Science kits are readily available at most retailers that sell toys and include basic science items such as microscopes, tweezers, slides, test tubes, and instructions about simple experiments. These kits can be used to study fingerprints, leaves, bugs or random household items. Science kits are now being made that are detective kits, cooking kits, sea monkey kits and other variations.
Model rockets are a fun way to demonstrate the principles of flight, physics, and aerodynamics, as well as basic chemical reactions. These rockets can be purchased at any major toy store. Students can also make their own rockets by using basic household chemicals such as vinegar and baking soda, mixed in a plastic 20-oz water bottle. Both store bought and homemade rockets require adult supervision.
Bubbles are some of the most inexpensive and readily available toys that contain hidden scientific lessons. A bottle of bubbles can be used to teach about translucency, air and weight. Bubbles come with different shaped wands, in different colors, and can also be made at home. Students can build wands from everyday objects such as straws or funnels.
Erector sets are building toys that children can use over and over to learn the different principles of science. These sets can be motorized, teaching children about aerodynamics, mechanics and construction. Erector sets are great for teaching spacial thinking.
Modeling clay is a quick, inexpensive way to teach children about volume, pliability, and chemical reactions. Stretch the clay to demonstrate pliability. Have the children make clay animals and bake them to harden the clay to demonstrate a basic chemical reaction caused by heat.
