A.C.'s Backyard

 

What's Happening

A.C.’s Backyard - June 6, 1998

The largest community-built project in Salem’s history resulted in the finest outdoor children’s discovery center in the Northwest. It took 19 days, over 6,000 volunteers, 20 miles of lumber, 2 tons of nails, and unending community support to create the masterpiece of A.C.’s Backyard. Climb the world’s largest erector set tower, play marimbas in the musical ensemble deck, explore the inside of an animal cell, or become the captain of a paddle wheeler. These are just a few of the fantastic adventures you will have in our Outdoor Discovery Center.

 

Erector Set Tower

The most famous and popular of A.C. Gilbert’s inventions was the Erector Set, introduced in 1913. The Erector Set was not only used by children to build toys, but also used by architects and engineers to build models of real structures and machines. In A.C.’s Backyard, you can climb inside our playful Erector Set creation, the Giant Erector Set Tower. At 52 feet, the Tower is the largest of its kind in the world. Three giant slides, including one that is two stories high, and a maze complete the tower.

City of Salem Paddlewheeler

The roads in the late 1800s in Oregon were not efficient. Various wagon trails could be found all over Oregon, but none could transport people and goods as easily as the boats on the Willamette River. The Willamette River served as the main route to transport goods and people into and out of the Willamette Valley. Paddlewheelers were one form of transportation used on the river for passenger travel. The paddlewheeler here is a model of the City of Salem, a beautiful ship that once served the people of Salem.

Sound Science

Talk Boxes

Hunt for the four speaker boxes hidden throughout A.C.'s Backyard. Have a friend stand and one box while you stand at another. Talk back and forth. Do you know why the boxes work? Air passing over your vocal cords causes them to vibrate when you talk. The talk tube captures these vibrations (sound waves) and channels them from one end to the other.

Space Tube Talk

Try This

Can you find all four Talk Boxes? Work with a friend to discover if all the Talk Boxes are connected.

Try This

Both the Space Talk Tube and the Echo Tube change the sounds you make before they reach your ear. How are the sounds of each tube different? What do you think happens to the sound waves in each tube?

 

Musical Ensemble Deck

Try your hand at playing different instruments from around the world, including a variety of marimbas and a South American rainwheel. Get your toes tapping as you rock A.C.’s Backyard with your own global tunes.

Follow the space talk tube on its twisting trail through A.C.’s Backyard. Have a friend stand at one end and you at the other. Try carrying on a conversation. What happens to your voice? Why do you think it sounds so funny?

 

Echo Tube

Shout and clap into this 75 foot tube and experience its amazing sound effects. Sound bounces off the capped end of the tube and is returned to your ear, altered by the rippled interior of the tube and by the distance the sound must travel. How do the sounds change when they are returned to your ear?

Discovery Activities

Try This

Pick out a simple tune such as “Hot Cross Buns” or “Mary Had a Little Lamb” on one of the marimbas. Do some of the marimbas work better for playing these tunes than others? Why do you think this is?

Try This
