2 solids that we used in our investigation
What are: paperclips sand and gravel beads
100
This happened when we mixed the sand and water
What is then sand sinks to the bottom
100
the two materials we used in our reactions investigations
What is baking soda and vinegar
100
centimeters in a meter
What is 100
100
We weight the mass of items using these
What are gram pieces
200
We used this to separate the paper clips
What is a magnet
200
This happens when you mix chalk and water
What is the mixture becomes cloudy and after a while the chalk settles to the bottom
200
the kind of reaction that took place when we mixed them
What is chemical reaction
200
decimeters in a centimeter
What is 10
200
We use this to find the mass of items
What is a balance scale
300
We used this to separate the beads
What is water
300
This happens when you mix salt and water-what is another word for disappear
What is the salt disolves and the mixture looks like water again
300
Observations you made after mixing them together
What is it bubbled and fizzed
300
centimeters in a meter
What is 100
300
when gas particles form a liquid
What is condensation
400
We used this to separate the paper clips
What is a screen
400
The mixture of salt and water form this
What is a solution
400
Which had more mass-the mixture of when you weighted them separately? Why?
What is mixture-because the gas escaped into the air so it weighed less after we mixed them
400
millimeters in a meter
What is 1000
400
When water changes from liquid to water vapor
What is evaporation
500
The reason why the screen helped to separate the gravel and the sand
What is the property of size-the sand went right through the holes because it was smaller than the gravel. The gravel stayed at the top
500
the scientific word for clear
What is transparent
500
the gas that formed when we mixed them together
What is Carbon Dioxide
500
meters in a kilometer
What is 1000
500
Another word for rain
What is precipitation
