Slush Lab

By: Meg Daniel

Procedure

In all labs at the start put on goggles and at the end wash hands


AHS Snack

1) Collect the AHS Snack and a beaker

2) Take the AHS Snack and beaker back to the science lab

3) Pour the AHS Snack in to the beaker and find the volume of the snack, then record the mass

4) Weigh the AHS Snack and record the volume

5) Record other quantitative observation(s)

6) Record other qualitative observation(s)

Slush

1) grab a beaker and a pestle

2) go to the cooler with snow and scoop it up in the beaker to 140 mL use pestle to compress down

3)Record the volume

4)Weigh the Slush and record the weight

5) Record other quantitative observation(s)

6) Record other qualitative observation(s)

7) when finished cover with parafilm

8) Label beaker with group initials


Melted Slush

1) Grab beaker and remove parafilm

2) record the volume

3) weigh the slush and record

4) Record other quantitative observation(s)

5) Record other qualitative observation(s)

6) When finished cover up with the parafilm



Filtrate

1) Grab beaker and one empty beaker of 150 mL then remove parafilm

2) Grab filter paper and fold in to cone shape

3) put the cone shape filter over the empty beaker and start to pour the filtrate in

4) Wait for a little bit ( this step may take a while) When the filterate is almost done filtering try tilting the cone to have the filtrate flow faster

5) Weigh and record mass

6) Record volume

7) Record other observation(s)

8) Cover up the beaker with the filtrate in it and keep the dry solids together


Dissolved Solids

First boil down the liquid filtrate till you get the what is left

1) Grab the dissolved solids

2) Then plug in a microscope

3) Put the dissolved solids in to a glass container

4) put the glass container under the microscope

6) Record observations

6) Draw what is seen

Analysis

  • Pie Graph
The percentages are far greater in the beginning of the lab for the slush percentages than at the end




  • Bar Graph
The masses of the slush is far greater with the first test because it was more like snow than the next one because the "slush" melting so there will be less by the end of the lab



  • Line Graph
the distilled water reached the boiling point first because there is no salt in distilled water. Then the filtrate took longer beacuse of the salt in the water.

Physical Test Data Analysis

  • Conductivity

Distilled water it read zero so there was no conductivity in the distilled water in the Filtrate it read 63.113.

  • Acid / Base
for both the distilled water and the filtrate the litmus paper read neutral

The ph test the distilled water read a ph of 6 and the distilled water read a ph of 7


  • Density

24.6 filtrate

2.62 distled

Sources of Error

Sources of error for the slush to filtrate stages could be spilling the slush , the scale not being zeroed out even human error when taking the temperature there could have just been a air bubble in the thermometer. The hot plate once fully heated up the temperature could have faltered easily.

Conlcusion

look on the notes

Real Life Application

The process of filtration is the way of separating a liquid from a solid. The benefits is it can be easier to study solids and liquids separately. Some draw backs are it can take a long time to filtrate different solids from liquids. The first unique place is in hospitals for blood, in making tea, and in cars.
