1 2013 LES SCIENCE AND TECHNOLOGY EXPO INFORMATION PACKET (This packet is intended as a resource and a set of guidelines for students and parents). PURPOSE: WHO: WHEN: WHAT: IDEAS: To have fun and develop our children s skills in critical thinking, gathering/analyzing data and communicating. All LES students. Group projects welcome. Wednesday, Feb. 20, 2013, from 6:30 8:00pm in the Gym. A non-competitive display of science and technology projects, experiments and demonstrations. Students will discuss their projects with Expo attendees. Students should plan to stay by their projects for the first 45 minutes of the Expo. The attached list is non-limiting and intended to get students thinking. We welcome novel and original projects. The most important pre-requisite for the project is that it must be interesting to the student. There is no access to running water in the gym. Hazardous materials are not permitted on school property. REMINDER: Each student will bring in their project to school on the day of the Expo and will set them up in the gym that afternoon after 2:00pm. They may present their project to their class in the morning.

3 Science Project Guidelines Choose a problem to solve. Craft your problem as a specific question. Research your problem. Form a hypothesis. Plan your project. Set up a time schedule. Make a list of all the materials you will need. Collect all of your materials. Conduct your experiments, several times. Record the data. Organize the data in or more orderly form. Draw conclusions from the data. Prepare your report, graphs, drawings, and diagrams. Construct your science fair data display. Milken Publishing Company, Science Fair.

10 LES SCIENCE AND TECHNOLOGY EXPO SAFETY GUIDELINES As you are planning your science project, think about how you will present it at the Science and Technology Expo. Your exhibit should show what you did, how you did it, and any results. Drawings, photographs, charts, graphs, and models are among the things you can use. Here are some safety guidelines to help you plan your exhibit: 1. Electricity will not be available for projects. Batteries may be used, but they are to be provided by the exhibitor(s). 2. Running water will not be available. 3. Avoid using valuable or treasured equipment since it could be misplaced or disturbed. 4. If the project involves liquids, try to seal everything carefully so there won t be any spillage. Please use a drip pan and have paper towels available to wipe up any spills that might occur. 5. Please keep safety in mind!! NO OPEN FLAMES NO POSION OR DANGEROUS CHEMICALS NO LIVE ANIMALS (INCLUDING INSECTS) NO BACERIAL, VIRAL, OR FUNGAL CULTURES GROWN FROM HUMAN OR ANIMAL SUBSTANCES
