In case you want the children to explore the field of science on their own, then here are some simple science experiments that you can encourage them to perform. Various kits or sets, which provide the basic chemicals, apparatus, and other requirements are also available in the market. In case you don't want to buy these kits, there still exist a lot of experiments which can be carried out using simple things.
Development of a Seed
- Seed of any plant
- A gardening pot
- Fertile and moist gardening soil
- Take a small cup or pot of a convenient size and material.
- Add some moist fertile soil from the garden into the pot.
- Place some seeds into the pot and ask the children to water it regularly.
- Place the cup or the pot in sunlight so that the plant gets enough exposure to the sunlight.
The children will enjoy the offshoots and development of roots from the seed. It will also be a great learning experience for them. Teach them how water, soil, sunlight, and seeds are necessary for the creation and growth of a plant. You can extend the teaching session by introducing the children to the various parts of the plant - starting from the root, stem, leaves, and moving on to flowers and fruits.
- A hard plastic comb or inflated balloon
- Pieces of dry cereal
- Tie a piece of the cereal to one end of the thread.
- Find a place to attach the other end of the thread.
- Tape the thread to the edge of a desk using ordinary tape.
- Make sure that the comb is really clean, and free from dirt and oil.
- Rub the comb through long dry hair or a woolen blanket, so that it gets charged with static electricity, owing to the friction.
- Slowly bring the comb near the cereal. The cereal piece tied to the thread will move forward when touched with the comb.
- Hold it until the cereal moves away by itself.
- The cereal will tend to move away from the comb now.
It teaches the kids that friction with the hair, caused the electrons to be transferred from the hair to the comb. Since the comb was negatively charged with static electricity, the neutral cereal was attracted to it. When the cereal touched the comb, electrons were transferred to the cereal resulting in transfer of negative charge. Since both, comb and cereal were negatively charged after a while, it led to repulsion.
Most of these experiments can be performed at home, with a little supervision and help from the parents. Go ahead, and pick an experiment, which would not only be a fun experience for the child, but also a great way to learn basic scientific principles.
