NATIONAL SCIENCE STANDARDS (GRADES K-4):

Senses

• Properties of Objects and Materials - Objects have many observable properties, including size, weight, shape, color, temperature, and the ability to react with other substances.

What Are We Looking At?

• Positions and Motions of Objects - The position of an object can be described by locating it relative to another object or the background.

• Properties of Earth Materials Soils have properties of color and texture, capacity to retain water and ability to support the growth of may kinds of plants, including those in our food supply.

Bumpy, Wrinkled, Smooth?

• Properties of Earth Materials - Soils have properties of color and texture, capacity to retain water and ability to support the growth of may kinds of plants, including those in our food supply.
• Properties of Objects and Materials - Objects are made of one or more materials, such as paper, wood, and metal. Objects can be described by the properties of the materials from which they are made, and those properties can be used to separate or sort a group of objects or materials.

Color as Light

• Light, Heat, Electricity, and Magnetism - Light travels in a straight line until it strikes an object. Light can be reflected by a mirror, refracted by a lens, or absorbed by an object.

• The Characteristics of Organisms - Organisms have basic needs. For example, animals need air, water, and food; plants require air, water, nutrients, and light.
• Organisms can survive only in environments in which their needs are met. The world has many different environments, and distinct environments support the life of different types of organisms.
• Organisms and their environments - All animals depend on plants. Some animals eat plants for food. Other animals eat animals that eat the plants.
• Organisms and their Environments - An organismâs patterns of behavior are related to the nature of that organism's environment, including the kinds and numbers of other organisms present, the availability of food and resources, and the physical characteristics of the environment. When the environment changes, some plants and animals survive and reproduce, and others die or move to new locations.

AAAS BENCHMARKS FOR SCIENCE LITERACY

Senses

• 1B (K-2) People can often learn about things around them just b observing those things carefully, but sometimes they can learn more by doing something to the things and noting what happens.
• 1B (K-2) describing things as accurately as possible is important in science because it enables people to compare their observations to those of others.
• 1C (K-2) Everybody can do science and invent things and ideas.
• 1C (K-2) In doing science, it is often helpful to work with a team and to share findings with others. All team members should reach their own individual conclusions, however, about what the findings mean.

What Are We Looking At?

• 2A (K-2) Circles, squares, triangles, and other shapes can be found in things in nature and in things that people build.
• 2A (K-2) Patterns can be made by putting different shapes together or taking them apart.
• 2C (K-2) Numbers and shapes can be used to tell about things.
• 6D (K-2) People use their senses to find out about their surroundings and themselves. Different senses give different information. Sometimes a person can get different information by moving closer to it or further away from it.

• 2A (K-2) Circles, squares, triangles, and other shapes can be found in things in nature and in things that people build.
• 2A (K-2) Patterns can be made by putting different shapes together or taking them apart.
• 2C (K-2) Numbers and shapes can be used to tell about things.
• 4C (K-2) chunks of rocks come in many sizes and shapes, from boulders to grains of sand and even smaller.
• 9B (K-2) Similar patterns may show up in many places in nature and in the things people make.
• 9C (K-2) Shapes such as circles, squares, and triangles can be used to describe many things that can be seen.

Texture : Bumpy, Wrinkled, Smooth?

• 4D (K-2) Objects can be described in terms of the materials they are made of (clay, cloth, paper, etc.) and their physical properties (color, size, shape, weight, texture, flexibility, etc.)

Color as Light

• 1B (K-2) People can often learn about things around them just b observing those things carefully, but sometimes they can learn more by doing something to the things and noting what happens.
• 9A (K-2) simple graphs can help to tell about observations

Locating Echo

• 5A (K-2) Plants and animals have features that help then live in different environments.
• 5A (K-2) Stories sometimes give plants and animals attributes they really do not have.
• 5D (K-2) Animals eat plants and other animals for food and may also use plants (or even other animals) for shelter or nesting.
• 5D (K-2) Living things are found almost everywhere in the world. There are somewhat different kinds in different places.
• 5E (K-2) Plants and animals both need to take in water, and animals need to take in food. In addition, plants need light.
• 5F (K-2) Different plants and animals have external features that help then thrive in different kinds of places.
