Title, Problem & Background.
Transcript: Errors: 1. The sugar water wasn't strong enough. 2. If the egg wasn't in a stable environment before the lab. Title, Problem & Background. Procedure and Data. Hypothesis: If we put an egg without a shell in salt water, then the egg will become hypertonic. Materials: 1 chicken egg plasma membrane 2 solutions of your choice Balance 1 glass jar/cup Vinegar 1 string/yarn 1 ruler 1. The substance that we put the egg in is the IV and DV was the result of what happened to the egg. 2. The control was the egg in the regular water and we needed it to compare the outcomes. 3. The egg swelled more in the water because the egg had more solution than the water. 4. The egg shrunk in sugar water because the water had more solution than the egg. 5. The results in questions 3 & 4 support our hypothesis because the egg swelled in water and shrunk in sugar water. 6. Osmosis is the diffusion of water. Osmosis is a passive transport method which moves water molecules from high to low concentration. 7. Passive transport doesn't require cell energy. Active transport requires ATP. Passive moves cells from high to low concentration. Data: Conclusion, Sources of Error and Works Cited. Procedure: 1. Take one chicken egg plasma membrane and place it into vinegar. Keep it in until the shell of the egg is off. 2. Once the shell is off, place the egg into a glass jar/cup of sugar water. Keep it in the sugar water for about 24 hours. 3. Take the egg out and measure it with the string/yarn, going all the way around the egg, then taking it off to measure the string with the ruler. 4. Repeat steps 2-3 if desired for more data. Conclusion: In this lab, we observed the effects of how an egg in sugar water reacts (hypotonic, isotonic, hypertonic). As seen in the data, the egg increased in both length and weight, until the 4th day, in which the weight dropped about 30 g. This lab proved our hypothesis wrong because the egg was hypotonic, and it expanded, which is why the weight and length increased. Egg Lab Presentation By: Noah, Daniel, and Hansen.

IV Egg in Sugar Water DV: Height and Weight of IV Control: Egg In Regular Water Constants: Type of Egg; Type of Environment; Temperature Title: Egg In Sugar Water. Problem: What will happen if we put an egg without a shell in water with dissolved sugar in it? Background Information: When you place an egg without a shell in sugar water for about 24 hours, the egg should shrivel up. Lab Questions.
