Toroa was lucky to have a special guest teacher, Mrs Okey, for our arts interchange on Monday. Because we will be using bubbles for our art, we are learning about the science of bubbles. Check out our learning below.
Explain Surface Tension
It's like when something's pulling it up, sideways, and down as well, so it can't move. - Bonnie
The bubbles are getting pulled together. - Ashley and Zara
The water molecules get pulled onto the rim of the coin, so the bubble forms over the coin without spilling over the edges. It depending how much water you added. - Brie C. and Olivia
Matter
Matter comes in three states: solid, liquid, and gas. - Inaki
Liquid and gas. - Anna
What causes a bubble to pop?
Lots of pressure. - Solomon
If it touches something dry, or if it touches a sharp object. - Brie C.
If you did it on the table and there were bumps and little bits of rock on the table, it would pop because they're sharp and dry. - Brie S.
When you or anything touches it that's dry, it causes it to pop because it's absorbing the moisture. If your finger was wet, it wouldn't pop the bubble. -Max He.
What is a bubble's layers made of?
Soap, water, soap, gas. - Zara
How are bubbles' colours formed?
Sometimes reflection, the angle of the light. - Max W.
It's like a crystal, when light hits it, it creates a rainbow. - Bella
It happens when light goes in on a diagonal. - Ashley
When the light enters in a straight line, it opens up into rainbow colours. - Brie C.
What is iridescence?
It's like rainbow colours, but they're all swirling. They're not like a bow, so you wouldn't call it rainbow. - Olivia
We had an iridescent piece of paper. When we held it up to the light, it changed colours depending on the angle. It was like a pāua shell. - Brie C.
It's metallic, shiny, and different colours. It's reflective. - Ashley
Wow! What fabulous answers! You guys were really listening hard.
ReplyDeleteJust a bit of clarification:
What causes a bubble to pop? Not a sharp object but a DRY and absorbent object. You can push a sharp wet object through a bubble. try cutting a bubble with a sharp wet knife!
How are colours formed? Refracted light (not reflected! that is when you look in a mirror) is when a light source enters a glass object on an ANGLE the light slows and bends (red bending the least, violet bending the most)
What is iridescence? It is several layers of light moving constantly therefore refracting light constantly. Bubbles have constantly moving liquid between layers 2 layers of soap.
You guys have nailed it! I can't wait to start drawing bubbles with you all next week. :) Rachael.
