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
There are a number of simple scientific experiments that kindergarteners can set up for a science fair, with one such example being a sunprint, which shows how the sun's energy can cause chemical changes by placing objects on photosensitive paper. The objects will block the sunlight, highlighting the contrast between the exposed paper and the protected parts through color change.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 >
The relationship between eye color and peripheral vision is a fairly simple and inexpensive idea for a science project. Using a homemade vision protractor, the peripheral vision of several subjects with different eye colors can be tested and charted to see if any correlation is noted.Full Answer >
Some good ideas for a ninth-grade science project are an experiment to determine the effectiveness of teeth whiteners, ways to keep bread fresh longer, and what makes a clothes dryer more efficient. They do not require a large amount of time, and all references used to research project topics should be cited.Full Answer >
