For this Mini Spark we are going back to the beginning…of STEAM that is. So in honor of the “S,” try this egg science experiment. It take 7 days to do, so it might be one you try at home. You can also talk to your teacher about setting it up at school.
Spark your thinking!
1. Set up your STEAM mini spark recording page: #16: Eggstraordinary Experiment
2. This mini spark teaches you how to do the The Dissolving Egg Shell & Bouncing Egg Experiment. This experiment is simple, you place eggs in water and also eggs in vinegar. It involves a lot of observation and the results are really interesting to watch. You will set up your experiment and do 4 reflections on your recording page.
3. 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 on your recording page.
4. Gather your materials. Take a picture and add it to your recording sheet.
What You Need:
- eggs
- (we used raw eggs – 2 brown & 2 white)
- vinegar
- water
- clear cups
5. Set up your experiment. Take a picture and add it to your recording page.
- Set up 4 clear cups.
- Put 1 egg into each cup.
- Add vinegar to 1 of each cup containing a white & brown egg.
- Add water to the other 2 cups.
- The eggs should be covered completely by each liquid.
- Observe
The Dissolving Egg Shell & Bouncing Egg Experiment
Day 1 Reflection 2:
What do you notice happening in the 2 cups?
Can you explain why these things are happening? This might require some research to answer. Add your responses to your recording sheet.
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?
You can read the info at the top of this page to help you answer these questions.

This video explains some of the science. Watch it to help you answer the questions above.
6. Share your STEAM mini spark recording page with your teacher/EY coordinator

See if you can do this one in your head…
Rising to a height of 85 meters in the Norwegian landscape, Mjøstårnet holds the title of the tallest wooden building in the world, constructed primarily from timber sourced from nearby forests. However, not long ago, towards the close of the 20th century, engineers believed that erecting a wooden structure taller than six stories was unfeasible. What, then, are the differences between wooden constructions like this and skyscrapers made of steel and concrete? Stefan Al explores this question.
Are you ready for a fun cardboard box building challenge? Grab a box, scissors and tape, and a few other item, and let’s get started! With just these three materials, you can create,well, anything you want!
In the STEAM mini spark, learn about inventors. The USPTO collection cards show goofy caricatures of inventors! They’re made to celebrate all kinds of inventors from different backgrounds.
Since the “T” in STEAM stands for technology, it seemed only right to add a post about the code.org video series. Get started on this mini spark to join in on the coding fun and who knows, maybe even begin your career in the computer sciences!
