Science Rotations

Science rotations are held every Friday afternoon where a students are given an opportunity to explore a broad range of science and technology. Each rotation will last up to 6 workshops. Workshop groups will be focussing on robotics, kitchen chemistry, garden biology, how the world works (physics) and healthy living. Our aim is to allow students to encounter a variety of scientific understandings through practical experiences and experiments.

Kitchen Chemistry 
Students will investigate the scientific processes and phenomena that occur in the everyday kitchen. They will make observations, form hypothesises, conduct experiments and discuss their hypothesises in light of the results. Students will learn about safety in a kitchen and how to conduct experiments successfully. The scientific concepts that will be investigated include; Density, states of matter, physical and chemical change, temperature and dehydration and food hygiene."

Robotics
In robotics, we will be using various robotics hardware including MindStorm NXT to foster the understandings of designing, building and programming of robots for specific purposes. The workshops will cover key areas in Science, Technology, Engineering, Mathematics and Literacy. The students will be introduced to a simple programming languages that will enable them to control robots and machines in different circumstances. Some of the concepts that will be explored will include energy efficiency, experiment with speed and distance whilst exploring the effects of friction, develop students’ research skills, making predictions and drawing conclusions, and excercise problem-solving and team-working skills. 

How the world works
This is a practical science exploration into the world of physics. In the first session we look at forces and explore how more strength can be obtained from the same type and the same quantity of building materials simply by choosing the correct shape. From here we go on to experiment with soluble substances investigating how a concentration of sugar, around a solid, creates a current due to a concentration gradient. We will look at how the motion is much less rapid if the concentrations on either side of a boundary are equal. We will also run experiments that investigate states of matter (solid, liquid, and gas), thermal expansion, air pressure, vacuums and misconceptions in science. For this we need glass jars and candles of different sizes so any donations of these would be greatly appreciated.

Garden Biology
This group will be looking at developing a plan for our Garden plot. We investigated why it is important to eat vegetables and what we want to achieve in our Kitchen Garden. We will discuss what type of vegetables we would like to grow and cook. We will also survey the students in both neighbourhoods to discover what the students would like us to plant and investigate what type of vegetables are in season and what we would like to grow. We will develop a planting calendar for the rest of the school year. Other areas we will investigate will be the resources we need and how we can create and use compost.

The Healthy Living

This group will be investigating what is healthy food and healthy living- what makes it healthy. We will develop the understanding that humans need to eat food for energy and essential nutrients. Students will taste and record the flavour of different foods, test ideas based on preconceptions about the colour and flavour of foods. We will develop students’ research skills and drawing conclusions, and also use problem-solving and team-making predictions.
