At Bridekirk we are very in touch with nature and we love learning about plants and animals.
Primary Three have their own Frogspawn which we are studying as part of the Year 4 Animals and their Habitats module. We are going to research exactly what our Future-Frogs will need in their habitats during the different stages of their life-cycle: Are the needs of a tadpole the same as the needs of a frog?
Note: The tadpoles will be released back into the exact pond they came from!
Animals Including Humans: Teeth!
Year 4 have been learning about how to look after teeth. We discovered that the shell on the outside of eggs is very similar to the enamel on our teeth. So, we put some eggs (hard boiled!) in different types of liquid.
We watched the eggs over a number of days and recorded any changes to the surfaces of the eggs.
We found that the egg in the orange juice had the most damage to the surface.
We thought very hard about what was different about the orange juice and came to the conclusion that it was the highest in sugar of all of our drinks. This led us to believe that drinks such as orange juice would be the worst for our teeth out of the selection.
Moral of the story: if you have to drink sugary drinks, always use a straw!
We love making circuits!
In this particular experiment we were testing different conductors and insulators. We then tried to group different objects into conductors and insulators and then used these to make predictions about whether the next object would be a conductor or an insulator.
In the bottom left group, all of their metal objects so far had be great conductors, would their metal key be the same?
