In this activity, students measure weight, height, and length with the help of a balance, scales, rulers, yardstick, and tape measures. They use their TI-10 to find proportions and to round off answers to whole numbers.

One method of measuring phosphate concentration is by using a Colorimeter. This instrument measures the amount of light transmitted through a sample at a given wavelength.The amount of light absorbed is mathematically related to the...

Students investigate the relationship between measure of central and inscribed angles in a circle.

This activity uses Cabri Jr to classify triangles according to their angle measure. [Requires Adobe Reader.]

In this activity, use an interactive, and investigative approach to determining the sum of the interior angles of a quadrilateral. They use Cabri Jr. to draw, measure, and calculate the characteristics of the angles of quadrilaterals.

In this activity, students compute statistical measures like the mean, standard deviation, and variance of the data set. They understand how measures of variability can be interpreted.

A CSI activity that deals with "TRENDS IN DATA". You'll conduct an investigation whereby you'll measure parts of your body and contribute to the investigation data to solve a murder. You'll look at different relationships to find proper...

Students construct a line parallel to the base of a triangle and measure the angles formed. They use the construction to prove that the sum of the measures of the interior angles of a triangle is 180 degrees.

Students understand statistical concepts like center of data and the amount of data variation from the center. They calculate the measures of the center of a distribution and the measures of spread for the data collected as a list....

This activity is designed for students to make conjectures about triangles. Students will create three lists to represent the measures of the angles of the triangle. The entire class list will then be sent to each student for analysis,...

In this activity students will learn how to make a simple pendulum. Students' will use a motion detector to measure the period of a pendulum and calculate its acceleration.They will also understand the effect that gravity has on the...

In this activity using the USA TODAY Snapshot, "Coming clean about showering time," students will find the measures of central angles and arcs of a circle. They will use circumference, radius, concentric circles and degrees in a circle...

This activity will help young scholars visualize the construction of congruent triangles and conceptualize properties through measurement and movement of their construction. Students will need access to the TI-84 Plus Family.

In UCM, the net force called Fc is equal to mv2/r and is directed toward the center. This is demonstrated by an object that is suspended by a string and is moving in a circular path which makes a conical pendulum. In this experiment, you...

Students study how the nature of two materials in contact, and the smoothness of their surfaces affect the magnitude of the sliding force of friction. They use a force sensor to measure frictional force for different surfaces.

In this activity, students examine data and make graphs to represent the data. They interpret the data and answer questions. They also learn to calculate percentages and angle measures.

Students will measure the lengths of the sides of three different triangles and apply Heron's Formula to calculate the area in acres. The measurements for this activity may be done outside or, using a specified scale, completed inside....

In this activity, students' will use a heart rate monitor to measure their heart rate in beats per minute (BPM) while they exercise. They will understand the effect of exercise on heart rate and learn how to measure differences in heart...

Student uses the Nitrate Ion-Selective Probe to measure the Nitrate ions concentration in water samples. In another method, student converts nitrate ions to nitrite and uses the Colorimeter to measure nitrite and calculate the nitrate...

Students find ratios and calculate measures of central tendency for sets of data. They understand the concept of the Golden Ratio. They use box-and-whisker plots to analyze data.

Using Cabri Jr, the students (with the teachers help) will create parallel lines cut by a transversal, measure angles, and compare the relationships of the angles formed using features of the Cabri Jr.

Using Cabri Jr. to explore the connection between central and inscribed angles along with their arc measure.

In this activity, students will investigate properties of angles and arcs formed when chords, secants, and tangents intersect and intercept arcs in a circle. They discover several important theorems concerning circles and arc sizes. They...

I use this activity in the beginning of the school year when introducing terminology such as angles, lines, segments, measures, perpendicular etc. The original material is from the SIMMS Integrated Mathematics using Technology, I have...
