¨When scientists approach a problem to solve, they will often start by gathering information. You and your friends decide to do the same. The park ranger helps out by giving you a map of the park with information about the surrounding areas.¨

1.What information can you get from this map that is relevant to the problem being solved?

2.What further information do you need to gather to solve this problem? What investigations do you think you should conduct in order to test your predictions?

Red beryl is one of the rarest minerals in the world. Because it is so rare, red beryl is about 1000 times more valuable than gold. Read the passage that describes how red beryl forms. Use the information to draw an inference about why red beryl has been found in only four places on Earth.


It takes several steps for red beryl to form. First, a volcano with lava rich in topaz rhyolite erupts. Volcanoes with this type of lava have been found only in the United States, Mexico, Russia, and Mongolia. If the lava cools at just the right speed — not too quickly and not too slowly — it will shrink and form large gaps. The gaps fill with hot volcanic gases rich in beryllium, a rare element. Over time, surface water seeps into the cracks and reacts with the gases, forming red beryl crystals.

Many flowering plants must be pollinated by bees to reproduce. Scientists have found that different kinds of bees can see different colors. This affects which flowers they pollinate. For example, bees that can see yellow are more likely to pollinate yellow flowers. Bees that can see red are more likely to pollinate red and orange flowers.
Suppose a large population of bees that see red lives in a meadow. How would the bees most likely affect the meadow's plants?


A.
Most of the flowering plants would have red or orange blossoms.

B.
A few of the meadow's plants would begin growing yellow flowers.

C.
The bees would not affect the meadow's plant populations.

D.
Many of the meadow's plants would stop blooming.
