Eighth graders are able to understand how convex mirrors are used in a microscope. They are able to identify the focus and focal length of a curved mirror and observe virtual images in a convex mirror.

In this lenses worksheet, students will explain how microscopes work by completing 4 short answer questions. Students will compare refracting telescopes with reflecting telescopes by writing the terms given under the correct column. Then...

This well-designed presentation covers many important aspects of the science behind light. In it, pupils view slides that have a lot of the important vocabulary associated with science, slides of famous scientists who made important...

Elementary graders discover the concept of fractional pieces of a whole. They investigate the meanings of fractions in everyday life and why they are used. Pupils divide brownies amongst each other to demonstrate the use of fractions...

For this polygon worksheet, students find the sum of the interior angles of a polygon. They determine the perimeter of equilateral figures, identify concave and convex figures and explore the characteristics of equilateral, equiangular...

Here is a very interesting way of studying triangles and polygons. Pupils work together and use pieces of string to create a variety of shapes. Depending on how many kids are manipulating the string at any one time, the number of...

Students analyze a microscope and study what they do.  In this investigative lesson students study how microscopes were first invented, and how ray diagrams are used in conjunction. 

In this polygons worksheet, 10th graders identify and define both a polygon and a convex polygon and then, they apply two theorems that involve the interior and exterior angles of a convex polygon. First, they find the sum of the...

Students identify different types of polygons. In this geometry lesson, students differentiate between convex and regular shapes. they identify the names of two and three-dimensional objects.
