Make a paper clip float

Does a paper clip float or not?.

The things you will need is:

clean dry paper clips
tissue paper
a bowl of water ( We used beakers )
pencil with eraser

What we need to do is:

 Fill the bowl with water to try to make the paper clip float

Tear a piece of tissue paper about half the size of a dollar bill

Gently drop the tissue flat onto the surface of the water

Gently place a dry paper clip flat onto the tissue (try not to touch the water or the tissue)

Use the eraser at the end of the pencil to carefully poke the tissue (not the paper clip) until the tissue sinks. The tissue will sink and leave the paper clip floating!

It works with a little something scientist call Surface tension. Surface tension basically means there is a sort of skin on the surface of the water. Where the water molecules hold tight together. If the conditions are tight then it will be strong enough to hold the paper clip. The paper clip is not actually floating by it self it is being held up by the surface tension. Many insects such as water strider use this skin to walk across streams. 

I think mine will float because it seems easy enough when I saw my classes paper clips float.

Here are some photos of how it went.

With the tissue

Sunken

My experiment was unsuccessful. 

I saw every ones else paper clip and it was floating so I thought mine was going to float.

Did you try to make a paper clip float?, you should.

Blobs in a bottle

Today in science Addyson, Anneleise and I made Lava Lamps. 

It was really fun making this lava lamp and it worked pretty well.

Our ingredients are 3/4 cup of water, Vegetable oil, Quick Eze tablets and food coloring.

Our lava Lamp didn't work as well as we thought it would be it was still a success. 

The Oil is lighter than the water so when we put food coloring in it goes straight to the water and colors it. the quick eze desolves and makes bubbles which creates the lava affect.

Our Hui

Hey guys/girls,
Today I'm going to tell you about 7Als learning Hui. For people who don't know what Hui means it means assembly. Okay anyways for our Hui I was the M.C basically the host. My heart was pounding with nervousness and I was also the narrator for "Chicken little" readers theatre. There were some technical difficulty's with the sound but we managed to get through it.

My sister came to watch me and it was embarrassing because she was filming me. I did mess up a few times because I was so nervous but It was fine. :D

The performers in my class were Levi, Callum, Tyler, Skyler, Rieya, Matua, Blake, Keghan, Megan, Axle, Tehya and me.

Here is a photo about the house posters

And sugar experiment.

I hope you liked my blog post.

I post again soon BYE.

Coke and Mentos

We can do better: We need to try several experiements to see which one works best

Equipment:

Ruler

Beaker

Thermometer

Coke Mentos

Measuring flask

Method:

Stage 1: ( All groups)

1. Add 150ml of coke to a measuring flask
2. Place the flask in the sink.
3. Drop in 1 mentos a watch the effect.

Group 1  ( Levi)

Test 1

1. Heat up 50ml in a beaker of coke ( Using a thermometer heat it to 75 degrees)
2. Place the beaker ion the sink and add a mentos.

Test 2

1. Add 50 ml of cold diet coke to a beaker
2. Add 5 mentos.
3. Record the hieght it reachs

Group 2  ( Tehya)

Test 1

1. Heat up 50ml in a beaker of coke ( Using a thermometer heat it to 45 degrees)
2. Place the beaker ion the sink and add a mentos.

Test 2

1. Add 50 ml of cold diet coke to a beaker
2. Add 5 mentos.
3. Record the hieght it reach

Group 3  (Lars)

Test 1

3. Record the height it reach

Group 4  (Jaz)

2. Place the beaker ion the sink and add a mentos.

Test 2

1. Add 50 ml of cold diet coke to a beaker

3. Record the height it reach

Findings:

Add your measurements to the table

Liquid	Height
Coke
Crushed mentos
Coke zero	Nothing
75 Degrees
45 Degrees
30 Degrees
15 Degrees

More investigations:

1. Does it work better with hot Coke( group 1) , warm Coke ( group 2 ) or cold Coke?( group 3)
