Need a great lab activity to engage your students and light up your classroom? This activity combines everything that students love: lab work, flames and color.
In this lab your students will try to identity the following six metal salts based on their emission colors.
Calcium chloride: Orange
Copper chloride: Blue green
Lithium chloride: Red orange
Sodium chloride: Yellow
Potassium chloride: Light violet
Strontium chloride: Red
Just like every person has a unique finger print, the color of light emitted by a metal when heated in a flame is unique to that metal. The emission colors can therefore be used to identify specific metals. When the metal salts are placed in the flame the electrons in each atom absorb energy. This energy is used to move the electrons from their ground state to an excited state. When the electrons move back to a lower energy level they emit the absorbed energy as a particle of light called a photon.
You can see a video of the flame test colors on my YouTube channel.
I hope you enjoy this great activity, I know your students will.

This guided inquiry lab from my Tes shop will help your students gain an in depth understanding of the difference between resistors in series circuits and resistors in parallel circuits. I have done these activities with my students many times and they always find them fun and engaging. The best part is that your students won’t even know they are learning as they complete the inquiry-based laboratory assignment sheet that is included. The PhET Circuit Construction Kit: DC simulation can be found at this link: https://tinyurl.com/m2pdgg4
These guided inquiry activities are intended to be used with one of the two HTML5 Circuit Construction Kits from PhET Interactive Simulations. With these activities your students can quickly build electric circuits and collect accurate data that will allow them to compare the characteristics of resistors in series with resistors in parallel. With a little up-front guidance your students will be able to complete the activity with little assistance. The goals of these activities are that your students will understand:
(1) how the voltage drop across resistors changes when resistors are added in series and parallel (Kirchhoff’s voltage rule).
(2) how the current through resistors changes when resistors are added in series and parallel (Kirchhoff’s current rule).
(3) how the equivalent resistance changes when resistors are added in series and parallel.
(4) how the power output (bulb brightness) of the resistors changes when resistors are added in series and parallel.
(5) how removing one resistor from the circuit changes the behavior of the remaining resistors for series and parallel circuits.
