My Question

• How will my egg change based on the liquid that it soaks in?

My Hypothesis

• In vinegar I thought it would shrink. In water I thought it would get bigger.In salt water I thought it would have bubbles on it. In food coloring I thought the color of the egg would change. In cooking oil I thought it would get smaller.

Procedures

1. Find the mass of the egg using a scale.2. Find the circumference of the egg

using a string and then a ruler.3. Write down observations of egg in data

table.4. Using a graduated cylinder, measure

200ml of vinegar and add to container.5. Carefully add egg to container and

leave for 24 hours.6. Repeat steps 1-5 but with salt water,

then food coloring, then a liquid of choice.

Day 1 Vinegar

* Today we put the egg in 200mL of vinegar. The egg was white, smooth,had a hard shell and oval.

Day 1 Mass Circumference

54g 14.1cm

Day 2 Water

* Today we put the egg in 200mL of water. The egg was yellow-white, slimey and oval.

Day 2 Mass Circumference

68g 15.2cm

Day 3 Saltwater

* Today we put the egg in 200mL of saltwater. The egg broke and we started with another one.

Day 3 Mass Circumference

68g 17cm

Day 4 Food Coloring

* Today we put the egg in 200mL of red food coloring. It got more yellow and bigger.

Day4 Mass Circumference

92g 18.5cm

Day 5 Cooking Oil

* Today we put the egg in 200mL Cooking Oil.The egg got bigger and more red. It was round and very slimy.

Day5 Mass Circumference

92g 20cm

Day 6 Finished

* Today we finished our egg experiment. Our egg got smaller after putting it in oil. The yolk was red-orange.

Day6 Mass Circumference

88g 18cm

Conclusion

• Some parts of our hypothesis were wrong but some were correct.We were correct in that the food coloring would change the color and correct that the water would make it bigger. The rest of our hypothesis was incorrect. In vinegar the egg shell came off a little. In water osmosis let water in so the egg got bigger. In saltwater osmosis let more water in and food coloring turned our egg red. In cooking oil osmosis pushed some water out of our egg making it a lot smaller.
