Math and Science

We just started a new math unit "Patterns and Relations and Solving Equations".  Some students have run out of math notebooks.  Getting setup with a new notebook is for homework.

In science students are to read pages 290-292 and complete the following in their notebooks,

1.Indicate whether each joint is rigid (R) or mobile (M).

            (a) door hinge

            (b) nut and bolt holding a wheel on a car

            (c) ball and socket in your shoulder

            (d) joint where the leg of a chair is fastened to the seat

            (e) ball at the end of a ballpoint pen

            (f) joint created where the handle is fastened to a pencil sharpener

            (g) joint created where the handlebars of a bicycle are fastened to the frame

            (h) joint created where the pages are fastened in a notebook

            (i) joint where a computer monitor is fastened to its base

2.     Complete the table below to identify properties and uses of rigid joints. In the last column, you can describe how a joint works using words or a diagram. Give the table a title.
