Fast Relief: Warm or Cold?

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