What do you Need to Know about Science Projects for Class 7 Working Models
In this section of the article, we are providing some Science Exhibition Working Models Ideas for Class 7 students. Performing these ideas and projects will enable them to understand the topic better.
Growing a Lettuce Project
Growing lettuce at home is a simple and rewarding process that can save you money and provide a fresh supply of this essential green leafy vegetable.
You'll need to select the right variety of lettuce for your location and climate to get started.
Next, you'll need to prepare your soil. Lettuce needs soil that drains well.. So, it is important to use organic matter to improve the fertility and texture of the soil.
Once your soil is prepared, it's time to plant your lettuce seeds. You can sow your seeds directly into the soil or start them indoors and transplant them later. When planting, space your seeds or seedlings according to the recommendations for your chosen variety.
After planting, keep your lettuce well-watered and weed-free. Lettuce prefers moist soil, so water it regularly, especially during dry spells.
In just a few weeks, your lettuce should be ready to harvest. You can pick the leaves individually or cut the entire plant at once.
Egg in a Bottle Project
We have an exciting and educational Working Model Of Science For Class 7 that demonstrates the concept of air pressure using an egg and a bottle.
You will need a medium-sized boiled egg, a bottle with a narrow neck (Erlenmeyer Flask, 1000 ml is recommended), and water.
Boil the egg by placing it in a pot and covering it with water. Bring the water to a boil, then turn the heat to medium. Cook for 10 minutes, remove from heat, and place them under cool water to chill them quickly. Crack and peel the egg.
Find a bottle with a neck that's small enough that the egg won't fall in. Put a little water around the rim to guard against the tearing of the egg.
There are two methods to get the egg into the bottle:
Method 1: Wad up a piece of paper, drop it in the bottle, and light it. Wait for it to burn out, and then immediately place the egg in the neck of the bottle. The egg will be sucked into the bottle due to the cooling of the air inside the bottle, which takes up less space and creates a low-pressure environment.
The external pressure outside the bottle will force the egg into the bottle to balance the pressure. To remove the egg from the bottle, turn the bottle upside down with the egg resting on the inside of the mouth. Now all you have to do is blow the mouth of the bottle, and when you stop, the egg automatically pops out.
Method 2: Hold the flask under hot water from the tap for 30-40 seconds, and then place the egg on top of the neck. Then you will have to make sure that the water is turned cold, and it will ensure that the egg is sucked inside. To remove the egg, tilt the bottle and allow hot water to run on the bottom flask.
