Osmosis/Egg Lab
By: Nicole Dressen
Problem to Solve: How the potentiometer of an orb changes in different substances.
Information Collected: A. Hypotonic: a substance with lower constriction when compared to an another(prenominal) substance.
B. Isotonic: when the stringency of two substances is the same.
C. Hypertonic: a substance with more concentration when compared to another substance.
Hypothesis: I think the mass of the fruitcake that is in the water will stay the same besides the mass of the testis that is in the sugar will growing mass.
Variables: The manipulated variables are the water and the sugar and the responding variable is the mass of the formal.
Directions: 1. pick up two globes in vinegar for one day. 2. convey two 200ml beakers and fill one with 150ml of water and the other with 150ml of corn whiskey syrup. 3. Measure the battalion of the eggs and understand. 4. Put one egg in the beaker of water and the other in the beaker of syrup. 5. Take both eggs out after 15 minutes and record each of their masses. 6. Repeat step 5 four times.
data/Observations:
?
Conclusion: Recall: We did a lab to learn round how the mass of an egg changes when it is set in different substances.
exempt: We recorded the masses of two eggs every 15 minutes. One was put in water man the other was put in corn syrup.
Results: The mass of the egg that was put in water increased while the mass of the egg that was put in corn syrup decreased.
Uncertainties: The eggs did not have the same mass to start out with and the collection plate could have been off.
New: I learned that the mass of an egg can change when put in different substances.
coterminous: Put more objects in different substances to see if their masses change.
Questions: 1. Substances move in and out of the cell membrane ever-changing the concentration levels in order to keep the cell balanced.
2. The mass of the egg in the corn syrup decreased while the mass of the egg in water increased.
3. Before we did anything to the egg, it was isosmotic because the cells...If you want to get a full essay, order it on our website: Orderessay
