Goldilocks+-+Mariela

===Hello everyone you are now watching WHAT THE BED? For people who may not know this a science show where we could observe, make inferences, look at the IV, DV,levels of IV, constants on different types of beds. Today in this segment our own reporter Goldilocks Holmes was at the Big Bear House or as you may know it by B.B.H. She was there studying the type of bed in which bears sleep most comfortable in. "Thank you Mari" We are now her at the front of the B.B.H looking in on studying the type of bed, bears feel most comfortable in. Come on lets go in. Here we observe (something you can sense) that there are three different beds. Now everyone I infer( something you decide or think about after you observe it) that the bed that looks dirtier in the room is the one that is used more often since when you use something often, you get it dirtier sooner then what you don't use that often. Our hypothesis (is a reasonable prediction on what might happen based on your knowledge and observations) IF type of bed changes, THEN the regular mattress will be mostly slept on than on the water bed and air mattress BECAUSE the regular mattress is often used. Now i am looking in at the IV(the thing that changes on purpose) which is the type of bed. There are 3 different types of bed these are called the levels of IV (descriptions of "set ups")which are the air mattresses the regular and the water bed. My DV (what you measure) is going to be the amount of sleep on bed or how much sleep you get on each bed. Our units of measurements (what you measure in ) is going to be in hours.Remember kids we have to have constants (stay the same ) the height of the bed and the location of bed. Now our purpose(states the reason for the lab) "The purpose of this experiment is to determine the effect of the type of bed on amount of time slept in the bed. Now we have tried out this investigation here at the B.B.H where the Big Bad Bears sleep. Now back to you Mari. Thank You Goldilocks. This segment is almost over but before you leave make sure you remember kids to stay tuned for the next show see you next time on WHAT THE BED? goodnight everyone ===
