1. Solar Oven Experiment
With rising temperatures and deteriorating air quality, it is essential to encourage students to opt for renewable sources of energy. In this attempt to impart knowledge about alternate sources of energy such as solar power, teachers can suggest students create solar ovens.
To make a solar oven, you can use a cardboard box and line it with reflective material like aluminum foil. Thereafter, create a reflective lid and cover it with a transparent sheet. Once you reach this step, place your cooking vessel inside to harness sunlight for an eco-friendly cooking experience.

2. Water Filter Project
In addition, Class 7 Science teachers can assign water filter projects to their students to enable them to realize the importance of water conservation. Also, with this project, students will know about the increasing scarcity of water, owing to global warming and water pollution.
You need sand, gravel, and activated charcoal to create a simple water filter. After gathering the materials, layer them in a plastic bottle. Now, pour dirty water through the layers and observe as impurities are filtered out. Thereafter, you can explain the filtration process in your presentation by showcasing a cost-effective solution for clean water.

3. Electricity Generation from Fruits Experiment
When the world is dealing with a scarcity of electricity and witnessing the rapid depletion of fossil fuels, it has become essential to seek alternate sources of energy. If you are a school teacher, then it is your responsibility to teach students about the grave crisis and motivate them to use non-exhaustive sources of energy. In this attempt, you can ask students to generate electricity using fruits as a source.
For this, students can connect fruits such as lemons or potatoes to form a basic electrochemical cell. Now, measure the voltage produced as the fruits’ acids facilitate electron flow, showcasing the potential for harnessing small-scale, eco-friendly power sources.

4. Simple Circuit Experiment
In addition, as Class 7 students you can explore NCERT Class 7 Science Chapter 10 Electric Current and its Effect through simple circuit experiments. To create a simple circuit, you can connect batteries, wires, and light bulbs to create circuits. Thereafter, you need to investigate how various components impact the flow of electricity.
With this experiment, you must understand the basics of electricity by observing the illumination of light bulbs when circuits are complete. This hands-on approach helps grasp concepts like conductivity and resistance. Thus, you learn about the components of electrical circuits engagingly and practically.

5. Plant Growth in Different Soils Experiment
Furthermore, while covering NCERT Class 7 Science Chapter 1 Nutrition in Plants teachers can help students learn about different soil types through an experiment. Class 7 teachers can conduct experiments on growing plants in different types of soil to investigate the impact of diverse soil types on plant growth. This can be done by planting identical seeds in various soil compositions.
Thereafter, monitor and measure the growth of the plants over a designated period. The findings will enable students to learn about how soil characteristics influence plant development. In addition, students will learn about agricultural practices and understand the relationship between plants and their surrounding environment.
