HS-PS1-2 Chemical Reactions

Students who demonstrate understanding can construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.

Summary

Clarification

Examples of chemical reactions could include the reaction of sodium and chlorine, of carbon and oxygen, or of carbon and hydrogen.

Give Me Back My Copper! A Simple, but Multi-Faceted Lab Activity to Review Lab Skills in Week One of AP Chemistry

// Monday, April 18, 2016 • Allison Tarvin

In the lab, students are given a 1.5 gram samples of copper. The copper is taken through a series of five chemical reactions ending with the precipitation of solid copper. After the five reactions, students are asked to return their 1.5 gram samples of copper to the teacher.

Using Chemistry to Find that Silver Lining

// Thursday, March 3, 2016 • Tom Kuntzleman

I recently gave a public lecture on my campus in which (among other things) I discussed the chemistry of metallic copper, silver, and gold.

Rethinking Stoichiometry

// Wednesday, February 3, 2016 • Lauren Stewart

Stoichiometry is arguably one of the most difficult concepts for students to grasp in a general chemistry class. Stoichiometry requires students to synthesize their knowledge of moles, balanced equations and proportional reasoning to describe a process that is too small to see.

Relative Reactivities of Metals

// Thursday, December 17, 2015 • Dan Meyers

Last winter I watched a webinar put on by ACS and AACT called "NGSS in the Chemistry Classroom." As a result of watching that webinar, I took an activity that had NGSS Science & Engineering Practices (SEP) integrated into it and tried it out in class. In this activity, students are required to develop their own procedures and data tables.

An Orange to Black Halloween Chemistry Demonstration You Can Do with Household Items

// Tuesday, October 27, 2015 • Tom Kuntzleman

By Tom Kuntzleman, Tori Talaski, and Quincy Banini Want a great experiment to have your students perform during the Halloween Season? Try this one that involves an orange to black color change:

Harry Potter and the Elephant Toothpaste Potion

// Tuesday, April 28, 2015 • Tom Kuntzleman

The “Elephant Toothpaste” experiment is a very popular, albeit messy chemistry demonstration. To carry out this experiment, place a 250 mL graduated cylinder on something that you wouldn’t mind getting messy.

Observing a Chemical Reaction (NGSS Modified)

// Friday, December 12, 2014 • Dan Meyers

In a recent post, I indicated that I would make available the Chemical Reactions lab that I modified to meet NGSS guidelines. Enjoy!

Sodium carbonate reacts with hydrochloric acid producing bubbles

Mass of a Reaction Product

// Wednesday, October 29, 2014 • David Licata

OBJECTIVE: To use the principles of stoichiometry to determine the theoretical yield of a simple reaction, measure the actual yield, and calculate the percent yield.

Complex Ions Lab

// Wednesday, March 19, 2014 • mamorgan@me.com

This laboratory exercise accompanies the article "A guided group inquiry lesson on coordination compounds and complex ions". The laboratory serves as part of an extended exercise on the chemistry topic of coordination compounds and complex ions.

Types of Chemical Reactions

// Wednesday, January 15, 2014 • Deanna Cullen

I expect that most high school chemistry teachers assign some type of laboratory related to types of chemical reactions including synthesis, decomposition, single replacement and double replacement reactions. I have used several published versions, but I am sharing my modifications.
