What are the steps to plan and organize a school exhibition for toys made from waste materials?
To organize a toy exhibition: 1. Choose a purpose (awareness, creativity) and theme like eco-friendly toys. 2. Select and decorate a suitable venue. 3. Display toys attractively with creators’ names and labels. 4. Send invitations to parents and community members. 5. Arrange volunteers for visitor aRead more

What are some additional activities you can do to explore simple machines and their uses?
To explore simple machines, create a chain reaction model combining levers, wheels, and pulleys. Repair a bicycle to understand how simple machines interact. Observe tools like scissors or bottle openers at home to identify their mechanisms. Research historical uses of simple machines, such as leverRead more
To explore simple machines, create a chain reaction model combining levers, wheels, and pulleys. Repair a bicycle to understand how simple machines interact. Observe tools like scissors or bottle openers at home to identify their mechanisms. Research historical uses of simple machines, such as levers in temple construction. These activities enhance problem-solving skills and demonstrate the relevance of simple machines in daily life and larger engineering projects.
See lessRusting of an article made up of iron is called (a) corrosion and it is a physical as well as chemical change. (b) dissolution and it is a physical change. (c) corrosion and it is a chemical change. (d) dissolution and it is a chemical change.
The correct answer is: (c) Corrosion and it is a chemical change. Rusting occurs when iron reacts with oxygen and moisture, forming iron oxide (rust). This process alters the chemical composition of iron, making it a chemical change rather than a physical one. https://www.tiwariacademy.com/ncert-solRead more
