Core Skills Analysis
Science
- BJ identified three scientific fields—otolaryngology, prehistory and physiology—by connecting each scientist with a specific area of research.
- BJ traced how sound travels and learned that the ears and brain work together in hearing, including how a cochlear implant supports people with hearing loss.
- BJ investigated cohesion and adhesion, recognizing that water can attract other water molecules and stick to different surfaces.
- BJ used predictions, observations and comparisons in the potato experiment to begin explaining osmosis and water movement through semi-permeable cell membranes.
History
- BJ explored deep time and understood that human history occupies only a very small part of Earth’s long history.
- BJ learned that prehistorians, such as John Mulvaney, study evidence about ancient human life before written records.
- BJ used portraits of scientists as historical clues, considering how an image may communicate information about a person’s life, interests or profession.
Language Arts
- BJ practiced interpreting visual information by examining portraits and using details to infer meaning.
- BJ encountered and applied specialized vocabulary, including otolaryngologist, physiologist, cohesion, adhesion, osmosis and semi-permeable.
- BJ developed evidence-based explanation skills by making predictions and comparing them with observed changes in the potato slices.
Mathematics
- BJ compared the relative scale of human existence with Earth’s enormous history, building early proportional and timeline reasoning.
- BJ practiced organizing experimental evidence by comparing potato slices placed in fresh water with those placed in salty water.
- BJ engaged with concentration as a scientific comparison, considering how differing amounts of dissolved salt affect water movement.
Visual Arts
- BJ learned that portrait composition and visible objects can communicate clues about a subject’s profession, interests and identity.
- BJ connected artistic observation with scientific inquiry by interpreting portraits of Australian scientists as sources of information.
- BJ considered how images can tell part of a person’s story without using written text.
Tips
Tips: Help BJ create a labeled sound pathway diagram from the source of a sound to the brain, then compare ordinary hearing with how a cochlear implant assists hearing. Make a deep-time timeline using a long strip of paper, placing Earth’s history at one scale and human existence at the very end. Repeat the potato investigation with several salt concentrations, recording predictions, texture changes and conclusions in a simple results table. Finally, invite BJ to design a portrait of a scientist using objects, clothing or symbols that reveal the scientist’s work, followed by a short explanation of each clue.
Book Recommendations
- The Magic School Bus Explores the Senses by Jill Colella: An accessible introduction to how the senses, including hearing, help us understand the world.
- A Really Short History of Nearly Everything by Bill Bryson: A child-friendly exploration of Earth, life and human history that connects with BJ’s study of deep time.
- The Water Princess by Susan Verde: A moving story that highlights the importance of water and can support further discussion about water’s properties and human needs.

- Record potato predictions and results in a table with columns for water type, appearance, texture and conclusion.
- Draw a deep-time timeline showing Earth’s history and the much smaller span of human existence.
