Test for Non-Living Things
To test non-living things, we can use various methods to determine their properties and characteristics. Here are some common tests:

1. Physical Properties Test
- This test involves observing and measuring physical characteristics such as size, shape, color, texture, and weight of the non-living object.
- For example, we can measure the length of a ruler or observe the color of a rock.

2. Conductivity Test
- This test determines if an object can conduct electricity. Conductivity testing is commonly used for metals and other materials that conduct electricity.
- For example, we can use a simple circuit with a battery and bulb to test if a material is a conductor.

3. Solubility Test
- This test checks if a substance can dissolve in a liquid. It helps us understand the chemical properties of non-living things.
- For example, we can test if salt dissolves in water by mixing them together.

4. Magnetic Test
- This test determines if an object is attracted to a magnet. Metals such as iron, nickel, and cobalt are known to be magnetic.
- For example, we can use a magnet to see if a paperclip is magnetic.

5. Density Test
- This test measures the mass of an object relative to its volume. It helps us understand the compactness of a material.
- For example, we can compare the density of a wooden block and a metal block by measuring their mass and volume.
These tests can help us classify and understand non-living things based on their properties and characteristics. By conducting these tests, we can learn more about the world around us and how different materials behave.
