For 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,...

Pupils examine telescope construction. In this telescope instructional activity, students examine the lenses used in telescopes by exploring with convex and concave lenses.

With a Florence flask or fishbowl, make a double convex lens and use it to examine an image. Because of the refraction, the image will be inverted. A simple explanation is provided here for you to share with your class as they...

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...

How can a magnifying glass or reading glasses make things appear larger? Scholars simulate moving a lens closer or farther from an object to observe the resulting image. They also alter the lens focal length. The simulation shows the...

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...

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...

Polygons — it's all about the angles. Groups work with dynamic geometry software to find the sum of the measures of the angles of various polygons. After finding the information for several polygons, the groups generate a formula that...

Illuminated physics stars show what they know about light by taking this exam. They match several related vocabulary terms to descriptions and answer multiple choice questions about the characteristics of light, magnification, and...

Learners analyze convex polyhedra through hands on methods. In this geometrical shapes lesson, students construct paper models of convex polyhedra and identify the different properties including the number of sides, faces and edges.

Don't worry, optics is a light topic! The presentation covers reflection, refraction, fiber optics, mirages, prisms, rainbows, dispersion, mirrors, lenses, telescopes, diffraction, the human eye, and much, much more. Presentation is...

Explore the connection of light, reflection, and mirrors. A comprehensive lesson introduces the basics of light in relation to reflection and mirrors. After an explanation of the vocabulary, the presentation shows how to create ray...

In 2017, more than 15,000 scholars earned college credit based on their AP Physics 2 exam covering lenses, energy, and more. The College Board released the free-response questions, sample answers, and scoring guidelines from that exact...

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....

Students draw triangles and explore the classification of each using the measures of interior angles and lengths of sides. They investigate the sum of the interior angles of various triangles and conjecture and prove the theorem: The...

Students explore light, and how it travels in straight path, recognize that light-sensitive chemical processes can be used to create images using light as catalyst, discover that light can be refracted by convex lens to focus camera,...

In this optics worksheet, students 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...

Life science learners need to be able to use a microscope. With this comprehensive resource, they first experience how lenses and magnification work, and then get familiar with using a compound microscope. Tremendous background...

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 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.

High schoolers derive a formula for the interior degrees in any convex polygon. In this geometric figure activity, students determine the shapes of various polygons and the number of triangles formed. They use this information to derive...

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...

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

In this geometry worksheet, 4th graders find 13 words in a word search puzzle. They find words such as convex, prism, cylindrical, and cone which are placed diagonally, vertically, or horizontally in the puzzle.
