Honeybees (Apis mellifera) play a vital role in U.S. agriculture as pollinators of several crops, including carrots, almonds and apples. Pollination is the result of honeybees' ability to remember foraging sites. This study investigated honeybee memory endurance using the relay landscape learning method. Honeybees (n=1,000, Day 0) were released 0.8 kilometers from the experimental hive in opposite directions, 500 for the relay and 500 for the control. On Days 1, 3, 6 and 9, 40 relay and 40 control honeybees were recaptured, repainted, and re-released 1.8 kilometers from the hive.
"Suddenly, Earth began shaking and quickly got louder by the second." This seventh-grader from New York paints a vivid picture of earthquakes, from how they form to contemporary safety measures.
This discussion reviews how scientists define populations, and in particular, bighorn sheep populations.
This activity exposes students to the causes and consequences of inbreeding in animal and human populations.
This activity extends part 1 by reassigning students to new groups to present the case study completed in part 1, and then to complete the remaining case studies.
Discusses habitats and populations in the context of daily life and bighorn sheep.
Introduce students to the use of road salt to keep roads clear of snow and ice, potential problems with road salt runoff, and to Dr. Sujay Kaushal, the scientist who conducted the study on salt in the Baltimore water supply.
A close look at how added salt affects living things, at the cellular, organismal and ecosystem level.
Learn where our water comes from and how runoff from roads impacts the environment.
Students learn how research studies are designed, what data to collect and graph to best answer a research question.
