BCPS Curriculum / Maryland State Curriculum/Next Generation Science Standards
2-ESS-2.1 Compare multiple solutions designed to slow or prevent wind or water from changing the
shape of the land.
Common Core State Standards
Reading: 1. Read closely to determine what the text says explicitly and to make logical inferences from it;
cite specific textual evidence when writing or speaking to support conclusions drawn from the text.
Writing: 7. Conduct short as well as more sustained research projects based on focused questions,
demonstrating understanding of the subject under investigation.
Standards for the 21st Century Learner
1.1.6 Read, view, and listen for information presented in any format (e.g. textual, visual, media, digital) in
order to make inferences and gather meaning.
2.1.3 Use strategies to draw conclusions from information and apply knowledge to curricular areas, realworld situations, and further investigations.
ISTE NETS - National Educational Technology Standards for Students
3. Research and Information Fluency: Students apply digital tools to gather, evaluate, and use information.
b. Locate, organize, analyze, evaluate, synthesize, and ethically use information from a variety of
sources and media.
4. Critical Thinking, Problem Solving, and Decision Making: Students use critical thinking skills to plan and
conduct research, manage projects, solve problems, and make informed decisions using appropriate
digital tools and resources. c. Collect and analyze data to identify solutions and/or make informed
decisions.
