This article is the second in "Teaching Science's" "Try This" series. These hands-on activities are designed especially for early childhood students to encourage their natural curiosity and promote development of scientific thinking. In this activity, the problem-based learning approach means that the children are engaged in a…

With one week to go, Year 12 chemistry made their final practical an event to be remembered. We decided to take that infamous Periodic Table to the next level, transforming it into an edible table! Armed with 114 biscuits, multiple tubs filled with coloured icing, plastic knives, and gloves and "Professional" piping bags, we converted the science…

Plain flour has a lot of chemical energy packed into it. When the flour is in a clump or pile it does not ignite although it may blacken. This is because there is not enough flour exposed to the oxygen in the air. Aerosolising the flour exposes it to much more oxygen allowing a self sustaining combustion reaction to occur when an ignition source…

A practical exercise for developing a simple cost-effective solar ultraviolet radiation dosimeter is presented for use by middle school science students. Specifically, this exercise investigates a series of experiments utilising the historical blue print reaction, combining ammonium iron citrate and potassium hexacyanoferrate to develop an…

Australia's Early Years Learning Framework and leading international researchers argue for more intentional and purposeful teaching of science in the early years. This case study of exemplary practice illustrates intentional teaching of science materials which opened-up learning opportunities in literacy and number. Student-led hands-on…
