In this activity, students will use a Voltage sensor to measure the voltage produced by new dry cells of each size. They will also determine whether there is a relationship between dry cell size and voltage.

This activity will show how to properly connect wires to make a closed electric circuit. Included in this will be how to connect batteries in series and/or in parallel, and how to properly measure potential drops across a resistor and...

In this activity, students use linear measurement and calculators to investigate proportionality and determine the constant ratio between similar figures.

Students use a Magnetic Field Sensor to measure the magnetic field and the current in a solenoid. They explore factors that affect the magnetic field, study how the field varies in parts of the solenoid, and determine the permeability...

Buffers are solutions that resist a change in pH. In this activity, students will add HCl dropwise to a measured amount of water, monitoring the pH. Students then repeat the process, using a simple buffer prepared by combining baking...

The USA TODAY Snapshot allows students to use scientific notation with real-life data. Students will work with large numbers when determining the height of a stack of $20 bills. Unit conversion will be used from one unit of measure to...

Students will measure the circumference of their fist and list their shoe size. The lists will be loaded using TI-Navigator in the activity center.

In this activity, Students can use a Force Sensor to measure the force needed to lift an object and the force needed to pull the same object up an inclined plane. They will also calculate work done and efficiency and make conclusions.

In this activity, students' will use a pair of motion detectors to record the cartesian coordinates of a rod moving in a star-shaped pattern and calculate the distances moved between the vertices of the star. They also compare these...

Students use the pH sensor to measure changes in the pH when CO2 dissolves in water. They also study the changes in the pH when sulphuric acid is added to water and identify water bodies most likely to be affected by acid rain.

In this activity, students can use a voltage sensor to measure the voltage produced by new dry cells of each size. They will also determine whether there is a relationship between dry cell size and voltage.

in this activity, students calculate the molar enthalpy of dissolving for three ionic solids, and use this information to design a cold pack. In this experiment they measure the heat changes which occur from various salts dissolving in...

In this activity, students can use an EasyTemp probe to measure the temperature of hot water and determine its boiling temperature. EasyData is needed for this activity.

This App contains five games that reinforce skills from the number and operations, geometry, and measurement standards. These games help students build skills in ordering numbers, choosing equivalent fractions, estimating and drawing...

In this activity, students estimate statistical measures and find confidence intervals.

Students use the EasyTemp Probe to measure the temperature of hot and cold water before and after mixing. Students compare the mixing temperatures to a linear prediction. EasyData is needed for this activity.

In this activity, students can use a Heart Rate Monitor to measure their heart rate while sitting, lying down, and standing. They will analyze the data collected to determine the effect of body position on heart rate.

In this activity, students' use a motion detector to the measure the reaction time of students. They graph the data from trials conducted in the class and analyze trends. They then calculate drop distance from reaction time.

In this activity, students will measure angles and investigate the relationships between interior and exterior angles of a triangle. They understand the definition of interior angles, exterior angles, adjacent angles, supplementary...

In this activity, students' will measure their heights using a motion detector and describe the data using the statistical concept called box plot.

JASON Aquatic Field Study: Explore how the pH of an aquatic site determines if the water is acidic, basic, or neutral by performing an experiment at a local aquatic site to measure the pH level.

In this activity, Students can use a Motion Detector to measure distance and velocity.

Using similar triangles, a relationship is established between the six trigonometric functions of an angle and simple line segments. These relationships are then confirmed using line segment measurement capabilities of the graphing...

This activity is adapted from one of the TI books. Students measure lengths and widths of rectangles and record for the class to see. Each group's rectangle has the same perimeter, but different areas. After a discussion, students make...
