Texas Chemistry

New and expanded TEKS for Chemistry cover everything from Rutherford's discovery of the atomic nucleus to stoichiometric calculations. We have assembled a suite of student components, including videos, interactivities, and lessons for each and every new or expanded Chemistry TEKS. Correlated to the "5 E" model of Engage/Explore, Explain, Elaborate, and Evaluate, our materials provide your students with the knowledge and skills they need to master the TEKS while teacher components provide background and teacher support.

States of Matter Video: A Fresh Look at Fresh Fruit

The Untamed Science crew goes to the University of Florida to find out what chemistry has to do with fruit ripening. Then, they discover how Dalton's law of partial pressures, part of TEKS 9A, helps scientists develop techniques to keep fruit from spoiling before it reaches the table.

Go to Chemical Reactions Interactivity

Chemical Reactions Interactivity: Redox Titrations

This guided virtual lab explores how scientists determine a substance's purity by using redox reactions, part of TEKS 10H. Analysis questions offer an opportunity to demonstrate mastery of this important concept.

Go to Chemical Reactions Interactivity

Chemical Reactions Interactivity: Bomb Calorimeter

TEKS 11E requires students to use calorimetry to calculate the heat of a chemical process. This animation explores how a bomb calorimeter works and then requires students to demonstrate their understanding by answering questions.

Go to Periodic Table Interactivity

Periodic Table Interactivity: Melting Points in a Group of Elements

Students are required by TEKS 5C to explain trends in the periodic table. In this quick interactive math activity, students interpret a graph to explain the periodic trend of melting point within the alkali metal group.

Chemical Reactions Teacher Background: Stoichiometric Calculations

This document contains information on new Chemistry TEKS 8E including a content refresher, suggestions for activating prior knowledge, and the exact locations of questions that assess student understanding.

Go to Chemical Reactions Lesson

Chemical Reactions Lesson: Stoichiometric Calculations

Students learn about stoichiometry in this lesson detailing TEKS 8E. Assessment questions require students to perform stoichiometric calculations, including determination of mass relationships between reactants and products, calculation of limiting reagents, and percent yield.
