There are several interactive activities and experiments mentioned in the Science textbook for Class 7. These activities and experiments are designed to engage students and enhance their understanding of scientific concepts through hands-on experiences. Here are some of the interactive activities and experiments mentioned:


One of the activities mentioned in the Science textbook is growing plants. Students are encouraged to plant seeds and observe the growth process. They can study the different stages of plant growth, the importance of sunlight, water, and nutrients for plants, and the role of photosynthesis.


Another activity mentioned in the textbook is investigating forces. Students can perform experiments to understand the concepts of force, motion, and friction. They can measure the force required to move different objects on different surfaces and observe how friction affects the motion.


The textbook also includes an activity on building electrical circuits. Students can learn about different components of a circuit, such as batteries, wires, bulbs, and switches. By constructing circuits and observing the flow of electricity, they can understand the concepts of open and closed circuits, current, and voltage.


An interactive activity mentioned in the textbook involves exploring the properties of light. Students can investigate the behavior of light by conducting experiments on reflection, refraction, and dispersion. They can use mirrors, lenses, and prisms to observe how light behaves in different situations.


The textbook also includes an experiment on investigating acids and bases. Students can test the pH of different substances using litmus paper or pH indicators. They can learn about the properties of acids and bases, their reactions, and the importance of pH in everyday life.

Overall, these interactive activities and experiments mentioned in the Science textbook provide students with practical experiences to reinforce their understanding of scientific concepts. By actively participating in these activities, students can develop critical thinking skills, enhance their problem-solving abilities, and foster a deeper appreciation for the wonders of science.
