- Two petri Dishes 

- Maker pen 

- Electronic Balance 

- Beaker 

Steps 

1. Get your Equipment 

2. Label Petri dishes with DRY, WATER, SALT WATER, SUGAR WATER 

3. Weight the Gummy Bears and record their weight on the petri Dish. 

4. Add 40mL of the solution into the petri dish. 

Findings:

Weight change 

Solvent	Dry	Wet
Water	2.35	4.50
Salt water	2.20	2.60
Sugar Water	2.22	3.29

FINDINGS:

The water that was included in the first gummy bear petri dish made the gummy bear change from a dry weight of (2.35)  to a wet Weight of (4.50) The difference between the two weights was the water in the water it absorbed more liquid  This means that the Gummy  bears absorbed this amount through the progress of osmosis. 

The salt water gummy bear petri dish had a change from a dry weight of 2.20  TO a wet weight of (2.60)  The difference in these weights are that the salt water grew more. 

The sugar water solution in the petri dish with the gummy bears made the gummy bear weigh 3.29 This means it absorbed 1.07 water in total 

The gummy bear that changed the most was the gummy bear in the normal  water. 

 

                                     Floods 

Last week there were floods around Christchurch and lots of other places I think that biggest flood was in Ashburton. It was really wet and cold for a couple days now it has been sunny.

Fact about the Flood in Ashburton 

Hundreds of north Canterbury residents have been evacuated from their homes - and further south, hundreds more Ashburton residents are on standby 

The entire Canterbury region is now under a state of emergency and around 75 schools and preschools are closed on Monday as residents prepare for more upheaval.

Ashburton mayor Neil Brown said some locals had already started to evacuate overnight as rising river levels continued.
