Conduct a Chemistry WDI: Design and perform a chemistry experiment using the Well-Designed Investigation model. Some ideas for testable questions are: Do sugar crystals grow bigger in certain type of liquid (i.e. water, apple juice, 7-Up)? Do different liquids affect the consistency of oobleck? Do different types or amounts of salt affect the freezing of ice cream? Do different glues change the consistency of homemade silly putty? Do Mentos react differently in different types of soda? How does the solvent affect the results of chromatography? Include the notes you took while you did your research (5 points) Complete all parts of the WDI: o o o o o o o o o o Background Research–at least 10 background facts about your experiment (5 points) Materials (1 point) Testable Question (1 point) Hypothesis - written in correct form (1 point) Independent variable & dependent variable identified (1 point) Controls identified – at least 3 (1 point) Procedure - a detailed list that would allow someone else to repeat your experiment (2 points) Data tables (2 points) Data analysis (2 points) Conclusion that refers back to testable question and is supported by data (2 points) Create a properly formatted bibliography with at least 2 sources (2 points) 2. Create a Periodic Table: Create a periodic table out of ordinary objects. You may cut pictures out of catalogs & magazines or you can use the objects themselves. Your periodic table must be organized in a way that mimics the Periodic Table of Elements. Include the notes you took while you did your research (5 points) (families) that have characteristics in common (8 points) periodicity within each group [a characteristic that changes as you go across in a period] (3 points) 4 periods that have characteristics in common (4 points) Assign each group a descriptive name (1 point) Assign each period a descriptive name (1 point) group (1 point) Create a properly formatted bibliography with at least 2 sources (2 points) 3. Research an Element from the Periodic Table: Display the information from your research in a creative way. Be original; use your imagination! A couple of ideas are a PowerPoint, a wanted poster, a magazine ad, a baby book, a trading card, etc. Include the notes you took while you did your research (5 points) Display the basic information about your element (8 points) Name of element Element Symbol Who discovered it When it was discovered Where it was discovered Atomic number Atomic mass ● Number of protons ● Number of neutrons ● Number of electrons ● Melting point ● Boiling point ● State of matter at room temperature ● Classification (metal, nonmetal, metalloid) ● Group (family name) ● Origin of the name Choose 6 of the following about your element (6 points) Other events that were happening in history when your element was discovered It’s chemical properties What it is commonly used for in everyday life Ways it is used in the human body Dangers or hazards associated with it Where it can be found in earth’s atmosphere or crust Where it can be found outside of Earth (other places in the solar system or universe) Three compounds your element can be found in. Connections to everyday life Three other elements that are in the same group (family) A Bohr model with a description of what it shows Include at least 2 additional interesting facts about your element (2 points) 2 pictures of your element with a caption you wrote describing each picture (2 points) Create a properly formatted bibliography with at least 2 sources (2 points) 4. Investigate a Compound: Display the information from your research in a creative way. Be original and use your imagination! A couple of ideas are a PowerPoint, a wanted poster, a magazine ad, a baby book, a trading card. Some suggestions for compounds you can research are: baking soda, sulfur hexafluoride, sodium acetate, silver nitrate, sodium chloride, acetic acid, hydrochloric acid, butane, nitroglycerine, ruby, amethyst, sugar, carbon dioxide, sulfuric acid, acetylsalicylic acid, emerald, water, hydrogen peroxide. Of course, there are hundreds of compounds to choose from! Include the notes you took while you did your research (5 points) Display the basic information about your compound (9 points) ● Common Name ● Scientific Name ● Chemical formula ● Molecular weight ● Color ● Density ● State of matter at room temperature ● Boiling point ● Melting point Choose 4 of the following about your compound (4 points) 2 other compounds that are similar to your compound and how they are similar It’s chemical properties (how reactive it is and what it may react with) What it is commonly used for in everyday life Ways it is used in the human body Dangers or hazards associated with it Where it can be found in earth’s atmosphere or crust Who, when and where it was discovered Historical information about it; ways it was used in the past Folklore associated with it Include at least 2 additional interesting facts about your compound (2 points) 3 pictures of your compound with a caption you wrote describing each picture (3 points) Create a properly formatted bibliography with at least 2 sources (2 points) 5. Participate in a Matter Scavenger Hunt: Do some research to find 15 of the objects below that fit the following descriptions. The objects should be creatively displayed and labeled. For each object, explain why it is that type of matter. Note: All objects need to adhere to school safety guidelines. Please see your teacher if you have any questions. An element A compound An amorphous solid A crystalline solid A heterogeneous mixture A homogenous mixture A gas-liquid solution A malleable substance A solid-liquid solution A substance which has a volume of 1 cm3 An edible example of a physical change An edible example of a chemical change A mixture that can be separated by filtration A mixture that can be separated by some other method than filtration A substance with a density less than 1g/mL A substance with a density more than 1g/mL An acid A metal A non-metal An inert gas A transition metal An alkaline earth metal A toy which demonstrates a physical change The result of a chemical change A base with a pH greater than 9 A polymer A solid solution (alloy) A colloid Include the notes you took while you did your research (5 points) in a neat & organized display (3 points) - each description should be at least 1 sentence (15 points) Create a properly formatted bibliography with at least 2 sources (2 points) 6. Do you have your own idea? See your teacher to discuss it and create a rubric! Tips for a Successful Project: Choose topics and products that interest you. Organize your information as you research! Think graphic organizer or outline. Record bibliography information as you work. Pace yourself - don’t wait until the last minute. Ask if you have any questions. Revise and edit your written work. Turn in something you’re proud of! Some Useful Websites: These websites are a few good starting points for your research.
