  1. Mixture Sorting: Prepare several containers filled with different mixtures such as sand and water, oil and vinegar, salt and sugar, etc. Provide students with a sorting chart and ask them to categorize each mixture as a homogeneous or heterogeneous mixture.

  2. Separation Techniques: Set up a station with various mixtures such as a mixture of iron filings and sand, saltwater solution, etc. Provide students with different separation techniques like filtration, evaporation, magnetism, etc. Ask them to use the appropriate technique to separate the components of each mixture.

  3. Concentration Experiment: Prepare a saltwater solution with different concentrations by dissolving varying amounts of salt in water. Provide students with a set of test tubes containing different concentrations of the solution. Ask them to observe and record the differences in appearance, taste, and density of each solution.

  4. Solubility Investigation: Provide students with a variety of substances such as sugar, salt, baking soda, etc. Ask them to predict and test the solubility of each substance in water. Students can record their observations and compare the results to determine which substances are soluble or insoluble.

  5. Making Solutions: Assign students to create their own solutions by dissolving different substances in water. Provide them with a range of substances like salt, sugar, food coloring, etc. Ask them to measure and record the amount of solute and solvent used for each solution. Students can then compare the properties and characteristics of their solutions.

  6. Density Column: Instruct students to create a density column using different liquids such as water, oil, honey, and alcohol. Provide them with graduated cylinders and various liquids. Ask them to carefully pour each liquid into the cylinder, one on top of the other, and observe the layers formed based on their densities.

  7. Chromatography: Provide students with filter paper strips and a set of colored markers. Ask them to draw a small dot of each marker on the filter paper strip. Then, dip the bottom of the strip into a cup of water, ensuring that the dots are above the water level. As the water travels up the strip, students can observe the separation of colors and discuss the concept of solubility.

  8. pH Testing: Provide students with a set of different solutions such as lemon juice, vinegar, baking soda solution, etc. Ask them to use pH test strips or indicators to determine the acidity or alkalinity of each solution. Students can compare and discuss the pH levels of different solutions and their effects on various substances.

  9. Crystal Growing: Provide students with a supersaturated solution of a substance like salt or sugar. Instruct them to carefully pour the solution into a container and leave it undisturbed for a few days. Students can observe the formation of crystals as the solvent evaporates and discuss the concept of saturation and solubility.

  10. Investigating Colloids: Prepare various colloidal mixtures such as milk, fog, gelatin, etc. Provide students with magnifying glasses and ask them to observe and describe the properties of each colloid. Students can discuss the particle size, stability, and appearance of colloidal mixtures compared to other types of mixtures.

1. Mixture Sorting: Sort different mixtures like sand and water, oil and vinegar, salt and sugar into groups based on whether they look the same throughout or have different parts.

2. Separation Techniques: Use different methods like filtering, heating, or using a magnet to separate things like sand and iron filings or salt from water.

3. Concentration Experiment: Make different salty water solutions and see how they look, taste, and feel to compare their strengths.

4. Solubility Investigation: Test if things like sugar, salt, or baking soda dissolve in water or not.

5. Making Solutions: Mix different substances with water to see if they dissolve and compare the properties of the solutions.

6. Density Column: Layer different liquids like water, oil, honey, and alcohol to see how they separate based on their heaviness.

7. Chromatography: Use water to separate the colors in markers on a paper strip.

8. pH Testing: Test the acidity or alkalinity of things like lemon juice, vinegar, or baking soda using special paper or liquid indicators.

9. Crystal Growing: Watch crystals form when a solution with a lot of salt or sugar dries out.

10. Investigating Colloids: Observe and describe things like milk, fog, or gelatin to see how they look and behave differently from other mixtures.
