5th Georgia Milestones Review

According to Discover Magazine, crows have the ability to remember the faces of humans they associate with a bad experience. A research team wore masks while they captured, tagged, and released a small group of crows. Other crows that saw the capture and tagging dive bombed the researchers and squawked to alert the danger. The researchers then tested both groups of crows to see how they would respond to the masks over time and found that there was a reaction to the mask.

Which statement BEST represents a question a student should ask to compare the behaviors of both groups of crows in the study?

• Do the crows respond because they don’t like masks?

• Is the squawking sound different among the groups of crows?

• How are the crows able to recognize a mask rather than a face?

• How might the crows respond to a mask not worn during the tagging?

Biologists working in dry, bare Arizona deserts have found life just below the surface. In many areas, small clumps of sand are held together by strands of tiny bacteria. After heavy rains, the bacteria germinate and grow. They form mats that trap sand during the wind and rain of the storm season. The biologists claim that the bacteria are beneficial to the ecosystem. Which argument BEST supports their claim?

• The bacteria slow the rate of soil erosion.

• The bacteria add vital nutrients to the soil.

• The bacteria store water for the dry season.

• The bacteria weather large rocks into soil.

They would also ride their pony Beauty on the beach. Beauty loved to run near the waves and splash water all around. She was brown and gold and had a lovely tail.Bella would also allow other children to ride Beauty because she was friendly and safe to ride.

One morning as they were leading Beauty to the beach, they found her walking very slowly. Bella examined Beauty's hooves and said, "Her hoof looks swollen, let's take her back home."

They took Beauty back home and called the local vet, Dr. Barry. Beauty neighed and looked up when she saw Dr. Barry. She was fond of him because he was very gentle with her.m"You need to see that her hoof is rested for a week. She will be fine then," said the doctor. When the other kids on the beach heard that Beauty was not well, they came to see her and brought her carrots. They knew she liked them.
