What are the names of these 3 pieces of equipment that we used for our experiment?
marble / marbles
cylinder / cylinders
stopwatch / stopwatches
100
What liquid did Azad drop the marble into to test first in HG 32? Hint: it has sugar, salt and carbon dioxide.
cola
100
What state of matter is most of the Earth in?
a solid state of matter
200
Describe the atoms in a liquid.
less fixed than a solid, but less free than a gas
200
What is the name of water when it becomes solid?
ice
200
How do the atoms in a gas move?
freely and in different directions
200
Sami and Mesra tested the viscosities of two liquids in HG 29. What are they? 
shampoo and dishwashing liquid (soap)
200
What did Sora and Elnaz pour into the measuring cylinder?
Oil
200
What state of matter is Earth's inner core?
Solid
300
What makes an egg a viscous liquid (لزجة وسميكة)?
It has fat and protein.
300
What are the 3 properties of a solid?
- has a definite shape
- has a definite volume
- has a definite mass
300
If you mix C and and O2 and add heat, what gas to you get?
CO2 - carbon dioxide
300
Before we tested the liquids, we talked about aim and p..... In this picture, Ali p....... an egg's viscosity would be high. What is this word and its meaning?
prediction / predict
300
Who are the "maths guys" in HGs 36 and 32. They wrote the times (and calculated averages) on the whiteboard.
Zhekai = HG 36
Abed = HG 32
300
What state of matter is Earth's outer core?
Earth's outer core is liquid.
400
How does a liquid and its atoms behave in a container?
They take the shape of the container because they have volume. They can move around and slide past each other. The atoms of some liquids can mix together and become solutions.
400
When will a liquid become a solid?
When the temperature decreases to zero degrees.
400
What are 2 properities of a gas are NOT definite?
400
The viscosity test results were different in HGs 32/29 and HGs 36/28. What were the most viscous liquids?
HG 36/28 = golden syrup
HG 29/32 = shampoo
400
What was Mathias and Dima's jobs and what did they use to do this?
time keeping with the stopwatch
400
Plasma is ionized gas that is not common on earth. What are 3 natural examples of plasma can we see in the sky?
stars, the sun, lightning
500
Many people want solid, strong muscles. But most of the muscle is liquid! What % of your muscle is liquid? And which liquid is it?
75% water
500
How is it possible for a non-Newtonian fluid to behave like a solid?
A non-Newtonian fluid can behave like a solid when pressure/force is applied. This is because the atoms are pushed together and become fixed.
500
Explain how water becomes gaseous?
Water becomes a gas (water vapor or steam) through vaporization. It can happen with evaporation and boiling. The water molecules get more kinetic energy stop forces holding them together, so their state changes to a liquid they can go into the air as a gas.
500
What is the scientific defininition of viscocity? You need to use 3 special scientifc words.
Viscocity is the measurement of a liquid's resistence to flow. 
500
Who was the first student to drop the marble into water to test its viscosity?
Ahmed from HG 36
500
What state of matter is not found naturally on Earth?
BECs - Bose–Einstein Condensates
