Designing and testing a parachute, breeding bacteria and creating a butterfly habitat are examples of good scientific activities for kids. Other activities include making a battery and creating a rainbow.
By designing and testing a parachute, kids learn about gravity and air resistance. All that is necessary for the activity is a plastic bag, scissors, string and a small object to act as weight and represent a skydiver.
Growing bacteria teaches kids about germs and scientific processes, and the project shows kids how quickly bacteria grow in the right conditions. The necessary materials for the activity include a Petri dish of agar, cotton buds and some old newspaper.
Creating a butterfly habitat is relatively simple; this engaging activity introduces children to animal science. The necessary materials for an outdoor habitat include butterfly larvae, flowers, twigs and a small plastic dish. An indoor habitat requires netting and a flat tray.
Making a battery requires 1/3 cup of lemon juice, nine sheets of paper towel, five pennies and five zinc-coated washers. The project represents the discoveries of Alessandro Volta and teaches children about electricity.
Children can learn about the refraction of light by making their own rainbow, which just requires a glass of water, white paper and sunlight.
