In this Grade 8 Food Science investigation, students explored the science of popcorn by examining how heat causes physical changes in food. Working in groups, students predicted, observed, and recorded what happened as popcorn kernels were heated, linking their observations to concepts such as moisture, pressure, and energy transfer.

Students investigated why popcorn pops, discussed the factors that affect the process, and compared their results with their initial predictions. Through hands-on experimentation, they developed their scientific observation skills while gaining a deeper understanding of how science influences everyday foods and cooking processes.

In this Grade 7 Science investigation, students explored the properties of polymers by creating their own slime using a combination of common household materials. Working in groups, they carefully measured ingredients, followed scientific procedures, and observed how different substances interacted to produce a new material with unique properties.

Throughout the activity, students investigated concepts such as viscosity, elasticity, and chemical change while recording their observations and testing the behaviour of their slime. The lab provided a fun and engaging introduction to materials science, encouraging students to think critically, work collaboratively, and apply scientific knowledge through hands-on experimentation.

In this Grade 7 Science project, students designed and built solar ovens using pizza boxes, aluminium foil, plastic wrap, and black paper to capture and retain heat from the Sun. The challenge allowed students to investigate how solar energy can be transferred and converted into thermal energy.

To test their designs, students used their solar ovens to make s’mores, observing how sunlight could generate enough heat to melt chocolate and marshmallows. Through this hands-on activity, students developed their understanding of energy transfer, renewable energy, and engineering design while applying scientific concepts in a practical and engaging way.

In this Grade 7 Mathematics project, students explored integer operations by creating colourful and informative displays that demonstrated their understanding of positive and negative numbers. Each student selected an integer and designed a visual presentation that incorporated mathematical calculations, patterns, and real-world applications.

The project encouraged students to reinforce their understanding of integer addition, subtraction, multiplication, and division while developing creativity and presentation skills. By combining mathematical accuracy with artistic design, students were able to communicate their learning in an engaging and memorable way.

In this Grade 8 Science engineering challenge, students investigated the principles of buoyancy by designing and constructing model cargo ships using a range of materials. Before building, each group created detailed plans and blueprints, carefully considering how their design would maximise stability and carrying capacity while remaining afloat.

Students then tested their prototypes by adding increasing amounts of cargo and observing how factors such as shape, weight distribution, and displacement affected performance. Through the design, testing, and redesign process, students developed a practical understanding of buoyancy, density, and engineering design while strengthening their teamwork, creativity, and problem-solving skills.
