Whiteboards are great learning tools in a science classroom. With these instructions, you can make eight 24-in x 24-in whiteboards for less than $2.00 each! Instructions for simple whiteboard stands are included.
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.
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.
My district recently provided a professional development session focused on utilizing three dimensional formative assessments in the classroom. The ideas I learned in the session as well an an activity for students to engage in formative assessment are outlined.
In honor of the International Year of the Periodic Table: A familiarity with the chemistry of some of the elements more commonly encountered in everyday life is a valuable learning experience for all students. Nitrogen is the third in this series of elements to be discussed as part of the Element of the Month program. #IYPT

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.
Chemistry is difficult to learn. Walk into any chemistry classroom, and you’ll be soon confronted with many abstract concepts. Abstract ideas have no physical form, and as a result, they are difficult to understand.
