Students engage in a lesson which shows them that celestial navigation is the art and science of finding one's geographic position by means of astronomical observations, particularly by measuring altitudes of celestial objects - sun,...

Students calcute distances using trigonometry and angle measurements. They estimate the width of the Trig River, measure it and compare their results with their classmates. They collaborate with a group to research and find the results.

Students work to increase the intensity of a light bulb by testing batteries in series and parallel circuits. They analyze Ohm's Law, power, parallel and series circuits, and ways to measure voltage and current.

Young scholars share opinions about measures recently passed in their school, vote on and argue for and against hypothetical school policies, and respond to a "president's" decision to pass or veto the measures.

Students use everyday materials (milk cartons, water bottles, pencils, straws, candy) to build a small-scale transportation device that incorporates the wheel and axle and the lever. They race their carts/trucks, measure distance, time...

Learners examine how wind energy is transformed into electrical energy. In pairs, they build miniature wind turbines and measure how much electrical current they produce. They asses the importance of design and position in energy...

Students investigate how to read a topographical map and triangulate with just a map. They convert a compass measurement to a protractor measurement, reverse a bearing direction, and using a worksheet take a bearing of certain landmarks...

Students create their own play dough to use for art projects. In this art lesson, students measure, pour and mix the ingredients to make their own play dough. Then, students use the clay to create their own sculptures.

High Schoolers investigate the perpendicular bisector of a line segment. They use Cabri Jr. to construct the perpendicular bisector of a segment. The dynamics capabilities of Cabri Jr. allow your learners to observe the lengths of the...

Students examine how navigation is based on mathematics and how making a mistake in measuring an angle could have an impact on a target. They observe a teacher-led lecture, use a calculator to complete two worksheets, and participate in...

Students aim to explain the need for standardization of units of measurement. They pose their own standards for the value of a kilogram and compare them with the currently used standard.

Students examine the different types of wind patterns. Using common materials, they construct weather vanes to measure and record wind direction over a two-week period. After analyzing the data, they draw conclusions about the...

Learners revisit midpoint and segments by graphing on the TI or computer. This activity can be done with pencil and paper, but is more interactive if it is done on a TI-navigator.

Students conduct an experiment.  In this salinity lesson plan, students learn about sea ice, why it is important and how changing amounts can affect the sea.  Students conduct an experiment to find out the effects of salinity...

Fourth graders develop an understanding of how engineers use wind to generate electricity. They will build a model anemometer to better understand and measure wind speed. They discover that engineers design wind turbines that generate...

Students assess the factors which influence the sensation of being "cold" in a particular situation. They study the complexities in measuring temperature by reading and discussing the article "Beyond Brrr: The Elusive Science of...

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...

Students brainstorm and share opinions about products that can be reused or recycled after reading the article, "Seattle's Recycling Success Is Being Measured in Scraps." They then investigate, analyze and evaluate articles on recycling...

Young scholars drop water from different heights to demonstrate the conversion of water's potential energy to kinetic energy. They see how varying the height from which water is dropped affects the splash size. In seeing how falling...

Students analyze the relationship between radius and diameter.  Students read Sir Cumference and the First Round Table then take measurements of circular items from around the room.  Students compute the radius, diameter...

Students determine whom they consider "the best" performer in a variety of entertainment industries and discuss how to accurately measure greatness. They create bar graphs comparing statistics of the 1975 Cincinnati Reds and the 1998 New...

Learners act as commissioners researching needed safety standards for vehicles and highways. They then draft recommendations to be included in a new highway safety bill. They cite reasons a particular measure would reduce fatal highway...

Pupils examine the centroid of a triangle as they use Cabri Jr. to construct a triangle and its medians. The dynamic nature of the software allows learners to measure the lengths of the segments in the triangle and conjecture and verify...

Learn how to calculate the length and midsegments of triangles. Young scholars differentiate between similar and congruent triangles. They create a spreadsheet with their findings.
