General Course Information and Notes

General Notes

Laboratory investigations that include the use of scientific inquiry, research, measurement, problem solving, laboratory apparatus and technologies, experimental procedures, and safety procedures are an integral part of this course. The National Science Teachers Association (NSTA) recommends that at the high school level, all students should be in the science lab or field, collecting data every week. School laboratory investigations (labs) are defined by the National Research Council (NRC) as an experience in the laboratory, classroom, or the field that provides students with opportunities to interact directly with natural phenomena or with data collected by others using tools, materials, data collection techniques, and models (NRC, 2006, p. 3). Laboratory investigations in the high school classroom should help all students develop a growing understanding of the complexity and ambiguity of empirical work, as well as the skills to calibrate and troubleshoot equipment used to make observations. Learners should understand measurement error; and have the skills to aggregate, interpret, and present the resulting data (National Research Council, 2006, p.77; NSTA, 2007).

Special Notes:

Instructional Practices:
Teaching from a range of complex text is optimized when teachers in all subject areas implement the following strategies on a routine basis:

  1. Ensuring wide reading from complex text that varies in length.
  2. Making close reading and rereading of texts central to lessons.
  3. Emphasizing text-specific complex questions, and cognitively complex tasks, reinforce focus on the text and cultivate independence.
  4. Emphasizing students supporting answers based upon evidence from the text.
  5. Providing extensive research and writing opportunities (claims and evidence).


Science and Engineering Practices
(NRC Framework for K-12 Science Education, 2010)

  • Asking questions (for science) and defining problems (for engineering).
  • Developing and using models.
  • Planning and carrying out investigations.
  • Analyzing and interpreting data.
  • Using mathematics, information and computer technology, and computational thinking.
  • Constructing explanations (for science) and designing solutions (for engineering).
  • Engaging in argument from evidence.
  • Obtaining, evaluating, and communicating information.

Florida’s Benchmarks for Excellent Student Thinking (B.E.S.T.) Standards
This course includes Florida’s B.E.S.T. ELA Expectations (EE) and Mathematical Thinking and Reasoning Standards (MTRs) for students. Florida educators should intentionally embed these standards within the content and their instruction as applicable. For guidance on the implementation of the EEs and MTRs, please visit https://www.cpalms.org/Standards/BEST_Standards.aspx and select the appropriate B.E.S.T. Standards package.

English Language Development ELD Standards Special Notes Section:
Teachers are required to provide listening, speaking, reading and writing instruction that allows English language learners (ELL) to communicate information, ideas and concepts for academic success in the content area of Science. For the given level of English language proficiency and with visual, graphic, or interactive support, students will interact with grade level words, expressions, sentences and discourse to process or produce language necessary for academic success The ELD standard should specify a relevant content area concept or topic of study chosen by curriculum developers and teachers which maximizes an ELL's need for communication and social skills. To access an ELL supporting document which delineates performance definitions and descriptors, please click on the following link: https://cpalmsmediaprod.blob.core.windows.net/uploads/docs/standards/eld/sc.pdf

Educational Game

Stop Disasters Before They Happen:

Students attempt to save towns from damage prior to the arrival of several different natural disasters. Students will learn the importance of early prevention and actions to protect others, themselves and their property when faced with a natural disaster. Certain disasters are more appropriate for particular grade levels. Each scenario takes between 20 and 45 minutes to play, depending on the disaster for which your students are trying to prepare. There are five scenarios available, hurricane, tsunami, flood, earthquake, and wildfire. Each scenario can be played on easy, medium or hard difficulty levels. As with life, there are no "perfect solutions" to each scenario and no "perfect score", so students can play multiple times and the scenarios will still be slightly different.These simulation are part of a larger website that provides multiple links for natural disasters.

CO2: Find Out What It Means to You:

This BLOSSOMS lesson discusses Carbon Dioxide, and its impact on climate change. The main learning objective is for students to become more familiar with human production of Carbon Dioxide gas, as well as to gain an awareness of the potential for this gas to effect the temperature of Earth’s atmosphere. This lesson should take about an hour to complete. In order to complete the lesson, the teacher will need: printed copies of signs representing the different products and processes that take place in the carbon cycle (included), samples of matter that represent those products, handouts for the students to create a graphic of the carbon cycle (included) and graph paper or graphing software for students to create graphs. In the breaks of this BLOSSOMS lesson, students will be creating models of the carbon cycle as well as observing experiments and analyzing data from them. It is hoped that this lesson will familiarize students with ways in which carbon moves through our environment and provide them with some personal connection to the impact that an increased concentration of CO2 can have on air temperature. The goal is to spark their interest and hopefully to encourage them to ask and investigate more questions about the climate.
