This term in Room 13 we are focusing on science and the material world - looking into the changes different objects go through when combined or mixed with something else. These past couple of weeks we have been creating naked eggs!
We placed regular raw eggs into vinegar and let them soak over night and then after 24 hours we observed the changes that had occurred and changed the vinegar! (the eggs was starting to feel really slimy). We then left the egg to sit in the vinegar for another 48 hours and when we came back to them the shells had dissolved and the membrane around the outside of the egg was still there so we could see inside of it! We had a play with the eggs and found out they had become bouncy and didn't break if we were careful with them, we then let them soak in water for about a week! When we took them out the water we found that they had absorbed some of the water and were even bigger than when we started! We then had some fun playing with the eggs and seeing how high we could drop them from before they broke!
