## Fast Relief: Warm or Cold?Presentation Transcript

• Fast Relief: Warm or Cold?
• 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.
