1.Create a graph using your data from Table 2 and a computer program such as Microsoft Excel. On the x-axis plot Trial Number. On the y-axis plot Parent Atoms and Total Daughter Atoms. This means you will plot 2 x-y scatter lines on the same graph. Your graph must have a title, both axis labeled and a series label indicating which line is which.

2.Suppose the isotope your Skittles represented was uranium-238 and the trials represent the number of half-lives. How old was the sample at the end of your tests? Include your calculations.

3. Identify and describe similarities and differences between this experiment and radioactive decay in nature.

4. Define radioactivity decay.

Can someone please help me with these four easy questions? Below, I pasted the directions I used to conduct my experiment. Thank you! SHOW WORK!

Procedure

1. On a flat surface, count the number of Skittles that were in your bag. Record this number in Trial 0 of Table 2 as the number of Skittles S Up (Parent Atoms) and record 0 as all other values in Trial 0.

2. Place all the Skittles in your cup. Place your hand over the opening of the cup and shake it several times.

3. Pour the Skittles out on a flat surface, such as a table or countertop.

4. Count the number of Skittles with the S facing up. Record this number in Table 2. These Skittles represent the parent atoms. Place the parent atoms back into the cup.

Note: The S on some of your Skittles may be faded. Take care in counting which have an S and which dont.

5. Count the number of Skittles with the S facing down. Record this number in Table 2. The Skittles represent the daughter atoms. Set them to the side.

Note: The S on some of your Skittles may be faded. Take care in counting which have an S and which dont.

6. You should now have parent atoms in your cup, and a pile of daughter atoms on the side. Shake the cup several times.

7. Repeat Steps 2 - 5 until all your parent atoms have decayed. Record your data in Table 2.
