Egg Lab Post!

     Intruduction/Procedures: In class we have been talking about Osmosis and Diffusion and we decided that we were to test to see how it works by butting an egg in a liquid substance and see what happens. With my group we have decided that we would put the egg in corn syrup and in alcahol. So in the first day we have put the eggs in vinigar for 24 hours and waitined till the next day, the whole point of this is so that the shell out disolve and we would have only the egg inside it´s membrane. Then we would measure the weight and circumfrence. Then we would add 80ml of each of the liquids, in my case it was alcahol and one egg in one cup, and then cornsyrup and an egg in one cup. we would measure the same data each day for 3 days, the circumfrence, weight and how much liquid there was. In the end we would pop the egg and then we would see how each egg would look like in the inside. the data I colected in my table is the following:

Egg Lab (Rafael, Linn, Bianca)
Type of cell	Measurements	Day 1	Day 2	Day 3
Alcohol	Mass	Put the eggs in the vinegar for 24 hours	80 grams	74 grams
	Circumference		16cm	15cm
	mL		80 mL	65 mL
Corn Syrup	Mass	Put the eggs in the vinegar for 24 hours	74 grams	72.9 grams
	Circumference		16cm	16cm
	mL		80mL	78mL

Egg Lab (Carme, Vitor, Barbara)
Type of cell	Measurements	Day 1	Day 2	Day 3
Alcohol	Mass	Put the eggs in the vinegar for 24 hours	70 grams	63 grams
	Circumference		14cm	13cm
	mL		80 mL	15 mL
Corn Syrup	Mass	Put the eggs in the vinegar for 24 hours	75 grams	72 grams
	Circumference		15.5cm	14cm
	mL		80mL	75mL

Egg Lab (Girlany, Isabella, Bruno)
Type of cell	Measurements	Day 1	Day 2	Day 3
Alcohol	Mass	Put the eggs in the vinegar for 24 hours	70 grams	65 grams
	Circumference		14cm	15cm
	mL		80 mL	56 mL
Corn Syrup	Mass	Put the eggs in the vinegar for 24 hours	73 grams	72.4 grams
	Circumference		16cm	16cm
	mL		80mL	70mL

    Conclution: My opservations were that both my eggs were decreasing, it could have been that the substance inside the egg got out, and then the substance outside could also go in the egg, and also because the liquid could have evaporated, specially the alcahol. The substances were going from a high concentration to a low, which this could also be called passive transportation. Other groups that would have the same liquids (alcahol, corn syrup) like my group would have the same results.

Observations of each egg:

- Alcahol:  As the days would pass by
we would see that the egg would shrink, and the egg would get whiter and whiter, and also the yolk seemed to fell harder aswell. When the egg was opened we would see that the egg was hardened and it seemed like a boiled egg. We would also see that it smelled a lot like alcohol, so some alcohol must have entered through some of the eggs membrane.

- Corn Syrup: We would see that the eggs color would change into this golden color, and then we would see that the egg was getting harder completely including the yolk. The Corn Syrup outside would loose its consistesy make it more liquidy, but we supposed that the main corn syrup would get inside the egg. When we opened the egg we would see that the yolk was golden yet transperent, and also it was all hard, including the yolk, the textrue was like the inside of a gummy bear. It smellled a lot like corn syrup, but diluted.

Evaluation:

I think my group did a very good job, but sometimes we spilled a few materials and then we had to predict how much we spilled and then fill it back in. over all it was pretty well! :)

Try this at home its very cool!Warning: it will stink!
