Fourth Grade Science
The elementary science project possibilities your child will encounter in the fourth grade will be more complex than what they have done in the past grade levels. With a broader science base or more knowledge to build on, you will find that while some elementary science projects are easy, the others may even surprise you.
In fourth grade life science, your child will further discuss plant and animal cells, and biomes. New to this level are the parts of flowers, which is what a plant uses to multiply. Also to be discussed are the life cycles of certain animals, as well as the r/K selection theory and the respiratory system of most animals, including that of humans. Life science will also cover endangered and extinct species, as well as causes and prevention of extinction. In the projects section, two elementary science projects were prepared for fourth grade life science, these are to chart the parts of different flowers, as well as to raise a tadpole and to observe its life cycle or development.
The earth science topics discussed in the fourth grade, are pretty easy extensions of what's already known to your child. The solar system and the sun and earth's parts are discussed in detail, as well as the reason behind why some countries have seasons and others don't. Children will also learn more about the weather, and the water cycle. The elementary science project for this section allow your child to create a “working” solar system that helps them understand both the sun and earth's parts, as well as the seasons. The project for weather, allows your children to create more home made weather instruments, and the water cycle is recreated in your very own home!
Finally, physical science introduces your child to simple machines, the concepts of friction, gravity, and physical or chemical changes of matter. The basics of how to separate mixtures is also discussed. The subject of energy is further explained through the elementary science project of creating an electrical circuit as well as conducting heat. A clear example of how electricity is generated will prepare your child for more discussions of energy and power.
