Science Experiment: Egg in Vinegar

image
Cover the egg in vinegar.

Cover and leave in the fridge for one week (change vinegar after the first 24 hours)
image
Carefully remove the egg from the vinegar.
image
Gently wipe off the shell with a tissue.

I am not entirely sure if this is supposed to happen, especially since it then dripped slightly from this bit. Perhaps we weren’t careful enough. Squiggle said the shell looked and felt like sand as it rubbed off.
image
The egg is now quite squishy and rubbery!
image
Squiggle enjoyed bouncing it around the table.
image
Of course it is still an egg so therefore not entirely indestructible! When it finally broke from all the (over-enthusiastic) bouncing, the shell felt like latex but gritty and was almost whole. Squiggle found this very interesting.

Failed Science Experiment

We tried another experiment from the Eco Science kit yesterday. The idea was to discuss pressure and demonstrate how a submarine works. The instructions stated to fill the dropper 2/3 full then drop it in the bottle full of water. With the right amount in, the dropper should sink and float and the bottle is squeezed and released.

Preparing the experiment

However it didn’t quite go according to plan unfortunately as the dropper seemed to go from too much water to too little in just one drop. After a frustrating half hour or so of emptying and refilling the bottle in order to get the dropper out and try again it got rather tedious so we finally gave up.

She then enjoyed designing her own experiment and exploring the resources her own way instead.

She was very disappointed it did not work out and we were both rather frustrated by the end. Think we would rather have given this one a miss!

Cooking Eggs

Squiggle has never been keen on eating eggs before, but in conversation today, the topic came up about different ways to cook eggs and she seemed really enthusiastic to try this at home. She was very interested in helping to cook the eggs in various different ways. This occasion included scrambled egg, hard boiled, soft boiled and fried egg. Even better, she happily tasted them all too. She also had fun making an egg and red pepper sandwich, which she also ate.

Squiggle really enjoyed this science activity and it was of educational value in various ways. I think possibly on average it may be more beneficial for younger children than it states on the box (it says ages 8 plus, my daughter is 5), although this is for safety reasons rather than the age it is aimed at for educational purposes. In other words supervision may be required.

My main gripe was the possible promotion of fizzy drinks to children but it might have worked with a substitute item such as a cardboard roll, we didn’t try this because Squiggle wanted hers to be similar to the picture on this occasion. Other than that it was a simple but fun activity that she got alot out of doing.
