Eggsperiment

1. What happens to an egg when it is put into vinegar for a few days? 2. What happens if it is then put into corn syrup for a few days? 3. What happens if it is then put into water? 4. What is osmosis? 1. I think the egg will swell up and get smaller. 2. I think it will get even bigger in corn syrup. 3. I think the egg will return to it's normal size in the water. 4. I think osmosis is when something soaks up water. •** Clean jar with lid Measurement of circumference of egg: 14 cm
 * Questions:**
 * Hypothesis:**
 * Materials:
 * •** Egg
 * •** White vinegar
 * •** String
 * •** Ruler
 * •** Clear corn syrup
 * •** Journal
 * Day one, vinegar:** (date) 2/22/09
 * Observations:**
 * •** When I poured the egg in the vinegar the egg got covered in bubbles. (12:30 P.M.)
 * •** After a few hours the egg kept bubbling and made a foam at the surface. (5:15 P.M.)

 * Day two:**
 * Observations:**
 * •** When I woke up this morning I saw that the egg was orange. The vinegar dissolved the shell. All that was left was a soft, gooey membrane. (8:20 A.M.)

•** In the morning I saw that the egg did not change much. It only got a little more orange. (8:20 A.M.) Day four: Carefully remove the egg from vinegar.** Measurement of circumfrence of egg**:** 19 cm The egg has gotten 5 inches bigger. Day five: Observations: •** When I looked at the egg I saw that it was dented. It looked almost flat. (8:20 A.M.) Day six: Carefully remove the egg from the corn syrup and measure.** Measurement of circumference of egg:15 cm The egg has lost all liquid. The liquid came out through the membrane but the corn syrup was to thick to go in the membrane. Observations:** Day seven: Carefully remove egg from water and measure.** Measurement of circomference of egg: 20 cm •** The egg has fully recovered and is in the shape of a real egg. (8:20 A.M.) Results:** Measurement egg before experiment: 14 cm Measurement of egg after being in vinegar: 19 cm Measurement of egg after being in corn syrup: 15 cm Measurement of egg after being in water: 20 cm 1. **What happened to the egg when you put it in the vinegar? Why?** The vinegar ate the shell. It also soaked up vinegar because liquids can go through the membrane. The egg got dents in it. All of the vinegar went out of the membrane but the corn syrup was to thick to go through the membrane. The egg reformated because it soaked up water. No liquid came out because no corn syrup went in. Osmosis is liquid transfering through a membrane.
 * •** Throughout the day, the egg got more and more orange. (8:20 A.M- 12:00 P.M
 * Day three:**
 * Observations:
 * •** The membrane seems to have become rough. (6:20 P.M.)

 * What has happened to the egg?**
 * Observations:**
 * •** The corn syrup has stuck to the egg. it made a thick temperary shell. (4:40 P.M.)
 * •** The egg has started to float. (5:10 P.M.)
 * Photo(s):(top view, side view)
 * •** The egg has squashed even more throughout the day. (4:30 P.M.)
 * Photo(s):(top view, side view)
 * What has happened to the egg? Why?**
 * Carefully put the egg back into the clean jar. Cover with water.
 * •** The egg is slowly soaking up water. (8:20 A.M.)
 * •** You can see the egg is reforming. (4:20 P.M.)

 * Conclusions:**
 * 2. What happened when you put the egg in the corn syrup? Why?**
 * 3. What happened when you put the egg in water? Why?**
 * 4. What is osmosis?**
