Build learning by breaking atoms! Young scientists study the way energy changes with a hands-on activity. As they roll steel marbles down a ramp, learners test the hypothesis that kinetic energy does not go away with friction...

Uranium 235 has a half-life of over 700 million years and is the fuel used in the atomic bomb dropped on Hiroshima, Japan. Pupils see the half-lives and decay rates of Carbon-14 and Uranium-238. They also take measurements of these two...

First, beginning chemists assemble a large periodic table of elements. Then, they play a game in which they roll dice, move a marker along the elements, and collect pennies according to the number of valence electrons of the element that...

Referring to the periodic table of elements, nuclear physics learners determine the resulting elements of alpha and beta decay. Answers are given in atomic notation, showing the atomic symbol, mass, atomic number, and emission particles....

Eighth graders explain the development of the atomic model over time. In this chemistry lesson, 8th graders research about the scientists who made a contribution to the atomic theory. They create a three-dimensional model based on their...

Students research and discuss issues surrounding the atomic bomb and the concerns it raised and the consequences of dropping the atomic bombs on Japan. A variety of sample questions are provided to engage discussion.

Students comprehend the Development and control of Nuclear Energy. They analyze the historical significance of the atomic age through use of primary documents. Students examines nuclear energy from the perspective of physical sciences.

Um may be the atomic symbol for confusion, but it won't be needed in this lesson. Scholars rotate through seven stations completing experiments, hands-on activities, writing exercises, and analysis. Stations include material on...

Students investigate energy sources by examining photographs.  In this atomic energy lesson,  students identify and describe various pictures and how atomic energy is used in them.  Students create a presentation...

Students read and discuss an article about carbon dating, then participate in a hands-on lab to discover how carbon dating works. Students also write a letter to a friend explaining the process, and how archeologists use the process to...

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

In this models of atoms and isotopes worksheet, students use marshmallow of different colors to represent the protons, neutrons and electrons in an atom. Students make models of the 3 isotopes of hydrogen. They draw a diagram of each and...

Students observe and/or conduct five experiments which address the Bernoulli Effect. In this conceptual lesson based on the Bernoulli Effect, the students construct atomizers, and make concrete observations and inferences in connection...

Students study the particles of which atoms are made. They define the electron, proton, and neutron and their attributes.

For this periodic table worksheet, students write the chemical symbols for the given elements, compare atomic number and mass number, and describe the importance of valence electrons in the organization of the periodic table. This...

In this atoms learning exercise, students circle the term in parentheses that makes the 20 statements correct. The statements review the parts of an atom, isotopes, and basic matter principles.

Young scholars study the stages of development of an unknown organism. In this zebrafish instructional activity, students examine and collect data as they use microscopes to view a zebrafish embryo.

For this radioactivity worksheet, students write the mass number and atomic number for the missing element in the reactions. Students identify the isotope that is more stable and determine the half-life of the isotope. This worksheet has...

Super detailed, this lesson will educate physical science learners about the flow of electrons. Begin by reviewing potential and kinetic energy with a moving pendulum, and then get them online to observe interactive websites about...

Students critically investigate the issues surrounding the dropping of atomic bombs on Japan. They conclude if dropping the bombs was a correct decision or not and support their conclusions with documentation. Students tie in atomic...

Students recognize that some changes to matter are reversible and some are not.  In this matter lesson, students experiment a physical and chemical change. Students record experiment results in their science journals. Students act...

Students experiment to find which liquids are more dense.  In this density and mass lesson, students predict and then test objects to observe and measure their density. students observe which items sink and float. Students complete...

Students experiment with solids and liquids. In this mixtures of matter lesson, students combine matter to form solutions. Students hypothesize, test, and analyze the data to draw conclusions. The lesson can be extended by having...

Learners study the difference between types of ionizing radiation and how elements are transmuted. They determine that radiation is normal and surrounds us. They calculate the amounts of alpha, beta and gamma radiation emitted from a...
