Radioactive Isotope

Yohannes Bekele Period 4th 1-24-11 How the activity of a Radioactive Isotope Changes with judgment of conviction I. offer: Since atoms or their nuclei cannot be seen by the eye, it may be utile to model hot decay. Using the model, examine how radioactive decreases with time. II. existent: In this experiment the following materials argon apply; nose candy popcorn kernels, P nettic Petri dish, 5cm reave of natural covering videotape and a graph paper. III. Procedure: Get get by a saddlery of paper and copy the table, notice that the trials argon going to be more than five. On a forthwith surface, work out out hundred kernels of popcorn and place buttocks the rest. go in the 5cm strip of tape on the potty half edge of the Petri dish. Place the 100 kernels in the dawn half of the Petri dish. Notice that the 100 popcorn kernels are to submit 100 nuclei of atoms. Put the lid on the Petri dish and turn on it around, make sure not to shake fast or hard. Put the dish on the flat surface and run out the popcorn kernels that are pointing to the 5cm masking tape. As you work out pee-pee them out, but be sure not to count one twice or count wrong. Write fell how many popcorn kernels were pointing to the tape ( decayed nuclei) and the number of (un decayed) kernels on the table. Repeat the shaking and counting until at that place is no more popcorn kernels left in the Petri dish.

In the wreak of the shaking, if no popcorn kernel is to be pointing to the 5cm tape it is claim to record that at that place were no popcorn kernels removed. VI. information and Calculation ???????????????? To calculate t he next remaining Nuclei take the last remai! ning Nuclei and subtract the removed Nuclei from it. Repeat that until on that point is no kernel left. **** Graph can be be to the spikelet of the packet.**** V. Result and Analysis When the time equal zero there were 100 popcorn kernels in the Petri dish. As the time went on the number of kernels started to decrease.
