Science Week Day 4

Date: 22nd Mar 2018 @ 2:09pm

This morning we have had lots of fun with eggs. we made hypotheses about whether or not it is possible to crack an egg by holding the egg in your palm or between your thumb and forefinger. We found out that it wasn't. We then wrapped our eggs in cling film and applied force to one area of the gg and they cracked. We discovered that eggs have strong points where the pressure is equally spread so they don't crack.

Our next eggsperiment was to answer the question will an egg float in tap water? We discovered that they do t . We then aasked will an egg float in salty water? We made up a salt solution which we topped up with tap water. The egg sank through the tap water but when it reached the salty water at the bottom of the jug it floated. This is because salt water is denser that tap water.

The morning finished watching a fantastic sho called Journey To The Bottom of The Earth. 

After lunch we discussed healthy diets and thought about vegetarianism before designing science lab coats.
