Life science – structure & processes – grade 4 – 2

[Clarification Statement: Thorns, branches, roots, colored petals, heart, stomach, lung, brain, and skin are examples of structures.] [Assessment Boundary: Macroscopic structures within plant and animal systems are only assessed.]
[Clarification Statement: The focus is on information-transfer systems.] [Assessment Boundary: The mechanisms by which the brain stores and recalls information, as well as the mechanisms by which sensory receptors act, are not included in the assessment.]
Engaging in Evidence-Based Argumentation
In 3–5, engaging in proof-based reasoning builds on K–2 experiences and progresses to critiquing peer-proposed scientific theories or solutions by referencing applicable evidence from the natural and constructed universe (s).

What a student should be able to do to demonstrate mastery of a concept is called a Performance Expectation (PE). A Clarification Statement and/or an Assessment Boundary are included in some PEs. These can be found by pressing the “More Details” button on the PE. When you hover your mouse over a PE, it will highlight the pieces from the Science and Engineering Practices, Disciplinary Core Ideas, and Crosscutting Concepts that correspond to it.
You may learn more about a particular Science and Engineering Practice, Disciplinary Core Idea, or Crosscutting Concept by clicking on it. You will find the corresponding elements in the PEs by hovering over them.

4th grade Change is the theme of the summer! Create and maintain a science journal or science folder for each child to keep track of their notes, findings, and reflections over the summer! Week 1: June 30th to July 3rd Growth and Development ELA is a subject that a lot of people are interested in. Priority Criteria: R.1: Read carefully to decide what the text states clearly and to draw logical inferences from it; cite relevant textual facts to support conclusions taken from the text while writing or speaking. W.9 – To promote interpretation, reflection, and study, use evidence from literary or informational texts. SL.1: Prepare for and engage actively in a variety of discussions and partnerships with a variety of partners, building on others’ ideas while simply and persuasively communicating their own. 4.MD.1: Recognize relative sizes of measurement units within a single set of units, such as km, m, and cm. 4-LS1-2: Explain how animals receive various types of information through their senses, process the information in their brains, and react to the information in different ways using a model.
