Wegener’s continental drift hypothesis: The theory of continental drift simply stated that continents drifted from one location to another over time. Wegener noticed that the coasts of South America and Africa seemed to fit together like a puzzle. Upon further investigation he noticed the following clues that he used to support his hypothesis.

The upper guard is the most popular choice, however, you may opt for a(Continue reading) No, they don’t use the same for all puzzles although some are the same. The dies for cutting jigsaw puzzles are expensive and can be used for more than one puzzle. In many cases you can interchange, but it isn’t always the case.

If you choose to step on the tile underneath the purple switch, you’ll have two options. Head to the tile closest to the original spawn point, then onto the light blue switch. The rest of the way through is linear, taking you back through the purple switch and onto the goal.

In 1912, Alfred Wegener proposed a theory that the continents had once been joined, and over time had drifted apart.

• Groups label the continents or land mass on each piece. The students then color each fossil type and the Key to Wegener’s Evidence sheet. Then cut out the land masses from the evidence sheets. • Have the students arrange the puzzle pieces using the Key to Wegener’s Evidence to support their arrangement.

Wegener reluctantly agreed. After many delays due to severe weather, Wegener and 14 others set out for the winter station in September of 1930 with 15 sledges and 4,000 pounds of supplies.

Name: Date: WEGENER’S PUZZLING CONTINENTS Overview: Although Alfred Wegener was not the first to suggest that continents have moved about the Earth, his presentation of carefully compiled evidence for continental drift inspired decades of scientific debate.

Ribbon-cut jigsaw puzzles are the most common type. Ribbon-cut pieces are relatively square with gaps or tabs on each of the four sides. There are only a few puzzle piece shapes, and they fit together in a simple, grid-like pattern.

Using numerous figural templates, the cutters focused on placing and cutting figurals within color sections as they cut each section piece by piece. The earliest puzzles tended to be less interlocking and more angular, but the cutters began inserting knobs between non-figural pieces within color line cut sections in the 1910s.

In her personal puzzle-solving experience, “a 500 piece jigsaw is small enough to be spread out completely on a table so that all the pieces can be viewed at the same time,” McLeod shares. “This makes it easy to simply pick out pieces to be assembled, without sorting; usually, each piece contains enough details to uniquely identify it.”
