ATOMIC AND ELECTRON STRUCTURE, CONTINUED
Spectroscope
This inexpensive, handheld diffrac- tion grating spectroscope will measure wavelengths of light from 400–700 nanometers (nm) with
an accuracy of ±5 nm. Great for use with spectrum tubes or when doing flame tests. Students will better understand spectra after using this quantitative analysis spectroscope. Unit is housed in an unbreakable plastic case. Overall length, 20 cm; scale length, 37 mm. Instructions for laboratory use are included.

Atomic Target Practice—Rutherford Scattering and the Nuclear Atom—
Super Value Guided-Inquiry Kit
Rutherford’s discovery of the nucleus involved shooting alpha particles at gold foil atoms and observing the scattering angles. In this activity, students shoot marbles from various angles at an unseen object and trace the marble paths after deflection to estimate the target’s general size and shape. Includes wood shapes, marbles, materials to construct “black boxes,” student handouts and complete Teacher Notes. SuperValueKitiscompletefor8studentgroups.

Spectrum Analysis Chart
This full-color chart is a great when teaching spec- trum analysis. The bright line (emission) spectra of ten elements are shown along with the electromag- netic spectrum with a detailed visible spectrum, solar spectrum, Doppler Effect and more. Line drawings illustrate the methods of producing various spectra and the applications of spectrum analysis. A great companion for spectrum tubes, spectroscopes or flame tests. 69 x 119 cm.

Electron Configuration Bingo—Super Value Game
Introduce the Aufbau principle, Pauli exclusion principle and Hund’s rule with electron configuration bingo cards. Clues lead students to cover the correct electron configura- tion as they learn about noble gas cores and valence electron and ion configurations. Includes Teacher Notes tips, bingo chips, clues, electron order of filling diagram, Periodic Table and bingo cards. Super Value Game is complete for 24 students working individually.
