Making a cutaway-model of the Earth’s layers is a fine science project for lower elementary school students who are not usually restricted to experiment-centered projects. Making a model of the Earth’s layers is an educational and visually impressive project. There are a variety of materials, techniques and approaches that will work, but most feature differently colored materials to represent the various layers of the planet.Know More
The Earth has four primary layers. All of the various organisms that live on Earth do so on the crust, the thinnest of the four layers. Immediately inside the crust, the 1,800-mile-thick layer of semi-solid rock called the mantle separates the crust from the planet’s core. The Earth’s core is divided into two parts, called the outer core and the inner core. The outer core is molten rock, while the inner core is a solid, dense lump of iron.
These layers can be portrayed for a science project by using different materials to represent each of the four layers. For example, a red lump of clay may represent the inner core, while a layer or yellow clay around it can represent the outer core, followed by a blue layer for the mantle and a brown layer for the crust.Learn more about Layers of the Earth
Many websites created by science teachers and educational organizations provide ideas for science projects, including ScienceBuddies.org, ScienceBob.com and ScienceProjectsForKids.com. These projects cover all scientific areas, including physics, robotics, geology, biology and zoology. Each project comes with a list of materials and procedures so projects can be carried out at home.Full Answer >
One idea for a good third-grade science project is to test how smell affects taste by having 15 volunteers taste various pieces of fruit. For the first round, they'll be blindfolded, the second round they'll have their noses plugged and the third round they'll be blindfolded again.Full Answer >
According to ScienceFairAdventure, determining if color affects the rate at which a candle burns is an interesting science experiment conducted using candles. This science experiment determines which color of candle burns the fastest and which ones burn the slowest.Full Answer >
A couple of good ideas for a fourth-grade science fair project are to find out if crawling insects prefer to move toward a specific direction and to determine the rate at which colored and clear ice cubes melt. Students can also try discovering if magnetism travels through certain materials.Full Answer >
