Watts, Jo; Bull, Glen, 2024, "Mechanical Wave Machine", https://doi.org/10.18130/V3/LSNBFW, University of Virginia Dataverse, V2
The Mechanical Wave Machine is designed to enable students to explore and understand the way in which the motion of a series of cams can simulate the motion of a wave. |
Watts, Jo, 2023, "2D Cam Explorer", https://doi.org/10.18130/V3/7GJGNC, University of Virginia Dataverse, V4
The 2D Cam Explorer is designed to be used with the mechanical wave machine. The 2D Cam Explorer represents a single segment consisting of one cam from the wave machine. After a classroom demonstration of the wave machine to illustrate wave properties, the 2D Cam Explorer can be used to enable individual students to explore the principles underlyin... |
Haas, J. Patrick, 2023, "NASA Pinhole Projector", https://doi.org/10.18130/V3/DKUZB0, University of Virginia Dataverse, V2
These 3D printable maps are shaped like the contiguous United States of America and show the paths of solar eclipses traversing the country. Each object contains a pinhole in the center that will provide safe and engaging viewing of changing solar images during stages of a solar eclipse. Sun shining through the pinhole (for example over a shoulder... |
Baumann, Kimberly; Sondej, Elizabeth, 2023, "Minute Minis", https://doi.org/10.18130/V3/ZGC6UV, University of Virginia Dataverse, V8
Minute Minis are essentially relabeled fraction circles: the whole is labeled ‘1 hour,’ the halves are each labeled ’30 min,’ the fourths are labeled ’15 minutes,’ and the twelfths are labeled ‘5 min.’ The designers of Minute Minis wanted to design a tool that would alleviate the anxiety that children often experience when they learn about fraction... |
Davidson, Jessica; Mateo, Mayrobi, 2023, "No Más Caídas", https://doi.org/10.18130/V3/IFKSBY, University of Virginia Dataverse, V5
No Más Caídas is a manipulative that helps children learn to count by forming groups of fives and tens (i.e., by subitizing), generalize strategies for composing and decomposing numbers, and develop a sense of the nested nature of numbers. No Más Caídas is Spanish for No More Falls. The design was inspired by games played in the Dominican Republic,... |
Kaupp, Lauren; Philippoff, Joanna; Seraphin, Kanesa; Lurie, Matthew, 2023, "Wave Prints", https://doi.org/10.18130/V3/ILBUSG, University of Virginia Dataverse, V4
This activity, first published by the National Science Teaching Association (NSTA), uses a wave tank to create a standing wave and capture its physical profile in the form of a wave print. Students create a standing wave in a wave tank and record the profile of the wave by making a print of it. This is accomplished by dipping an absorbent sheet of... |
Garofalo, Joe, 2023, "Solenoid", https://doi.org/10.18130/V3/QKHVG8, University of Virginia Dataverse, V1
The Make to Learn solenoid can be used to explore principles of electricity and magnetism. This solenoid can be used with the Linear Motor in the Engineering Section. |
Watts, Jo; Bull, Glen, 2023, "3D Cam Explorer", https://doi.org/10.18130/V3/L63YMY, University of Virginia Dataverse, V3
This model is designed to enable students to explore and understand the way in which the motion of a series of cams in a mechanical wave machine can simulate the motion of a wave. A cam translates rotary motion into linear motion. A circular cam reproduces the circular motion of a particle of water in an ocean wave. The mechanical motion of the cam... |
Siegel, Lauren, 2023, "Trigonometry Angle Formulas", https://doi.org/10.18130/V3/LJ9PB2, University of Virginia Dataverse, V5
Making sense of trigonometric identities; To help students derive and thus make sense of the trig identities, sin (a + b) and cos (a + b). The Trigonometry Angle Formulas comprises four right-angled triangles of different dimensions that are joined to form a rectangle. The inscribed triangle is a right angle that touches all four sides. By labeling... |
Bull, Glen; Watts, Jo, 2023, "Linear Motor", https://doi.org/10.18130/V3/98YZHR, University of Virginia Dataverse, V2
The Make to Learn Linear Motor can be used to explore principles of electricity and magnetism while providing historical context. The linear motor is a functioning electric motor constructed from a coil of wire and a permanent magnet. The Make to Learn Linear Motor is inspired by the Charles Page Motor patented in 1852. This early electric motor pr... |
