Baby Chicken Food Consumption
1. Baby chickens, like all babies, require a constant source of food. As chicks grow, more energy is
required for daily activities, and their food requirements increase. This data table reports average food
eaten by a group of 10 chickens over a 5-day period.

1 1.0
2 3.2
3 6.5
4 10.6
5 15.4
2. Elodea, a water plant commonly found in aquariums, gives off oxygen bubbles when growing in bright
light. Students in a biology class noted that if a light were placed at different distances from the plant in
an aquarium, the rate of bubble production varied. This data table shows the average results from
several trials.
** Students forgot to record the distance

3. Gibberillic Acid is a plant hormone that controls stem length.
Students completed an activity to determine how the amount
of gibberillic acid affects plant growth. This data summarizes
the results of this activity. the effects of a growth hormone
(gibberellic acid) on plant height.
A 0.1 molar solution was used in all experiments.

-
Estimate plant height at 10 mL gibberellic acid.
-
Estimate plant height at 25 mL?=.
-
Why is plant height at 60 mL not consistent with the rest of the data?

Pinto Bean Germination Rate
A team of scientists tested the effects of temperature on the germination rate of pinto beans by placing three sets of 100 pinto bean seeds in temperature-controlled chambers.
-
Chamber A was set at 15 C
-
chamber B at 20 C
-
chamber C at 25 C
