Students in Ms. Wong's 6th grade science class were asked to design and build a model of some part of the human skeleton. The challenge was to make a model that actually moved like the part that was being modeled. The students were given the materials listed in the table above and were asked to work in groups of 3 - 4 students. One group constructed the hand you see here:

The students in this group constructed a hand with three fingers and a palm. Noticed the arrows pointing to the nylon cords. The cord feature was added to represent the bones in the palm of your hands. Another student group commented on this design. "You should put the cords in the straws and then tape them into the palm."

What would this change represent in the prototype hand?

A) bones (straws) and skin (cords)
B) nerves (cords) and bones (straws)
C) bones (straws) and muscles (cords)
D) muscles (straws) and nerves (cords)

Pls in your opinion, what are the limiting factors that might affect the growth or diversity of our ecosystem? respond to this question in claim, evidence, reasoning format. 1. make your claim (i are the limiting factors that might affect the growth or diversity of our 2. follow the claim with 3 pieces of evidence. evidence may be taken from the reading, the videos, previous lessons, or googled answers. site sources, too. 3. use reasoning to explain why you chose your evidence.

Recently, crops of vegetables such as lettuce and green onions have been contaminated, while they are still on the farm, with bacteria that cause food poisoning. how will science influence the way the government responds to prevent an increase in food-borne diseases? because science has shown that lettuce and green onions are not nutritionally valuable, the government may pass laws that ban the sale of lettuce and green onions. because science has shown that there is no way to prevent bacterial contamination, the government may pass laws that punish businesses that buy lettuce and green onions. because science has shown that the washing of hands prevent the spread of infectious diseases among people, the government may pass laws that require hand washing by everyone who handles food. because science has shown there are ways to find the source of the contamination, the government may pass laws that require farm practices that reduce the contamination of lettuce and green onions.
