Scientific Principle Demonstration and Report

Fourth Grade

Tuesday, May 19 – Oral Classroom Presentation


For this project, you will choose a physical, geological, or chemical principle to demonstrate and explain. This can include how things fly, how dry ice works, gravity, rainbows, solar power, tornadoes, electricity, magnetism, volcanoes, tides, the birth of stars, the phases of the moon, the solar system, how rocks are formed, etc. Explain this principle to the best of your ability, including any famous scientists we associate with this topic.

Students should find a way to build (with help) a demonstration project that shows their principle in action that they set up and share at school. Create a small placard that simply explains it to display with the project—illustrations that instruct are encouraged.

In addition to creating a demonstration and writing a report on your topic, you must research some related topic to your principle. For example: If you choose flight, research airplanes, if you choose gravity, write about Galileo.

Your project must show effort, preparation, and research. Your report should be 3-4 pages long (not including the cover, title page, table of contents, illustrations, or bibliography) and should obviously be fully edited for spelling and grammar. As with any report, every word must always be either your own (paraphrased from your research) or a quotation. Your report must be presented extremely neatly and typed.

While some class time will be available for working on your projects, most of this will be homework. As such, you will continue to have a lighter than usual homework load in language arts. Many of you will use your time well and finish much of this report in the next few weeks. This is a great idea and will give you time to seek out special touches for your final draft. Being done early will also have the wonderful effect of giving you well-earned free time.


All reports must have the following:



The cover should have the title of the report, your name, and the date. It should be illustrated in some way that reflects the subject of the report.

Title page

The title page should have the title of your report, your name, the date, and your school name.

Table of Contents

This is a list of every section in the report and the page on which it can be found.


Give an overview/summary of your research. Invite your reader to enjoy your report. Talk about where you found your information and who helped you complete the report.


Your report must include at least two relevant hand drawn illustrations that help readers understand your topic. This does not include the cover.


Since the conclusion of an expository report should often engage your reader directly and focus on the future, tell the reader why they should care about the subject of your report (not simply, “You like your teeth, don’t you?”) invite them to learn more about the subject and give them advice how to do it. This is the “So What?” section.


You must keep a list of all of your source materials. List the Author, Publisher, Title, and Date of the publication if it is a book. You must use information from at least two books. If it is a website, you must list the URL, Page title, Website name, Author (if available), and date you accessed the site. It must be a reputable site to be used for report writing.



Due dates:


3/13: Choose your topic by this date. Have it approved both by your parents and by Deric. This topic may not change after this day.


3/20: Preliminary outline due long with a bibliography of at least two sources.


3/27: At least one paragraph on a famous scientist associated with your field due. You should all be pretty good at biographical writing by now.


4/10: A paragraph due explaining why I should care about your topic. This will hopefully help you write a memorable report and will come in handy when crafting your conclusion.


4/17: Complete outline due along with bibliography of at least four sources.


4/24: Turn in a paragraph explaining what information is proving to be the hardest to find, so I can help you.


5/1: Demonstration placard, explaining the demonstration and how it shows your concept due.


5/8: “Final” Draft due. This means that all components and sections are due except the demonstration itself.


5/15 Actual Final draft due
