Discover the relationship between tangent lines and the tangent function. Class members develop the idea of the tangent function using the unit circle. They create tables of values and explore the domain, range, and end behavior of...

Practice recognizing types of additive angles with a worksheet in which pupils review adjacent, interior and exterior, complementary, and supplementary angles and use a diagram to give examples of them. Be aware that the diagram involves...

Young English language learners trace color vocabulary words on the lines and match it to the correct illustration. A visual and direct approach to developing color vocabulary! 

How do the moon, sun, and Earth line up to create eclipses? Why do the seasons change throughout a year? The answers to these questions are explained through this series of slides. This apt presentation outlines information using bullet...

Students compare rates to altitude. They conduct a class discussion about the results.

Students create their own "weather" map using data from x-ray sources. They analyze and discuss why it is important to organize data in a fashion in which is easy to read. They compare and contrast different x-ray sources using a stellar...

Learners observe and demonstrate a variety of basic geometric constructions using the Triman Safety Compass. Using the compass, they draw circles, bisect a line segment, construct an angle, bisect an angle, copy an angle, and create...

In this sun's magnetic field lines learning exercise, students use a photograph taken by the Hinode Satellite that shows the complex magnetic structure of the sun over a sunspot. Student predict the magnetic field lines and draw them on...

Young scholars examine and explore various line, color, and movement elements in artwork. They view and discuss examples of abstract artwork, and create their own original abstract design that tells the story of a road trip.

Fifth graders practice the concepts related to finding and identifying different angles. There are examples included in the lesson that are useful for the teacher to deliver the lesson.

Geometry is full of shapes, figures, and corresponding things here and there. The guide shares all of the key pieces of geometric information in a nicely color-coded and labeled sheet. 

Did you know that Marie Curie's papers, as well as her cookbook, are radioactive and stored in lead-lined boxes? Did you know that Nikola Tesla developed a death ray? Famous scientists and inventors are the subjects featured in a series...

In this exploring angles learning exercise, 10th graders solve 12 various types of problems that are related to measuring various angles. First, they name the vertex of an angle and determine whether it appears to be acute, obtuse,...

Tenth graders investigate parallel lines and the angles formed when cut by a transversal. In this geometry activity, 10th graders construct perpendicular lines and discuss midpoint, segments and perpendicular bisectors. They relate...

Students explore Geometry with Twizzlers Candy, pipe cleaners, paper, pencils, and protractors. They manipulate these items to create different angles introduced by the teacher.

Study concave and convex mirrors with an in-depth slideshow presentation. Slides contain term definitions as well as labeled diagrams.

Life is only a reflection of what we allow ourselves to see. The lesson includes three experiments on light reflection, light refraction, projection, lenses, and optical systems. Each experiment builds off the ones before and...

Knowing the basics of drafting allows individuals to create drawings that show all the views and measurements necessary to allow others to visualize the original object. Pupils gain experience by drawing three orthographic views of...

Acute angles, nets, and vertices are only a few terms that a set of flash cards includes. Among the 108 cards, two types are available; word cards printed in bold-faced lettering, and corresponding definition cards equipped with an...

Parallel structure is tricky, even for many adults! Give your class extra practice with this two-page resource. For each of 16 sentences, they rewrite it using parallel structure. Do an example or two with them to give them confidence...

Students practice their drawing skills using a variety of stories as sources for their inspiration. Crayons and pencils are utilized to model different line widths, textures, and shapes.

Students work with a real optical spectrum of a gamma ray burst afterglow taken at the Keck Observatory. They measure the shifts of spectral lines, deduce the velocity of the astronomical object, and then use Hubble's Law to get its...

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...

Fifth graders explore geometric building blocks in the real world in order to describe the characteristics and relationships of points, lines, line segments, rays, and planes. This is the first lesson plan in a series of lessons in...
