| Eggs represent cells | Data Analysis | Implications |
|---|---|---|
|
The egg "skin" represents the cell membrane
Which cell organelle does the egg "skin" represent?
|
An external environment of pure water made the egg get bigger
Which liquid(s) caused the egg to swell or become heavier?
|
Breaking the egg, not wiping off the egg before weighing it, weighing the egg with the liquid
What are some errors that people could have made in this lab?
|
|
The egg white represents the cytoplasm (liquid inside the cell)
Which cell organelle does the egg white represent?
|
An external environment of corn syrup made the egg become smaller
Which liquid(s) caused the egg to shrink or become lighter?
|
The egg in corn syrup represents Josh because he drank sugary drinks, not pure water, and then got dehydrated
Which egg represents Josh?
|
|
Yes, water can pass through the egg "skin" or membrane
Can water go through the egg "skin?"
|
When an egg is placed in pure water, the water molecules move through the membrane into the egg
When an egg is placed in water, which direction do the water molecules move?
|
Temperature of liquid, amount of liquid, eggs had both been soaked in vinegar, amount of time that we let them sit in the new environment
In this lab, what factors were the same between your two egg setups?
|
|
Corn syrup is a mixture of sugar and water
Which answer choice describes corn syrup?
a) water mixed with salt b) water mixed with sugar c) water mixed with protein d) water, only |
When an egg is placed in corn syrup, the water molecules move through the membrane out of the egg
When an egg is placed in corn syrup, which direction do the water molecules move?
|
So you know that the differences in mass are caused by the external environment, not temperature or any other factor
Why is it important to keep everything the same except the liquid that you put the egg in?
