Exploring Density Through Investigation

Our Year 7 Science students recently explored the fascinating concept of density through a hands-on investigation creating their own density towers.  Before beginning the practical activity, students researched the density values of a range of everyday liquids and predicted the order in which they would layer.  They then carefully poured each liquid into a measuring cylinder, observing how substances with different densities formed distinct layers.

The investigation also highlighted the importance of scientific technique.  Students discovered that when liquids were poured too quickly or care was not taken, the detergent interacted with the fats in the milk and oil, causing the layers to mix rather than remain separate.  This provided an excellent opportunity to discuss how careful observation and precise methods are essential in scientific investigations.

To explain their results, students applied the particle model of matter, using their understanding of how particles are arranged and packed in different substances to account for the layering of liquids and the interactions that occurred when the mixtures were disturbed.

This engaging practical allowed students to connect scientific theory with real-world observations while developing valuable skills in prediction, experimentation, observation and scientific explanation.

Junior Thinkers Conference 

On Friday, 31 July, a group of Year 8 students travelled to Camberwell Grammar School for the Junior Thinkers Conference.  The guest speaker, Julie Arliss, presented a wide range of thought-provoking topics, including Do I Have a Soul?, The Scientific Origins of the Universe, Does Bad Luck Make You a Bad Person?, and a debate exploring whether patriotism is a virtue. She encouraged us to think critically and consider different perspectives. The conference aimed to inspire students to ask questions, justify their opinions with evidence, and participate in a variety of discussions.

Throughout the day, the students listened to two presentations before breaking into groups with students from other schools to discuss the question of whether bad luck makes you a bad person.  They answered comprehension questions based on Jean-Paul Sartre's short story, The Wall, and explored situations where bad luck can affect the outcome, even when people's motives are the same.  As a group, we shared our responses and reflected on the different perspectives raised during these discussions.

Later, we observed a debate between Julie Arliss and a Camberwell Grammar student on the topic of whether patriotism is a virtue, with students invited to participate and share their own opinions.  Through this experience, we were challenged to deepen our thinking and look beyond simple answers. It was an engaging and enjoyable day that helped develop our critical thinking and discussion skills while inspiring us to continue asking big questions about the world around us.
