The Egg in a Bottle science fair project is an opportunity for students to demonstrate their understanding of the forces of pressure. A board behind the project materials explains the concept to those not able to see the live demonstration and hear the explanation. Project backdrops contain at least a diagram of the experiment and an explanation of the result. Some science fairs issue specific rules on what should be included on the project board.
Read the rules of the science fair that pertain to the project board closely. Many science fairs request a specific number of graphs, charts and diagrams to quickly explain the project results. Failure to meet the standard requirements may cause an automatic point deduction or disqualification.
Draw a diagram showing each step of the Egg in a Bottle demonstration on card stock. Use arrows to show the movement of the egg. Add colour and details to make the diagram stand out.
Create the required charts and graphs on card stock paper. Show any variations in the result and the specifics of the data collected. Label graphs and charts thoroughly so they can be easily deciphered by the viewer.
Arrange the card stock diagram, charts and graphs on a tri-fold foam display board. Place the diagram of the egg going into the bottle in the centre panel to be the most prominent. Some display boards have a faint grid pattern for more uniform alignment and spacing.
Write the title of the project in bold at the top of the display backdrop. Mount the card stock onto the display board with double-sided tape. Mounting the images can be done at the science fair during the allotted set up time.
Card stock is rigid enough to be mounted so it is partially hanging off the side of the display board. This can give the backdrop an uncommon shape and eye-catching appearance. Measure the board with the card stock mounted in this way to ensure compliance with size rules. A tri-fold display board can be made from a standard piece of foam-core board, if you have difficulty acquiring one (see Resources). Divide the length of the board into thirds. Make two razor blade cuts along the division of each third without going all the way through the foam-core board. Flex the board at the incision lines to form the tri-fold.
