Punnett Square
In this activity students will explore the rules of Mendelian Genetics using a single trait, height, in pea plants. A monohybrid cross using a simple Punnett Square is performed. Students can randomize their parental generation using the reset button so they can explore all facets of dominant and...https://education.ti.com/en/activity/detail/punnett-square
Entropy
In this activity, students will investigate entropy from the point of view of microstates, macrostates, and probability. The goal of the activity is to help students better understand the relationship between probability and entropy. Students will learn that, in the case of the second law of ther...https://education.ti.com/en/activity/detail/entropy

Enzyme Chemical Reactions
In this lesson, students will use an enzyme catalase to speed up the breakdown of hydrogen peroxide into oxygen.https://education.ti.com/en/activity/detail/enzyme-chemical-reactions
The Fibonacci Sequence
One of the simplest and beautiful mathematical sequences. The simplicity: 1, 1, 2, 3, 5, 8 ... is such that each term is the sum of the previous two terms. Examples of the sequence can be found in nature, architecture and number theory. In this investigation, students explore some of the patterns...https://education.ti.com/en/activity/detail/the-fibonacci-sequence
