Bouncing a raw egg!

As it was Aprils Fools and Easter, we needed to do some experiemnts that combined both eggs and fooling the adults!!

Apparatus:
White wine Vinegar
Egg

Method:
Fill your glass full enough with white vinegar so that you can completely cover your egg.

Pop your egg in and look closely! See all of those bubbles on the surface - that's what's going to get our egg naked!
To get your egg entirely naked will take at least 24 hours! It's well worth the wait though, I promise!
Gently! Bounce your naked egg, yes, you read the correctly! Naked eggs bounce! Too much fun. Get started, right away! And remember to come back and read how it all works too!

What's going on?
Why does vinegar get our egg naked? Well, the first clue are those little bubbles that you can see! Those bubbles mean there's a chemical reaction going on! 
The shell of an egg is made of calcium carbonate (CaCO3). This reacts with the acid of the vinegar and causes bubbles of carbon dioxide to be given off. Eventually your whole eggshell will have been turned into carbon dioxide!
Luckily under the hard outer shell of your egg is a membrane. You can see through the membrane and even see the yolk moving around. Oh, and naked eggs bounce too!
WARNING: This is addictive and if you bounce it too hard you'll need to start over with a new egg! Oh, don't eat your egg! It's basically been pickled in vinegar!
More Fun Please - Experiment like a real scientist!
  • Does it have to be vinegar that you use, what other safe things could you try?
  • How high can you bounce your egg before it goes splat?
  • How long will your egg last for?

Volcano Experiment

Image
Aim: To see a reaction between an acid and base. Equipment: Washing up liquid, Vinegar, Cup or glass, Baking soda, Food colouring- Red & Yellow or orange Method: 1 Make sure your volcano is in the kitchen or outside 2 Add 2 tbsp full of baking soda 3 Add 1 tbsp of washing up liquid into the cup 4 Add a few drops of the food colouring 5 Quickly pour in just under a quarter of a cup of vinegar. Results: You will see foam rising/coming out Conclusion: Mixing the acid (vinegar) and the alkali (bicarbonate of soda) and releasing bubbles of carbon dioxide CO2. The washing up liquid is just there to trap those bubbles so it flows over the ‘volcano’ like real lava!

STEAM ED Open Day

 Sunday 25th September 2016 saw the first open day for a Steam Event. STEAM stands for S CIENCE, T ECHNOLOGY, E NGINEERING, A RT & M ATH. We had many participants and curious minds loving the concept of the extra-curricular activities that are fun. This site will be parent and kid friendly - hopefully we can communicate to best of both brains!!

Catapult

Image
The young ones today collaborated and designed in making their catapults. It is not an easy task- there are many ways of making catapults so working on the design was a challenge where the students had to agree on. After the design process, the students built their catapult and started firing their cannons!
