Rating
0.0 stars

After reviewing types of angles and how to measure angles using a protractor, students will see how many triangles they can construct using an 18-foot beam.  Through this activity, students will discover the conditions that must be met to construct a triangle.  For example, the sum of the lengths of two sides of a triangle must be greater than the longest side of the triangle.  They will also discover that the sum of the angles of a triangle is always 180 degrees.

In this lesson plan, students will use protractors to measure angles and draw angles of a specific measure. Students will also use an angle wheel as a way to measure the degrees of an angle. Finally students will study artistic prints and find an angle within the picture to measure and then discuss why they used the measure in the artwork.

Students use simple materials to design an open spectrograph so they can calculate the angle light is bent when it passes through a holographic diffraction grating. A holographic diffraction grating acts like a prism, showing the visual components of light. After finding the desired angles, students use what they have learned to design their own spectrograph enclosure.
