An Egg-cellent Activity
Introduction: In this lab your group will be given a RAW egg. A raw egg – one, singular,
uno. Your group has ONE chance to do the lab. If your egg breaks, cracks, or drops, so will
your grade! Treat this egg with kid gloves. Treat it as a baby. In fact, I urge you to name your
egg if you so desire. Eggbert, Roy Boy, Egg Sullivan – these are all acceptable names.
Remember, though, the egg cracks or breaks, your grade will reflect that, and you won’t be
able to continue with the lab. Speaking of the lab…
The lab is going to last for roughly a week. You will be manipulating the egg daily,
transferring from beaker to balance and back to beaker. YOU NEED TO BE CAREFUL! Your
grade and your group are depending on that.
DAY ONE:
Meet your egg. Take a couple of minutes to acquaint yourself with the egg. Shake hands, chat about the goings-on in
your life… It’s cool. I’m not judgin’…
1. Start by finding the mass of your egg. MAKE SURE THAT THE BALANCE IS MEASURING IN GRAMS (g)!!!!!
2. Turn on the balance, change the units to grams (g), if need be. Zero out your balance if you need to by hitting
the “tare/zero” button. GENTLY place your egg on the balance, wait until the display stops changing, and record
the mass of your egg (in grams) on the data table, under ‘Day One - Mass.’ P.S. Mass needs to be in grams –
grams… like the crackers, just spelled differently.
3. After you find the mass of your egg, put your egg in a clean cup. IF YOU DON’T WANT YOUR EGG TO BREAK
YOU WILL READ THIS BEFORE CONTINUING!!! For best results, you need your cup to ALMOST be parallel
with the ground. Then, SLOWLY roll your egg down the side of the cup. Remember, the goal is to be able to
actually finish the lab. We wouldn’t want a cracked egg on the first day. Get in the habit of putting your egg into
the cup this way.
4. Another group member should write the group members’ names, period, and egg’s name (if applicable) on a
piece of masking tape or on the cup directly. Use a sharpie to do this.
5. Next, pour enough vinegar into your beaker to just cover the top of your egg.
6. Put your egg on the designated spot assigned by your teacher.
7. Clean up your lab area, return the supplies to where they belong.
8. Wait 24 hours to begin the next step.
