These rotations are produced by torques (or moments) about the principal axes. These definitions were analogously applied to spacecraft when the first manned spacecraft were designed in the late 1950s. These axes move with the vehicle and rotate relative to the Earth along with the craft. The axes are alternatively designated as vertical, lateral (or transverse), and longitudinal respectively. Limata's class. Share back what you try too - we're still testing out how these kinds of book and hands-on activity combinations work in action.The position of all three axes, with the right-hand rule for describing the angle of its rotationsĪn aircraft in flight is free to rotate in three dimensions: yaw, nose left or right about an axis running up and down pitch, nose up or down about an axis running from wing to wing and roll, rotation about an axis running from nose to tail.
Try placing a ball on a cup or yogurt container to keep it stable, and use it as a base for a seesaw.Īll of the examples and quotes below are by 2nd grade students in Mr. The story doesn't mention Colin acting as a seesaw, so we imagined our own version of what that might look like to tie in some explorations of balance and stability. How can you transform a paper towel tube into a bridge to transport balls from one place to another? Can your bridge become a ramp? Think about how you can reuse the same materials in different configurations. If you're building a tower, see how tall or how stable you can make your build. ☐ More Ideas: Tape, scissors, drawing materials, and construction paper can help transform everyday objects into characters.ģ. Build a tower, bridge, slide, or seesaw.Ĭonstruct a tower, bridge, slide, or seesaw. ☐ Carrots (building materials): Make your own Colin the carrot using things like cardboard boxes or sheets, poster board, blocks, books, cardboard tubes, cutting boards, container lids, and other everyday materials. Tip: try to find objects that are the same size but different weights. ☐ Peas (things that roll): Collect objects that roll, like different kinds of balls or even limes. To visually tie your builds back to the book, make your own Colin the carrot and find balls or limes to use as peas. Collect - or create - your materials set.
