This demonstration will prove to students that gas does have mass, and that all gases do not necessarily have the same mass. Vinegar and baking soda will be mixed in a pitcher to create carbon dioxide gas. An easy to build, home-made scale will be present with paper bags on each end. After mixing the vinegar and baking soda, the gas from the pitcher will be “poured” into one of the paper ...

Record all the digits. Using a dry spatula, transfer approximately 1 gram of ‘Baking soda, sodium hydrogen carbonate (NaHCO3)’ into the test tube. Using the same scale, find the exact mass of ‘test tube, beaker and Baking soda’. Record all the digits. Mass of the ‘Baking soda’ should be no more than 1.500 g. Clamp the test tube at ...

Students conduct the vinegar/baking soda experiment to see if mass is conserved. Application. Students answer questions related to the day’s experiences. Assessment. Students will be assessed on their ability to make inferences in science based on careful observation. T-charts will be collected at the end of the day for assessment. Lesson 4 at a glance: Activating. Students go a graffiti ...

The substances (baking soda and vinegar) should be fizzing and bubbling. A chemical reaction takes place that is not reversible. The bag will fill with gas (carbon dioxide) produced by the reaction. The mass of the bag should be the same. The match remains lit in the control bag because oxygen is present. The match extinguishes in the bag where the reaction has occurred because carbon dioxide ...

The total mass of the bag, vinegar, baking soda, and measuring cups (all of the materials) was the same before and after the reaction . 5. How was your experiment different from the teacher demo in part A? Student answers will vary but should include the fact that the teacher experiment allowed gas to be released into the room while the student experiment trapped the gas. Expand: Using the ...

Her baking soda inquiries from baking college began to resurface and she realized that the reaction of baking soda and vinegar caused something to be released into the air. Draw a picture of the device below. Explain how it works. Annie realized that the reaction of the baking soda and vinegar had caused a gas to be released into the air. This gas was carbon dioxide. When baking soda was mixed ...

At the same scale place one large scoop of baking soda (NaHCO3) into the test tube, then using the same scale as before, weigh the test tube with the baking soda. Record this mass in the table at right. (You should be able to figure out what mass of baking soda is in the test tube.) 3. Holding the test tube nearly horizontal, shake the baking . soda gently so that it spreads out a bit as shown ...

250 g baking soda in a plastic container (Carefully mix the baking soda with a little water to make it a little damper than the consistency of snow – 4 parts baking soda mixed with 1 part water is quite good. The baking soda needs to be damp enough to stay in the lid when it is tipped upside down.) 1 litre of white vinegar in a sipper bottle for easy pouring. Coloured card. Tape . Spoons ...

Place the bottle with the glove attached in a large plastic container and transfer all of the baking soda from the glove to the bottle as quick as possible. The acid-base reaction will form carbon dioxide, which will blow up the glove. Pop the glove with scissors for a grand finale. Some excess baking soda will disperse in the air. Explain the chemistry to the students (see “What Happens and ...
