Doug Ragan has been working with the Alchemie team -- founded by a former chemistry teacher, Julia Winter -- for a number of years. They have been working over the last year on a new project, named Kasi, which delivers sound-based feedback to students as they learn with tactile pieces on a magnetic whiteboard. The goal is to build an accessible learning system that helps ALL students learn, and is particularly important for those with visual impairments.
Melissa Hemling shares her favorite manipulatives along with cheap at-home alternatives to help students visualize VSEPR.
Learn how to give pennies a beautiful, silvery-colored plating.
What is the pressure inside a bottle of soda pop? Read this short article to find the surprising answer to this question, and also to learn how to do an experiment to answer this question for yourself!
Learn how to thermochemically analyze the Devil's Milkshake chemical demonstration - just in time for Halloween!
In this lab students are given a film canister, a quantity of Alka Seltzer of their own choosing and any materials available in the room to investigate factors that affect the rate of reaction. They work with their groups to create CER boards and then the class engages in a Glow and Grow session. Tips for using this activity in a virtual setting are offered as well.
The use of anthocyanins in red cabbage extracts as pH indicators has long been a popular classroom activity. Flowers, fruits and vegetables contain a diverse range of anthocyanins. This investigation explores further applications of plant-derived dyes including reversible reactions based on oxidation/reduction chemistry and other reactions to illustrate colour changes that are not solely dependent on pH change. By using household materials and plant dyes, this investigation may potentially be completed at home if necessary.
What's a better way to start the new school year than with some new experiments? Learn how to use a variety of color changing experiments to teach students about the Diet Coke and Mentos experiment, acids, bases, chemical and physical changes, and climate change.
As many teachers are preparing to teach online, we are revisiting posts from the ChemEd X archives like this one that might be of help. The original Build a Boat challenge was used to help create a classroom culture of teamwork and growth mindset. The author has updated the Build a Boat activity by providing a modified slide show presentation specifically to help those teaching remotely this fall.
Learn how to form a blue-green copper compound on a penny, and then use that compound to make green flames. This is a great summer time activity for your next campfire!
