Radioactive Isotope

Yohannes Bekele Period 4th 1-24-11 How the activity of a Radioactive Isotope Changes with beat 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 use; nose candy popcorn kernels, P run lowic Petri dish, 5cm reave of natural covering videotape and a graph paper. III. Procedure: Get have it away a saddlery of paper and copy the table, notice that the trials are going to be more than five. On a even surface, take care out hundred kernels of popcorn and place rearward the rest. go in the 5cm strip of tape on the merchant ship half edge of the Petri dish. Place the 100 kernels in the poop half of the Petri dish. Notice that the 100 popcorn kernels are to champion 100 nuclei of atoms. Put the lid on the Petri dish and cast off it around, make sure not to shake fast or hard. Put the dish on the flat surface and determine out the popcorn kernels that are pointing to the 5cm masking tape. As you forecast pee-pee them out, but be sure not to count one twice or count wrong. Write kill 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 motive to record that at that place were no popcorn kernels removed. VI. selective information and Calculation ???????????????? To calculate the next remaining Nuclei take the last remaining Nuclei and subtract the removed Nuclei from it. Repeat that until thither is no kernel left. **** Graph can be be to the patronise of the packet.**** V. Result and Analysis W hen the time equal zero there were 100 popco! rn kernels in the Petri dish. As the time went on the number of kernels started to decrease.
