This is a Grade 7 Science learning resource for learners that focuses on the properties of metals and non-metals, using the history of Philippine coins as a practical example. It includes activities to explore electrical conductivity, magnetism, and the acidity of oxides. It also incorporates practical recycling projects to promote the value of metals.
Objective
1. Identify the metals used in different series of Philippine coins.
2. Analyze why metals are used in coins based on their properties.
3. Recognize the importance of saving coins.
4. Observe and describe the properties of metals in different Philippine coins.
5. Differentiate conductive and non-conductive metals.
6. Distinguish between metals and nonmetals based on the acidity of their oxides.
7. Design and create products using scrap metals.
8. Construct and use an improvised electrical conductivity tester.
