First grade science project displays should have a short title in a large enough font that it can be read from two to three feet away. Title letters can be made out of construction paper, stencils or sticky letter labels purchased from an office supply or craft store. Too many details will distract so keep it simple and use black for ordinary text. Every school has varying requirements for display size, and three-sided display boards can be covered in colored paper or cloth. If you decide to use a colored display, stick to neutral shades so the background doesn't overwhelm the content. Rulers should be used to maintain straight lines; practice letter placement before adding them to the board permanently.
Explore biodiversity by collecting leaves. Parents or guardians can help children carefully collect leaves from the backyard, a park or other public area. Find leaves from different trees and bushes and build your science project display around your collection. Use natural colors and include comparisons of shape, color and size. Pressing and drying the leaves will make them easier to preserve and label in an herbarium, which can also be displayed.
Young students can be introduced to aerodynamics by building simple paper airplanes like the "Belly Button Glider." Displays can be decorated with sky blues, clouds, brief explanations of lift, comparisons of distance achieved with each model and the actual paper airplanes constructed for observation.
For students who live near a shore, a parent or guardian can take her to the beach to collect sea shells for a science project. The child can record where each shell was found and try to identify its type. Displays can be decorated in sandy colors and content such as collection location or concentration and the differences between the species of shells found can be laid out. Children can also write each location directly on the shell and display them in a small case.
