This video will help students learn how to multiply vectors by scalars and the different algebraic properties of scalar multiplication.
This interactive game will test students' knowledge of vector-scalar multiplication with the following scenario:
An orange motorboat and a blue sailboat are racing. The sailboat can go faster but must move diagonally with the wind. The motorboat isn't as fast, but it can race straight from start to finish.
In this race, each vector represents how far the boat travels in one hour of racing.
This self-checking online assessment has 10 questions that will help students practice the skill of multiplying a vector by a scalar. There are hints available on the screen, and there is an online scratchpad that students can use to work the problems.
In this lesson, students will put a static charge on a strip of plastic by pulling it between their fingers. They will see that the plastic is attracted to their fingers. Students will be introduced to the idea that rubbing the strip with their fingers caused electrons to move from their skin to the plastic giving the plastic a negative charge and their skin a positive charge. Through these activities, students will be introduced to some of the characteristics of electrons, protons, and neutrons, which make up atoms.
Students will be able to explain, in terms of electrons and protons, why a charged object is attracted or repelled by another charged object. They will also be able to explain why a charged object can even be attracted to an uncharged object. Students will also be able to explain that the attraction between positive protons and negative electrons holds an atom together.
In this lesson, students will begin to look closely at the periodic table. They will be introduced to the basic information given for the elements in most periodic tables: the name, symbol, atomic number, and atomic mass for each element. Students will focus on the first 20 elements. They will try to correctly match cards with information about an element to each of the first 20 elements. Students will then watch several videos of some interesting chemical reactions involving some of these elements. Students will identify different atoms by the number of protons in the nucleus and realize that the number of electrons equals the number of protons in a neutral atom. They will also be able to explain the meaning of atomic number and atomic mass.
In this lesson, students will focus on the first 20 elements of the periodic table. Students will first look at a diagram and animation to understand the basic pattern of the arrangement of electrons on energy levels around an atom. Students will be given cards with information about the electrons and energy levels for each of the first 20 atoms. They will try to correctly match cards with each element.
Students will be able to interpret the information given in the periodic table to describe the arrangement of electrons on the energy levels around an atom.
In this lesson, students will look at animations and refer to the energy level models they have been using to make drawings of the process of covalent bonding. Students will consider why atoms bond to form molecules like H2 (hydrogen), H2O (water), O2 (oxygen), CH4 (methane), and CO2 (carbon dioxide).
Students will be able to explain that attraction between the protons and electrons of two atoms cause them to bond. Students will be able to draw a model of the covalent bonds between the atoms in H2 (hydrogen), H2O (water), O2 (oxygen), CH4 (methane), and CO2 (carbon dioxide).
In this lesson, students will look at animations and make drawings of the ionic bonding of sodium chloride (NaCl). Students will see that both ionic and covalent bonding start with the attractions of protons and electrons between different atoms. But in ionic bonding, electrons are transferred from one atom to the other and not shared like in covalent bonding. Students will use Styrofoam balls to make models of the ionic bonding in sodium chloride (salt).
Students will be able to explain the process of the formation of ions and ionic bonds.
Engineering is the “silent E” in STEM subject areas. While science, mathematics, and technology are often topics of content area lessons, engineering is often ignored. However, engineering is inclusive of all STEM subjects because engineers use science, mathematics, and technology to solve problems. Engineering careers are diverse, spanning many different technologies and disciplines, such as agricultural engineering, aerospace engineering, computer engineering, mechanical engineering, and chemical engineering. Each of these jobs involves a rich, highly-specialized vocabulary. In this lesson, students are introduced to the vocabulary of engineering careers by reading informational websites. After learning the terminology, they use discipline-specific vocabulary words to create poems about engineering careers.

Students use Shakespeare's Secret, a featured title on the Teachers' Choices Booklist (International Reading Association, 2006), as a springboard to the exploration of the controversy regarding the authorship of Shakespeare's works. The novel makes liberal use of the historical details surrounding William Shakespeare's life and exposes students to the possibility raised by some theorists that Edward de Vere, Earl of Oxford, was the true author of the works that have long been attributed to the Bard. Students explore the historical references in the novel and generate questions for further research. As they research these questions on suggested websites, they organize their findings with the help of the ReadWriteThink Notetaker. Then they work in small groups to create and present short dramatic skits that creatively connect the novel with the historical facts.
In this learning activity, students will pretend they have been chosen to induct Frederick Douglass and Harriet Beecher Stowe into the fictional abolitionist hall-of-fame. Their first job, however, is to design a “flyer” that advertises the inductees and the reasons for their inductions. In the spaces provided on the flyer, they will continue the narratives that highlight each inductee’s accomplishments. Secondly, they will design an abolitionist hall-of-fame medal each would receive upon their entry. Medals can include icons, symbols, color, and their names.
In this lesson, students will be introduced to the idea that water has a slightly positive charge at one end of the molecule and a slightly negative charge at the other (a polar molecule). Students view animations, make illustrations, and use their own water molecule models to develop an understanding of how the polar nature of water molecules can help explain some important characteristics of water.
Students will be able to explain, on the molecular level, what makes water a polar molecule. Students will also be able to show, in a drawing, that the polar nature of water can explain some of water’s interesting characteristics and help explain its evaporation rate compared to a less polar liquid.
In this lesson, students will observe several phenomena related to the polarity of water molecules. They will observe a demonstration of a paper clip being placed on the surface of the water. Students will place drops of water in an already-filled test tube and on the surface of a penny. They will compare the way water behaves with the less polar liquid isopropyl alcohol and will see how detergent affects water’s surface tension. Students will relate these observations to an explanation of surface tension at the molecular level.
Students will be able to explain, on the molecular level, the effects of polarity on water’s surface tension.
In this lesson, students will make a 2-D model of a salt crystal and use water molecule cut-outs to show how water dissolves salt.
