For this post we are going back to the beginning…of STEAM that is. So in honor of the “S,” how about a science experiment post to get your investigative juices flowing…
The Dissolving Egg Shell & Bouncing Egg Experiment
This experiment is simple, it involves a lot of observation but the results are really interesting to watch.
Reflection 1:
To start with, take time to reflect on what you think will happen when the eggs are put into the vinegar and water. Make a note of your reflection in a notebook or other recording device that you are able to keep your future reflections and comparisons in.
What You Need:
eggs
(we used raw eggs – 2 brown & 2 white)
vinegar
water
clear cups
What To Do:
1. Set up 4 clear cups.
2. Put 1 egg into each cup.
3. Add vinegar to 1 of each cup containing a white & brown egg.
4. Add water to the other 2 cups.
*eggs should be covered completely by each liquid.
5. Observe
Start of Experiment/Day 1:
Reflection 2:
What do you notice happening in the 2 cups?
Can you explain why these things are happening? (may require research)
A few hours later…
Reflection 3:
What do you notice about the egg in each cup?
Do you have a hypothesis as to why this is happening? (again, you may have to do a little research)
Write a prediction about what you think will happen to all 4 eggs at the end of 7 days?
Day 2:
Day 3:
Day 5:
Day 7:
End of Experiment – Day 7:
Reflection 4:
What has happened to the eggs?
Test your eggs to get more information by dropping them on a protected surface (adult approved of course).
What observations did you make?
And Now, The Science:
What is the chemical reaction that is taking place in this experiment?
Why does this happen?
How could you change this experiment to learn more about this reaction?
What other egg experiments have you done?
We’d love to have you share some of your reflections by leaving a comment!
Happy Experimenting!
