Class 9 Chemistry Project Ideas For Summer Vacation 2024-25 

Note: It is always advised to do these experiments in the presence of an experienced professional.

1. Acid-Base Indicator Project 

Materials Required 

Red cabbage, Water, Strainer, Various household acids (e.g., vinegar) and bases (e.g., baking soda solution). 

Steps Required 

• Boil red cabbage leaves in water to extract the pigment. Strain out the leaves to obtain the indicator solution. 
• Put the solution in different containers. Add a small amount of each household acid and base to different containers. 
• Note the colour changes in the solution if it comes in contact with acids and bases. 
• Compare the colour changes and then note the colour changes. 
• Based on the colour changes, identify the substances tested as acids and bases. 
• Red cabbage indicator can be used as a natural pH indicator for household acids and bases.

2. Making Homemade Snow Project 

Materials Required 

Sodium polyacrylate (often found in disposable diapers or gardening stores), White vinegar, Water, Bowl, Spoon

Steps Required 

• Measure out a desired amount of sodium polyacrylate crystals into the bowl.
• Add a little water to it. You can also use a spoon to mix gently. 
• Now, observe the crystals. You will see the crystals will begin to absorb the water and expand significantly. 
• Continue adding small amounts of water until the mixture reaches the snow-like consistency. 
• If the mixture is too sticky, you can add vinegar to balance it out.
• For a more realistic feel, you can store the mixture in a refrigerator for some time. 

3. Pressure Bottle Rocket 

Materials Required 

2-litre plastic bottle (empty and clean), Cardboard or craft paper, Scissors, Duct tape, Straw, Bicycle pump (or pump with appropriate nozzle), Water (optional)

Steps Required

• Cut three triangular fins from a cardboard or any other paper that you have. 
• Tape the fins to the bottom of the bottle using duct tape. 
• Cut the circle from the cardboard and then roll it into a cone. Tape the narrower end of the cone to create a pointed nose cone. 
• Insert the straw with the help of the cork and push the cork tightly into the bottle opening. Add some water to the bottle.
• Now, attach the bicycle pump to the end of the straw and have an adult help you to launch the rocket. 
• Now, gently pump the air into the bottle and watch your rocket take flight. 

4. Growing Salt Crystals At Home

Materials Required 

Glass jar (clean and dry), Hot water, Table salt, String or thread, Pencil or skewer, Spoon (optional), Food colouring (optional)

Steps required 

• Boil enough water and then carefully pour it into a clean glass jar. 
• Start adding table salt to the hot water and keep stirring it until it reaches saturation. 
• Let the solution cool down. Till the time, you can create a seed crystal for faster growth. 
• Dip a clean string into the solution and let it hang for a minute to allow a small crystal to form. 
• Carefully, place the pencil or skewer across the top of the jar so the string hangs freely in the solution. 
• Now, it’s time for crystallisation. Place the jar in a cool place and cover the jar with a paper towel to prevent dust. 
• Wait for some time to let the crystals be formed.

5. Making Crystal Eggshells

Materials Required

Eggs (raw), White vinegar, Bowl or container, Baking soda (optional), Epsom salt (magnesium sulfate), Hot water, Spoon, Paintbrush (optional), Egg carton (optional), Food colouring (optional), Paper towels

Steps Required 

• Carefully, crack the eggs open and separate the yolk and whites for another use. Wash the eggshells gently with warm water. 
• Fill a bowl to fill the eggshells with vinegar. Let them soak for around 24-48 hours. 
• Carefully, remove the eggshells from the vinegar and rinse them thoroughly with clean water. 
• In a separate jar, heat the water and dissolve Epsom salt into it. Keep adding salt until it becomes saturated. 
• Now, carefully the hot solution into a shallow tray to hold the eggshells. Place the dish with eggshells in a cool place. 
• Cover the dish with a paper towel to allow some air circulation. 
• Wait for some time until the crystal eggshells are ready. 

Class 9 students can easily take a look at these chemistry project ideas that can help them with a better understanding of the scientific concepts.
