Science

Here are some photos of some of the work that we do for science.

Lately we have been learning about crystals.

For this experiment we made model of a geode.

We made molds out of grape fruit skin and plaster of paris.

Then we made a saturated solution by dissolving alum salt in water and adding food colouring.

We than poured the solution into the mould.

Then we waited for it to evaporate and form crystals.

Here is the result of the experiment.

Here is a real geode

Here we are looking through a microscope at bacteria that we grew in a petri dish.

We have also been looking at food science.

In these photos we were testing for starch in different foods by using iodine drops which is normally a dark orange colour. If there is starch in the food it turns black.

The other test was testing for fats by rubbing the food on brown paper.

If the food leaves a mark it contains fat.

Digging for fossils...

Testing different soils for erosion...

We have had a busy term and we are looking forward to the holidays in 12 days time.
