Check out these awesome pictures of our scientist friends in their safety goggles!
Are you ready to check the egg experiment? Let's observe!
I wonder what will happen tomorrow? Go ahead and check your hypothesis from yesterday. Were you right so far? Do you have a new hypothesis?
Ok scientists, it's time for another egg experiment! Do you think I can make an egg slide through a bottle? Find out below!
Wow! Can you believe that I squeezed an egg through a bottle? Isn't science cool! Why do you think the fire sucked the egg through the bottle?
(Parents, here is an explanation of the experiment from coolscienceexperimentshq.com)
How Does the Experiment Work?
Air pressure is the reason the egg to moved into the bottle without us touching it. Let’s explain exactly what happened:
- When we started the experiment, the air pressure inside the bottle was the same as the air pressure outside of the bottle.
- After we placed the burning paper in the bottle, the air inside the bottle began to heat up and expand.
- A few seconds after we placed the egg on top of the bottle, the fire went out and the paper stopped burning. This caused the air inside the bottle to cool down and contract.
- When the air contracts, the air pressure inside the bottle was less than the air pressure outside the bottle.
- Then the higher air pressure outside pushed the egg down into the bottle.
Now let's check back at the nest in Emma's wreath on her door.
Wow! I see more eggs than last time! Last time I saw three eggs. Now how many eggs are there? How many more were laid? There were 3 and now there are 5. 3 + what = 5?
2! 3 + 2= 5! There are 5 eggs now. Emma learned that one egg was laid each day.
Thanks for sharing Emma! If you find a bird's nest at your house please send me a photo or video so I can share it with the class! Enjoy the day scientists!
