Seven practice problems are presented to physics pros in this assignment. Given the wavelengths, they perform computations for emission spectra. This brief worksheet makes an appropriate pop quiz.

First graders in kindergarten science class discuss matter. They make predictions and then identify mystery items in brown paper bags as either solid, liquid, or gas by using their senses. They discuss that a chemist is a scientist that...

In this static electricity worksheet, students complete nine questions about electron charges, coulombs, potential energy, voltage and the Van de Graaf generator.

High schoolers will identify the factors that contribute to erosion and weathering. They will start by differentiating between chemical and mechanical weathering. They then apply what they learned by playing the online jeopardy game. Key...

Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...

In this paragraph correction worksheet, students read an 8 line passage. Then students respond to 8 multiple choice questions regarding grammar, punctuation, and spelling errors within the paragraph.

In this color worksheet, high schoolers read where light comes from and the different colors created through a prism. Students compare light (additive color) with pigments (subtractive color). Then high schoolers complete 1 drawing, 6...

Students calculate the Balmer series. In this physics lesson, students observe hydrogen lamp spectra using spectrometers. They calculate wavelength and compare them with their theoretical calculations.

Students investigate bio-fuel. In this investigative lesson, students create bio-fuel from vegetable oil waste. Students will analyze, predict, collect and synthesize data from their experiments with bio-fuel.

Students demonstrate radioactive decay using candy corns. In this Physics lesson, students make predictions, collect data and form conclusions about patterns in radioactive decay.

Young scholars study light and see what emits photons and that light can be separated onto a spectrum.  In this energy and matter lesson students identify gases using a spectrum chart. 

A well designed clear tutorial explaining the energies involved in the Bohr model of the atom. Illustrations add to the clearly presented equations.

This activity introduces students to scientific models. The students will learn how models of the atom have changed as new evidence is gathered. The students will also learn about the current model of the atom. Each student will make a...

Resource investigates how Bohr's model of hydrogen explains atomic emission spectra.

Students build atoms of elements 1-20. The entire set can be hung from the ceiling in order of the Periodic Table to be referred to throughout the Chemistry class/unit. This is helpful when teaching bonding and patterns of the Periodic...

Discusses models of the atom developed by John Dalton, J.J. Thomson, Ernest Rutherford, Niels Bohr, and James Chadwick. Includes clear illustrations and a short comprehension exercise at the end.

How did scientists figure out the structure of atoms without looking at them? Try out different models by shooting light at the atom. Check how the prediction of the model matches the experimental results.

Presents models of the atom developed by Thomson, Rutherford, Bohr, and Schrodinger. Includes successes and failures of each, illustrations, and detailed descriptions. Also discusses Dirac's model of the atom and introduces quantum...

Learn about the models of the atom that have been proposed throughout history. Presents Democritus, John Dalton, J.J. Thomson, Ernest Rutherford, Niels Bohr, and the modern theory of the atom. Sections are accompanied by journal...

In this activity, students will explore several different models of the hydrogen atom and compare and contrast them using an online java applet.

How Bohr's model of hydrogen explains atomic emission spectra.

Learn about atomic structure and the multiple theories of atomic structure in this simulation.

An explanation using quantum mechanics to describe the atom.

Students create models of atoms then compare the various aspects of the atoms including; relative size, charge, positions of subatomic particles, and identity of the atom based on proton, neutron, and electrons with the class.
