Your geometry learners will discover and show the construction of the circumcenter of a triangle. Guided by the steps in the activity, they construct perpendicular bisectors of each side that have a point of concurrency called the...

Given specific materials, scholars follow a set of instructions to build and calibrate their very own spectroscopes. After construction, they test the scope for accuracy and make modifications where necessary.

You say that perpendicular bisectors intersect at a point? I concur! Learners investigate points of concurrencies, specifically, circumcenters and incenters, by constructing perpendicular and angle bisectors of various triangles.

Launch your class on an exploration of the solar system. Learners construct solar system models to scale and get a better understanding of our place in the vast void of space. This is a great way for them to cement their understanding of...

Students construct a fault model using the Fault Model Sheet imbedded in this plan. They create a 3 dimensional model of the Earth, and use dashed lines to illustrate where the fault lies. A discussion of faults follows the completion of...

Students investigate how rocket liftoff demonstrates Newton's Laws of Motion. They participate in a class discussion, and construct a rocket powered by the pressure generated from an antacid tablet reacting with water.

An engaging lesson which has elementary learners measure weight to the nearest pound and construct and interpret a bar graph! They measure length using non-standard units and determine area using square tiles. Pupils round their birth...

Junior ecologists relate how food chains and food webs route matter and energy through an ecosystem. They trace feeding levels of a food chain or food web through a pyramid of energy. As a reinforcement activity, learners construct three...

Young scholars create personalized place mats as they learn about initial sounds. Using construction paper, they stamp their names using letter stamps. Scholars examine print resources and cut out pictures with the same initial sound as...

Each group talks about how to test unknown liquids based on their findings in the previous experiment. In this second of four activities, they test unknowns on wax paper, newspaper, and construction paper. As a stand-alone, this lesson...

Japan is one of only a handful of countries that constructs buildings that are almost earthquake proof. The 13th lesson in the 20-part series challenges scholars to build structures to test against earthquakes. With limited materials and...

Looking for the best inclined plane for the job? Groups calculate the theoretical mechanical advantage for four different inclined planes. They determine the actual mechanical advantage by measuring the amount of force needed for the...

Why are only four colors needed to color webs from regular pentagons, not five? An assessment task requires young mathematicians to first construct regular pentagons using a compass and straightedge, then has them consider a shape...

Are you searching for a purpose for geometric constructions? Use an engaging approach to explore dilations. Scholars create dilations using a construction method of their choice. As they build their constructed dilation, they...

Playing with mathematics can invoke curiosity and excitement. As pupils construct triangles with given criteria, they determine the necessary requirements to support similarity. After determining the criteria, they practice...

A diameter is the longest chord possible, but that's not the only relationship between chords and diameters! Young geometry pupils construct perpendicular bisectors of chords to develop a conjecture about the relationships between chords...

Maximizing resources is essential to productivity. Class members complete an activity to show how math can help in the process. Using a piece of construction paper, learners construct a box with the maximum volume. Ultimately, they...

First graders identify monarch butterflies and study their life cycles. They order the stages of the life cycle and create a monarch butterfly of construction paper. This well-designed lesson should be easy to implement in your classroom.

Here is another in a series of fantastic art lessons from this source. This one has young artists create a sarcophagus-style clay box! This lesson would be ideal to utilzie during a study of the ancient Egyptians. One note of caution:...

Learners construct a model of an electromagnetic spectrum using play-doh and string. They use exponents and plot the radio/microwave, infrared, and visible bandwidths of the spectrum.

Young artists construct and create a journal. They develop the book using black construction paper, acrylic paint, glue, and tape. The art lessons from this source are among the best I've seen. The products produced by the students are...

Students identify the food groups and agricultural sources of pizza ingredients. They construct a construction paper pizza, identify the crops grown for pizza ingredients, and make and eat English muffin pizzas.

Sunsets and shadows are lovely subjects for creative projects. Kids take a good look at images of sunsets, then use paint and construction paper to create a silhouetted sunset image. Tip: This project is a great way to illustrate a poem...

Students construct models that demonstrate potential sources of contamination. Students select one type of contamination model (septic system, sinkhole, landfill, disposal lagoon, leaky barrels, oil spill, agricultural contamination) to...
