Law of Definite Proportions
The law of definite proportions states that a chemical compound always contains exactly the same proportion of elements by mass. The French chemist Joseph Proust conducted several experiments between 1798 and 1804 to make this discovery. At the time (before Dalton had proposed his atomic theory)...https://education.ti.com/en/activity/detail/law-of-definite-proportions

Science TODAY™ - More of U.S. (formally Science TODAY™ - More the Merrier)
Students examine the USA TODAY Snapshot™ "More of U.S.", construct a graph from the data, produce a mathematical model (linear) for the data, determine the rate of change for the data, and make predictions about future population levels.https://education.ti.com/en/activity/detail/science-today--more-of-u-s--formally-science-today--more-the-merrier
Vernier - Microscale Acid-Base Titration
In this activity, students' will use a pH sensor to determine the change in pH during a titration of a known concentration of NaOH and unknown concentration of HCl. Students' will determine the concentration of unknown HCl.https://education.ti.com/en/activity/detail/vernier--microscale-acidbase-titration
Vernier - pH
Students use a pH sensor to measure the pH level of water in a stream or lake. They examine how air pollutants like sulphur dioxide, nitrogen oxides, and carbon dioxide cause acid rain, which affects the pH of water bodies and aquatic organisms.https://education.ti.com/en/activity/detail/vernier--ph
Gas Laws introduction (Boyle's and Charle's Law)
The activity contains a simulation of Boyles law and Charles law.https://education.ti.com/en/activity/detail/gas-laws-introduction-boyles-and-charles-law
What Does a Buffer Do?
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 soda and tonic water. A comparison of the results will allow...https://education.ti.com/en/activity/detail/what-does-a-buffer-do

Titration Experiment
This activity is a fast and safe microscale experiment which allows students to quickly determine the molariy of three weak acids (vinegar, soda, and citric acid). Since the process involves a monoprotic, diprotic, and a triprotic acid, students recieve good exposure to the stoichiometry involve...https://education.ti.com/en/activity/detail/titration-experiment
Vernier - Determining the Mole Ratios in a Chemical Reaction
Measure the enthalpy change of a series of reactions. Determine the stoichiometry of an oxidation-reduction reaction in which the reactants are known but the products are unknown.https://education.ti.com/en/activity/detail/vernier--determining-the-mole-ratios-in-a-chemical-reaction
