Two or more materials that retain (keep) their own properties.
What is a mixture?
100
Saltwater
Name one solution we experimented with in our lab?
100
Anything that you can change in an experiment that might affect the outcome.
What is a variable?
100
1. Take 50 ml of water and pour it into a bottle.
2. Take a funnel and pour 5 ml of a solute into the bottle.
3. Shake thoroughly
4. Check for saturation
5. Repeat
What process do you use to saturate a solution?
100
Two substances that mix completely and can no longer be seen as separate parts.
What is a solution?
200
Gravel and water
Diatomaceous earth and water
Name one mixture we experimented with in our experiments?
200
Yes
Are all solutions mixtures?
200
Release position
Angle
Length
Name one variable we measured in the swingers unit?
200
gram pieces
What is a more precise scientific material used to measure how how much solute it took to saturate a solution.
200
Solid that dissolves into the solvent (liquid).
A solute is...
300
Hands
Filter paper
Mesh Screen
How can you separate a mixture?
300
No, it is not see through.
Is milk considered a solution? Why or Whynot?
300
An experiment in which only ONE variable has changed, in order to tell whether it affected the outcome.
What is a controlled experiment?
300
Salt and Citric Acid
What two solutes did we use in our saturation labs?
300
Liquid that dissolves the solute (solid).
A solvent is...
400
Sizing of the filter paper and mesh screen.
Why couldn't all mixtures be separated by both mesh screens and filter paper.
400
Evaporation
What process can you use to separate a solution?
400
To ensure our answers/results are as accurate as possible.
What is the purpose of conducting multiple trials?
400
Solute has covered the bottom of the bottle and can no longer dissolve into the solvent.
What does saturation look like in a bottle?
400
When a solvent (liquid) has dissolved as much material as it can.
A saturated solution is...
500
No
Are all mixtures also solutions?
500
Crystals
After a saltwater solution was evaporated, what was left behind?
500
The greater the capacity, the more passengers the boat can hold.
What conclusion did you make from the lifeboats experiments?
500
Citric Acid
Which solute from our labs was more soluble?
500
The maximum amount of a solute that can dissolve in a solvent is called the _________________.
