Step-by-step solution for: Mixtures and Separating Mixtures worksheet
To solve the problem of separating each mixture, we need to consider the physical properties of the materials involved (e.g., size, shape, density, magnetic properties) and use appropriate methods to separate them. Here are the solutions for each mixture:
---
- Properties: Paper is lightweight and non-magnetic, while clips are metallic and magnetic.
- Separation Method: Use a magnet to attract the metal clips, leaving the paper behind.
- Explanation: The magnetic property of the clips allows them to be easily separated from the paper using a magnet.
Answer: Use a magnet to separate the clips from the paper.
---
- Properties: Cereals come in different shapes, sizes, and densities.
- Separation Method: Use a sieve or a series of sieves with varying mesh sizes to separate the cereals based on their size.
- Explanation: Sieving allows smaller pieces to pass through the mesh, while larger pieces remain on top. This method works well for separating mixtures based on particle size.
Answer: Use a sieve to separate the cereals based on their size.
---
- Properties: Sand consists of fine particles, while pebbles are larger and coarser.
- Separation Method: Use a sieve or screen with a mesh size that allows sand to pass through but retains the pebbles.
- Explanation: The difference in particle size between sand and pebbles makes sieving an effective method for separation.
Answer: Use a sieve to separate the sand from the pebbles.

- Properties: Garbage contains various materials such as paper, plastic, glass, metal, food waste, etc., each with distinct properties.
- Separation Method: Sort the garbage manually or use a combination of methods:
- Manual sorting: Separate items by hand based on material type (e.g., paper, plastic, glass, metal).
- Magnetic separation: Use a magnet to remove metallic objects.
- Density separation: Use water to separate materials based on buoyancy (e.g., plastics float, metals sink).
- Shredding and screening: Shred the garbage and use screens to separate different-sized particles.
- Explanation: Since garbage is a complex mixture, multiple methods may be needed to effectively sort and separate the materials.
Answer: Manually sort the garbage into categories (paper, plastic, glass, metal, food waste), use a magnet to remove metallic objects, and use water or screens to further separate based on density or size.
