Have you seen the rainbow candy experiment? It's a very simple experiment that involves pouring water into a plate that has M&M's candies or Skittles arranged in a pattern. Very curious shapes of sharply divided regions form spontaneously. How does this happen?!
Science Practice: Asking Questions and Defining Problems
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!
Using the online simulation tool (Atomsmith Classroom Online) and the ADI framework students investigate the properties of gases, along with two gas laws. An ADI "whiteboard discussion" helps in getting students to really process what the results of experiments mean to us as chemists - and how this leads to expanding our understanding of matter. This activity lends itself to an online classroom.
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.
Teaming up with a STEM Science Coach or mentor can be rewarding to both you and your students. I was surprised at the impact a science mentor has on students when I recieved an email from a former student.
With the school year quickly approaching, science teachers will at some point need to decide the role of laboratory investigation within their new learning environment. To help this decision-making process, the author focuses on two available options that he believes have the greatest potential for offering a legitimate approach toward authentic investigations in a digital environment.
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!
With the end of school upon us and the possibility of remote instruction in the fall, here are some techniques to address four NGSS science and engineering practices; Planning and Carrying out Investigations, Asking Questions and Defining Problems, Developing and Using Models, Analyzing and Interpreting Data.
I observe a red to blue color change when I rinse my bowl after eating frozen blueberries. Sounds like an acid-base reaction, doesn’t it? Well, read on to learn about the blueberry surprise!
