DIY Activity Ideas: Exploring the Separation of Substances
Introduction:
The process of separating different substances from a mixture is an important concept in chemistry. In these DIY activities, we will engage in hands-on experiments to understand and demonstrate various methods of separating substances.
Activity 1: Hand Picking
Materials Required:
- Mixture of thermocol balls gravel
- sand
- sugar
- corn flour
- paper tray
Procedure:
Carefully pick out the thermocol balls from the mixture using your hand. This activity demonstrates the simple method of hand picking to separate substances based on their physical properties.
Activity 2: Sieving and Winnowing
Materials Required:
- Eva foam sheets
- screw
- fan
- battery (cell)
- double-sided tape
- paper tray
- metal strip
- motor axle
- wires
- pins
- mesh
- transparent sheet
- two wood sticks
Procedure:
Construct a model of a fan stand using Eva foam sheets as the base pad and frame.
Attach the fan, battery, and motor axle to create a working circuit. Place the transparent sheet in front of the fan and pour the mixture on top of the model. Observe the separation of substances through sieving and winnowing. The lighter particles will be blown away while the heavier ones will remain.
Activity 3: Sedimentation and Decantation
Materials Required:
- Two cups
- water
- mixture from Activity 2
Procedure:
Pour the mixture into one cup and add water. Stir the mixture and allow it to settle. After some time, carefully pour the water into another cup without disturbing the sediment at the bottom. Observe the separation of substances through sedimentation and decantation. The heavier particles settle at the bottom, allowing the clear water to be decanted.
Activity 4: Filtration
Materials Required:
- Mixture from Activity 3
- filter paper
- cup
Procedure:
Pour the water mixture obtained from the previous activity into the cup containing a
filter paper. Observe how the filter paper separates the solid particles from the liquid. This activity demonstrates the process of filtration, where substances are separated based on their particle size.
