    Fast Relief: Warm or Cold? Fast Relief: Warm or Cold? Presentation Transcript

    • Fast Relief: Warm or Cold?
      By Michelle Santoy 4th grade
    • Many kids eat a combination of foods that give them stomach aches and they want something that will make them feel better fast.
      They can take an Alka-Seltzer. But what is the fastest way to make it work?
      Problem
    • How does the temperature of the water affect how the Alka-Seltzer works?
      Question
    • Warm water will make the Alka-Seltzer produce gas faster.
      Hypothesis
    • 1. Alka-Seltzer
      2. Water
      3. Microwave
      4. Timer
      5. Paper
      6. Pencil
      7. Thermometer
      8. Camera
      9. Clear glasses
      Materials
    • Get Alka-Seltzer
      Get Water
      Heat one glass of water for a little bit
      Fill glass with room temperature water
      Put a thermometer in each glass
      Add ice or heated water to make desired water temperature ( over 103 for hot or under 50 for cold)
      Write down temperature
      Put an Alka-Seltzer in glass and start timer
      Take a picture of the Alka-Seltzer producing gas
      Stop timer when the Alka-Seltzer stopped fizzing
      Write down the time
      Repeat steps 3 - 10 for different water temperatures
      Procedure
    • Data
    • Data—Observation
      Not fully dissolved
      Fully dissolved
    • The warm water made the Alka-Seltzer dissolve in an average of 22 seconds, while in the cold water it took an average of 1 minute and 52 seconds for the tablet to dissolve.
      The tablet more fully dissolved in the glass of warm water than in the glass of cold water.
      Results
    • My hypothesis that warm water will make the Alka-Seltzer produce gas faster was correct.
      If a person has a stomach ache, she should choose warm water to drink an Alka-Seltzer because it will make the tablet dissolve faster and more fully.
      Conclusion
