Topic 3! Flashcards
Year Level Statement 1
In Year 1 students learn that everyday materials can be physically changed in a variety of ways.
Year Level Statement 2
In Year 2 students learn that different materials can be combined for a particular purpose.
Year Level Statement 3
In Year 3 students learn that a change of state between solid and liquid can be caused by adding or removing heat.
Year Level Statement 4
Year 4 students learn that natural and processed materials have a range of physical properties that can influence there use.
Year Level Statement 5
Year 5 students learn that solids, liquids and gases have different observable properties and behave in different ways.
Year Level Statement 6
In Year 6 students learn that changes to materials can be reversible or irreversible.
Year Level Statement 7
Year 7 students learn that mixtures – including solutions – contain a combination of pure substances that can be separated using a range of techniques.
Constructivist Theory
Constructivist Theory is based on the premise that;
Learners must actively construct their own knowledge
Learners prior knowledge is influential in how learners construct new knowledge
Construct their own Knowledge
Knowledge is an active process.
Students must engage and interact with their environment.
Social and physical interaction are important.
Student developmental level set limits on their learning at that given point.
Developmental Levels
Stage 1: Sensorimotor (birth- 2 years)
Stage 2: Pre-operational (2 years – 6 years)
Stage 3: Concrete operational (6 years – Teen years)
Stage 4: Formal operational (12+)
Prior Knowledge
Children come to school with preformed ideas that help explain the world around them.
The ideas make sense and are logical to the children and are usually strongly held.
These ideas are referred to as misconceptions, preconceptions, alternative conceptions, alternative frameworks, pre-instructional concepts.
Physical Changes
Physical Changes are reversible. An example of physical change is what happens when we increase the temperature of a solid such as ice; it melts.
Chemical Changes
Processes where new substances are formed and which cannot be reversed to remain the original substance is called “Chemical Changes”
True or False?
Boiling point is the highest temperature a substance can reach
False
True or False?
Objects will reach the same temperature: Thermal Equilibrium.
True
