Which of these is NOT an example of a renewable energy source?
-
Wood
No. Because we can grow more trees, wood is a renewable energy source. -
Coal
Yes. It takes millions of years for coal to form, so it is not considered a renewable energy source. -
Hydroelectric power
No. Thanks to the water cycle, water is added to the lake above the dam, making this a renewable energy source. -
Wind energy
No. Wind energy is constantly renewed by uneven heating of the Earth.

Which part of your body comes closest to serving the same function as a flower?
-
Sensory organs
No. Plants can sense their surrounds just as well without flowers. -
Reproductive organs
Yes! Flowers are the reproductive organs of the plant. While most animals are either male or female, most flowers have both male (stamen) and female (pistil) reproductive organs. In this photograph, the male stamens are the green stalks with the yellow ends. The female pistil is the white structure just below the stamens. -
Digestive system
No. Plants make their own food, so they do not need a digestive system. -
Skeletal system
No. The stiff cell wall of a plant cell serves the same function as our skeleton.

Liver
Yes! The liver produces bile, which digests fats. -
Gall Bladder
No. The gall bladder stores the bile, but does not produce it. -
Pancreas
No. The pancreas produces insulin to digest sugar. -
Thyroid
No. The thyroid produces several hormones which control growth and metabolism, but it does not produce bile.

I used this piece of calcite to scratch this penny. Then I used the penny to scratch the piece of calcite. What does that tell us?
-
It tells us that I did the test wrong.
No. The test was done correctly. -
It tells us that they both have the same hardness.
Yes! You test the hardness of a mineral by testing to see what will scratch it. If two substances scratch each other, they have the same hardness. -
It tells us that calcite is not a mineral.
No. Scratching a specimen will not tell you if it is a mineral. -
It tells us that calcite has cleavage.
No. You do not test for cleavage by scratching a mineral.

I used a Density Column to show that olives are denser than cherry tomatoes. To follow proper scientific procedure, the experiment needs to be checked by repetition and replication. What is the difference between repetition and replication?
-
Repetition means that I do the same experiment again. Replication means that other people do exactly the same experiment again.
Yes! To confirm your results it is important for you to repeat exactly the same experiment again (repetition) and then for other people to do exactly the same experiment again. (replication). If any of the results from repetition or replication are different from your original data, your original results are NOT confirmed, and you need to do more work. -
Repetition means that I do the same experiment again. Replication means that I do the experiment again after correcting errors.
No. Replication is when other people to do exactly the same experiment. -
Repetition means that I do the same experiment again. Replication means that other people try to improve on my experiment.
No. Replication is when other people to do exactly the same experiment. -
Repetition means that I do the experiment again after correcting errors.. Replication means that other people do exactly the same experiment again.
No. Repetition means that I do the same experiment again.
