CONCEPT MAPA Quick Way to Revise Science

Concepts

What it is…• a diagram showing the relationships

among concepts • Concepts are connected with labelled

arrows, in a downward-branching hierarchical structure

• relationship between concepts is articulated in linking phrases, e.g., "gives rise to", "results in", "is required by," or "contributes to"

• Is concise and easy to remember

Concept Maps vs Mind Maps

• Concept maps– based on

connections between concepts

– is a downward-branching hierarchical structure

• Mindmaps– a diagram used to

represent words, ideas, tasks or other items linked to and arranged radially around a central key word or idea

– based on radial hierarchies and tree structures

Steps to constructing a concept map

1. Identify the main concept2. List all the concepts under the main

concept3. Begin with main concept at the top4. Use arrows to link to the next

concept(s)5. Write the linking words next to the

arrows to show the relationships

Let’s draw…

• Topic / Main concept : Living Things• What are some of the concepts

learnt for this topic?

Living Things

• 6 groups – animals, plants, fungi, protists, true bacteria and ancient bacteria

• Need air, water and food• Grow• Die• Respond to changes• Reproduce

Let’s draw a concept map…

• The previous concept map is incomplete.

• What is/are missing from the concept map?– Arrows & linking words/phrases

• In groups of four, complete the concept map by drawing the arrows and writing the linking words/phrases.

• Did you notice the highlighted concept ‘Flowering Plants’?

• We can further extend the previous concept map from the concept of ‘Flowering plants

• Before we can extend the concept map further, we have to identify some key concepts related to the concept ‘Flowering plants’

• Let’s identify the key concepts related to ‘Flowering plants’

Concepts For Flowering Plants

• They are:FlowersReproductive

• Now that we have identified the key concepts for the sub-topic ‘Flowering Plants, we can extend the previous concept map

• In groups of four, construct a concept map for the sub-topic ‘Flowering plants’, using the identified concepts

• To help you get started, let’s take a look at an except of the extended concept map for the sub-topic ‘Flowering plants’

Conclusion

• Concepts maps are based on the relationships between concepts but mind maps are just diagrams to represent words, ideas etc.

• In conclusion, concept map is a more effective tool for revising Science concepts
