These durable plastic holders come in either a one, two, three, or four AA-battery holder.
If you use the one-battery holder, the output will be 1.5 volts. If you use the two-battery holder, the output will be 3 volts. The three-battery holder puts out 4.5 volts and the four-battery holder output will be 6 volts. If necessary, these can be used on a cloudy day to test your Junior Solar Sprint cars. Just hook up the batteries and test your solar vehicle without the Sun!
For small robots, electric cars, and other motorized projects, our Battery Holders will come in handy. Holding either two, three, or four AA batteries, they have their own switches, so the motorized object doesn’t need one. And, they come with leads and a removable cover.
When used with your Construction Caddy II and Perf Insert, this Accu-Fixtures Set is the best way to snap your project in place! The small plastic pieces come in round and angular shapes to help your project stay in place while you make the finishing touches.
You’ll be impressed at how strong structures are when you use these tools. Each set includes six 45º/45º/90º Accu-Angles, two 30º/60º/90º Accu-Angles, and six Accu-Cams. Cams require Perf Insert, sold separately.
Whether your sights are on design, strength, history, symmetry, or construction techniques, this guide helps focus your efforts on using this popular structures activity. In the process, students learn about the strength of materials, types of joints, design concepts, lamination, and efficiency.
The Balsa Bridges Teacher’s Guide contains NGSS, CCSSM, NCTM, NSTA, and ITEEA standards addressed; teacher and student instructions for a variety of math, science, and technology activities; pretests and posttests; resource pages; and puzzles. Contains separate activities for middle school and high school students.
Equipment and materials needed to complete guide activities include the Pitsco Balsa Bridges – Getting Started Package, weights, 500-gram and 200-gram spring scales, clamps, ruler, safety glasses, protractor, digital scale with 33-pound minimum capacity, and standard classroom tools and materials. Note: This list is for all activities; individual activities don’t require all listed materials.
A strong truss makes a strong bridge or roof. So testing a truss design before building an entire model bridge or roof makes sense – and now you can do that with the Balsa Truss Tester. It works with either a hanging weight or on the Structures Testing Instrument (with the Balsa Truss Tester Adapter), sold separately.
Designed specifically for trusses made from 1/8" balsa wood, this tester adjusts for trusses up to 4" tall and 12" wide. It has two different load blocks: one adjusts to four different angles (15°, 20°, 25°, and 30°) for triangular trusses, and the other is square for flat-topped trusses.
Made of colored acrylic, the tester's clear acrylic shield keeps trusses securely in place for testing while offering protection from splintering wood. Comes assembled.
This adapter enables you to use the Balsa Truss Tester with the Structures Testing Instrument.
