Winning projects details on our FUN! Science page

Investigations / Projects (Intermediate to Senior entries)

  • Acidic and basic solutions - how are they produced; how can they be neutralised; used to modify soil acidity; in lakes; in food; around the home. 
  • Recycling plastics; different types of plastic; different uses.
  • Chemical change and the factors that affect the rate of reaction (eg heat, light, catalysts, temperature).
  • The effects of salts on the freezing point of water and other liquids. 
  • Turn a digital multimeter into a data logger...use salt sensors, light sensors, conductivity, etc.
  • Chemical principles in everyday life
  • Investigate the factors that affect the rate and the size of growing crystals
  • How safe are school lunches? - how hot does your lunch box get?
  • Testing of consumer products such as glues, antiseptics, mouthwash, detergents, paper towels, water filters.
  • Chemical reactions that produce or require energy 
  • Experimenting with microbial degradation of petroleum
  • Compare the surface tension of various liquids 
  • Effects of sunlight on rubber, ink, paper.
  • Design and test a simple datalogging device for chemistry experiments.  Perhaps a good PICAXE project?
  • How catalysts and their use in industry
  • Milk Glue is amazingly strong stuff!
  • How do acids react with different metals under various conditions 
  • Rainwater analysis for pollutants using samples from variuos locations

  • Effects of temperature on density of gases 
  • Connect a Casio graphics calculator to a simple data logger for science and maths classes.
  • What effects do different amounts of exercise have on the production of carbon dioxide in humans? 
  • Analyze soil samples for their components, water holding capacity, pH, and minerals 
  • Stalagmites - create artificial limestone caves!
  • Types and efficiencies of fire extinguishers
  • Identify different metals by the colour of flame when they burn 
  • Electroplating different metals and uses at home and in industry
  • A chemical analysis of the extraction and make up of DNA
