Students explore the different arrangement of air molecules in high and low air pressure masses. They compare the temperature of high and low pressure masses and discover how a barometer works.

Using their knowledge of right triangles, pupils find out how far a ship is from a light house. Class members determine how far around the world a ship would be sailing at a constant speed.

Students draw a chart (included in the lesson) to use with their investigation. They review terminology of triangles and receive toothpicks to use in the lesson. Beginning with three toothpicks, students form a triangle. They complete...

Bring math and reading informational text together with a reading comprehension lesson. After kids read about isosceles, scalene, and equilateral triangles, they answer five comprehension questions to demonstrate how they can use context...

Fold, fold, and fold some more. In the first installment of a 35-part module, young mathematicians fold a piece of paper in half until it can not be folded any more. They use the results of this activity to develop functions for the area...

Parallel lines seem so right for each other. It's too bad they'll never, ever meet. Learners use tracing paper to discover relationships among angles formed by two parallel lines cut by a transversal. They apply this information to find...

Young mathematicians use the Visual Thesaurus to define mean, median, and mode. In this mean, median and mode lesson, learners use online sources to find the definitions of mean, median, and mode before applying the concepts to a class...

Students explore satellite data and graphing. In this weather data analysis math and science lesson, students analyze NASA satellite data to draw conclusions about geographical areas where precipitation might have happened. Students...

Join Zoe as she calculates the average number of points RJ scored in his basketball games. This step-by-step presentation clearly models the procedure for finding the mean of a data set, including examples with both whole number and...

Explore four web-based interactive sites to develop a baseline understanding of statistics. Learners play a series of penny basketball games and collect data regarding their shooting statistics. Groups decide who is the "top" penny...

There are four activities in this extensive lesson covering the identity matrix and scaling, the linear representation of translations, the linear representation of rotations, and reflections. In small groups, they use the Cabri II...

Immediately capture the attention of your class with the smell of freshly popped popcorn in the sixth lesson of this series on the needs of living things. Young scientists first use their senses to make and record observations of...

Life science learners construct lung-o-meters from gallon-sized milk jugs and then measure their lung capacities. For older students, have them graph the vital lung capacities of each person in the class. Cross-curricular pieces are...

Referring to the periodic table of elements, nuclear physics learners determine the resulting elements of alpha and beta decay. Answers are given in atomic notation, showing the atomic symbol, mass, atomic number, and emission particles....

With rising oil prices and increasing concerns over global warming, the pressure is on for engineers to develop alternative sources of energy. Among the new technologies being developed are hydrogen fuel cells, which young scientists...

Scholars investigate how the tempo of music affects heartbeats. Groups  develop hypotheses about music and its connection to heartbeats before carrying out an experiment. They analyze and present data from their investigations.

What did gender have to do with the survival rates of the Donner Party? Using comparative box plots, classes compare the ages of the survivors and nonsurvivors. Using the same method, individuals make conclusions about the...

Elementary schoolers explore how making different rectangular shapes with the same perimeter has an affect on the area of those shapes. Learners use the worksheet embedded in the plan to design their own skateboarding track. They use...

Introduce starting space scientists to the electromagnetic spectrum, expecially the portion of visible light. Teach them about wavelength and frequesncy. Then give them a roll of adding machine tape and a manila folder to make a...

Here is a lesson that takes an interesting approach to analyzing data using box and whisker plots.  By using an applet that dynamically generates Venn diagrams, the class forms a strategy/algorithm for guessing the rule that fits...

Why do shadows look different in the summer than in the winter? What causes day and night? How can a sundial be used to tell time? Answer these questions and more through two engaging lessons about light and shadows. Fourth and fifth...

Review for the test with a comprehensive list of terms and concepts for the unit on congruence and similarity. It divides divides the sections in the order of the lessons presented during the unit. 

Water, water, everywhere? Each pupil first uses an Internet program to select 50 random points on Earth to determine the proportion of its surface covered with water. The class then combines data to determine a more accurate estimate.
