Brine Shrimp Write Up
Materials
Ocean,Himalayan and Table Salt 15g each
900 ml of Bottled Water
3g of Brine Shrimp Eggs
3 Bottles (Identical)
Brine Shrimp Background
Live in salt lakes mostly
They can survive in water ranging from 3% to 33% salinity
temperature of the water also varies greatly from around 6 to 37 deg C
optimal temperature at about 25 deg C
obtain food by filtering small particles
grow to about 15 mm
Swims upside down
Optimal Salinity 3-5% salinity
Lab Background
Set-Up 1:!:
Table Salt
Bottled Water
Set-Up 2:!:
Himalayan Salt
Bottled Water
Set-Up 3:!:
Control Set-up
Ocean Salt
(Instant Ocean)
Bottled Water
IV:!:
Type of Salt in Solution
DV:!:
Amount of Hatched Eggs
How Long The Shrimp Live
Constants:!:
Amount of water
Amount of salt
Amount of eggs
Identical Bottles
Same water
Set-up Procedures
2)Put 15g of Instant Ocean salt in one
3)Put 15g of himalayan salt in another one
1) Fill three bottles with 285ml of bottled water
4)Put 15g of table salt in the third one
5)place all of the bottles in the same lighting
Leave the caps off
Procedure for Data Gathering
1) take a 2ml sample from the bottles
2)Put that sample into a petri dish
3) Count how many shrimp are in the sample
4) Multiply that number by 150
5) The result is the approximate number of brine shrimp in the bottle
6) Repeat 3 times to get an average
This Should be repeated for each bottle
Data
Ocean Salt
Day 1) 0
Day 2) 0
Table Salt
Day 1) 0
Day 2) 2400
Himalayan Salt
Day 1) 0
Day 2) 150
Conclusions
Table salt was better than Ocean salt which is an odd result
Answer to Q:
Table Salt hatched the greatest number of shrimp
but in the past ocean salt has hatched the most
this could be an anomaly
Experimental Q: Do different salt affect the ability to hatch of a shrimp?
