At the end of the 1915 Gallipoli campaign during World War 1, Lance Corporal William Scurry saved thousands of lives with his one simple invention. As the ANZAC soldiers prepared to withdraw from the disastrous 9-monthlong Gallipoli campaign, Scurry came up with the idea of setting up a large battery of rifles that would discharge automatically…

Science curriculum and pedagogy offer ideal avenues for teaching young people the critical thinking skills they need to live in a post-truth world. Drawing on the theory of epistemic cognition, we present a selection of research-based pedagogies that have been shown to be effective in developing school students' understanding of knowledge and how…

Plants are often overlooked in favour of animals when teaching about living things. Focusing on familiar animals that share human characteristics helps young children learn about similar features. Examining plants for their differences, though, helps foster wonder. In the author's experience, children find it intriguing that plants need…

This article is written for primary and high school students, and provides a way to introduce kids to science and the concept of gravity.

Familiar toys can be used to scaffold young children's learning about basic physics as well as guide scientific inquiry. Teachers looking for resources to engage young children and develop science inquiry skills need look no further than the toy box. In this two-part activity, children first construct a Lego® car and use it to explore the effects…

An invitation to be part of a small research project with science teacher educators focusing on the Australian Curriculum--Science as a Human Endeavour strand provided an opportunity for professional learning in science for an early career teacher working with Year 1-2 students. This article explores how the use of students' photography of local…

Cognitive Acceleration through Science Education (CASE) on the Sunshine Coast is growing rapidly. It has expanded from one inaugural Year 8 class in 2012 to the current state of play with the involvement of over 3,000 CASE students from eleven Sunshine Coast State High Schools. It is being taught by more than seventy CASE teachers with…

This paper argues that, despite its difficulties, climate change can (and perhaps needs to) be taught rigorously to students by enquiry rather than through transmission and that such a method will enable students to make judgments on other issues of scientific controversy. It examines the issues and barriers to the teaching of climate change,…

A Smartphone is not only a mobile device that is used for communication but is also integrated with a personal digital assistant (PDA) and other technological capabilities such as built-in acceleration, magnetic and light sensors, microphone, camera and Global Positioning System (GPS) unit. This handheld device has become very popular with the…

Based on our experience of teaching physics in middle and senior secondary school, we have found that students have difficulty in reasoning at the microscopic level. Their reasoning is limited to the observational level so they have problems in developing scientific models of magnetism. Here, we suggest several practical activities and the use of…

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…

An integrated approach to assessment afforded pre-service teachers the opportunity to learn about a local sustainability issue through three learning areas: science and technology, the arts and studies of society and environment (SOSE). Three sustainability issues chosen by the pre-service teachers are presented in this paper highlighting the…

If students are to accurately model how scientists use written communication, they must be given opportunities to use creative means to describe science in the classroom. Scientists often integrate pictures, diagrams, charts, and other modes within text and students should also be encouraged to use multiple modes of communication. This article…

Proteins are a diverse class of biochemical macromolecules, including substances as (apparently) unrelated as silk and sinew, hair and horn, feathers and flagella, enzymes and epidermis, gelatine (jelly) and gluten and gore, spider web, meat and fish muscle. Yet they are unified by being polymers of amino acids. Discovery of the nature of proteins…

This article describes a simple, inexpensive, easy to conduct gel-electrophoresis activity using food dyes. It is an alternative to the more expensive counterparts which require agarose gel, DNA samples, purchased chamber and Tris-borate-EDTA buffer. We suggest some learning activities for senior biology students along with comments on several…
