1 Explain and use skills necessary to conduct scientific inquiry.

a Form hypotheses and predict outcomes of problems to be investigated. (DOK 3)

b Use the senses and simple tools to gather qualitative information about objects or events (size, shape, color, texture, sound, position, change). (DOK 1)

c Demonstrate the accurate use of simple tools to gather and compare information (DOK 1)

c1 Tools (English rulers [to the nearest eighth of an inch], metric rulers [to the nearest centimeter], thermometers, scales, hand lenses, microscopes, balances, clocks, calculators, anemometers, rain gauges)

c2 Types of data (height, mass/weight, temperature, length, distance, volume, area, perimeter)

d Use simple sketches, diagrams, tables, charts, and writing to draw conclusions and communicate data results. (DOK 2)

e Interpret and describe patterns of data using drawings, diagrams, charts, tables, graphs, and maps. (DOK 2)

f Explain why scientists and engineers often work in teams with different individuals doing different things that contribute to the results. (DOK 2)

g Draw conclusions about important steps (e.g., making observations, asking questions, trying to solve a problem, etc.) that led to inventions and discoveries. (DOK 3)

(DOK 3)

2 Use the properties of objects and materials, position and motion of objects, and transfer of energy to develop an understanding of physical science concepts.

a Recognize that materials may be composed of parts that are too small to be seen without magnification. (DOK 1)

b Distinguish between physical and chemical changes and between objects composed of a single substance from those composed of more than one substance. (DOK 2)

c Determine the causes and effects of forces on motion. (DOK 2)

c1 Force exerted over a distance causes work to be done and that the result (work) is the product of force and distance

c2 Friction on moving objects and actions that increase or decrease friction

c3 Momentum and inertia

d Explain how energy flowing through an electrical circuit can be converted from electrical energy to light, sound, or heat energy. (DOK1)

d1 Parts of an electric circuit and resulting actions when circuits are opened or closed

d2 Construction and uses of electromagnets

d3 Energy transferred through an electrical circuit to a bulb or bell to its surroundings as light, sound, and heat (thermal) energy

5 Formulate and analyze data. Evaluate inferences and predictions.

a Draw, label, and interpret bar graphs, line graphs, and stem-and-leaf plots. (DOK 2)

b1 Find and interpret the mode, median, and range of a set of data. (DOK 1)

c Compare data and interpret quantities represented on tables and graphs including line graphs, bar graphs, frequency tables, and stem-and-leaf plots to make predictions and solve problems based on the information. (DOK 3)
