Classifying the natural world

In science this week, we’ve studied the idea of scientific classification. Here’s Patrick’s write up of our class attempt at classifying the natural world.

Faith suggested a dotted line between living and non-living because the remains of animals and plants are preserved in fossils. Perhaps wooden objects cross over in the same way. And to complicate things further, we talked about how boundaries between living and non-living may blur as artificial life develops.

We also spent a pleasant half-hour in the nature garden, sketching different organisms and plants and then classifying them into the five animal kingdoms etc. Here are Olivia’s sketches and some photos.

Mould experiments

Our mould experiments are up and running!

We’ve followed a scientific process:

  • Researching existing knowledge
  • Choosing a scientific question to investigate (one which we can’t already answer)
  • Designing the experiment
  • Writing down our method so that the experiment could be repeated.

We’re hoping to invite parents to a quick presentation of the results in a couple of weeks’ time.

Here are the seven investigations underway:

  1. Will mould grow faster on white or brown bread?
  2. Will mould grow faster on bread or toast?
  3. Will mould grow under water?
  4. Will liquid soap slow or stop the growth of mould on bread?
  5. Will an antibacterial product (Dettol) slow or stop the growth of mould on bread?
  6. Will mould grow on bread wrapped in clingfilm (and therefore not exposed to air)?
  7. Will mould grow faster on fruit or bread?
