Question: Something happens to produce a sound. The sound travels in waves. The sound waves hit an object. The object absorbs some of the sound waves. Some of the sound waves bounce off of the object. The reflected sound waves can be heard, though they have slightly different properties than the original sound. The sound continues to bounce off of things and produce echoes until it is totally absorbed or dissipated. 

Answer: How do echoes occur?


Question: Bees find a place for the hive, such as a rock crevice or tree branch. Bees gather nectar from flowers. The bees evaporate the nectar by passing it back and forth to each other. The evaporation turns the nectar into sugary honey. The bees chew the honey until it turns into moldable wax. The bees mold the wax into hexagonal (six sided) cylinders. Thousands of these hexagonal cylinders put together form the hive.
