Students will: determine the number of protons, neutrons, and electrons for a …
Students will: determine the number of protons, neutrons, and electrons for a given element by using the periodic table; construct and draw models and diagrams of atoms; use the concept of the stable octet to predict simple molecular formulas; and distinguish between elements and compounds.
This lesson introduces students to scientific models. The students will learn how …
This lesson introduces students to scientific models. The students will learn how models of the atom have changed as new evidence is gathered. The students will also learn about the current model of the atom. Each student will make a model of an atom of a different element.

This app for iPad devices is a fully interactive atomistic simulation that shows the motions of atoms as they attract, repel, and collide with one another. With the tap or swipe of a finger, students can add, delete, or highlight molecules, as well as increase/decrease temperature, pressure, or volume and explore the states of matter. An associated simulation, Salts, allows students to manipulate atoms and ions to join to form crystals.
Sample Learning Goals Describe and draw models for common static electricity concepts …
Sample Learning Goals Describe and draw models for common static electricity concepts (transfer of charge, induction, attraction, repulsion, and grounding) Make predictions about force at a distance for various configurations of charge
This illustration shows a close-up of a section of the band of …
This illustration shows a close-up of a section of the band of stability and shows the types of decay a radioactive isotope might undergo to become stable.
In this tutorial students will learn about static electricity. Students will also …
In this tutorial students will learn about static electricity. Students will also be able to explain what happens when neutral, positively charged, and/or negatively charged objects come into contact with one another.
In this activity, students will wear "tags" to identify themselves as common …
In this activity, students will wear "tags" to identify themselves as common ions and find a classmate that they can "bond" with. Students will record information in a table, including the formula and the name of the compound that is created during the bonding.
In this activity, students determine the number of valence electrons for a …
In this activity, students determine the number of valence electrons for a variety of elements. They will then create Lewis structures (using pieces of cereal or small candies as electrons) to show what happens when two of the elements combine via ionic bonding.
Students make observations of a ball bouncing off a hard surface one …
Students make observations of a ball bouncing off a hard surface one time or sequentially for several trials. From these observations students will then describe and explain the motion of the ball.
This demonstration involves properties of carbon dioxide and hydrogen. A video is …
This demonstration involves properties of carbon dioxide and hydrogen. A video is included in addition to the written instructions. It touches on a number of areas of chemistry: density of gases, solubility of gases, sublimation and combustion. Each of these areas could be explored in more detail, depending on the level of the group.
In this lesson, students will learn that forces can change the speed …
In this lesson, students will learn that forces can change the speed or direction of motion. Students will observe what happens to a toy car as it moves down a ramp and then encounters "speed bumps" that are added at different lengths away from the ramp. Students will also add a clay figure to the top of the cars to see what effect the ramp and "speed bumps" will have on the figure.
The bunny has forgotten to deliver an egg. Design a structure for …
The bunny has forgotten to deliver an egg. Design a structure for the bunny to safely deliver the missing egg without the bunny being seen (drop from above) and without the egg breaking.
Students will be given a variety of materials. They are tasked with building a structure (ie: parachute, cage, etc.) to safely drop their egg to the floor without it breaking.
Students will be able to:make and document scientific observations in order to …
Students will be able to:make and document scientific observations in order to compare the effects of different materials on an object's movement using Sphero Bolt coding robots.
Students will be able to:Follow experiment directions to create a mixture that …
Students will be able to:Follow experiment directions to create a mixture that will eventually create "snow" while also recording steps and data on paper, as well as using Stop Motion Animation to document visually their progress through the activity.
Students will be able to: carry out an investigation by designing and …
Students will be able to: carry out an investigation by designing and building a roller coaster to understand how force, motion, gravity, friction, and changes in mass affect the motion of various size/weight balls.
