    • Students will explore acids and bases throughexperimentation, observation, predictions and questioning to describeobservable chemical changes of matter through kitchen chemistry withbaking soda and vinegar.
    • • State Standard• Fourth Grade Nature of Science• Indicator 2: Apply the skills necessary toconduct scientific investigation.• Common Core• Writing Standard Grade 4• 3: Write narratives to develop real orimagined experiences or events usingeffective techniques descriptive details, andclear event sequences.• ISTE NETS• 2. Communication and Collaboration• d. Contribute to project teams to produceoriginal works or solve problems.• 4. Critical Thinking, Problem Solving, andDecision Making• b. Plan and manage activities to develop asolution or complete a project.
    • • Outcome• Use scientific investigation toquestion, predict, develop a plan, managedata, make an evidence based conclusion, reflectand apply to everyday activities. Share findingsthrough a digital documentary.• Meaningful Learning• Active – Plan and manipulate conditions of theexperiment to draw conclusions about the powerof chemical reactions.• Cooperative – Work as a group todocument, explore, and explain the chemicalreaction.• Authentic – Apply what learned to baking of quickbread/cake and household cleaning.• Activities & FinalProject• Conduct an investigation to explore the power ofthe chemical reaction between baking soda andvinegar with a group. Keep an individualscientific journal of the process on Spiderscribe.Produce, as a group, a multimedia documentary

    • • ProceduresGain Attention –class activity• Experiment 1: Spread baking soda on a plate. Have 2 to 4 smallcups of vinegar colored with different colors of food coloring. Dropcolored vinegar on to soda with a medicine or eye dropper andwatch the reaction.What happens? Why does it happen? What does it look like? Whathappens when the different colors touch? Is there any energy or powerin the reaction? How strong is it?• Experiment 2: Fill glass with 1 cup of water. Place ¼ cup of vinegarin the glass and stir. Add 1 teaspoon baking soda to the glass andimmediately toss in 5 kernels of popcorn. Popcorn will dance oncarbon dioxide bubbles. Experiment with different sized and shapedglasses.During class experiments model scientific journaling techniques usingSpiderscrib.Use pretest to determine students prior knowledge. Introduce acids andbases to class, exploring ideas of pH and chemical reactions.Review safety guidelines when conducting an experiment, expectationsof group work and journaling procedures. Introduce final projectrequirements.Explain that it is a documentary of whole investigation that is to includestill images or video. Small groups should be assigned so that they candiscuss a plan of action to capture the investigation. Action reportshould be presented to the teacher so that any questions orclarifications maybe made prior to beginning experiment and to makesure the appropriate equipment is available.As a class discuss the question/problem/purpose of the experiment.Introduce or assign any additional research information as required.Break into small groups to complete either the rocket or balloonexperiment. Both experiments should be equally represented so thatthe teams can collaborate on the experiments. Individual teams shouldmake predictions and formulate a plan of action including a supply list.PreparationsProceduresAssessmentsExtensionsWeb Links
    • • Small Group Experiments:• Rockets• Baking Soda, 16 oz. plastic bottle (and other bottle of varioussizes and shapes), Vinegar & Tissue Paper, eye protection,outside location• Fill the bottle with around an inch of vinegar. Pour somebaking soda into a piece of tissue paper. Place paper intobottle and replace the cap. Shake bottle, place on groundupside down standing on the cap, stand back. The pressurewill build up causing the bottle cap to pop off and the bottleinto the sky. Experiment with different quantities of vinegarand baking soda and rotate the bottle so that the cap is up.Document results.• Balloons• Baking Soda, Vinegar, plastic bottles (various sizes andshapes), balloon, 2 funnels, eye protection, outside location• Fill about 1/3 of bottle with vinegar using the first funnel.Using the other dry funnel pour baking soda into your balloonso that it is about ½ full. Cover the top of the bottle with theballoon being careful not to dump soda into the vinegarprematurely. When ready lift the balloon and let the bakingsoda fall into the vinegar. Watch balloon expand and blowup. Experiment with different sized balloons, bottles andquantities of vinegar and baking soda. Document results.PreparationsProceduresAssessmentsExtensionsWeb Links
    • • Scientific Journal• Components• 1. Questions, Problem, Purpose• What is a chemical reaction? How do you know a chemical reaction has takenplace?• How much power does the chemical reaction between baking soda and vinegarhave? How can we measure it?• What is baking soda and vinegar and why do they react?• Can this reaction be useful to me personally?• 2. Prediction• Based on what I know now, what will happen and why when baking soda andvinegar are mixed together? Does this reaction have enough power to make aplastic bottle shoot into the sky or expand (blow up) a balloon?• 3. Planning• Create an action plan for beginning the experiment. Revisit as necessary andadjust as new information becomes available.• 4. Observations, Data, Graphs, Drawing, Video, Audio• What did we do and how did we do it? Additional information, expanded andinteresting topics researched to help gather data.• 5. Claims and Evidence• Make an evidence based explanation regarding their investigation.• What claim can we deduct from the investigation and what supporting evidencedid we find.• 6. Conclusion• What is our “final answer”?• 7. Reflection• Share with classmates, evaluate process, new questions, why is this importantto me?PreparationsProceduresAssessmentsExtensionsWeb Links
    • • Once the experiment is complete and data collected and put intographs, charts or drawings. Have the groups that did the sameexperiment share their findings with each other and discusssimilarities and differences between the procedures and findings.Claims and evidence should be recorded in their journals, as wellas, any discussion notes.• As a large group discuss the investigations and what evidence thesmall groups have found. Break into small groups to discussindividual investigation conclusions.• As a large group discuss individual conclusions and reflect on theinvestigation, what was learned, how it applies to everyday life.• Provide time to groups to review the investigation and create adocumentary of the experience usingpowerpoint, perzi, slideshare, or other presentation format.• Share presentations and have group answer questions from theaudience.• As a large group discuss the usefulness of this investigation in dailylife. Make a plan to investigate further baking and/or cleaning withbaking soda and vinegar.• Reflect as a large group on the whole experience of creating adocumentary.PreparationsProceduresAssessmentsExtensionsWeb Links
    • • Assessments• Pre-Test• What is an acid? What is a base? What happens whenthe two are mixed together? Do you think that thisreaction could blow up a balloon or fuel a plastic bottlerocket?• Self Assessment of Group Participation• Evaluate your participation in you group by answer thefollowing questions with: All of the time, Most of thetime, Some times or Not at all.• Did you stay focused on the task and be counted on byyour fellow team members?• Did you complete all your assigned tasks withoutdepending on others to do the work?• Were you respectful during discussions, when askingquestions, and interacting with team members toproblem solve?• Did you help in gathering information and sharing ideasthat match the group’s goal?• Did you have a positive attitude about the project andthe work of others?• Individual Assessment of Scientific Journal• Are all the components of the journal clearly presentedin an organized and easy to understand format usingSpiderscribe.• Group Assessment of MultimediaDocumentary of Investigation• Presentation RubricPreparationsProceduresAssessmentsExtensionsWeb Links
