The focus of this week’s science lessons will be to plan, carry out, write up and present a science experiment.
The aiom is to conduct and experiemnet, not just run a demonstration. So remember you will need an aim and an hypothesis. The first step will be to develop a purpose of the experiement. (To observe/check/identify … the efect of…) When planning yoiur experiment consider available equipment & materials.
To help determine the area of your experiment here are the relevant standards for each year level:
Yr 5 – Solids, liquids and gases have differentproperties and behave in different ways
prove behaviours and properties of different states of matter – options (popcorn; expanding gas, viscosity & density- oil & ice cube, separating salt & freshwater)
- recognising that substances exist in different states depending on the temperature
- observing that gases have mass and take up space, demonstrated by using balloons or bubbles
- exploring the way solids, liquids and gases change under different situations such as heating and cooling
- recognising that not all substances can be easily classified on the basis of their observable properties
Yr 6 – Changes to materials can be reversible, such as melting, freezing, evaporating; or irreversible, such as burning and rusting
prove a change is of a specific type – options ( borax & PVA/ bicarb & vinegar/ jelly/ condensation)
- describing what happens when materials are mixed
- investigating the solubility of common materials in water
- investigating the change in state caused by heating and cooling of a familiar substance
- investigating irreversible changes such as rusting, burning and cooking
- exploring how reversible changes can be used to recycle materials
