First graders survey different classrooms to determine types of products students would like to see sold at school, and create graphs based on survey results.

Students calculate the area of different polygons. In this geometry lesson, students find the area for trapezoids, rhombuses and kites.

Students explore photovoltaic systems. In this alternative energy lesson, students calculate solar panel efficiency and convert devices to solar energy using photovoltaic cells.

Students trace the route of the historical event and measure the distance over which the people involved journeyed. A data sheet be constructed outlining the location of events, and the speed with which the journey occurred.

Ninth graders demonstrate application of area, surface, and volume. They apply formulas to a model of the classroom so they can determine the volume and surface area of the classroom.

Students determine the missing vertices of quadrilaterals. In this rectangles and trapezoids instructional activity, students examine the characteristics of quadrilaterals. They identify the missing vertices of a quadrilateral on a...

Tenth graders experiment with gravity and air pressure. In this geometry lesson, 10th graders build their own kits and fly it. They investigate the questions: what keeps a kite in the air and what are some important factors when flying a...

Young scholars differentiate between inductive and deductive reasoning. In this geometry lesson, students identify congruent figures and examine logos for congruency.

Students work in groups to show understanding of the relationship between fractions, decimals, percentages, and the application of ratios and proportions. In this decimals, fractions, and percents lesson, students use real life consumer...

Students find the cost of an outfit. In this percentages instructional activity, students look at ads, pick out an outfit, and find the sale price. They create a commercial and complete 4 included worksheets. 

Students explore the concept of stem and leaf plots.  In this stem and leaf plots lesson, students plot the 50 US states' capitals on a stem and leaf plot according to the first letter of each state.  Students compare...

Students use the Nspire software to graph. In this algebra lesson plan, students graph quadratic equations using technology and graphs. They identify the maximum and minimum of each graph.

Here is a new twist on teaching the associative property of multiplication. The author of this presentation makes an analogy between the associative property and a couple getting married. The numbers, like people, are separate, but when...

Young scholars discuss elements of word problems: key words, data, computation clues, and unnecessary information and use the four steps of problem solving to find a solution and check for reasonableness.

Challenge your class to use their understanding of the engineering design process to design and build a small-scale, off-road prototype for an assistive technology device. Teams select materials to build their scale models, and, using...

Magnetic resonance imaging, just how safe is it? The introduction to unit study of magnetic resonance imaging technology presents the grand challenge questions of how an MRI machine works, the risks involved, the physics involved,...

According to the Farmers' Almanac, the weather will be nice today. Class members examine how weather forecasting plays a part in their lives with a resource that provides information on the history of forecasting, from using cloud...

Young scientists race from Earth to Mars and back, trying to complete mission objectives while avoiding radiation in this game for 2-4 players. To identify the winner, players must graph their mission points and radiation points at the...

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.

A little too much strain could cause a lot of stress. Groups conduct a strength test on clay. Using books as weights, pupils measure the compression of clay columns and calculate the associated strain and stress. Teams record their...

Osteoporosis and family — notice the connection between the two. Pairs develop a brochure to educate the public about osteoporosis in the last portion of the six-part series. The teams draw on the information learned throughout the...

Teams use the design process to design, build, and test a model levee to protect the town from a wall of water. A handout provides a price list for the materials learners can use to build their levee within a budget.

Here is an activity that merges technology with life skills as individuals use Google Earth to explore the differences between coordinate systems and map projections. The self-guided learning exercise is the fourth segment in a nine-part...

Help your class make a connection between salt water and nanoscience. In the introductory lesson of a seven-part unit, the class explores why salt water helps a sore throat feel better. Pupils conduct preliminary research about the...
