It is difficult to find a lab to do on the first or second day of school. This engineering lab fits the bill!
Science Practice: Planning and Carrying out Investigations
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.
Why Do Dead Batteries Bounce? Chemistry, of Course!
Tom Kuntzleman | Fri, 04/05/2019 - 07:16
Did you know there is a simple test you can do to see if an alkaline battery is fresh or dead? All you need to do is bounce the bottom of a battery onto a hard, flat surface. Guess what causes this difference in bouncing ability between fresh and dead batteries? Chemistry, of course!
Simple Demonstration of The Warming Effect of Carbon Dioxide
Tom Kuntzleman | Tue, 03/26/2019 - 12:22
Looking for Earth Day activities that connect chemistry and climate change? Check out this experiment, which demonstrates the warming influence CO2 has on our atmosphere.
NGSS-ify Alka-Seltzer Rockets
Stephanie O'Brien | Tue, 02/19/2019 - 18:50
Given a guiding question, students determined what they wanted to test, did the experiment and got their CER boards ready for review. Instead of a regular argumentation session, we had a glow and grow session, where students had to provide positive and negative feedback for each board.
Mole Unit Mini-Practicums
Lauren Stewart | Thu, 02/07/2019 - 17:59
We all know how fundamental the mole concept is for stoichiometry. This year I brainstormed ways to really make it stick. I decided to do multiple mini-practicums, one for each learning target of the mole unit. I am sharing brief descriptions of the mini-practicums I did for each learning target.
