Some science experiments for third graders include testing capillary action, sound vibrations and static electricity. Students can demonstrate capillary action using paper towels, glasses and water, test the effect of sound vibrations on a cling film stretched across a bowl, and generate static electricity by rubbing balloons with woolen socks.
Third grade students can carry out some experiments independently, while others require adult supervision to prevent accidents or avoid creating a mess. Examples of experiments that require supervision include testing the explosive reaction between vinegar and baking soda and creating bubble art using powder paints and dishwashing detergent. Hands-on scientific activities succeed in holding the attention of children, encouraging them to apply their mental and manual skills constructively. Learning about apparatus and procedures sparks an interest in science and helps students build a direct connection with the subject.
Children can conduct experiments indoors, such as making their own cloud in a bottle, or they can go outdoors for activities such as estimating the age of trees. In addition, experiments can encompass the fields of biology, chemistry and physics and can deal with various aspects of the Earth, nature, plants and animals, or space. At home, the children can use easily available and safe materials.
