Students use a Conductivity Probe to measure change in conductivity during a chemical reaction and determine the equivalence point of the reaction They determine the mass of the product and calculate the molar concentration of the...

This activity has students discover the relationship between parallel and perpendicular lines and their slopes. After constructing these objects using CABRI Geometry II for the TI-89, slopes are measured. [Requires Adobe Reader.]

Sinusoidal data already obtained by swinging a can over a meter stick and measuring time and displacement from its resting position using a CBR or CBL with a motion detector. Using the TI-Navigator, you can monitor their "real time"...

Students use the Motion Detector to measure the effect of air resistance on falling objects. They determine how air resistance and mass affect the terminal velocity of a falling object and then choose a force model that fits the data.

In this activity, students measure rectangles and calculate ratio between the sides. They compare the ratio to the Golden Ratio.

"Juice" is a slang term sometimes used for electricity. Batteries are made up of one or more cells. Cells often consist of two different materials in a solution that are connected to each other by a wire. In this experiment, you will...

In this activity, students use the drawing and measurement tools of Cabri Jr., to learn and understand the concept of "equidistant from the endpoints of a segment." They observe the changes if they move a point on the perpendicular...

Students will collect rainwater and measure its acidity. They will use the rainwater to determine the effect that acid rain has on limestone.

In this activity, students can use a calorimeter to measure the amount of heat needed to melt ice and determine the heat of fusion for ice. EasyData is needed for this activity.

In this activity, students can use the motion detector to measure their current height and obtain a mean value. They will use this and earlier data to plot a graph of height versus age. Students will identify the mathematical model that...

This App allows students to construct, measure, analyze, and transform geometric diagrams more accurately than with pencil and paper.

Students can use the converse of the Pythagorean Theorem to predict a triangle's classification. The Cabri Jr. App on the TI-83+/84+ family will be used to create triangles and find their measurements. Adobe PDF lab worksheets are included.

In this activity, students investigate the sum of the measures of the interior angles of a triangle. They will explore interior angles, and their relationship with the exterior angles of a triangle.

Students explore and use the concept of ratio in a real-world situation. They will make judgments regarding accuracy and precision of measurement.

The interactive Cabri Jr. geometry application makes it easy to measure the area of triangles and quadrilaterals. In this activity, students will explore some interesting area relationships in quadrilaterals.

In this activity, students will measure round objects to determine the circumference and diameter, and use the data to explore geometric concepts of the circle with statistics.

Since running a race car is VERY expensive, race engineers know a great deal about how speed, time and distance relate. In this activity, you will investigate the relationship between distance traveled, speed and elapsed time. You will...

Navigator Activity: This is a review of the right triangle in the coordinate plane. Given two lines (2 really nice ones) the students write the equation of the 3rd line to create a right triangle. They find the vertices of the triangle...

Students will study temperature changes caused by the evaporation of alkenes and alcohols and relate this data to the strength of intermolecular forces of attraction. They will also predict, and then measure, the temperature change for...

In this activity, students will measure the acceleration of a freely falling body (g) to better than 0.5% precision with the help of a Picket Fence and a Photogate.

In this activity, students use an EasyTemp Temperature Probe to measure the temperature of air next to a can of ice water. They also observe the formation of condensation and determine the Dew Point temperature. EasyData is needed for...

Rainforests at the Crossroads: Measure the CO2 level in a bottle that contains spinach leaves when it is exposed to light. Then collect CO2 data and observe the effects of photosynthesis as you add leaves in the bottle.

When two or more chemicals react, other substances such as gases may be produced. The rate at which the reaction takes place can be affected by a number of different factors including temperature. In this activity, you will see how...

Rainforest at the Crossroads: Simulate the motion of an animal using a rectangular object placed at different positions on the floor. Then measure and graph the animal's coordinates, and examine its path.
