This lesson combines a powerpoint lecture and a reading activity to teach students about the theory and structure of atoms.
Starting from atoms, see how many molecules you can build. Collect your molecules and see them in 3D!
Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Then play a game to test your ideas!
Students will explore the periodic table by using clues from Mendeleev to decipher which element each room is made of. A basic understanding of the periodic table is needed including atomic number, atomic weight, periods, rows, and groups. An embedded periodic table is included to help students solve the riddles. The element's symbol is the password that unlocks each of the 12 rooms.
In this activity, students will learn the location of the following categories on the periodic table while creating their own version including a key.Categories Included:Alkali MetalsAlkaline Earth MetalsHalogensNoble GasesMetalsNonmetalsMetalloidsTransition MetalsInner Transition MetalsThe Soft Chalk Activity includes interactive checks throughout and includes information on valence electrons and determining groups and periods for elements.This activity also includes a formative assessment that students could take when they are done.
This interactive, scaffolded activity allows students to build an atom within the framework of a newer orbital model. It opens with an explanation of why the Bohr model is incorrect and provides an analogy for understanding orbitals that is simple enough for grades 8-9. As the activity progresses, students build atoms and ions by adding or removing protons, electrons, and neutrons. As changes are made, the model displays the atomic number, net charge, and isotope symbol. Try the "Add an Electron" page to build electrons around a boron nucleus and see how electrons align from lower-to-higher energy. This item is part of the Concord Consortium, a nonprofit research and development organization dedicated to transforming education through technology. The Concord Consortium develops deeply digital learning innovations for science, mathematics, and engineering. The models are all freely accessible.

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.

The High School Integrated Conceptual Science Program (ICSP) is a NGSS-aligned curriculum that utilizes the conceptual progressions model for bundling of the NGSS, High School Conceptual Model Course 1 and strategies from Ambitious Science Teaching (AST) to focus on teaching practices needed to engage students in science discourse and learning. Course 1 is the High School Integrated Physics and Chemsitry Course. The goal of these units is to encourage students to continue in STEM by providing engaging and aligned curriculum. The focus of this year long course is on the first year of high school (freshman). While the course is designed to be taught as a collection of the units, each unit could be taught as a separate unit in a science course. A video about the new course shared its unique approach to learning and teaching. Wenatchee School District, one of the participating districts, wanted a way to share the program with the community. https://youtu.be/9AGk19YUi2oCourse 1 of the ICSP development was funded by Northwest Earth and Space Sciences Pipeline (NESSP) which is funded through the NASA Science Mission Directorate and housed with Washington NASA Space Grant Consortium at the University of Washington.
This is an interactive created with H5P to provide practice identifying compounds as either ionic or covalent.
Have you ever passed a pond or swamp and seen bugs walking on the water? Find out how they do it in this Smithsonian Lightning Lesson.
Students measure the relative intensity of a magnetic field as a function of distance. They place a permanent magnet selected distances from a compass, measure the deflection, and use the gathered data to compute the relative magnetic field strength. Based on their findings, students create mathematical models and use the models to calculate the field strength at the edge of the magnet. They use the periodic table to predict magnetism. Finally, students create posters to communicate the details their findings. This activity guides students to think more deeply about magnetism and the modeling of fields while practicing data collection and analysis. An equations handout and two grading rubrics are provided.
In this lesson, students will learn about the history behind the atomic model and learn how to draw a Bohr model. To draw the models, cards are provided with examples for students to draw. Students can use the PhET Simulation: Build an Atom to check their answers.
The Integrated Conceptual Science Program Course 1 Integrated Physics and Chemistry is a three dimensional course based on the Conceptual Progression Model of the Next Generation Science Standards. It is designed to be used as part of a three course program that addresses all high school science performance expectations. Course 1 is designed for ninth grade students.
This resource includes the teacher materials, supporting documents, and short videos to support teachers in using the materials.
The Courses were designed using the Ambitious Science Teaching (AST) framework. It is strongly encouraged that before using these materials that you be familiar with AST. We suggest that you watch the AST Overview short video found here: https://datapuzzles.org/ambitious-science-teaching and explore this Google Slide deck that contains many resources designed to further your understanding of AST: https://docs.google.com/presentation/d/1WOUVmlm636_7i2l0GYa9JkX1TCK3NMdySfpxKN7IM7A/edit?usp=sharing
Our Patterns Chemistry development team of teacher leaders has been working hard through the spring and summer of 2020 to develop distance learning versions of the Patterns Chemistry units. Between March and May they released the below Distance Learning versions of units 4, 5 and 6, as well as paper packets that can be printed for students who do not have access to technology at home. Below are the distance learning version of units 1 and unit 2. The distance learning units can be used in either a fully online or hybrid school model. A Distance Learning version of Unit 3 will be released by the end of September. For schools reopening fully in person, scroll down to see the original Patterns Chemistry unit plans.
Students will synthesis gold and silver particles and compare the UV spectra to determine the size of the nanoparticles.
