"Up and Atom" is a mini-unit introducing middle-schoolers to the wonders of elements. Participants draw atom models, examine the periodic table, compare samples of metals to nonmetals, identify unknown elements, and more! The beginning...

If you are willing to sort through this outline and overlook the portions relating to inaccessible videos, you will find a wealth of support for your introductory chemistry unit. Narrative is presented to help you help learners navigate...

Students investigate the structure of the atom and its composition. For this atom structure lesson, students find the area of cut out circles and drop pens into the circles. They count the number of marks in the circles and relate their...

In this moles worksheet, students convert measurements of moles to mass, measurements of mass to moles, measurements of moles to atoms or molecules and measurements of atoms or molecules to moles.

Fifth graders investigate atoms. In this atom lesson plan, 5th graders investigate the parts of an atom. Students explore atom numbers and determine the number of electrons is in each atom.

Middle schoolers perform varied activities as part of a layered curriculum unit: They write and perform a skit that outlines the evolution of the model of the atom. The script is submitted to the teacher for review before performance.

Students practice drawing the atomic structure of several different elements. They complete critical thinking questions about atomic structure and compare the atomic mass units for different ions and isotopes of an element.

Fifth graders relate the elements in the human body to those produced during a supernova. In this space science and chemistry lesson, 5th graders listen to a lecture and view visuals about the big bang. They relate the production of...

Explore the connection of surface area to bonding within atoms. Learners complete lab investigations to model changing surface area with different sizes and concentrations of atoms. A flour fireball demonstration follows the labs to...

Many people confuse atomic mass and atomic numbers. The sixth of seven lessons in a unit requires scholars to find the weight of different groups of pennies. Then, they must solve how many of each type of penny exists in a closed system...

Students create an atomic model using a computer program. In this technology instructional activity, students identify the difference between radius and diameter. They create circular patterns and spheres based on certain specifications.

In this chemistry worksheet, students respond to several multiple choice questions relating to bonding and acid-bases. They also identify the various types of bases and how they differ from each other.

In this chemistry worksheet, students write how many chiral C's are in each of the compounds listed. Then they draw the Fischer projections for all stereo isomers in 5 and in 6. Students also match the correct Fischer projection to each...

Make your lesson on radioactive decay pop with this lab exercise. Using popcorn kernels spread over a tabletop, participants pick up all of those that point toward the back of the room, that is, those that represent decayed atoms. As the...

Students explore the concent of using the mole to solve problems related to counts small particles of matter. Students work individually and in groups to complete conversions of substances from moles to matter.

Students interpret basic chemical formulas. When class begins, students interpret a "chemical formula" for fruit salad. After they interpret the recipe, students use the same strategies to identify chemical formulas. They evaluate the...

High schoolers write electron configuration of elements using atomic numbers and they identify valence electrons. In this electrons lesson plan, students observe a demonstration showing the space-filling property of an electron. They...

Students figure the number of half-lives since the sample solidified, and therefore the "age" of the sample rocks.

Students examine the concepts of isotopes and atoms.  In this powerpoint lesson, students see the balance in numbers  of protons, neutrons, and electrons create isotopes and ions of certain atoms.

Students explore what radioactive decay is and are able to relate it to the concept of half-life. They are given 100 green beads that represent radioactive atoms and 100 white beads that represent stable, non-radioactive daughter atoms....

Pupils explore the concepts of energy transformation and conversion. They engage in Internet and hands-on activities. Students visit the Atoms Family Website and complete a Building a Better Pyramid activity by adding insulation to...

Students investigate the atom and how it is formed. They conduct research using a variety of resources and then construct a model of the atom. Then students have class discussion. The lesson includes background information for the...

Students consider the causes of density at a microscopic level. They then discover that one cause of density has to do with how many protons and neutrons the material contains.

Students determine what plasma is and why the sun is made up of plasma. They recognize situations where plasmas are found in nature and made by man. They discuss why the sun is a huge ball of plasma and if there are different levels of...
