Topic: NATURAL SELECTION ACTIVITY
Simulate a case of natural selection in a predator-prey situation.
STEP 1 Gather your materials. You should have:
. 1 fork, 1 knife, 1 spoon, and a length of tape (each will be used toestablish the distinct predator "feeding apparatuses")· 4 cups (each will serve as a distinct predator's "mouth")· 3 types of prey (such as popcorn, macaroni, and kidney beans)· 1 clearly delineated habitat (such as a table, a box, or a roped-off areaof ground). 1 timer that allows for counting by seconds (such as a watch or cellphone)
STEP 2 Set up the predators. There is variation in predatory feeding apparatuses in this population. You will choose one of the available predator feeding apparatuses: fork, spoon, knife, or four fingers (with your thumb taped to your hand so that you cannot use it). You will also take a cup, which will represent the predator's mouth. Your goal will be to use your feeding apparatus to collect food and put it inyour mouth.
STEP 3 Set up the…

- Identify whether each of the statements is an Observation or a Hypothesis to explain an observation. 1) Golden toads laid their eggs in shallow pools of water between the roots of cloud forest trees. 2) Golden toad tadpoles lived in shallow pools of water on the cloud forest floor before developing into toadlets. 3) Over warm ocean water, clouds form higher in the atmosphere. 4) Golden toads had highly specialized reproductive habitat. 5) Golden toads were found only in the cloud forest of Monteverde, Costa Rica. 6) The fossil record and current trends show that highly specialized species with small populations and narrow ranges are highly susceptible to extinction. 7) Spring 1987 was the driest spring on record for Monteverde. 8) All the golden toad tadpoles might have died during the spring of 1987 because their pools dried up before the young could lead a fully terrestrial life. 9) The drier conditions at Monteverde in 1987 might have been caused by…arrow_forwardAlthough many chimpanzees live in environments with oilpalm nuts, members of only a few populations use stones tocrack open the nuts.
