Vampire Bats

🦇In this updated activity, students explore how vampire bats drink half their body weight in blood in just 20 minutes. Using proportional reasoning and unit conversions (volume, distance, time), they calculate how much liquid a human would drink at the same rate and compare it to the typical daily intake. Students use estimation and real-life context to understand quantities and rates, then evaluate whether the solution makes sense.
