Scientific Investigation, Reasoning, and Logic
K.1 The student will demonstrate an understanding of scientific reasoning, logic, and the nature of science by planning and conducting investigations in which
a) basic characteristics or properties of objects are identified by direct observation;
b) observations are made from multiple positions to achieve different perspectives;
c) a set of objects is sequenced according to size;
d) a set of objects is separated into two groups based on a single physical characteristic;
e) nonstandard units are used to measure the length, mass, and volume of common objects;
f) observations and predictions are made for an unseen member in a sequence of objects;
g) a question is developed and predictions are made from one or more observations;
h) observations are recorded;
i) picture graphs are constructed;
j) unusual or unexpected results in an activity are recognized; and
k) objects are described both pictorially and verbally.
In order to meet this standard, it is expected that students will
K.2 The student will investigate and understand that humans have senses that allow them to seek, find, take in, and react or respond to information in order to learn about their surroundings.
Key concepts include
a) the five senses and corresponding sensing organs; and
b) sensory descriptors used to describe common objects and phenomena.

In order to meet this standard, it is expected that students will
- observe objects and describe their basic properties. These properties include color, shape (circle, triangle, square, and rectangle), size (big, little, large, small), texture (rough, smooth, hard, soft), and weight (heavy, light).
- observe an object or objects from multiple positions to achieve different perspectives. In order to accomplish this, the student should look at the object from top, bottom, front, and back, and describe what he/she sees.
- arrange a set of objects in sequence according to size.
- separate a set of objects into two groups based on a single physical characteristic, including color, shape, size, texture, and weight.
- measure common objects with nonstandard units. Examples of nonstandard units include hands, pennies, and paper clips for determining length; holding and comparing two different objects for determining mass; and liquids put in drinking cups for determining volume.
- predict an unseen member in a sequence of objects to complete a pattern
- develop a question from one or more observations about the natural world
- make a prediction based on observations.
- record observations using pictures.
- construct picture graphs using 10 or fewer units.
- identify unusual or unexpected results in an activity.
- describe objects both pictorially and verbally.

Standard K.1 Strand: Scientific Investigation, Reasoning, and Logic
In order to meet this standard it is expected that students will
- identify and describe the five senses: taste, touch, smell, hearing, and sight.
- match each sensing organ (eye, ear, nose, tongue, and skin) with its associated sense.
- match sensory descriptors with the senses (taste: sweet, sour, bitter, salty; touch: rough, smooth, hard, soft, cold, warm, hot; hearing: loud, soft, high, low; sight: bright, dull, color, black, white; smell: strong, faint, bad, and good.)
