Different materials can be combined, including by mixing, for a particular purpose (ACSSU031)
investigating the effects of mixing materials together
Declarative
Everyday materials can be physically changed in a variety of ways (ACSSU018)
exploring how materials such as water, chocolate or play dough change when warmed or cooled
This PowerPoint is designed to be an introduction to this topic. It is in a printable format to make its use in the classroom flexible, if printed should be laminated due to the nature of the investigation. The task card includes hands on investigation into the effects of mixing materials together. Having this as the first lesson creates an example for the students to refer back to when completing further tasks. The investigation on the task card has been taken from The Usborne Big Book of Science Things to Make Do.
Declarative
Procedural
Mixing materials together can cause many different reactions.
Mixing bicarbonate of soda with vinegar creates carbon dioxide.
Observe and discuss outcomes of investigation.
For the Teacher
Class discussion:
Cooking with mum and dad and its relationship to mixing
Bath time, Bubble bath into their bath.
Chocolate milk, syrup or milo
What other things can you think of?
Today’s Experiment:
Small groups
Hand out task cards
Go through cards together as a class, answers any questions.
Designate one student from each group to get the materials.
Have students perform investigation and provide help when required
Children can use a digital camera to take photos throughout investigation and post on class wiki. This will introduce the concept of recording data..
Students then participate in Think, Pair and Share. This can be verbal or written.
- What happened?
- Why do you think this happened?
- What caused this reaction?
Class then regroups to discuss the answers to Think, Pair and Share.
A simple scientific explanation should be given e.g.
“The foam that pours out of the jar is formed by a simple chemical reaction. When the vinegar and bicarbonate of soda mix, they make lots of tiny bubbles of gas (carbon dioxide). The bubbles churn up the dishwashing liquid making lots of foam.” Ursbourne, 2012.
