Math rocks! Cavern design teams determine the rankings of rock types based upon desirability points. The points are connected to the properties of the rocks and their usefulness in building a cavern. 

What do logarithms have to do with bone density? Scholars learn that the equation for bone density includes logarithms. The majority of the third lesson of seven is devoted to logarithms and their properties.

Time is growing short. Teams work together to identify physical properties of rocks in order to determine the properties that would best suit their cavern shelter design.

Nothing says organization quite like a table. The third lesson in a six-part Mixtures and Solutions unit teaches young scientists about elements and the periodic table. They learn how the periodic table is organized and about the...

Now it becomes crystal clear why the unit is called Mixtures and Solutions. The fifth installment of a six-part unit explores mixtures and solutions. After viewing a demonstration on mixing pebbles with water, salt with water, and...

Students research additional information about questions on their worksheet. In this energy activity, students develop visual aids of their proposed solution to the problem. They present their work in class.

Discover how to analyze architecture from a geometric standpoint. The fourth installment of an 11-part unit on architecture first provides a presentation on axis, balance, basic form, formal, pattern, proportion, symmetry, and tripartite...

Bend it, but don't break it. Groups investigate the strength of different materials. Using a procedure in the seventh segment of a 22-part series on aviation, pupils determine how far a rod will bend. They determine the strength-to-mass...

 The class must determine the magnetic properties of different materials, including aluminum and steel by sorting through materials using a magnet. Groups make a prediction on whether a material is magnetic and then perform...

Model an oil spill cleanup. An engaging engineering lesson has groups using aerogels to simulate an oil spill cleanup (vegetable oil in water). Along the way, they learn about nanotechnology and hydrophilia/hydrophobia.

Seventh graders review graphing procedures and practice locating points using x,y coordinates. Students calculate the areas of the top and bottom surfaces of the airfoil. They construct a test model of the airfoil.

An outstanding lesson on triangles awaits your math scholars. Learners focus on the triangle, which is the strongest of all polygons. They see the role that triangles play in the design of buildings, and learn about triangle...

Can you beat the odds of cancer? In the first installment of a seven-part series, future biomedical engineers consider how to detect and diagnose cancer. An article on biosensors provides useful information toward this goal.

Students explore the properties of light. In this light lesson, students investigate visible light by viewing a website, examining an electromagnetic spectrum chart, and observing light demonstrations. Students write about their...

Elasticity and viscosity. Help your class understand the similarities and differences with an introduction to viscous fluids. After describing four types of fluid behaviors: shear thinning, shear thickening, Bringham plastic,...

Middle and high schoolers explore the concepts of architectural rigidity. They analyze a variety of polygons, and explain why some shapes add more strength to structures than others. The PBS video, "Building Big," is utilized in this plan.

Prepare young scholars for life in the twenty-first century with this introduction to computer coding formatted as a fun problem solving game, this resource is a great way to develop children's sequential thinking...

Students identify the different types of fractals. In this geometry lesson plan, students use math to analyze different biological phenomena. They collect data from the experiments and construct graphs.

Groups use a marble to determine the viscosity of household fluids. The procedure calls for pupils to measure the amount of time it takes a marble to fall a specified distance in the fluids. Using unit conversions and algebra, the teams...

Too much material will weigh you down. The sixth segment in a series of 22 highlights how weight affects a plane. Pupils learn that engineers take the properties of materials, including weight, when designing something. 

Your pupils can build their own electromagnet — awesome! The culminating activity in an eight-part series challenges groups to design and build their own electromagnet. The goal of the activity is to build a magnet capable of picking up...

What effect makes children's shoes light up? Answer: Piezoelectric effect. Here is a PowerPoint presentation that describes piezoelectric materials as being able to convert mechanical energy to electrical energy. Individuals learn how...

Learners explore multiplication concepts.  In this multiplication instructional activity, students define "array" and draw several arrays to represent multiplication number sentences.  Learners construct arrays on the computer...

The design challenge: develop a method to separate steel from aluminum. The first lesson plan in an eight-part series introduces the class to the grand challenge of ciming up with a method to streamline a sorting process at a...
