Fun and Engaging DIY Activities to Explore "Is Matter around Us Pure?
Are you a high school teacher or a homeschooling parent looking for exciting ways to teach the concept of "Is Matter around Us Pure?" to your students or children? Look no further! In this blog post, we've curated four hands-on DIY activities that will make learning about solutions, colloids, suspensions, emulsions, and separation techniques a delightful experience.
Activity 1: Making Solutions, Colloidal Solutions, and Suspensions
- Chalk powder, Dettol, salt, small light source
- In this activity, students will make different types of mixtures using chalk powder (solution), Dettol (colloidal solution), and salt (suspension).
- They will then observe the scattering of light through these mixtures using a small light source.
- This will help them understand the differences between solutions, colloidal solutions, and suspensions.
Activity 2: Making a Colloid Emulsion
- Students will create a colloid emulsion by mixing water and oil.
- They will observe the formation of tiny droplets of one liquid dispersed in another.
- This activity will demonstrate how emulsions are formed and introduce the concept of colloids.
Activity 3: Creating a Centrifuge
Water, oil mixture, two test tubes, motor axle, battery (cell)
- In this activity, students will construct a simple centrifuge using a motor axle and a battery.
- They will fill two test tubes with a mixture of water and oil and attach them to the spinning motor axle.
- As the centrifuge spins, students will observe the separation of the liquids based on their densities.
- This activity will introduce the process of centrifugation as a method for separation.
Activity 4: Separation Based on Solubility - Chromatography
- filter paper
- two color marks of sketches
- Students will perform chromatography using water in a glass, a straw with filter paper, and two color marks of sketches on the filter paper.
- By dipping the straw into the water and allowing it to absorb, they will observe the separation of colors on the filter paper.
- This activity will illustrate how different components of a mixture can be separated based on their solubility in a solvent.
Science behind the Chromatography - Exhibits the separation of different pigments in a mixture based on their solubility and movement through a medium.
