At the halfway mark for summer vacation, scholarly children (or parents) might start to worry about summer homework, such as research projects or picture diaries that have yet to be finished.

Before you write a diary about playing video games every day, check out the Marunouchi Kids' Festa, which will run for three days next week. The event will offer various activities for children, some of which are quite educational while others are just plain fun.

On Aug. 17, rescuers from the Fire and Disaster Management Agency will present examples of how they train and, as a bonus, will send a musical troupe to entertain kids, too. Yasuaki Nohguchi will perform a scientific experiment to demonstrate how drawn-out earthquakes break down high buildings.

On Aug. 18, dogs working for the Metropolitan Police Department will be on show, as officers explain how they train the canines to follow instructions and find illegal drugs, pistols and bombs. On the same day, B.B. Mo-Franck, a well-known percussionist who starred in the musical "The Lion King," will play djembe and dance with visitors.

On Aug. 19, children can learn how to practice safe bicycling. Elmo and his friends from Sesame Street will also perform a crime prevention show.

These events are merely a few of the more than 130 activities the event offers. Overall, a great chance to find the topic for your summer homework — in a fun way.

"Marunouchi Kids' Festa" runs from Aug. 17 to 19. Some events require prior registration. For more information, visit www.t-i-forum.co.jp/kids
