Core Skills Analysis
Computer Science and Coding
During Open Lab visits at Cabramatta Library on February 7 and Bonnyrigg Library on February 28, Rosalie continued building coding skills from earlier visits. Rosalie placed a blue LEGO brick in front of a sensor and explored how the camera could detect its colour as a trigger. Rosalie then coded an alarm-like response using light and sound, learning how an input from a sensor could make a programmed output happen. This activity introduced Rosalie to the logic of event-based programming: when a system detects a chosen condition, it can carry out a specified action.
Engineering and Robotics
Rosalie programmed a robot car and set its movements, exploring how instructions could guide a physical machine. By changing the movement settings, Rosalie practised connecting code with the car’s real-world behaviour. Rosalie also experimented with LEGO to make a pulley system, investigating how connected parts could work together to move or lift something. These activities gave Rosalie practical experience with designing, building, and testing ideas through robotics and simple mechanical systems.
Science
Rosalie explored a colour-sensing process by placing a blue LEGO brick in front of a sensor and using the camera’s detection of that colour as the basis for a response. This provided an opportunity to observe how a sensor can gather information from its surroundings and how that information can be used to trigger light and sound. While experimenting with the LEGO pulley system, Rosalie also encountered a practical example of how a mechanism transfers movement. Together, these activities supported hands-on exploration of sensing, cause and effect, and mechanical motion.
Tips
Tips Build on Rosalie’s sensor coding by inviting Rosalie to choose other coloured objects and predict which ones will trigger the light-and-sound response, then test and record the results. Make a simple “sensor-to-action” flow chart showing the colour detected, the code condition, and the alarm response. For robotics, set up a small taped route for the car and have Rosalie plan a sequence of movements, then adjust the code after each test. Extend the pulley exploration by building a LEGO structure that moves a small, lightweight object and drawing how the parts work together.
