What better way to learn how to use a microscope than building your own? A lab investigation has scholars use lenses from magnifying glasses and sheets of cork to design their own compound microscopes. They calculate focal length...

In this lenses worksheet, students will review refraction through lenses by reading pairs of statements and circling the correct ones. Then students will read 9 statements and indicate if the statement is referring to a concave lens,...

How do contact lenses work? The simulation allows young scientists to explore focal length and lens type to see how and why contact lenses work. Pupils control the focal length for an eye and a lens, the type of lens, and the distance...

Students learn to differentiate between different types of lenses. In this lens lesson plan, students discover how lenses are different and why a specific lens should be used. Students understand how to find the focal point of a lens....

The concepts of refraction and reflection gel with your physical science class during this colorful exploration. Shining lasers through Petri-dish-shaped gelatin desserts, they will notice how the light travels and bounces off the sides....

Students examine telescope construction. In this telescope lesson, students examine the lenses used in telescopes by exploring with convex and concave lenses.

Learners investigate cohesion, adhesion and surface tension through observations and lab experiments. In this cohesion, adhesion and surface tension lesson plan, students rotate to 5 stations around the room and experiment at each...

In 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...

In this polygons worksheet, 10th graders solve 18 various types of problems related to different forms of polygons. First, they state the number of sides for each convex polygon and then, use the polygon shown to respond to each of 6...

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...

In this lenses activity, 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...

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. 

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 explore vision by experimenting with lenses in equipment. In this optics lesson, students define the different technology that enhances vision such as microscopes, telescopes and cameras. Students experiment with these devices...

Fifth graders view a Powerpoint show about reflecting light. They experiment through a reflection simulation on the internet. Students complete the activity by using mirrors and light to complete send light to a specified spot.

Students discover the different types of mirrors, their properties and some of their applications. They have already been introduced to some of the properties of light and have already experienced some of the different types of mirrors...

In this math worksheet students use the intermediate value theorem to solve two problems. They find parallel lines that will cut a convex shape into two pieces with equal areas. Students repeat this problem with a concave shape. Students...

Fifth graders analyze optical images. in this optical lesson, 5th graders look at how light reflects and refracts. They discuss different types of lenses and how they change the picture that is taken. 

Students are introduced to the art of stone masonry. They identify the seven basic stone tools, demonstrate their use, and compile a list of their cost.

In this optics worksheet, learners read about refraction and reflection, lenses and mirrors, and objects and images. They answer 13 matching questions about light rays, light behavior and types of lenses. They also answer 9 questions...

Fifth graders observe the video, Exploring Light and Color. They access a website to create their own light show. They conduct lab experiments to investigate refraction, reflection,and other light-related topics.

Seventh graders describe and conduct an experiment that identifies the physical properties of light. They explore sources of visible light and an electromagnetic spectrum. Students explain the conversion of one form of energy to another.

Learners investigate the concept of two dimensional polygons. They complete a vocabulary chart with the teacher or in independently. Students are shown various polygons in order to classify them and then asked to draw one of them from...
