Primary children are the best age group for a teacher to handle. They are small and curious to know and learn a lot. They are still simple, loving and obedient. If the teacher makes her class interesting by giving them third grade science fair projects, they understand very well and the concept becomes crystal clear in their minds.
A third grade science fair project for body parts - Make them place their palm and fingers on a piece of thick paper and trace the outline of all the fingers, the children can color the same, they can label the names of the different fingers and some children are innovative, they even decorate the ring finger by drawing a ring and paste shiny beads to depict a ring, some of them color the nails with nail polish.

Plants need air, sunlight, and water to grow. Take two plants and make them grow in different pots - one pot is placed outside whereas the other pot inside a cardboard box. Cut a small hole in any one side so that the sunlight can come through that hole. Observe after few days.
Does the amount of fertilizers given to a plant affect the growth? Take three plants, first one give only water, for the second one water plus little fertilizer and the third one water plus more of fertilizer, watch the plants, you will be surprised the one with only water is the best, so don't give too much of fertilizer to the young plant, once in a while one can give little bit.
