Oz-e-science - Chemistry

In this unit, students explore everyday objects, the materials they are made from and their observable properties through hands-on scientific investigations. They develop scientific inquiry skills by observing, identifying, comparing, ordering, predicting, sorting and recording while investigating concepts such as length, mass, capacity, texture, flexibility, shininess, transparency and squishiness. Through practical exploration and simple experiments, students build their understanding of how materials behave and strengthen their early scientific thinking and investigation skills.
