So your child is now a 4th Graders science fair project student, and you have no clue what to do for their science fair project.
At this age, students should understand units of measurement, plant and animal parts, the different states of matter, and the basics of how the sun, moon, and earth relate to each other.
Students continue to study physical, life, and earth sciences as they did in third grade, but at a higher level and in more detail. For instance, in third grade your child may have learned the anatomy of a plant as having roots, a stem, and leaves. At this level, he will continue to study the anatomy of plants, but at a biological level. Kids are taught the basic structure of plant and animal cells.
Students at grade level 4 will also learn how plants and animals survive in different habitats. Kids learn even more about what is needed for survival and how different species are interconnected in the circle of life. More vocabulary is taught, including male, female, and baby names for certain animals (i.e., a baby cow is a calf). Also, groupings of animals are named (i.e., a herd of cattle or a flock of geese). The life cycle of an animal will be taught to your 4th grader. Most notable is the caterpillar into a butterfly cycle. Because various ecosystems are studied at this level, a good science fair project may be testing certain life forms in altered environments.
Great science fair projects for this age will relate to the aforementioned
topics and will answer an interesting question. The hypothesis may be
the hardest part for some students, and the easiest part for others.
Suggest different general topics to your child, and then help narrow
down a question for the child to test. This becomes the scientific hypothesis
which will be tested in the project.
Popular projects include testing weather conditions or surveying weather
patterns in certain areas, demonstrating how tectonic plates move, inquiring
about a renewable resource, and testing electricity and magnetism.
Remember the age group of your fourth grader and be aware of his or
her maturity level. Some may think science is cooler than
others. To help your child become more interested in a topic, be sure
to involve him in daily activities that demonstrate how science is all
around us. For instance, have him water the house plants and compare
them to the trees outside that humans do not water. Why do the trees
survive outside without human assistance? Have your child observe the
stars through a telescope and ask him what he sees. Why does a certain
star look brighter than another? Is it really a star,
or is it a planet? Encourage your child to ask these questions and make
resources available, other than just his textbook.
