Are you looking for some new and exciting places to take your kids to? Try some of these places: Visit art museums. They offer a variety of activities to excite your kids’ interest. Many offer workshops for making hand-made pieces, travelling exhibits, book signings by children’s favourite writer, and even musical performances and other arts.
    Head to a natural history museum. This is where kids can discover the past from dinosaur models to rock collections and pictures of stars in the sky. Also, ask what kind of workshops and educational programmes are prepared for kids and any special events that are coming up.
    Go to a Youtheater. Look for one in your area offering plays for child and family visitors. Pre-show play shops are conducted by area artists and educators where kids can discover the secret about performing arts. Puppet making and stage make-up are just a couple of the special offerings you might find.
    Try hands-on science. Visit one of the many hands-on science museums around the country. These science play-lands are great fun for kids and grown-ups alike. They’ll keep your child mentally and physically active the whole day through while pushing buttons, experimenting, and building. When everyone is tired, enjoy a fun family science show, commonly found in these museums.
