Collaborative Analysis Experience Students will apply knowledge to a real-world situation. Any questions about the Atomic Mass Calculations Practice? ADVICE:  #2 doesn’t require any math.  #5 is really tough! I will help you with it if you can’t figure it out. FROM YESTERDAY…

Calculators Look for any of the following buttons on your calculator. (They may be 2 nd functions.)  EE  EXP  x10 n Use these buttons to enter scientific notation into your calculator. NOTE: I know that many of you believe that the ^ button works, but it is inconsistent with our calculations. You’ll only get about 50% correct.

Useful to know how much energy is coming out of an atom Useful to know how much energy to put into an atom to achieve a particular color Useful to calculate the energy c = λν c = 3.0x10 8 m/s E = hν h= 6.626x J·s

Collaborative Analysis Experience Students will adapt knowledge to an unpredictable situation. Flame Test Experiments and the Electromagnetic Spectrum As we watch the video, let’s: 1)Estimate the wavelength of the light based on its color 2)Calculate the frequency of the light 3)Calculate the energy of the light

Collaborative Analysis Experience Students will apply knowledge to a real-world situation.

Collaborative Analysis Experience Students will apply knowledge to a real-world situation. Let’s learn how fireworks are made.
