exploding coke

aim: to see if  coke explodes when as mentos lolly b is dropped into it using different temperatures and different kinds of coke.

Hypotosus:

The coke will explode and it will go over 10 cm.

Equipment:

Ruler

Beaker

Thermometer

Coke Mentos

Measuring flask

Method:

Task 1:

1. 
   

Task 2:

1. heat up 150ml in a beaker of coke(using a thermometer to heat it to 15 degrees).
2. place the beaker in the sink and add mentos.

Findings:

6 Mentos lollies were dropped into a bottle of coke. the height of the fountain of coke was measured in centimetres.

A Mentos was crushed and dropped into the coke. This showed no result.

Liquid	Height
Coke	48c m
Crushed Mentos	No result
Coke Zero	44 cm
heated to 15 degrees	nothing but a few bubbles

this was the result of the heated experiment

The Scientific Method

Aim: to compare the boiling point of tap water and salt water

Hypothesis: I think salt water will be higher because the salt might give ti a boost

Equipment:
150 mls of tap water
2 teaspoons of salt
2 beakers with water
Bunsen burner
Bunsen burner tripod
heat resistant mat
gauze mat
thermometer

Method:

1. collect equipment
2. attach bunsen burner to a gas tap
3. fill two beakers with water
4. add salt to one beaker and mix
5. place the beaker with tap water on the tripod
6. place bunsen burner on the heat mat under neath
7. light the bunsen burner and adjust the flame to blue
8. as it heats up place the thermometer in the beaker of water until it is boiling
9. record results on blog
10. repeat the process with salt water

findings:

Tap water: The tap water boiled at 100 degrees.

Salt water: The salt water boiled at 99 degrees.
So the tap water boiled higher.

Orana wildlife park

On Monday the 7th of August the year 7's and 8's went to Orana Wildlife Park. At Orana there were lots of animals including rhinos, zebras, lions, tigers, Tasmanian devils and geckos. We were mostly looking at endangered animals and talking about what made them endangered. We used H.I.P.P.O which stands for Habitat loss, Introductions, Population growth, Pollution and Overexploitation. It was a lot of fun, there were sooo many things to look at. We started of by eating morning tea then we went down to see the cheaters. After the cheaters we saw the

Equipment:

Water

Soap (detergent)

Lighter

Safety glasses

Lab coat

Method:

1. Be safe.
2. Wet your hands wrists and forearms.
3. Grab a scoop of bubbles.
4. Hold the bubbles up in front of your face as far away from you as you can.

It was really scary.
This is what you do.
