Check out the science project ideas for class 7 students below, which are designed to be easy and fun. These science project ideas for class 7 easy will make learning an enjoyable experience while fostering a deeper interest in scientific exploration.

 Check out the 10 Easy Topics for Science Projects for Class 7 Students below:- 

1. Action of Acids and Bases on Litmus Paper

Process:

1. Take two pieces of blue litmus paper and two pieces of red litmus paper.

2. Use a dropper to place one drop of lemon juice on a piece of blue litmus paper and one drop on a piece of red litmus paper.

3. Next, take another dropper and put one drop of baking soda solution on the other piece of blue litmus paper and on the remaining red litmus paper.

4. Carefully observe any colour change on the papers.

Result:

When an acid (lemon juice) touches blue litmus paper, it turns red, indicating that acids cause this colour change. On the other hand, bases (like baking soda solution) turn red litmus paper blue. These changes show the different effects of acids and bases on litmus paper, helping us easily identify substances as either acidic or basic.

2. Finding Different Speeds of a Car

Process:

1. Use a metre scale or measuring tape to mark a straight path of 1 to 3 metres on the floor.

2. Place the toy car at the starting point of the marked path.

3. Gently push the toy car and, at the same time, start the stopwatch to measure how long it takes for the car to reach the end of the path.

4. Record the time it takes for the car to cover the distance in your notebook.

5. Now push the car with a stronger force and repeat the process, recording the time each time the car covers the distance.

6. If you have a ramp, you can place the car at the top of the ramp and allow it to roll down, recording how quickly it reaches the end of the path.

Result:

By calculating the speed of the toy car using the formula Speed = Distance ÷ Time, you’ll notice that the car travels faster when pushed harder. The same happens when the car rolls down a ramp, as gravity adds extra force, increasing its speed. This experiment shows how different forces and conditions affect the movement of an object.

3. Observing a Chemical Reaction Between an Element and a Solution

Process:

1. Pour the copper sulfate solution into a beaker.

2. Carefully place an iron nail into the solution, ensuring it is fully submerged.

3. Leave the nail in the solution for a few hours.

4. After the time has passed, observe the iron nail and the solution to see any changes in colour or appearance.

Result:

After a few hours, a reddish-brown layer of copper will appear on the iron nail, while the solution will change colour from blue to green. This reaction occurs because iron displaces copper from copper sulfate, forming iron sulfate and depositing copper on the nail. This science project for class 7 demonstrates a chemical reaction between an element and a solution.

4. Investigating the Activity of Saliva on Starch

Process:

1. Prepare two test tubes, each containing starch solution.

2. Into one test tube, add a small sample of saliva.

3. Leave the second test tube unchanged to act as a control.

4. Wait for 10 minutes and then add a few drops of iodine solution to both test tubes.

5. Observe any changes in colour in both test tubes.

Result:

The test tube without saliva will turn blue-black when iodine is added, indicating that starch is present. The test tube with saliva will not turn blue-black because the enzyme in saliva (amylase) breaks down starch into simpler sugars, which do not react with iodine. This science project for class 7 experiment shows the digestive role of saliva in breaking down starch.

5. Investigating the Nature of Gas We Breathe Out

Process:

1. Fill a glass beaker halfway with lime water.

2. Using a straw, blow air gently into the lime water for about 1 to 2 minutes.

3. Observe the lime water to see if any changes occur.

Result:

After blowing into the lime water for a few minutes, it will turn cloudy or milky. This happens because carbon dioxide from the air you breathe out reacts with lime water (calcium hydroxide) to form calcium carbonate, which causes cloudiness. This science projects for class 7 working models experiment shows that the air we exhale contains carbon dioxide.

6. Constructing a Temporary Magnet Using Electricity

Process:

1. Take a long piece of copper wire and wrap it tightly around an iron nail, leaving enough wire free at both ends to connect to the battery.

2. Attach the ends of the copper wire to the positive and negative terminals of the battery, creating a circuit.

3. Now, hold the iron nail near some small objects like paper clips and see if they are attracted to the nail.

Result:

When the wire is connected to the battery, the iron nail will attract small metal objects like paper clips, showing that it has become a magnet. However, once the battery is disconnected, the magnetism disappears, proving that the iron nail becomes a magnet only while an electric current flows through the wire. This is called an electromagnet.

7. Action of Natural Indicators

Process:

1. Boil a few red cabbage leaves in water to extract the purple cabbage juice, which will act as a natural indicator.

2. Pour the cabbage juice into two separate beakers.

3. Add lemon juice (acid) to one beaker and baking soda solution (base) to the other.

4. Watch for any colour changes in the cabbage juice.

Result:

The cabbage juice will change colour when mixed with an acid or base. It turns pink in an acidic solution (like lemon juice) and green in a basic solution (like baking soda). This experiment shows that natural substances, like red cabbage juice, can act as indicators to identify whether a solution is acidic or basic.

8. Neutralisation Reaction Using Acid and Base

Process:

1. Pour some vinegar into a small beaker or cup.

2. Gradually add a spoonful of baking soda into the vinegar.

3. Observe the fizzing and bubbling that occurs during the reaction.

Result:

When you add baking soda to vinegar, a fizzing reaction occurs. This happens because the acid (vinegar) reacts with the base (baking soda), producing carbon dioxide gas, water, and salt. This reaction is called neutralisation, and it is useful in many everyday processes like cleaning and cooking.

9. Chemical Change in Burning of Magnesium Ribbon

Process:

1. Wear safety goggles to protect your eyes.

2. Use tongs to hold a small piece of magnesium ribbon.

3. Light a Bunsen burner or candle and bring the magnesium ribbon close to the flame until it starts to burn.

4. Observe the reaction as the magnesium burns.

Result:

As the magnesium ribbon burns, it produces a bright white light and leaves behind a white ash, which is magnesium oxide. This is a chemical change because magnesium reacts with oxygen in the air, forming a new substance. This reaction is an example of combustion, and it also demonstrates the formation of an oxide.

10. Finding Different Speeds of a Car

Process:

1. Measure and mark a straight path on the floor using a metre scale or measuring tape.

2. Place the toy car at the starting point of the marked path.

3. Push the toy car gently and start the stopwatch to time how long it takes for the car to cover the distance.

4. Write down the time in your notebook.

5. Repeat the process with different pushes to vary the speed of the car, and record the time each time.

6. If you have a ramp, let the toy car roll down it, and measure the time it takes to travel the marked path.

Result:

After calculating the speed for each trial, you will observe that the toy car moves faster when pushed with more force. The same is true when using a ramp, as gravity increases the car’s speed. This experiment shows that speed depends on the amount of force applied and the conditions under which the car moves.
