Science Roadshow Sparks

Yesterday room 12 went to the science roadshow at Rotorua Intermediate. My favourite activity was the bed of nails, when I was lying on the bed of nails it felt like a massage on my back.  The reason the nails don’t dagger into your back is because there's so many nails that it can hold you body weight & not hurt, that’s why if you touch a nail it’s sharp.

The nails pricked my skin as I lay on the bed of nails.It burnt like fire on my back.Filled with nerves the first time I did it , as soon as I did it my nerves eased . But the question is how come you can do it and it does not hurt? Because on nail will but a bunch won’t it spreads your weight.

Slope Science

Today we were practising being scientists by using "The Scientific Method" to test the affect angle of a slope has on distance traveled. We worked in groups and everyone showed how awesome they were at participating and relating to others: great teamwork!


What is important about following the scientific method?

Why do scientists need to be able to work well in a team?

The Scienctific Method

This week we learned about THE SCIENTIFIC METHOD. It is how scientists solve problems and do their research. Mr Wood likes to eat apples but found that they go brown quickly when he sliced them. So we used THE SCIENTIFIC METHOD to try find a solution to the problem.

What other problems could would solve?

Making Animations

We have been learning how to make animations in Google Slides. An animation is when objects move around on the screen on their own. Any shape or text can be animated in Google Slides. We have been using our knowledge of how volcanoes erupt to create animated volcanoes. Look through our slideshow below to see some made by our class members. You must click on each slide to start the animation.

Coke Volcano

What we did: an experiment that room 12 did to see a similar reaction to a real volcano that is erupting and what it could be like.

Why we did it: to see a similar result of what a volcano would do if you were in one.

How to do the experiment: you need a 1.5 or 2 litre of coke and mint flavoured mentos. First make sure the coke bottle is secure. Then get the mentos ready so it falls into the bottle fast. When you're ready put the mentos in you will probably need 8 of the mentos out of the packet  Once you put the mentos in the bottle stand about 3 feet back.After a few seconds the coke volcano will erupt.

How it worked: when you put mentos in the coke it the makes the carbon dioxide rise

from the coke to make an explosion with a chemical reaction. The coke and gas in the bottle were like the magma in the magma chamber, and the neck of the bottle was like a volcano vent which is narrow. It exploded like a geyser.

How it was similar to a volcano: when you put mentos in the coke it's like the pressure from the volcano then the fizzy makes it erupt. The smaller the valve or vent, the bigger the explosion

We learnt what a volcano could look like when it erupts. The smaller the vent the bigger and higher the eruption.
