10 Easy To Make Science Projects For Class 7 Students
Science Experiments to do at Home
Looking for the coolest science projects for your grade seven child. Here are some very popular & interesting science projects you can refer to.
Class 7 is a crucial phase of the student’s life. It is the time when a student starts learning the alphabet of science. Parents need to put extra effort into the child’s activity and academic curriculum to develop critical thinking ability.
It often happens when your child asks you to assist him in projects for the school science fair, and you find blank what to suggest, so you end up finalizing the boring LEDs projects.
In this blog, we will suggest 10 easy-to-make kids-friendly science projects that will help them grow their domain of science knowledge and critical thinking.
10 Science Project Ideas For Class 7 Students
1. Bio-gas Plant
Bio-gas are produced by the decomposition of plants and animal waste. Although you can say, it is the process of taking energy from the garbage. It is a mixture of methane and carbon dioxide. Check out the process of creating a biogas project. For more details, check NCERT Solution for class 7 science.
Objects required- funnel, glass vessel, test tube, plants or pond sludge remains, pond water, lighter, thin wooden chip, laboratory goggles, and adult supervisor.
Process- Put the pond’s sludge or plant remains into the glass vessel. Place the funnel on the glass vessel and pour the pond water, so the funnel’s stem is above the water level. Put the inverted test tube on the funnel and fix it with the help of adhesive tape.
Leave the arrangement in a warm place for a couple of days. Afterward, put on the goggles, ignite the wooden chip, and hold it inside the test tube under the adult’s supervision. Now see the power of biogas.
2. Construct a Barometer
It is a scientific instrument that measures atmospheric pressure. To know more about this, read NCERT Solution for class 7 science. Follow the step-by-step guide to create your barometer.
Objects required- empty jar, balloon, a rubber band, a drinking straw, paper, scissors, pen, and some glue.
Process- Cut the balloon in half and throw away the piece with the neck on it. Take the remaining balloon, stretch it, and place it on the jar with the help of a rubber band. Place the straw at the top of the jar so that one-third part of the straw is hanging over the edge. Stick the straw to the balloon with the glue. The straw is your indicator. Stick a paper on the wall and place the bottle near the wall. Now watch the movement of the needle.
3. Create a Cloud
Clouds are always fascinating for kids. Create the clouds by using some household objects. Check how.
Objects required- Droppers, Blue Food Colour, A clear Jar, Shaving Cream, and a bucket of water.
Process- take a jar and fill it with water up to two-thirds. Add the shaving cream and wait until it settles down. Take a bowl and add a few drops of food coloring with a few water droplets. Put it to droppers, and the experiment start begins.
4. Study the Effects of Antibiotics on Micro-organism
It is a science experiment for class 9, but students of class 7 can also try this exciting experiment. For more details, you can refer to NCERT Solution for class 9.
Object Required- Potato, agar, dextrose, distilled water, four different types of antibiotics (such as penicillin, aureomycin, and Terramycin), syringe, oven sterilized Petri dish, flasks, beakers, pipettes, garden soil, glass marker pen, etc.
Process- Take the 200 gm of potato chips and boil them in the beaker for 15 minutes. Squeeze the potato pulp through muslin and place it into the flask. Take 20 to 30 gm of agar in a beaker and warm it up with 500ml water.
Mix the agar and potato with 20–25 gm of dextrose; one liter of PDA is prepared. Now autoclave the medium at 15-pound pressure for 15 minutes.
5. Identify the Boiling Point of Water
The temperature at which the water starts evaporating is called the boiling point of the water. Try this cool project to show the boiling point of water; for more, read Chapter 7 weather climate.
Object Required- round bottom flask, double bored cork, beaker, thermometer, stop-watch, spirit lamp, tripod stand with wire gauze, spring balance, a glass tube, polythene bag, laboratory stand, water, crushed ice, and thread.
Process- Take about 150 mL of water in the round bottom flask and close its mouth with two hole-stopper. Make a hole in the cork and fix the thermometer from one and the glass tube through the other. It is advised that the thermometer bulb should be in contact with the water in the flask.
Put the wire gauge on the tripod stand and keep the flask. Heat the water with the help of the spirit lamp or a gas burner. Note the thermometer’s reading with the use tch in the fixed interval of time. Identify the boiling point of the water.
6. Pin-Hole Camera
A pin-hole camera is primarily used to capture the sun’s movement for a long time, but here we will teach you how to make a pin-hole camera for students.
Object required- two pieces of white card, Aluminum foil, tape, and pin or paper clip.
Process- Make a square hole in the middle of the piece of white card. Place an aluminum foil over the blank space. With the help of a pin or paper clip, poke a hole in aluminum foil.
Now place the second piece of the white card on the ground and hold the aluminum paper in hand. Place the latter on the former(aluminum foil facing up) and make sure sun should be behind your back. View the projected image. The size of the image will vary depending upon your position.
7. Magnetic Compass
A compass is a device that is used for navigation and geographical directions. For more, read Science NCERT Solution for class 7.
Object required- A bar magnet, sewing needle, round piece of wax paper with a diameter of 3cm, and beaker full of salt water.
Process- Firstly, rub the needle from all sides( both end and middle) to magnetize the needle. Do it at least 50 times. Once the needle magnetizes, stitch the needle twice in the wax paper so that it gets stuck properly. Place the wax paper in the middle of the dish full of salt water. Let’s try to rotate the paper.
8. Capture the Sun
Object required- two lamps with moving lamp heads, two thermometers, two similar dishes, water, and black cloth.
Process- Firstly, put the dishes on the cloths and pour them with water. Place a lamp on the dish so that lights fall vertically on the water, and on the second dish, the light falls diagonally on the water. The distance between the lamps should be the same. After every five minutes, measure the temperature.
9. Bottle Rocket
Bottle rockets can be funny if it will tried with friends. By using some household stuff, you can make your science very interesting. Know-how.
Object required- Baking soda, colored pencils, vinegar, plastic bottle, wine cork, and tape.
Process- Tape the pencils around the plastic bottle as they act like rocket stands and stand on the ground properly — full the water with vinegar. Add some baking soda and immediately push the cork on the top of the bottle. Flip the plastic bottle and stay back away from your rocket launcher.

10. Electricity Generator
The electricity generator is one of the coolest science projects students choose in their metric or post metric. Framing this project enhances your child’s knowledge about how electricity generates.
Object required- DC motor, Pulley according to DC motor shaft size, LED, Led holder, Nut bolt and washer, Plywood, wooden stands.
Process- Initially, make a rotating wheel by gluing two circular discs on circular cardboard. Place the wooden bar on the base of the plywood. Join the DC motor shaft and moving disk with rotating rubber with the help of a nut and washer.
Now solder the DC motor with LED. Glue a bamboo or handle on the movable circular disc. When we rotate the circular disc, the LED starts glowing.
