Students' use a motion detector to examine how different types of motion affect the shape of the Distance versus Time plot. They explore how changes in direction and other factors affect the shape of the plot.
In this activity, students will use the motion detector to record motion, and observe how the direction of movement, speed of travel, and the rate of change of direction and speed affect the shape of a Distance-Time plot.
Coming to know F and C
Students will collect room temperatures with temperature probes and graphing calculators, and plot data to generalize rule that relates Fahrenheit and Celsius units.
The 1 Cent Event
In this activity, students will collect data on a 1 cent coin as it falls under its own volition after being placed on its edge 25 times. They will report their data to the class and enter the data into their TI-84 Plus. They will examine the data from the collective and discuss patterns revealed in the data.
Inverse of Two Temps
Students find a conversion equation that will calculate the corresponding Celsius temperature for any given Fahrenheit temperature. Students learn to graph scatter plots, analyze and graph linear equations, compute and model slope, derive and apply a conversion equation, and analyze inverse relations.
Slow Down - Speed Up
In this activity, students' will use a motion detector to observe the effect of speeding up, slowing down, and moving at a constant rate on a Distance versus Time plot.
Walk the Line
In this activity, students' will create constant-speed motion plots and develop linear equations to describe them mathematically.
In this activity, students will construct a pendulum and create a motion plot for a swinging pendulum. They will also identify characteristics that affect a pendulum's motion.
What's Your Speed?
In this activity, students' will use a motion detector to determine what effect the speed at which a person moves has on the appearance of the Distance versus Time plot.
In this activity, students will create Distance versus Time plots and calculate the slopes of the plots. They explore the mathematical concept of slopes and understand how slopes can be used to interpret how one physical quantity changes with respect to another.
In this activity, students move in a specific way in front of the motion detector to create motion plots that match a given Distance versus Time plot. They make connections between types of movements and characteristics of Distance-Time graphs. They learn to change the shape of the plot by adjusting the starting point, speed, and the direction of motion.
In this activity, students' will determine the average speed of a falling object. They will observe whether or not changing the mass and keeping the same shape have an effect on the average speed of the object.
Two Hot, Two Cold
In this activity, students collect both Celsius and Fahrenheit temperature data for several water samples of varying temperatures. They use the data to find a conversion equation that will calculate the Fahrenheit temperature for any given Celsius temperature.
In this activity, students' will create a Height-Time plot for a bouncing ball and use a quadratic equation to describe the ball's motion.
Making Cents of Density
In this activity, students will measure the mass and volume of several collections of a coin type and enter the data into their handhelds and explore for patterns.
Students will also make a plot of mass vs. volume and create a mathematical model that demonstrates the relationship between mass and volume.
Vernier - Lemon "Juice"
"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 study some basic principles of cells using the juice of a lemon as the cell solution. You will place small pieces of two different materials into the lemon, and a calculator will be used to measure and display the voltages produced.
An ounce of prevention
Students will collect measures off of containers for the volume in both milliliters and ounces. They will set up a plot to determine the relationship
between the two measures. Students will predict values for volumes in one unit, given the other.
Vernier - A Speedy Slide with EasyData™ App and CBR 2™
Students will use a CBR 2™ motion detector to determine their speed or velocity going down a playground slide. They will also experiment with different ways to increase their speed going down the slide.
Vernier - Friction
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.
Vernier - Heat of Fusion
In this activity, students will 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.
How Do Your Errors Grow!
A simple measuring activity allows students to explore the sometimes difficult concept of significant figures, both manually and with the help of the Science Tools App's Sig-Fig Calculator.
Vernier - Graphing Your Motion
In this activity, students use a Vernier Motion Detector to measure distance and velocity. Students prepare graphs of motion and analyze them. They compare and match graphs of distance versus time and velocity versus time.
