Assignment: Determining Half-life Exploration Data Table Trial Amount Decayed Amount Left 1 2 3 4 5 6 Graph Using the data from the table, make a graph of the number of atoms remaining after each trial. Questions 1. How many trials did it take for half of the Virtualium atoms to decay? 2. Suppose each trial equals 1,000 years. What is the half-life of Virtualium? 3. Suppose each trial equals 1,000 years. After half (50) of the Virtualium cubes were removed from the box, about how long did it take for half of the rest of the cubes to decay? 4. Imagine you have a radioactive sample containing both Virtualium and decayed atoms of Virtualium. After analysis, you find it contains 10 atoms of Virtualium and 40 decayed atoms. How old is your sample? (Hint: You must use the half-life of Virtualium determined earlier in the activity.)

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
