Forensics Case 11 - Ashes to Ashes: Using evaporation rate to identify an unknown liquid
In this activity, students understand that evaporation rate is a characteristic property of a liquid. Based on this fact, they identify the solution and the likely accelerant in a case of arson. They compare the evaporation rates of the accelerants found with the suspects with those near the crim...https://education.ti.com/en/activity/detail/forensics-case-11--ashes-to-ashes-using-evaporation-rate-to-identify-an-unknown-liquid
Forensics Case 3 - Name That Tune: Matching musical tones through waveform analysis
In this activity, students analyze sound waves to calculate the frequency or pitch of musical notes. They use a Microphone to detect the waveform of a musical note. Students calculate the frequency of a musical note from the period of its waveform and use this knowledge to identify the musical n...https://education.ti.com/en/activity/detail/forensics-case-3--name-that-tune-matching-musical-tones-through-waveform-analysis
Infinite Geometric Series
Students explore infinite geometric series. They will consider the effect of the value for the common ratio and determine whether an infinite geometric series converges or diverges.https://education.ti.com/en/activity/detail/infinite-geometric-series
Angles of a Triangle
This activity explores the various relationships of the angles of a triangle. It starts with an interior angle and its corresponding exterior angle. Then the sum of the interior angles. Finally, the relationship between one exterior angle and its remote interior angles. The students are prov...https://education.ti.com/en/activity/detail/angles-of-a-triangle_2
Investigation of Similar Rectangles
This activity shows how the ratios of perimeters and the ratios of areas of similar rectangles compare to the similarity ratios.https://education.ti.com/en/activity/detail/investigation-of-similar-rectangles
The Integrated Medical Model
As NASA is designing a new spacecraft capable of taking humans into deep space, and with the future advent of commercial spaceflight, a deeper and better understanding of medical risk has become even more vital for maintaining spaceflight safety and health for humans.https://education.ti.com/en/activity/detail/the-integrated-medical-model
Sampling
Students learn about each of the four types of random sampling methods and use the randInt command to find each kind of sample from a given population.https://education.ti.com/en/activity/detail/sampling_1
Testing Claims About Proportions
Students find z-scores and critical values to test claims about proportions. To verify the results, they find P-values by either finding the area under the curve with the Integral tool, or by using the 1-Prop z Test command.https://education.ti.com/en/activity/detail/testing-claims-about-proportions_1
Z-Scores
This lesson involves finding the area under the standard normal curve with mean 0 and standard deviation 1 for a given distance from the mean and compare this to the area under the curve for another member of the family of normal curves.https://education.ti.com/en/activity/detail/zscores
Square it Up!
Students investigate the method of least squares by adding the squares to a scatter plot and moving a line to find the minimum sum. Then they compare their line to the built-in linear regression model.https://education.ti.com/en/activity/detail/square-it-up
Candy Pieces
Students will be introduce to hypothesis testing. Students are given the number of pieces by color in a bag of candy.
