Can bees distinguish smells inquiry

This inquiry examines whether bees can distinguish between different scents, specifically peppermint, anise, and lemon. The experiment trains bees to associate sugar water scented with anise oil to test their scent recognition abilities. By monitoring the number of bees entering scented versus unscented boxes, students will analyze the data and discuss the implications of their findings. The results suggest that bees can recognize all three scents tested. This study highlights the importance of scent recognition for bees' survival and efficiency in foraging.

  1. Can bees distinguish smells inquiry What is adaptive advantage scent discrimination?

  2. Hypotheses • Bees cannot recognize peppermint scent • Bees cannot recognize anise scent • Bees cannot recognize lemon scent

  3. Protocol • Train bees to come to a dish of 25% sugar water scented with anise oil located in a box • Place box with scented syrup in a row of boxes containing empty dishes

  4. Data collection • Use new boxes and clean dishes to be certain that scent left by visiting bees is not a factor • Count the bees that enter each box for 10 minutes • Have students repeat the experiment 3 for each scent they want to test

  5. Reporting findings • Plot results for each trial as a bar chart comparing visits to scent laden boxes with visits to unscented boxes • Ask students what the results suggest about their hypothesis • Encourage students to speculate about why honey bees need scent recognition capabilities

  6. Conclusions • Bees can recognize all three scents tested • This test will not quantify scent recognition ability, but bees sense of smell is much more sensitive than the human nose
