Middle-schoolers still enjoy playing with bubbles! In this series of eight laboratory activities, science learners explore convex and concave surfaces, angles, gas laws, buoyancy, density and more! 

Did you know some retailers use curved mirrors in their fitting rooms to make customers look thinner? Pupils view themselves in convex and concave mirrors to understand the difference. The resource includes big ideas for multiple age...

Explore optics using an inquiry-based experimental approach! Young scholars use a set of materials to design and build a unit capable of focusing a beam of light. They experiment with different lenses to determine the best approach to...

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

Third graders utilize the scientific method to explain light and optics in this five lessons unit. Through experimentation and discussion, 3rd graders canvass the concepts of light traveling, reflection and refraction.

Your class might be surprised to learn that mirrors have been around since the first century AD! Young scientists explore reflection and refraction of light through a series of challenges. They use this knowledge to design their own...

Students define the importance of the properties of quadrilaterals. In this quadrilaterals lesson, students identify the general properties of and compare and contrast the properties of convex and concave quadrilaterals. Students also...

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...

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...

Young scholars view images in a spherical mirror and interpret the path of light. In this physics lesson, students view a large spherical mirror demonstrated by the instructor. They use shiny serving spoons to investigate the path...

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....

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...

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...

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 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.

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.

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...

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...
