Activity: Dimensional Analysis Show Down
In this activity students will work cooperatively to solve conversion based problems using dimensional analysis. Students are required to independently determine an answer for each question and be able explain their method of solving with their peers. This activity is designed to allow students to work at their own pace, and for students to take on a teaching role by communicating their understanding with their peers.

Lesson Plan: Chemistry Basics Unit Plan
The AACT High School Classroom Resource library and multimedia collection has everything you need to put together a unit plan for your classroom: lessons, activities, labs, projects, videos, simulations, and animations. We searched through our resource library and constructed a unit plan for introducing the basic chemistry concepts to students: Laboratory Safety, Equipment, and Reports, Periodic Table Basics, Physical and Chemical Properties and Changes, Endothermic and Exothermic Changes, and Classification of Matter. These topics are very important for your students to master before they dig into other chemistry concepts. This unit is designed to be used at beginning of the school year.

Observations, History, Conservation of Mass, Measurements, SI Units  High School, Middle School
Activity: Lavoisier Video Questions
In this activity, students will watch a video about Antoine Lavoisier, who many consider to be the father of modern chemistry. They will answer questions as they learn about oxygen, hydrogen, and the first proposal of the Law of the Conservation of Mass.

History, Mole Concept, Measurements  High School
Activity: Avogadro Video Questions
In this activity, students will watch a video about Amedeo Avogadro and answer related questions. They will learn that he is the scientist given credit for the mole concept and that he also made several other discoveries in chemistry.

Physical Properties, History, Measurements, Temperature, SI Units, Accuracy  High School, Middle School, Elementary School
Activity: Temperature Guys Video Questions
In this activity, students will watch a video and answer questions about how both the thermometer and the concept of temperature evolved over time

Conservation of Mass, Measurements  High School, Middle School
Lab: Mass of a Gas
In this lab, students will perform a simple chemical reaction in a closed system to produce a small amount of gas. They will collect mass measurements for the reactants and the products in order to demonstrate the conservation of mass during the reaction. They will also release the produced gas from the closed system in order to verify that gasses have mass.

Observations, Density, Measurements  High School, Middle School
Lab: Penny Boats
In this lab, students will explore Archimedes’ Principle and how it relates to density. Each student will be given a piece of aluminum foil and asked to design and build a boat that will hold as many pennies as possible without sinking when placed in water.

Lab: Chemistry Composition Challenge
In this inquiry based lab, students will design a method to solve three chemistry problems involving moles, molecules, and density.

Accuracy, Measurements, Significant Figures, SI Units
Simulation: Measuring Volume
In this simulation, students will participate in a 10 question quiz. The quiz questions are each made of two parts, with the first part requiring the student to analyze an image of a graduated cylinder in order to report an accurate measurement. Students must use the correct number of digits based on the markings presented on the cylinder when reporting the measurement. In the second portion of the question the students will determine the uncertainty value of the graduated cylinder, again by analyzing its markings. The simulation is made up of several different sizes of graduated cylinders, each containing unique markings, so students will be challenged to analyze each individually.
