quanitiative data
7
When suggesting improvements to an experiment , which one would be a poor option?
avoid human error by estimating instead of measuring with a scale
repeat at least 3 times
use more precise equipment
include more values of independent varible for a better idea of the pattern
8
In an experiment, the experimental group ...
is not subjected to experimental error.
is not exposed to experimental treatments.
is statistically the most important part of the experiment
is exactly the same as control group, except for one independent variable
9
Why do scientists take multiple readings?
To improve the reliability of the data
To increase accuracy
All of the above
To mitigate the effects of anomalous results
10
Which is NOT an example of a controlled variable?
light intensity
weather
O2 concentration
pH
11

gradient
grades
groups
gases

a possible explanation for a set of observations that can be tested
13

phytoplankton does photosynthesis and zooplankton does not
both float on the ocean surface
both live inside of coral
zooplankton are consumers which eat phytoplankton
17

18
Which is not an efficient way of changing light intensity?
setting one lamp at different distances
using different lamps

using a dimmer switch
19
Data expressed in terms of quantity or amount, such as in inches, meters, grams, degrees, etc.
repsonding data
immeasurable data
qualitative data
quantitative data
20
Explain why corals can bleach.
when zooxanthellae leave coral they take their pigments with them
zooplankton get stressed and leave coral
predators like the Crown of Thorns starfish can eat them
water gets too cold for zooxanthellae

be sure fish have friends in tank
prevent water spills and keep area dry around tanks
limit food so they don't grow too big
