Fourth grade students are very energetic and their span of attention or concentration is very small. Above that, they want to observe, infer, predict and classify anything taught on science. Learning by doing is a good concept and it registers in their young minds and they can never go wrong in their examinations. For this, a lot of schools conduct fourth grade science fair. Here, all the fourth grade science fair projects will be displayed.
The children explain their fourth grade science fair projects, while the others watch these projects and learn. Teaching them in a play way method is very effective. Here are few fourth grade science fair projects for this age group.
Salt increases the density of water. Add four to five tablespoons of salt in a glass of water stir it nicely and float an egg. Also add little more luke-warm fresh water and check, the egg will float in-between the salt and the water. Try using sugar or flour in the water the egg will sink.
Which water is good for plants can be made as a project by selecting a pot with some seeds; one pot can be watered with tap water, the other pot to be watered with only rain water. Check the growth for seven weeks; the rain water watered pot is better.
Will plants grow with a liquid other than water can be done in an effective project by selecting four pots, Water the first pot with water, second one with vinegar, third one with orange juice and fourth one with milk. The result is the one with water grows the maximum, the one with vinegar dies as it is an acid, the one with orange juice and milk also grows but nowhere near as much as the pure source.
A fourth grade science fair project to test which environment is best for plants. Take three pots, one with sand, one with soil, and one with gravel and put few seeds in each pot, wet them at regular intervals and make a graph, the seeds in the soil grew the maximum.
Classification of mammals -- Mammals are found every where. Polar bears in cold areas, camels in hot areas, moles live under the ground, bats live in caves and flies in the air and dolphins live in oceans. Fur and fat help them to protect themselves in cold regions and they sweat and pant to release their extra heat. A fourth grade science fair project can be made by cutting and pasting picture of mammals and their place of rest.
Sunflower house project: On the ground draw a square and plant sunflower seeds leaving enough space between two seeds all in the perimeter of the square, but don't forget to leave a little space in the front side for the door. Once the sunflower plants grow one inch, plant bean seeds around each sunflower plant. As they grow the beans will climb up the sunflower stalks and create a wonderful playhouse for the children. In this way they learn the characteristics of creepers, flower plants, trees, shrubs etc.
Excellent features of sunflowers are we can get oil, easy to grow and a good bird feeder, Make a sun and a flower and label its uses.
Life cycle of a butterfly - egg, caterpillar, cocoon and then a beautiful butterfly can be made live in your garden.
A Bird house can be made in wood, to encourage birds to come and live. Observe the birds and their habits.
Instincts can be taught in a project form by showing baby birds open their mouth for food, baby turtles know to go to the sea when their eggs hatch.
Children at this age group should be given simpler fourth grade science fair projects to keep them occupied. Once they are occupied and disciplined, teachers job become easier to make them learn and enjoy schooling.
