INTEGRATED - Bread Experiment

As part of our exciting Science Integrated Unit, our classrooms have been buzzing with curiosity as we explore the fascinating world of native flora. Much of our focus has been on understanding the unique features and survival adaptations of eucalypts.

While we are still currently observing our ongoing seedling experiment, this week we kicked off a brand-new scientific inquiry: Does eucalyptus oil prevent mould growth on bread?

To find out, students worked in small groups to act as real scientists. They collaborated to:

• Discuss and identify the variables required to ensure a completely fair test
• Write a detailed investigation plan

• Formulate thoughtful predictions 

   

With plans in hand, the experiment officially started this week! Each group set up two slices of bread: one acting as our control with a few drops of diluted cooking oil, and the other treated with diluted eucalyptus oil.

Students are now conducting daily monitoring to observe, track, and record any changes or growth. We can’t wait to see if our predictions match the results! Ask your young scientist what they think will happen to the bread.

MATHS - Place Value Scavenger Hunt

We have begun our maths unit looking at place value. As a part of this unit we are looking at the difference between a digit and a number and ways we can partition numbers based on place value to see what makes up a number e.g. 4365 = 4000+300+60+5

Our unit will then dive deeper into ways that numbers can be renamed, rearranged and regrouped, before extending our knowledge of place value to tenths and hundredths and using pictorial representations and decimal notation to record these values. 

As an introduction to this unit we took part in a scavenger hunt trying to identify and record numbers that were represented using pictures, expanded notation as well as standard and non-standard representations of numbers. Here are some pictures from the hunt.
