6 Grade - Nature of Science 1. Your class is making paper boats Students think that the kind of paper and the design of the boat may
affect how long each boat floats. The students first test the kind of paper affects how long the boats float
They make several boats out of different kinds of paper, using the same design. Why is important that all
the boats have the same design? (SC.6 N 1.1)
a) What is the independent vanable?
b) What is the dependent variable?
b) What are the constants?

Biochemistry, it deals with the chemical constitution, the breakdown and the synthesis of plant and animal products.

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.
