National Science Content Standards Alignment<br />

<strong>The</strong> National Science Standards serve as a guide for the science standards of each state. In order to make this<br />

guide as applicable as possible, we have included the National Science Standards that we feel are appropriate<br />

for the content contained in the <strong>Science<strong>Makers</strong></strong> DVD <strong>Toolkit</strong>. Since the <strong>Science<strong>Makers</strong></strong> program contains such<br />

a diverse body of knowledge, not every science standard will apply to every Spotlight or activity. <strong>The</strong> following<br />

is a list of standards that may apply to one or more areas of the curriculum. For the sake of clarity, individual<br />

numbers within each section have been removed, though the section labels remain intact as a reference. If you<br />

are seeking to align this curriculum with the standards in your area, this should serve as an appropriate guide.<br />

B. Physical Science - Physical science focuses on science facts, concepts, principles, theories and models<br />

that are important for all students to know, understand and use.<br />

M.B.1 Properties and changes of properties in matter<br />

• Substances react chemically in characteristic ways with other substances to form new substances (compounds)<br />

with different characteristic properties. In chemical reactions, the total mass is conserved. Substances<br />

often are placed in categories or groups if they react in similar ways; metals are an example of such<br />

a group.<br />

• Chemical elements do not break down during normal laboratory reactions involving such treatments as heating,<br />

exposure to electric current, or reaction with acids. <strong>The</strong>re are more than 100 known elements that combine<br />

in a multitude of ways to produce compounds, which account for the living and nonliving substances<br />

that we encounter.<br />

H.B.1 Structure of atoms<br />

• Matter is made of minute particles called atoms, and atoms are composed of even smaller components.<br />

<strong>The</strong>se components have measurable properties, such as mass and electrical charge. Each atom has a positively<br />

charged nucleus surrounded by negatively charged electrons. <strong>The</strong> electric force between the nucleus<br />

and electrons holds the atom together.<br />

• <strong>The</strong> atom’s nucleus is composed of protons and neutrons, which are much more massive than electrons.<br />

When an element has atoms that differ in the number of neutrons, these atoms are called different isotopes<br />

of the element.<br />

• <strong>The</strong> nuclear forces that hold the nucleus of an atom together, at nuclear distances, are usually stronger than<br />

the electric forces that would make it fl y apart. Nuclear reactions convert a fraction of the mass of interacting<br />

particles into energy, and they can release much greater amounts of energy than atomic interactions.<br />

Fission is the splitting of a large nucleus into smaller pieces. Fusion is the joining of two nuclei at extremely<br />

high temperature and pressure, and is the process responsible for the energy of the sun and other stars.<br />

• Radioactive isotopes are unstable and undergo spontaneous nuclear reactions, emitting particles and/or<br />

wavelike radiation. <strong>The</strong> decay of any one nucleus cannot be predicted, but a large group of identical nuclei<br />

decay at a predictable rate. This predictability can be used to estimate the age of materials that contain radioactive<br />

isotopes.<br />

H.B.2 Structure and properties of matter<br />

• Atoms interact with one another by transferring or sharing electrons that are furthest from the nucleus.<br />

<strong>The</strong>se outer electrons govern the chemical properties of the element.<br />
