This simple project can help demonstrate the way living things grow. Give each child a few dried beans or corn kernels and a plastic baggie; write each child's name on the baggie beforehand with a piece of masking tape and a permanent marker. Fold a moistened paper towel and place it in the bottom of each bag, and then place the seeds on the moist paper towel. Seal the baggies and place them in a sunny spot, or tape them directly to the classroom window. Have the students observe the sprouts that grow from the seed, and in the meantime discuss what kinds of things kids need to grow healthy and strong.
The five senses provide a base for a variety of simple science projects for kindergartners. For instance, have a taste test using "mystery" items such as popcorn, fruit or other bite-sized bits; blindfold the children and have them place different items on the tip of their tongues to try and identify the food. Students can also use other senses like smell, hearing and touch to figure out the identities of the items.
For this science project, take the class outdoors for a refreshing nature hike. The project will entail collecting small items found in the environment around your school, including flowers, leaves and rocks. Have the students make observations about what they see and find, like the different textures and colors, as well as any patterns they see. Have them make rubbings of the items they find by placing them underneath a plain sheet of paper, and then rubbing with a pencil. Allow each child to present something he is proud to have discovered.
This is a silly and simple project that will help demonstrate the concept of static electricity. Give each child an inflated balloon and tell the students to rub it against their clothing rapidly. The balloon should become charged and stick to the clothing. Similarly, take the balloon and rub it against a child's head for a literally hair-raising result. Ask the children to investigate and find out what other objects the balloon will stick to or pick up in the classroom.
