Take an in-depth look at the historical events in Hiroshima and Nagasaki in this 69-slide PowerPoint. Photos, facts, and transcripts are outlined in this presentation in order to answer the stated essential question in slide 2: "What...

Bold boxes present parts of the periodic table, with some of the contents conveniently missing. Beginning chemists fill in the blanks, which may include the atomic number, atomic mass, atomic symbol, or element name. Beneath each box...

In this atomic weight and ions worksheet, learners answer questions about isotopes of atoms and how it relates to atomic weight. They also write out oxidation or reduction reactions for given atoms undergoing loss or gain of electrons.

While the use of the atomic bomb was the definitive end of World War II, the terrible weapons left new questions. Young scholars use primary sources and analytical worksheets to consider the implications of the fateful decision. Then,...

In this atomic theory instructional activity, high schoolers complete a paragraph describing the development of the atomic theory by filling in the blank with 21 terms.

Sometimes modeling is the best approach to working with microscopic particles. A lab investigation models a fictional element using pasta. The setup uses three different pasta types to represent three different isotopes. Learners...

For this atomic trend worksheet, students answer questions about trends in the periodic table such as ionization energy, atomic radii and electronegativity. They are given tables of elements and ions and they must identify which ones...

In this chemistry worksheet, students examine the periodic table and how it is used in the context of interpreting compounds and their structure.

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

The end of World War II saw major events that would forever change the global landscape and international relations. Using a fantastic PowerPoint presentation and several primary source documents, your learners will discuss the...

This compact collection of slides explains the history and use of the mole unit. Relative atomic mass, as John Dalton understood it, is explained. Avogadro's number is also introduced. The mole, or the unit for the amount of a substance,...

Prepare your chemistry charges for stoichiometry with this PowerPoint. The objective is to be able to calculate molar mass for different compounds. Beginning with the foundational definition of moles and moving through atomic and...

In this online interactive atomic structure crossword puzzle activity, students use 5 clues to find the appropriate answers to complete the word puzzle.

In preparation for an introduction to chemistry exam, play Chemistry Jeopardy with your class. The categories include molar relationships, phases of matter, atomic structure, chemical nomenclature, and scientific investigation. If the...

Students develop an understanding of the mole and molar masses of elements. In this mole lesson plan, students use beans to find their relative masses and draw parallels to the atomic masses of elements. Students work in teams and each...

Students explore atomic structure including protons and electrons, in order to proceed with lessons on static electricity.

In this emission spectra worksheet, students use a spectroscope to observe three types of spectra. These include continuous spectrum, emission spectrum and absorption spectrum.

In this atomic structure worksheet, students use the periodic table to complete a chart for 11 elements/ions in terms of atomic number, number of protons, neutrons and electrons.

Advanced lab apprentices prepare zinc and copper solutions to which they will compare the same minerals from a multivitamin. Using absorption spectroscopy, they analyze the contents of the multivitamin for concentration. This lab can be...

A full-fledged practice final prepares pupils for their general chemistry final exam. If they complete these 57 multiple-choice questions correctly, they will be well-prepared. Note: even though the questions are multiple-choice, there...

In this chemistry worksheet, students determine which compound is the most acidic in each multiple choice question. Then they determine what the major product would be in each of the reactions stated on the sheet.

At the end of a general physics course focused on light and electricity, you can administer this exam. Concepts covered include electromagnetism, circuits, induction, light rays, lenses and mirrors, characteristics of light, electron...

A lot has happened in the month of October in the past 100 years or so. Kids fill in the blank for 31 events, each of which occurred on a day in October. Each event can be found in a New York Times article from the past 100+ years....

Students understand the evolution of the atomic model from Ancient Greece to the present. They then choose one of the options as a project using class time to do research and to be creative.
