Ready to be Zookeeper Zack's helper today? Great! He's just about to make his rounds to give the animals their water. He uses two measuring units: mL (milliliters) and L (liters). Can you figure out the correct unit for each animal? Remember to match the feeding bottles with these four adorable baby animals!

Capacity is how much something can hold. For example, you can find the capacity of a water bottle by reading its label. In this activity, you'll explore two measuring units for capacity. Hurry, these animals are thirsty!
