Standard S5P1. Students will verify that an object is the sum of its parts. | |||
| a. Demonstrate that the mass of an object is equal to the sum of its parts by manipulating and measuring different objects made of various parts. | The properties of
Matter: Matter - anything that occupies a space. Mass - how much matter is in a space. Weight - the mass of an object when it is being affected by gravity. Weight can change if gravity changes but the mass of an object stays the same. Mass x Gravity = Weight Volume - how much space an object takes up. Density - is how solid an object is, the more matter in an object the more dense it is.  Physical properties - these are things that can be observed or measured. Color, length, height, width, density, solubility, distinctive markings, taste, smell, texture, sound, volume. Measuring Matter  Describing Matter  | ||
| b. Investigate how common items have parts that are too small to be seen without magnification. | Atoms - Chem4Kids Atom Builder - PBS  | ||
S5P2. Students will explain the difference between a physical change and a chemical change. | |||
| Investigate physical changes by separating mixtures and manipulating (cutting, tearing, folding) paper to demonstrate examples of physical change. | Physical
changes occur when objects undergo a change that does not change their
chemical nature. A physical change involves a change in physical properties.
Physical properties can be observed without changing the type of matter.
Examples of physical properties include: texture, shape, size, color, odor,
volume, mass, weight, and density. Physical Changes  | ||
| Recognize that the changes in state of water (water vapor/steam, liquid, ice) are due to temperature differences and are examples of physical change. | Matter
comes in three different ways called phases, they are solid, liquid, and gas.
These changes in matter are physical changes caused by a change in
temperature. Phase changes  States of Matter Chem4kids - States of Matter  Elementary Science - Matter | ||
| Investigate the properties of a substance before, during, and after a chemical reaction to find evidence of change. | Chemical
changes are changes substances undergo when they become new or different
substances. For example, the fireworks we see on the 4th of July are actually
metals such as magnesium and copper that change chemically as they light up the
night skies with their fantastic colors. To identify a chemical change look for
observable signs such as color change, bubbling and fizzing, light production,
smoke, and presence of heat. Chemical Changes click through pages to see more information  | ||
S5P3. Students will investigate the electricity, magnetism, and their relationship. | |||
| Investigate static electricity. | What is static
electricity? Basics of static electricity  Energy Story  | ||
| Determine the necessary components for completing an electric circuit. | Energy Story -
Circuits Create a circuit | ||
| Investigate common materials to determine if they are insulators or conductors of electricity. | |||
| Compare a bar magnet to an electromagnet. | Magnet
Madness Magnets and Electromagnets  Explain that stuff - This page includes information on electricity, static electricity, circuits and electromagnets | ||
