Students first get introduced to the concepts of pure substances and mixtures, and the particle theory by doing a photo-hunt for matter in their home and exploring the world of particles through images from electron microscopes. Then students design their own experiments following the scientific method to answer questions about the properties of matter. Scaffolding can be used to encourage gradual release of responsibility for choices of materials and methods. In a second activity, students are required to design and build a water purifying system using basic materials to separate the various ‘pollutants’, with a focus on disposal of the ‘refuse’ of the experiment in an eco-sensitive manner.
In this unit plan, students learn to name the six different kinds of simple machines and how they make work easier and more enjoyable for people. They will also learn to design, build and test an... read more
The students will be given images of different locations that show before human impact on the natural environment, and how nature affects a similar location (e.g. flood). They will begin using the... read more
