Exemplar
This graph is shows the number of ice cream sandwiches that were sold in the cafeteria during a
week-long period. A total of 69 ice cream sandwiches were sold during this period. The most
number of ice cream sandwiches sold were on Monday (16 sold) and Friday (19 sold). The least
number of ice cream sandwiches (4) were sold on Thursday. Based on the data in this graph, the
cafeteria manager should have her order of ice cream delivered on Thursday –in time for the large
sales on Friday and Monday.
Erosion is responsible for a constant transfer of sediment in a river from
locations upstream to locations downstream.
Explain how sediment affects a river. In your explanation, be sure to
include how
• flooding might affect sediment
• sediment might affect the river habitat

During one year the algae population decreases in the Chesapeake Bay.
Below is a partial Chesapeake Bay food chain.
Explain how a large decrease in the algae population will most likely impact
the bay ecosystem. In your explanation, be sure to include
• the roles of the organisms in the partial Chesapeake Bay food
chain
• the possible effects of a decrease in the algae population on the
plant and animal populations

Bees
Florida has more than 250,000 bee colonies. Half of them are moved to the northern states
in the summer. Florida is one of the nation's top producers of honey. Bees must know a lot
about geometry. Their honeycombs are perfect six-sided cells. In winter, bees flap their
wings inside the hive to keep it warm. The hive can have a temperature of 91oF to 97oF.
Bees that find food (nectar) return to the hive and do a “waggle” dance. This dance tells
other bees the distance, direction, quality and quantity of food at the nectar source. Worker
bees are all female. They can fly as far as 3 &frac12; miles from their nest to find food. Their top
speed is 15 mph. A typical bee colony contains 20,000 to 30,000 bees. In one year, a
colony can collect more than 260 pounds of nectar that will be converted into honey.
What would happen if honey bees disappeared? What percentage of the agricultural crops
produced would we lose? What types of Florida commodities would become unavailable as a
result?
