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.
- Hardboiled eggs
- A glass bottle
What you are going to do:
- Take a peeled hardboiled egg, a glass bottle and matches
- Light 2 matches and drop them into the bottle (make sure the inside of the bottle is dry, or you will extinguish the flames)
- Quickly put the hardboiled egg on top of the bottle
- 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?
Scientific Method on Enchanted Learning Printout (link)
“A scientific experiment involves many steps, including:
- 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.
- Gather Information – Do background investigation on the phenomenon you are interested in. Find out what is known about it already.
- Formulate a Hypothesis – Write a statement that predicts what may happen in your experiment based on your knowledge and data from other experiments.
- 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.
- Perform the Experiment
- Collect Data – Record the results of the investigation in a table or chart.
- Summarize Results – Analyze the data and note trends in your experimental results.
- Draw Conclusions – Determine whether or not the data support the hypothesis of your experiment.“
