Core Skills Analysis
Science
- BJ learned how sound travels through the ear and is processed by the brain, including how a cochlear implant can support people with hearing loss.
- BJ identified cohesion as water molecules attracting one another and adhesion as water sticking to other surfaces.
- BJ was introduced to osmosis by observing how potato slices changed in fresh water and salty water as water moved through semi-permeable cell membranes.
- BJ practiced scientific investigation skills by making predictions, observing results, comparing conditions, questioning outcomes, and drawing conclusions.
History
- BJ explored the idea of deep time and recognized that human history occupies only a very small part of Earth’s long history.
- BJ learned that Professor John Mulvaney studied Australia’s ancient human history as a prehistorian.
- BJ used portraits of scientists as historical clues to connect people’s work with their contributions and areas of expertise.
Language Arts
- BJ practiced interpreting visual information by examining portraits for clues about a person’s life, interests, hobbies, and profession.
- BJ encountered and used subject-specific vocabulary, including otolaryngologist, prehistorian, physiologist, cohesion, adhesion, osmosis, and semi-permeable.
- BJ developed explanation skills by connecting observations from the potato experiment with scientific ideas about water movement.
Tips
Tips: Help BJ create a simple sound diagram showing the journey from an outside sound to the ear and brain. Make a deep-time timeline using a long strip of paper, placing Earth’s formation and human history at scale. Repeat the potato investigation with several salt concentrations, recording predictions and measurements in a results table. BJ could also design a portrait of an imaginary scientist, adding visual clues that reveal the scientist’s research interests and profession.
Book Recommendations
- The Way We Work by David Macaulay: An illustrated explanation of how the human body functions, connecting with hearing, cells, and body regulation.
