DOES AN ORANGE FLOAT OR SINK?

Does an orange float or sink in water? We began by filling a large bowl of water and placing an orange in the water. The K4 kids discovered that the orange floats. Then we peeled the orange, removing the rind. Next we placed the unpeeled orange in the water and guess what? It started to sink!
The rind of an orange is full of tiny air pockets making it float on the surface!


SOIL ANALYSIS FOR PROJECT POLAR BEAR

Today the teams Eco Scientists 1&2 have determined different characteristics of our vegetable gardens in K4 and Grade 4 such as temperature, soil moisture, acidity or pH –level.

Also, they have started to record the size of the plants and their leaves to determine the expected growth and they’ve had a look at our Californian worms and how the vermicomposting is going.
