Concord Consortium: Making and Breaking Bonds
Read the Fine Print
Rating
0.0 stars

In this interactive activity, learners explore factors that cause atoms to form (or break) bonds with each other. The first simulation depicts a box containing 12 identical atoms. Using a slider to add heat, students can see the influence of temperature on formation of diatomic bonds. Simulations #2 and #3 introduce learners to reactions involving two types of atoms. Which atom forms a diatomic molecule more easily, and why? The activity concludes as students explore paired atoms (molecules). In this simulation they compare the amount of energy needed to break the molecular bonds to the energy needed to form the bonds.

Concord Consortium: Probability Clouds
Read the Fine Print
Rating
0.0 stars

In this interactive activity, learners build computer models of atoms by adding or removing electrons, protons, and neutrons. It presents the orbital model of an atom: a nucleus consisting of protons and neutrons with electrons surrounding it in regions of high probability called orbitals. Guided tasks are provided, such as constructing a lithium atom and a carbon-12 atom in the fewest possible steps. The activity concludes with a model for building a charged hydrogen atom (an ion). Within each task, students take snapshots of their work product and answer probative questions.

Electrolytic Reduction for Artifact Conservation
Unrestricted Use
CC BY
Rating
0.0 stars

This video resource is presented as a real-world application of chemistry in the field of archaeology. Conservator, Nichole Doub, walks through the process of electrolytic reduction and how it is used to conserve archaeologically recovered artifacts. Use to support Maryland/NGSS for grades 5, MS, and HS. For 5-PS1-1, pair with the Exploratorium's "Copper Caper" activity for a similar reaction which can be conducted safely in the classroom--have students watch the video and discuss why the spoon formed tarnish and why the tarnish was not visible as particles moved from the spoon to the sacrificial anode. For MS-PS1-1, pair with the Exploratorium's "Indicating Electrolysis" activity and have the students explain the charges of oxygen/hydrogen and compare/contrast those with the silver and sulfur in the tarnish. Have students research silver sulfide (the usual tarnish found on silver artifacts) and model a single molecule of it before and after electrolysis. For HS-PS1-1 have students research silver sulfide and model a molecule of it prior to watching the video and predict what will happen when the positive or negative charges change. For HS-PS2-6, have students postulate why, historically, coins were made from silver and gold (with reference to their chemical reactions), then have students design a coin and specify a different metal to make it out of, explaining why the atomic properties of that metal make it appropriate for use in currency.

Gumdrop Atoms
Read the Fine Print
Educational Use
Rating
0.0 stars

Students use gumdrops and toothpicks to make lithium atom models. Using these models, they investigate the makeup of atoms, including their relative size. Students are then asked to form molecules out of atoms, much in the same way they constructed atoms out of the particles that atoms are made of. Students also practice adding and subtracting electrons from an atom and determining the overall charges on atoms.

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water. This lab asks learners to record measurements and make calculations related to volume, diameter, area, and height. Learners also convert meters into nanometers. Includes teacher and student worksheets but lacks in depth procedure information. The author suggests educators search the web for more complete lab instructions.

This activity seeks to have students model the process of science by recording quantitative and qualitative attributes of reactants and products in three separate experiments with the purpose of examining the relationship between the original reactant(s) to the final product(s). Students record the mass and volume of reactants and products and independently calculate mathematical relationships between the reactant(s) and product(s). They also record their observations of any physical changes that occur.

Mixtures and Solutions

Educational Use
Rating
0.0 stars

Through three lessons and their four associated activities, students are introduced to concepts related to mixtures and solutions. Students consider how mixtures and solutions and atoms and molecules can influence new technologies developed by engineers. To begin, students explore the fundamentals of atoms and their structures. The building blocks of matter (protons, electrons, neutrons) are covered in detail. The next lesson examines the properties of elements and the periodic table one method of organization for the elements. The concepts of physical and chemical properties are also reviewed. Finally, the last lesson introduces the properties of mixtures and solutions. A comparison of different mixtures and solutions, their properties and their separation qualities are explored.
