This interactive activity helps learners visualize the role of electrons in the formation of ionic and covalent chemical bonds. Students explore different types of chemical bonds by first viewing a single hydrogen atom in an electric field model. Next, students use sliders to change the electronegativity between two atoms -- a model to help them understand why some atoms are attracted. Finally, students experiment in making their own models: non-polar covalent, polar covalent, and ionic bonds.

This 90-minute activity features six interactive molecular models to explore the relationships among voltage, current, and resistance. Students start at the atomic level to explore how voltage and resistance affect the flow of electrons. Next, they use a model to investigate how temperature can affect conductivity and resistivity. Finally, they explore how electricity can be converted to other forms of energy. The activity was developed for introductory physics courses, but the first half could be appropriate for physical science and Physics First. The formula for Ohm's Law is introduced, but calculations are not required.

This concept-building activity contains a set of sequenced simulations for investigating how atoms can be excited to give off radiation (photons). Students explore 3-dimensional models to learn about the nature of photons as "wave packets" of light, how photons are emitted, and the connection between an atom's electron configuration and how it absorbs light. Registered users are able to use free data capture tools to take snapshots, drag thumbnails, and submit responses.

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.

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.

Elementary grade students investigate heat transfer in this activity to design and build a solar oven, then test its effectiveness using a temperature sensor. It blends the hands-on activity with digital graphing tools that allow kids to easily plot and share their data. Included in the package are illustrated procedures and extension activities. Note Requirements: This lesson requires a "VernierGo" temperature sensing device, available for ~ $40.

This is a Google Slides that is to be used with the book Everything You Need to Ace Computer Science and Coding in One Big Fat Notebook, Unit 5, Chapter 15.

The lessons included in the attached Google Slides incorporate standards from Computer Science, Math, Language Arts, and Physical Education. The lessons all focus on conditional statements (IF, THEN, ELSE) and can easily be adapted to fit any grade from kindergarten to fifth grade. 

The heat conductivity of a solid material defines how fast heat will flow through it. You can probably think of several everyday examples of materials with high (fast) conductivity or low (slow) conductivity. This model illustrates the effect of different conductivities by placing different materials between a hot and a cold object and graphing the changing temperatures.

The rate of heat flow between two objects is proportional to their difference in temperature. One experiences this every day, with stoves, outdoor weather and touching things. If you touch something that's the same temperature as your hand, there's no heat flow at all. This model allows you to adjust the temperature difference between two objects and observe the graph of heat flow.

Heat flows through solids at rates measured by their conductivity. The rate of heat flow is also proportional to the thickness of the material. This model compares the rate of heat transfer between two objects when they are separated by walls of different thickness.

Experiment with conductivity in metals, plastics and photoconductors. See why metals conduct and plastics don't, and why some materials conduct only when you shine a flashlight on them.

To review types of conflict in fiction text, students will create a storyboard highlighting each of the types of conflict. Students will develop a short story involving a form of literary conflict. Students will write and illustrate the story within the designated boxes of the storyboard. Students will create a total of six storyboards for each of the types of conflict - Individual vs. Individual, Individual vs. Self, Individual vs. Nature, Individual vs. Supernatural, Individual vs. Technology, and Individual vs. Society.

This video is part of the Continue to Know with WHRO TV series. Watch Kelly Sowden teach about conflict and resolution.

Explore how populations change over time in a NetLogo model of sheep and grass. Experiment with the initial number of sheep, the sheep birthrate, the amount of energy sheep gain from the grass, and the rate at which the grass re-grows. Remove sheep that have a particular trait (better teeth) from the population, then watch what happens to the sheep teeth trait in the population as a whole. Consider conflicting selection pressures to make predictions about other instances of natural selection.

The teacher will review the six types of conflict found in literature (individual vs. individual, individual vs. technology, individual vs. nature, individual vs. self, individual vs. supernatural, and individual vs. society). Students will create conflict in the news presentations identifying the six types of conflict. Students will use current newspapers and credible online news sources to identify and correctly label current examples of conflict today.

Students will color code each set of triangles to tell which shortcut, if any, can prove the triangles congruent. Shortcuts included are SSS, SAS, ASA, AAS, and HL. Students can complete this digitally or it can be printed out and used as a worksheet.
