Science Experiments for Class 6

Q: 4. How do I answer HOTS or 'what if' questions related to a science experiment?

These questions, often called HOTS (Higher Order Thinking Skills), test if you understood the core principle of the experiment. To answer them, first recall the main scientific rule. For example, if the experiment is about circuits and the question is, “What if a plastic scale is used instead of a wire?”, you should first remember that plastic is an insulator of electricity. Then, you can explain that the circuit would be incomplete and the bulb would not glow.

Improve Practical Knowledge with Easy Science Experiments for Class 6

Performing Science Experiments for Class 6 is an exciting opportunity for students. To be honest, it is a commonly held belief that every child has a natural inclination towards science, which is often hidden within them. Kids are naturally curious and tend to be interested in examining science activities and experiments. They may be more enthusiastic about participating in science experiments than reading or writing about them. For instance, if they observe a mysterious behaviour of water in straws or under heat, they want to understand why. Similarly, they would demand an explanation if light creates a rainbow on the wall.

The Science Experiments for Class 6 NCERT are designed to cater to students' natural inquisitiveness and provide them with the information they seek. These experiments are tailored to the CBSE curriculum and are ideal for students studying on this educational board. Moreover, these experiments require very little time and do not burn a hole in the pocket. They only require easily available household items, with a few exceptions that can be conveniently purchased from the local hardware store.

These Science Experiments for Class 6 with Explanations are designed to help students develop a scientific temperament and enhance their understanding of the subject. By engaging in these experiments, students can witness the principles of science in action and gain a deeper insight into the workings of the natural world. Furthermore, the experiments are structured to encourage students to think critically and apply the scientific method to solve problems. Let us have a look at some of these experiments, shall we?

Creating Wind Chimes

Have you ever been mesmerised by the beautiful sound of wind chimes swaying in the breeze? If so, you may have wondered about the science behind their melodious tinkling. Luckily, with just a few simple instructions and easily accessible materials, you can learn how to make your wind chimes that produce stunning music.

To make a wind chime, you will need weather-resistant materials such as thin redwood panelling, aluminium chimes made of shower curtain rods, oak or other durable material for heavier tubes, fishing line or nylon cord to hang everything from, and weather-resistant golf balls or round wood pieces for strikers.
Anodised aluminium tubing about 3/4 or 1 inch in diameter is best for sound, but half-inch or three-quarter-inch galvanized electrical conduit works well too.
To make the chimes, you must cut the tubing, measure and mark the spots, drill the holes, and smooth out any burrs.
You can determine the pitch of each chime by striking it with a piece of wood, golf ball or rubber hammer, and using a piano keyboard or computer interface to find the frequency.
Once you know the pitch, you can calculate the lengths needed to make a "tuned set of chimes."
Suspend each chime with a fishing line or nylon cord and add a wind-catcher to the end of the cord. Finally, suspend the platform with the line to hang level.

Making Slime

Who doesn’t love playing with ooey-gooey slime right? Well, you can make one for yourself at home. Here is one of the best Science Experiments for Class 6. For creating the slime you will need Borax powder, food colouring, water, a bowl of medium size, a spatula, measuring cups, a small cup, glue etc.

It is important to ensure that your hands are washed right before and after playing with slime. Do not eat the slime or let others eat it. Only set slime down on surfaces that won't absorb food colouring
To make the slime, mix around 1 teaspoon (5 ml) of Borax powder into 1 cup of water (250 ml) to create a Borax solution and set it aside.
Empty 100 ml of glue into a bowl and mix in about 100 ml or ½ a cup of water (~125 ml) to create a diluted glue mixture.
Add 1-2 drops of food colouring to the glue mixture, unless you want a colourless slime.
Slowly add the Borax solution to the glue mixture, observing the change in consistency.
Knead the slime with your hands. Slime tends to lose its stickiness the more one plays with it.
Store the slime in a zipper-lock bag and dispose of it when it starts to look unpleasant

FAQs on Science Experiments for Class 6

1. What types of questions are generally asked from science experiments in the Class 6 exam?

In the CBSE Class 6 Science exam for 2025-26, questions based on experiments test your practical understanding. You can expect a mix of formats, including:

Multiple Choice Questions (MCQs) on the materials required or the aim of an experiment.
Short answer questions asking for the conclusion, like in the test for starch.
Diagram-based questions where you need to label the setup of an electric circuit or parts of a flower.
Procedural questions asking you to list the steps for simple activities like filtration or sieving.

2. How should I structure my answer for an experiment-based question to score full marks?

To score well, it's best to answer in a structured way. For any experiment, like showing that light travels in a straight line, make sure to include these five key points:

Aim: What you are trying to prove.
Materials Required: A list of all the items used.
Procedure: A step-by-step description of how to conduct the experiment.
Observation: What you saw, heard, or measured during the experiment.
Conclusion: The final result that proves the aim.

This method ensures your answer is complete and easy for the examiner to evaluate.

3. Why is it so important to draw a neat, labelled diagram in questions about experiments?

A neat and correctly labelled diagram is crucial because it can often earn you full marks for that question. It visually communicates your understanding of the experimental setup. For topics like building an electric circuit or showing the parts of a flower, a good diagram clearly showing the cell, bulb, switch, and wires is more effective than a long paragraph and proves you understand the concept practically.

4. How do I answer HOTS or 'what if' questions related to a science experiment?

These questions, often called HOTS (Higher Order Thinking Skills), test if you understood the core principle of the experiment. To answer them, first recall the main scientific rule. For example, if the experiment is about circuits and the question is, “What if a plastic scale is used instead of a wire?”, you should first remember that plastic is an insulator of electricity. Then, you can explain that the circuit would be incomplete and the bulb would not glow.

5. Which experiments from the Class 6 syllabus are considered most important for exams?

While it is best to study all topics, some experiments are frequently tested in exams. For the Class 6 Science paper, you should focus on understanding:

Tests for the presence of starch, proteins, and fats in different food items.
Techniques for separation of substances, like filtration, evaporation, and sieving.
Constructing a simple electric circuit and identifying conductors and insulators.
Activities demonstrating the basic properties of magnets, such as attraction and repulsion.
Experiments showing that air has weight and occupies space.

6. Apart from the final result, what is the most important detail to include in an answer about an experiment?

The most critical detail to include, besides the final conclusion, is your observation. The observation is the evidence you collect during the experiment. For example, stating “the potato slice turned blue-black after adding iodine solution” is a key observation. Writing a conclusion without mentioning the observation that led to it can cause you to lose marks, as it doesn’t show you understand the experimental process.
