Such sample could be obtained from ponds or lakes. If you want, you can also go to the ocean to examine the algae underwater. Seaweeds are the most widely known protist and large enough to see. To see microscopic protists, you should go to a local pond or stream.

For radioactive dating to be possible, the sample must contain a measurable amount of a radioactive isotope with a known decay rate. The sample must be isolated from sources of contamination that could affect the accuracy of the dating. Additionally, the sample must have remained a closed system since the radioactive isotopes were incorporated, in order to accurately measure the decay products.
