Conclusion
Answer the following questions in complete sentences, and justify your responses.
1. After how many time intervals (shakes) did one-half of your atoms (candies) decay?
2. What is the half-life of your substance?
3. If the half-life model decayed perfectly, how many atoms would be remaining (not decayed) after 12 seconds?
4. If you increased the initial number of atoms (candies) to 300, would the overall shape of the graph be altered? Explain
your answer
5. Go back to your data table and for each three-second interval, divide the number of candies decayed by the number
previously remaining and multiply by 100. Show your work

Air pressure is measured in pascals. for a professional american football game, the ball should be inflated to about 90,000 pascals. scientists studied the effects of air temperature on the pressure inside american footballs by taking these steps: 1. prepare 100 footballs. 2. measure each football's air pressure. 3. divide footballs into 10 groups. 4. place the groups in different lockers cooled to different air temperatures. 5. after 12 hours, remove the footballs from lockers. 6. measure each football's pressure again. 7. compare the new pressures to the starting pressures. what two terms best describe the variable "air pressure inside the football" in this experiment? independent, qualitative independent, quantitative dependent, qualitative dependent, quantitative
