Building balsa wood bridges as a part of a unit on statics, structures, forces, or construction trades is used by teachers to make the learning environment hands-on and to give students a real-world example of material covered in class. The building of balsa-wood bridges is often used as an educational technology. It may be accompanied by a ...
A Jacob's ladder (also magic tablets, Chinese blocks, and klick-klack toy [1]) is a folk toy consisting of blocks of wood held together by strings or ribbons. When the ladder is held at one end, blocks appear to cascade down the strings. This effect is a visual illusion which is the result of one
Alphabet blocks. The identification of specific toys as having an explicitly educational purpose dates to the 1700s. [11] In 1693, in Some Thoughts Concerning Education, liberal philosopher John Locke asserted that educational toys could enhance children's enjoyment of learning their letters: "There may be dice and play-things, with the letters on them to teach children the alphabet by playing ...
The first nine blocks in the solution to the single-wide block-stacking problem with the overhangs indicated. In statics, the block-stacking problem (sometimes known as The Leaning Tower of Lire (Johnson 1955), also the book-stacking problem, or a number of other similar terms) is a puzzle concerning the stacking of blocks at the edge of a table.
LignoSat was developed by Kyoto University and logging firm Sumitomo Forestry as a demonstration of using wood for space exploration uses. [4] The satellite is named after the Latin word for "wood" which is "Ligno". LignoSat is made of wood from honoki, a magnolia tree native in Japan. Wood from the tree is customarily used for sword sheaths.
Starting with blocks of wood and rubber bands, Rubik set out to create a structure that would allow the individual pieces to move without the whole structure falling apart. Rubik originally used wood for the block because of the convenience of a workshop at the university and because he viewed wood as a simple material to work with that did not ...
In a Klotski puzzle, the largest block must be moved to the bottom middle location so that it can be slid over the border, without any of the other blocks being removed in this way. Klotski (from Polish: klocki, lit. 'wooden blocks') is a sliding block puzzle thought to have originated in the early 20th century. The name may refer to a specific ...
Cinder blocks are placed on the board and then smashed with a sledgehammer. Despite the seemingly unavoidable force, the volunteer is not harmed: the force from the blow is spread among the thousands of nails, resulting in reduced pressure; [4] the breaking of the blocks also dissipates much of the energy from the hammer. This demonstration of ...
