Science Wrangling: Go Suck An Egg

 

I really didn’t think this would work…but by golly, it did!

For the most part. We should have used a bigger bottle, but I just didn’t have any around. This is a really fun experiment to do with the kids, and to teach them about the properties of fire and vacuums.

What’chu Need:

  • Hardboiled eggs
  • Matches
  • A glass bottle

What you are going to do:

  1. Take a peeled hardboiled egg, a glass bottle and matches
  2. Light 2 matches and drop them into the bottle (make sure the inside of the bottle is dry, or you will extinguish the flames)
  3. Quickly put the hardboiled egg on top of the bottle
  4. Watch as the egg gets sucked into the bottle!

 

 

 

 

So, what is happening in the bottle?  How did you create a vacuum in the bottle?  How did the fire affect the oxygen levels in the bottle?

A scientific experiment involves many steps, including:

  1. Observe, State Experimental Questions – After observing a phenomenon, you may wonder what is happening, and what caused it to happen. Write down your observations and your questions.
  2. Gather Information – Do background investigation on the phenomenon you are interested in. Find out what is known about it already.
  3. Formulate a Hypothesis – Write a statement that predicts what may happen in your experiment based on your knowledge and data from other experiments.
  4. Design an Experiment to Test Your Hypothesis – Determine a logical set of steps to be followed in your experiment.
    • Independent/Experimental Variable – Determine or guess which factors could affect the phenomenon you are studying. The experimental variable is the one variable the investigator chooses to vary in the experiment.
  5. Perform the Experiment
  6. Collect Data – Record the results of the investigation in a table or chart.
  7. Summarize Results – Analyze the data and note trends in your experimental results.
  8. Draw Conclusions – Determine whether or not the data support the hypothesis of your experiment.
