This video clip is meant to serve as a writing or discussion prompt during a unit on forces and motion. This can be used at varied grade levels, with the expectation that student responses would be more complex in higher grade levels.
Students explore Newton's first law of motion. In the associated activity, students will experiment with variable speeds and distances to see how far and how fast they can throw an egg without breaking it.
Students analyze a map of the North Polar region, test their knowledge of the Arctic, and brainstorm examples of the interconnectedness of life in this region with life around the world.
How are magnetism and electricity related? In this lesson, students will explore the relationship between magnetism and electricity, learn how to construct an electromagnet, and discover everyday uses of electromagnets. Students will create a multimedia presentation in which they will demonstrate their knowledge of electromagnetism.
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 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.
Students write balanced equations for a series of word equations. Students will also indicate the type of reaction as described.
Students will compare speeds of different objects over the same distance in order to explain how weight affects speed.
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 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 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 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 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 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 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.
Students experiment with batteries, wires, bulbs, and switches to assemble series and parallel circuits and to test for conductivity in sample items.
In this hands-on lesson, students will be able to build an electromagnet, compare and change its variables to understand its energy.
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.
In this lab activity, students will test household chemicals with litmus paper and using red-cabbage juice inidcator and use the results to classify household substances as acids or bases.
