Catenary Arch Kit
A great hands-on lab for physical science. This set of hardwood blocks is precision-cut in
the shape of a catenary arch. It needs no support because it is the ideal shape to hold
its own weight. The forces acting on the arch cause it to take the shape of a curve naturally.
Set of 13, precision-cut hardwood blocks (each approximately 2" L x 1 /2"-1" thick);
full-size template; and instructions. Grade 3 to adult. Sh. wt. 0.51 kgs.

Catapult
Boost learning trajectory with an authentic catapult.
Build one with planks, a little glue, and the help of
easy, step-by-step instructions, then let the fun begin!
Conduct experiments involving how far the arm is
pulled back, the height of the flight deck, or the distance
two different objects can travel when launch
conditions are identical. No tools required! Includes
pre-drilled pine planks, wood glue, cotton rope,
ruler, rubber bands, cup, three beanbag projectiles,
target mat, fasteners, and instructions. Grade
1 and up. Sh. wt. 1.75 lbs.

Trebuchet Kit
Trebuchet kit provides a fun and exciting environment for studying energy conversion,
levers, trajectories, ratios, rotational motion, inertia, forces, and more! Powered by gravitational
potential energy, this easy to assemble kit provides hands-on, practical building
experience while fueling the imagination with history and science. Investigate how
projectile range is altered by changing such variables as weight, weight position, sling
length, pivot point, and projectile mass. Each kit is supplied with assembly instructions
and internet resource materials that provide investigations into the theory of operation,
mathematical modeling, history, and more! One-year warranty. Grades 5-12. 1 /2" x 4" x 15".
Sh. wt. 0.50 lbs.

Model Bridge Classroom Pack
This popular activity is an exercise in creative problem solving. Middle school and high
school students will be challenged to design and construct their own wooden bridges,
and enjoy the thrill of destructive testing. They will then calculate their bridge’s efficiency
to determine the best design. Each classroom pack provides 24 students with the
necessary wood (15 pieces per student), adhesive, and competition design parameters
to conduct a competitive lab activity. Choose either 3 /32" x 3 /32" x 24" basswood or 1 /8"
x 1 /8" x 24" balsa wood. Basswood is stronger and has a more consistent density, while
balsa is lighter and easier to cut. Each classroom pack also includes a booklet titled
Teaching with Model Bridge Building Program. Sh. wt. 2.24 kgs.
