Science Practice: Planning and Carrying out Investigations
Teaching and Evaluating Science Practices—Planning and Carrying Out Investigations
Ben Meacham | Thu, 11/14/2019 - 21:27
Several resources are available to support teachers as they incorporate science practices into their curriuculum. The author shares how he and his colleagues focused on improving their coverage of the practice of planning and carrying out investigations.
Chemical Tests on Coins
Tom Kuntzleman | Mon, 09/16/2019 - 20:07
Simple chemical tests are described that can indicate the presence of certain metals in coins. A wide variety of chemical concepts are involved. The experiments described are a natural fit for the 2019 National Chemistry Week theme of "Marvelous Metals!"
Advanced Chemical Lab Design
Erica Posthuma | Mon, 09/16/2019 - 10:35
I had the opportunity to develop an advanced chemical lab design course for a small group of ambitious students. I have outlined the resources I used and how I pulled the course together,
First Day Chemistry Engineering Activity
Melissa Hemling | Sat, 09/07/2019 - 22:26
It is difficult to find a lab to do on the first or second day of school. This engineering lab fits the bill!
Gas Laws and Deflategate
Ben Meacham | Thu, 08/15/2019 - 02:56
If you are looking for ideas to create an authentic opportunity for students to apply their knowledge of gas laws while integrating some of the most important science practices, then this activity may fit your needs.
The Liquid Nitrogen Cloud
Tom Kuntzleman | Fri, 07/26/2019 - 10:42
Have you ever seen the liquid nitrogen cloud? Do you wonder how the cloud forms when hot water is thrown onto liquid nitrogen? This post explores the liquid nitrogen cloud and possible explanations for its formation.
Detection of Nickel Cations in Coins
Andres Tretiakov | Tue, 05/07/2019 - 22:45
It is not known why people develop allergies to nickel and there is no cure. The best course of action to prevent an allergic reaction is to avoid contact with products containing nickel. This article will explain how to make an easy and cheap nickel detection device that will limit or eliminate the risks of exposure to sources of nickel using some interesting classic chemistry.
AACT Science Coaches
Lauren Stewart | Tue, 04/30/2019 - 08:03
I was excited for the opportunity but I never thought my science coach would be interested in developing and executing lessons with me. Luckily for me, my experience ended up being nothing like what I expected. You can apply for this experience too. The deadline to apply for Science Coaches for the 2019–2020 school year is September 1, 2019.
Citrus Fruit Peel Powder and its Capacity to Remove Copper From Wastewater
Andrea Amato | Mon, 04/15/2019 - 17:15
Biosorption is a method that can be used for the removal of pollutants from wastewater, especially those that are not easily biodegradable. This experiment uses citrus fruit peels as part of a iodometric titration to conduct a wastewater treatment binding copper.
