Collaborative Learning for Educators by May Kyaw https://padlet.com/yumay08/7bpjpmocas8339qk A space for our class to share what they’re thankful for! en-us 2025-01-07 12:43:22 UTC 2025-01-22 15:57:29 UTC hello@padlet.com 1. Solutions and Light yumay08 https://padlet.com/yumay08/7bpjpmocas8339qk/wish/3297104316 Definition: Solutions are homogeneous mixtures where the solute is completely dissolved in the solvent (e.g., saltwater, sugar water).


Effect of Light: Solutions allow light to pass through without scattering.


Why? The particles are too small (molecular size) to interfere with the path of light.


Example: A glass of saltwater appears clear when light passes through.

Suspensions and Light yumay08 https://padlet.com/yumay08/7bpjpmocas8339qk/wish/3297105239 Definition: Suspensions are heterogeneous mixtures where the particles are large and tend to settle over time (e.g., sand in water, muddy water).


Effect of Light: Suspensions block or scatter light significantly, making them opaque or cloudy.


Why? The large particles are big enough to scatter light in different directions.


Example: Muddy water blocks most of the light.

Colloids and Light (Tyndall Effect) yumay08 https://padlet.com/yumay08/7bpjpmocas8339qk/wish/3297105756 Definition: Colloids are mixtures with medium-sized particles that are evenly dispersed but not dissolved (e.g., milk, fog).


Effect of Light: Colloids scatter light when a beam passes through, causing the Tyndall effect.


Why? The particles are small enough to stay suspended but large enough to scatter light.


Example: A beam of light is visible when shone through fog or milk.

  • Write in the center you can use the following topic.

    • Mixtures and Light interaction

    • Solutions, Suspensions, and Colloids


    1. Add three main branches, one for each type of mixture.

    • solutions

    • suspensions

    • colloids


    1. For each branch, add sub-branches with the following key facts.

    • Definition

    • Light interaction

    • Examples

    • Visual cue


    1. You can use

    • arrows or lines to connect the central topic to the main branches.

    • icons or images to make it visually appealing.

    • Highlight key terms like " Tyndall effect or Light pass through"


    1. Use colors to differentiate the three types.
