On Thursday or Friday, students will be assigned an Osmosis "Egg"speriment. This is an at-home project. Your child should bring home a booklet we made in class to write observations and conclusions. They also will have a 2-page stapled paper that offers the instructions and has questions that must be answered.
This is a seven day experiment that will count as a test grade!
Mrs. Oddo's and Mrs. Compton's classes are due on December 8.
Mrs. Scarpinato's and Mrs. Malcolm's classes are due on December 9.
Materials:
Jar with a lid (wide mouth)
Jar with a lid (wide mouth)
raw egg (it can be white or brown)
white vinegar
clear corn syrup
string to use with metric measurement
booklet (made in class)
Day one: Measure the egg around the middle (metric only!). Record on the white paper. Place the egg in the jar and cover with vinegar. Cover the jar and place in a cool location, not the refrigerator. Observe and journal your observation for 3 days. (Day1, day2, day3). Try to plan on writing observations about the same time each day.
Day three: After your observation, pour off the vinegar, carefully remove the egg and measure. Note the measurement on the white paper. Rinse out the jar and place the egg back inside. Cover the egg with about 18cm of corn syrup. Answer question 1-3 under "What happened?" on the white paper. Write a conclusion about the effects of vinegar on an egg. Cover the jar and observe the egg for the next 3 days. (day 4, day 5, day 6)
Day six: After your observation, carefully pour off the corn syrup. The egg will be very slick! Measure the egg and note data on the white paper. Rinse out the jar and fill with tap water. Answer question 3 under "What Now". Carefully place the egg back inside. Answer question 4 under "What Happened?" Write a conclusion about the effects of corn syrup on the egg.
Day seven: Write your last observation. Pour off the water and measure one more time. Answer the remaining questions from the white paper. Write your conclusion about the effect of water on the egg.
After day seven has concluded students may turn in their completed white pages and the booklet that holds their observations and conclusions.
IF the egg falls and breaks, you have to start all over again! Be careful and enjoy the process of OSMOSIS!
