Grade 2: Air and Weather Unit

Overview

The Air and Weather unit is a Full Option Science System (FOSS) kit created by the Lawrence Hall of Science at the University of California, Berkeley. It is published by Delta Education. The Air and Weather kit involves students in monitoring weather. They explore properties of air using plastic syringes and tubes to find that air takes up space and builds up pressure when compressed. Students construct devices that use air to function-parachutes, propellers, balloon rockets, gliders, pinwheels, streamers, wind socks, kites, and whirligigs.

Building Successful Foundations in Science - Elementary science integrates and organizes student scientific knowledge through a foundation made up of 'Bricks" of Big Ideas put together with the "Mortar" of Unifying Concepts.

 

Enduring Understandings - important ideas that students should carry with them years beyond the instruction received this year.

Scientific Process

  • A scientific vocabulary is needed to communicate about the scientific procedure.

  • A hypothesis is a testable prediction as to the outcome of a scientific investigation.

  • A well designed investigation involves the use of a written plan that identifies the materials to be used, the procedure to follow, and the variables. A plan needs to be followed to make sure all steps in an investigation are completed. Scientists use many tools when conducting an investigation.

  • Complete data makes it possible to explain the results of an investigation and compare it with the prediction.

  • When data is analyzed, the results can be communicated in a variety of ways.

  • A written plan must be followed in the correct sequence to make sure it is done the same way each time. (Replication of results.)

  • An investigation should be done more than once to make sure data is accurate.

  • Data is only as reliable as the people conducting the experiment. Many tools are available to help gather data. Errors can be determined by comparing data with another student or by repeating the investigation.

Movement

  • Objects move as a result of force such as pushing, pulling, or gravity.

  • The amount and location of the mass affects how the object in a system rolls.

  • As the amount of energy in a system changes, the outcome also changes.

  • Objects are in balance when they are part of a stable system.

  • The position, location, direction, and stability of the object will change as the result of an outside force.

Weather

  • Weather conditions affect the states in which water can be found. The weather affects our daily activities.

  • Sunlight has a significant affect on the daily temperature. Weather uses a specific terminology to identify conditions. Weather forecasters use a variety of tools to predict and measure the weather.

Technology

  • Technology makes it easier to find and communicate information.

  • Many different careers involve science or technology.

  • Data can be visually represented with labeled diagrams, charts, tables, or graphs. Data can be graphically represented through bar graphs, line graphs, pictographs, or pie charts. Graphs are pictures of numbers.

  • Visual or graphic data can be analyzed to predict further change. Models make it possible to represent events or objects that cannot be duplicated.

Essential Questions - most important “big picture” questions students should be able to answer after completing learning activities.

Scientific Process

  • What common vocabulary should be used when conducting an investigation?

  • Why are predictions an important part of the scientific process? How can we make better predictions?

  • Why should we follow a plan when conducting an investigation?

  • What tools are available to gather data when conducting an investigation?

  • How does data help us explain our investigation? What are some of the ways we can collect data?

  • How can we communicate the results of our investigation to others? How can we make sure an investigation is done the same way each time? 

Weather

  • How does weather affect states of matter: solid, liquid, or gaseous?

  • How does the sun affect weather daily?

  • What are some terms that help us describe the weather?

  • How are daily activities affected by the weather?

  • How do we measure changes in weather?

Technology

  • How can you utilize technology to gain knowledge and, communicate information?

  • What careers use science and technology?

  • How can data accuracy be determined?

  • How is data gained and how are experiments replicated accurately?

  • How can errors in data be discovered?

  • How can data be visually represented?

  • What is the best type of graph for specific data?

  • How does data help make better predictions?

  • How can models help complete a scientific investigation?

Safety

  • What are safe laboratory techniques?

  • What tools are needed to gather the data required, and how are they appropriately used?

Standards 
Highest Frequency Standards High Frequency Standards
Other Standards & E-skills

 
Standard 1:
Students understand the processes of scientific investigations and design, conduct, communicate about, and evaluate such investigation.
Standard 2:
Physical Science: Students know and understand common properties, forms, and changes in matter and energy.  Students know that matter has characteristic properties which are related to its composition and structure. Students understand that energy appears in different forms and can move (be transferred) and change (be transformed). Students understand that interactions can produce changes in a system, although the total quantities of matter and energy remain unchanged.
Standard 4:
Earth and Space Science: Students know and understand the processes and interactions of Earth's systems and the structure and dynamics of Earth and other objects in space.  Students know and understand the composition of the Earth, its history, and the natural processes that shape it. Students know and understand the general characteristics of the atmosphere and fundamental processes of weather. Students know major sources of water, its uses, importance, and cyclic patterns of movement through the environment. Students know the structure of the solar system, composition and interactions of objects in the universe and how space is explored.
Standard 5:
Students know and understand interrelationships among science, technology, and human activity and how they affect the world.
Standard 6:
Students understand that science involves a particular way of knowing and they understand common connections among scientific disciplines.
