Ohm's Law
In this activity, students will explore the relationship between current and potential difference for several resistors which obey Ohm's Law. They will experimentally measure the resistance of the resistors. Students will then examine the relationship between current and potential difference us...https://education.ti.com/en/activity/detail/ohms-law
Which Way?
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.https://education.ti.com/en/activity/detail/which-way
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.https://education.ti.com/en/activity/detail/two-hot-two-cold
Forensics Case 10 - Dropped at the Scene: Blood spatter analysis
