Recognize that scientists perform experiments, make observations, and gather evidence.
Number: SC.4.N.1.In.5 Category: Independent
Date Adopted or Revised: 02/08 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.

Lesson Plan

Name Description
Observing a Physical Change:

In this lesson, students are shown the difference between physical and chemical changes by dissolving and crushing seltzer tablets. Students learn to recognize that physical changes involved changes in size, shape, or texture, while chemical changes involve the formation of a new substance.

Unit/Lesson Sequences

Name Description
Chemical Change Investigations | Inquiry in Action: In this series of 10 investigations, students gain experience with the evidence of chemical change - production of a gas, change in temperature, color change, and formation of a precipitate. Students begin by observing that similar-looking powders can be differentiated by the way they react chemically with certain test liquids. Students then use their chemical tests and observations to identify an unknown powder and, in a follow-up activity, to identify the active ingredients in baking powder. Students continue to explore chemical change by using a thermometer to observe that temperature either increases or decreases during chemical reactions. Then they control these reactions by adjusting the amount of reactants. In another set of activities, students use the color changes of red cabbage indicator to classify substances as acids or bases, neutralize solutions, and compare the relative acidity of two different solutions. Students conclude the investigation by comparing a precipitate to one of the reactants that formed it. Students see that a new substance was created during the chemical reaction. Information and questions about photosynthesis and cellular respiration are included as examples of chemical changes on pages 316-318 of this resource.
Measuring Mass:

In this unit, students will first do research and study the Law of Conservation of Mass and learn how to form a hypothesis. After they learn how to form a hypothesis, they will use balance beams to measure clay and crayons.

Plants Parts and Life Cycles:

In this unit, students learn about various plants, their parts, their life cycles, and the importance of bees in plant reproduction.

Pollution:

In this lesson students will learn about pollution and its effects. They will learn in depth about pesticides and see its harmful effects that they might not have realized at first. The students will simulate a landfill and see what objects will decompose and which objects won't. They will create their own solutions to an oil spill and test to see which solution is the most effective. The students will observe the effects oil has on water birds. Through this they will determine the long term damage done by an oil spill.

Weathering and Erosion:

In this unit, students learn about weathering and erosion (and different types of weathering and erosion) through different models and activities. An engineering design competition asks students to synthesize knowledge about erosion to create an erosion-blocking process/product for the Atlantic Coast.
