  • The Secret of Floating Objects

    Assignment Instructions Childrens Chemistry Book

    You will create a childrens book that explains the chemistry concept of density in a simple and engaging way. The goal of the book is to teach children how scientists understand why some objects float and others sink.

    1. Choose a target age range of 610 years old so the language and explanations are appropriate for young readers.
    2. Create a cover page that includes the title of the book and an illustration related to floating and sinking.
    3. Create 810 pages for the story (not including the cover). Each page should contain:
    • 13 short sentences
    • an illustration that helps explain the idea.
    1. Begin the book by introducing a simple situation children recognize, such as placing different objects in water and observing that some float while others sink.
    2. Explain that scientists use a property called density to understand this behavior.
    3. Describe density as how much matter is packed into a certain amount of space.
    4. Introduce the idea that density compares mass (how much matter something has) and volume (how much space something takes up).
    5. Show the basic formula in a simple way:
    6. Density = mass volume
    7. Include clear examples that children can easily understand, such as:
    • a rock sinking in water
    • a piece of wood floating
    • objects that have more matter packed into a small space being more dense.
    1. Use correct scientific vocabulary, but explain each idea using simple and clear language appropriate for children.
    2. Include illustrations on most pages to help readers visualize the concept.
    3. End the book with a short conclusion page that reminds the reader what density means and how it helps explain floating and sinking.
    4. If you use images that are not your own or that are generated with AI, make sure to include proper credit for the image source.
    5. Organize the final book in PowerPoint, Word, or PDF format so it can be uploaded as one file.

    The childrens book will be submitted together with a completed cover sheet that includes the students name, book topic, book title, age range, and any references used.

    NOTE ALL INFORMATION AND REFERENCESES ARE INCLUDED IN THE OUTLINE AND MUST BE USED:

    General Presentation Requirements:

    • There must be a visual element (e.g., photos, videos, graphs, figures).
    • Your presentation must contain approximately 10-15 slides (excluding references) and run approximately 5-10 minutes.
    • Please note that less than 10% of your presentation should contain direct quotes.
    • Be sure to properly cite your work, both internal to the presentation as well as within the reference slide (this includes photos, graphs, figures, videos, etc.).
    • All references listed on the reference slide should be cited internally within the presentation, and vice versa.

    Introduction Slide(s) – include ALL components below:

    1. Molecule/substance Introduction
    • The common and IUPAC name of your molecule/substance. Please see for help with scientific names if needed.
    • Where you can observe your molecule/substance in society and/or in nature.
    • A brief discussion on why you chose your molecule/substance.
    • If possible, a picture and/or video of you safely observing your molecule/substance in the field. If you cannot safely observe it, please include a couple of images from the internet.

    Description:

    • You must include a physical description. You can use your personal observations from photographs. If you cannot safely observe your molecule/substance, you must research.
    • Physical Characteristics (appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, etc.)
    • Chemical description: You will need to research the chemical properties of your compound/molecule).
    • Chemical Characteristics (stability in air or other environment, flammability, volatility, etc.)

    Discovery:

    • Describe the initial discovery of your molecule. Who discovered the molecule, when, how, etc.? Some compounds are part of a larger substance/plant. If this is the case, describe the isolation of your specific compound. The isolation refers to the initial time your molecule/substance was discovered from its raw materials or isolated from its .
    • Usage and benefit or harm to society
    • Where has your molecule/substance been used. Is it used regularly or is has it only been used on occasion? If your compound is one that we ingest when eating, include information on foods it’s commonly found in.
    • Write about the benefit or harm to society caused by your molecule/substance. Many compounds can be used as bioweapons or have both positive and negative impacts. Other compounds have had benefits as medicines or have caused harm as illicit narcotics. All of these are good ideas to start out thinking about, so I’d like you to discuss these impacts on society, the future, and in any way you can think of that they may be beneficial or harmful. Please see here for some hints on .

    Conclusion – include ALL components below:

    • Four to six points that sum up the main topics of the presentation that you have in your outline.

    Reference Slide(s) and Internal Citations include ALL components below:

    • Internal citations: This is not just a separate section; rather, referencing should occur throughout the presentation via parenthetical citations any time you paraphrase, make direct quotes, or use visual components from other sources. Please be sure to cite any language, images, videos, etc. in the presentation that should be cited.
    • Reference Slide: Your presentation should also have a final reference slide listing 5-10 credible sources researched for your presentation. NOTE: These are not included in the slide count for your presentation.

    also remember that

    Dear Students,

    Due to the unfortunate regional development, the staining and de-staining cycle could not be done.

    I have therefore attached 4 pictures of reference sample gels after these cycles for you to prepare your lab reports. Please follow the below allotments.
