SC.2.N.1.3

Ask "how do you know?" in appropriate situations and attempt reasonable answers when asked the same question by others.
General Information
Subject Area: Science
Grade: 2
Body of Knowledge: Nature of Science
Idea: Level 3: Strategic Thinking & Complex Reasoning
Big Idea: The Practice of Science -

A: Scientific inquiry is a multifaceted activity; The processes of science include the formulation of scientifically investigable questions, construction of investigations into those questions, the collection of appropriate data, the evaluation of the meaning of those data, and the communication of this evaluation.

B: The processes of science frequently do not correspond to the traditional portrayal of "the scientific method."

C: Scientific argumentation is a necessary part of scientific inquiry and plays an important role in the generation and validation of scientific knowledge.

D: Scientific knowledge is based on observation and inference; it is important to recognize that these are very different things. Not only does science require creativity in its methods and processes, but also in its questions and explanations.

Assessment

Classification Performance Task:

Using simple items, colored shapes, students use a binary classification system to divide objects, then justify their scheme.

The task assesses primary students' abilities to perform process skills such as classification by using observable differences and similarities.

This task is designed to take students approximately 8 minutes to complete.

Lesson Plans

Gr. 2 Lesson 3-Wet Season-Dry Season Fish Relay:

Students will run a relay race imitating parent Wood Storks feeding their babies; one team during the wet season, the second team during the dry season. Students will draw connections from this relay to what happens to aquatic life as the waters in the Everglades dry.

Type: Lesson Plan

Crazy Crayons!:

In teams, students will make a decision on how to select the best crayons for a school supply store based on various crayon characteristics such as cost, transfer to paper, vibrancy of color, color residue, and breakage.

Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. Click here to learn more about MEAs and how they can transform your classroom.

Teaching Ideas

Here Comes The Sun:

This activity will have students predict, measure and record temperatures and provide evidence showing that the sun is the source of heat and light for Earth.

Type: Teaching Idea

Investigating Oobleck: Solid or Liquid?:

The students will make their own predictions and conclusions on whether Oobleck is a solid or liquid by using focus observations, conducting focus explorations, raising questions, clarifying questions, and making conclusions about Oobleck.

Type: Teaching Idea

Investigating The Water Cycle - Evaporation:

In this water cycle activity, students investigate the evaporation process by participating in an outdoor evaporation experiment held on the school grounds. Students will determine where evaporation takes place the fastest and how nature and humans can affect the process. Observations will be done and data is recorded in each student's science notebook so that the process can be discussed and analyzed.

Type: Teaching Idea

More About Wet Soils:

Students discover unique components of soil when dry or wet.

Type: Teaching Idea

Solid or Liquid?:

In this chemistry lesson students will investigate if certain materials are solids or liquids. Students are expected to make predictions, record observations, draw conclusions, and formulate questions for further investigation.

Type: Teaching Idea

What Makes Things Move?:

Students will use an inquiry based approach to discover how things move. They will discover that a push and a pull are forces that put things into motion. They will also investigate how friction is a force that slows a moving object.

Type: Teaching Idea

Unit/Lesson Sequences

Matter: Solids:

In this unit, properties of matter are introduced and solids are explored. Exposure to the engineering design process synthesizes information learned about solids and asks students to create a homemade play dough recipe.

Type: Unit/Lesson Sequence

Water and Wind in Weather:

This unit builds on concepts learned in the "Weather Measure" resource for Grade 2. Students are introduced to evaporation and wind. "Windmills" synthesizes information about how wind can move objects by engaging students in the engineering design process in a project that calls for the design and construction of a functioning windmill that can lift a weighted cup.
