Grade 8, Health and Communicable Diseases Unit
Duration: @ 2 weeks

Overview
View the Video Introduction. In this unit, you will learn about making healthy choices that will help you avoid addictive substances and communicable diseases. You will use the Scientific Process to explore health related issues. You will construct your own understanding through an inquiry-based approach. Activities include open-ended investigations, small-group discussions, exploratory writing and reflective reading tasks, and long-range projects.

Enduring Understandings - important ideas that students should carry with them years beyond the instruction received this year.

  • Scientists investigate the world around them and communicate to others through the scientific process.
  • The scientific process is the basis of an integrated approach to understanding our world. (topic/problem, testable question, hypothesis, procedure)
  • Scientists use a plan to carry out an investigation (variables, control, data, observations, investigations).
  • Scientists select, appropriate tools to collect, organize, and record data using the metric system in tables, charts, and graphs. Scientists analyze data for reliability and validity to form a conclusion. Scientists analyze data to infer past and predict future events.
  • Scientists ask questions based on their investigations and these questions can lead to new investigations.
  • Scientists communicate the results of their investigations in many formats and appropriate ways.
  • The world is affected by the interrelationship of science and technology.
  • New technology continually impacts human activity.
  • Experiments must be controlled and have reproducible results.
  • Scientists identify, determine, compare, and control variables. Scientists must be objective and bias free when examining their work. Scientists communicate their results using various methods.
  • Scientists use models to predict change.
  • Safety is a primary concern with all laboratory techniques.

Essential Questions - most important “big picture” questions students should be able to answer after completing learning activities.

  • What is a testable question that leads to a proposed hypothesis? How is a testable question developed?

  • How do scientists design a plan for investigating a testable questions? How is an investigation organized?

  • How do scientists develop and perform a scientific investigation? What are the independent/manipulated and dependent/responding variables? What is the standard of control?

  • What are the appropriate tools, technologies, and measurement systems used by scientists?

  • How do scientists interpret and evaluate data? How do scientists infer/predict past and future events?

  • What new questions have arisen based on unexpected results of the investigation?

  • How is scientific information effectively communicated to specific audiences?

  • What are the advantages and disadvantages of using technology to solve problems?

  • How has technology influenced the way people work? What are advantages/disadvantages created by new technology? How do people use science and technology in their professional lives?

  • How do controlled/uncontrolled variables affect the outcomes of experiments?

  • How do you identify, compare, and control variables in an investigation?

  • How does bias, opinion, and evidence affect the way science is communicated in various media?

  • What are some different sources and methods a scientist uses to collect and record data?

  • How can models help us predict future outcomes.

  • What are safe laboratory practices?

Standards
Highest Frequency Standards  High Frequency Standards  Other Standards & E-skills

 
Standard 1: Students understand the processes of scientific investigations and design, conduct, communicate about, and evaluate such investigation.

Standard 2: Physical Science: Students know and understand common properties, forms, and changes in matter and energy. Students know that matter has characteristic properties which are related to its composition and structure. Students understand that energy appears in different forms and can move (be transferred) and change (be transformed). Students understand that interactions can produce changes in a system, although the total quantities of matter and energy remain unchanged.
Standard 5:
Students know and understand interrelationships among science, technology, and human activity and how they affect the world.
Standard 6: Students understand that science involves a particular way of knowing and they understand common connections among scientific disciplines.

Parents

When parents ask their teenagers what happened at school, they often get very vague responses. You can demonstrate your support of your child's learning by asking specific questions like, "What topic are you studying this week in science? Share the topics you are interested in and why. While driving together, there are games you can play to foster good communication.  Ask your teen to pick a science topic and quiz you by posing questions for you to answer. Don't be intimidated if your child outscores you. Teaching information to someone else is the best way to remember information.  You will be giving your teen an opportunity to demonstrate his or her understanding of science information, and boost his or her confidence in learning.
