1 Poster Presentation, Gym
L B Haynes Science Spectacular 2009 Grades 3&4 Kickoff- February 27th , 11:30 A.M April 17th Poster Presentation, Gym Welcome to our first Science Spectacular. This is a voluntary event open to students in third and fourth grades. The goal of the Science Spectacular is to get students excited about science, expose them to scientific methods and encourage curiosity and observation. Each student or group of students interested in participating will choose a science project from the approved list provided with this handout or they may choose from other sources (books, websites, etc.). If they choose from another source, please submit a proposal for approval before beginning. The students will then proceed with their project while using the journal provided to guide them in the scientific method. The projects will all end with a poster presentation or model to be displayed for the students during school hours. This is not a competition. There will be no grading. It is simply to encourage interest in scientific exploration and observation. 1

2 2 3 Parents- What is expected of you? What is Scientific Method?
Find a problem or question you would like to answer- How does... Research the problem or question and find out everything you can. Make a Hypothesis - a hypothesis is a prediction. What do you think with happen based on everything you know? Conduct the experiment and collect data (numbers, measurements, photographs...) Organize your data into a format that makes it easy to see the results (pictures, graphs or tables) Form a conclusion. Check your recorded hypothesis (prediction). Were you right? Write about what you learned and what it means. Set up a poster which shows all of these items to share with your classmates and teachers. What is Scientific Method? 3 Parents- What is expected of you? Minimal oversight and guidance over the course of the project which will run from February 27th until poster presentations on April 17th (Poster should be brought into school on April 15th). Safety- Please be sure that your child outlines his/her plans to you and that you are aware of and approve of all of the steps and equipments involved. Your child’s safety is paramount. Some level of guidance in the construction of a poster to document the project at the conclusion of the project may be necessary. If you have any questions or need any support along the way, there is a contact list at the end of this booklet. Please call or with any questions. We are here to help! 2

3 5 4 Getting started… In comparison, a “not testable question” is:
General Vague Confusing Unrealistic Anything that would be unsafe to test Example: Not-testable question- How is one brand of battery different from another brand? Testable question- Which lasts longer: a brand-name battery or a store-brand battery? Choose a project from the approved list provided and choose a “testable question” that you would like to answer. Please record your project choice and question on the front sheet of your journal packet, remove that sheet and submit it to your teacher by Friday, March 6th. Now record your question on the next page of your journal. You may also choose a topic from another source, but 5 Getting started… How do I pick a science project? Well, what are you interested in? Use some of these ideas to help you choose a subject. Do you have a hobby? What do you wonder about? Is there anything you’ve seen or heard about that you have a question about? What do you think would be interesting to investigate? Now you need to come up with a “testable question” to answer. What is a “testable question”? A testable question should be: Specific Realistic Safe Harmless to you, other people, animals etc. 4

4 before you proceed, you need to submit a project proposal (see the front sheet of your journal packet) for approval. Please do not start on your project unless it is from the approved list until you have approval. Project types Model Experiment Survey NOTE: Models must be static displays (no active volcanoes, but a cut-out display explaining how a volcano works would be fine) Research your subject Talk to friends and family Read- books, internet (with parent’s permission) Interview someone with experience with your subject (experts) Make a hypothesis (prediction)- what do you think is going to happen? Record this in your journal. 6 Make an educated guess based on your research. A hypothesis is what you think will be the result of the experiment before you get started and why you think that. It could be right or wrong- that doesn’t matter as long as you think it through. Remember to record your hypothesis before you do your experiment. Procedure- This is where you plan out how to do your experiment in a way that will allow you to collect data in the process. What materials will you need? What are the steps you plan to take to perform the experiment? As you perform your experiment, record the data and, if appropriate, take pictures of the process. Many experiments need to be repeated 3 to 5 times to make sure you have the correct answer. 7

5 Title 8 9 Question Or Problem Hypothesis Materials: Procedure:
Which…. How…. I think that… Title Materials: Procedure: (Test the Hypothesis) Results Graphs, drawings, photos, charts- whatever form you choose to display your results. Conclusion If at any point you need any pointers or help, please contact one of us : Conclusions Did you find an answer for your question? Did what you predict occur? What happened? Remember, experiments are not always predictable. Your conclusion may be different from your prediction (hypothesis). That is OK. Your conclusion may also be that your experiment did not answer your original question. Can you still learn something from your data? Poster Your poster will not only show your results, but should contain all of the steps you went through to complete your experiment. You can use photos, bar graphs, measurements or numbers to show your data. Posters are due on April 15th and will be displayed for the school on April 17th. See example on facing page. 8 9
