Body Systems and Negative Feedback: a full term of science

Ten ready-to-teach lessons for Year 9 Biological sciences. Print this pack and the term is prepared: every lesson has a plan, talk prompts, a student worksheet, cards or tickets, and answers.

AC9S9U01
compare the role of body systems in regulating and coordinating the body’s response to a stimulus, and describe the operation of a negative feedback mechanism

Start here: five minutes to Monday

  1. Skim the term at a glance on the next page.
  2. Print the lesson you need (plan, worksheet, cards).
  3. Gather everyday items under You need on the plan.
  4. Open the free interactive unit on your board.
  5. Teach from the plan: timings, prompts and answers are on one page.

No science background needed

Written for the busy generalist teacher. Plain words, common muddles, and model answers are on every plan. Safety: no open flames or boiling water unless an adult controls a warm-water step named on the plan.

On the board
This pack is the printable half of a free interactive unit. On-screen pictures include: “From stimulus to response”, “Two systems coordinate a response”, “Negative feedback: body temperature”, “The same rule: blood glucose”, “Why negative feedback keeps things stable”. Lesson plans name which picture to show.

The term teaches AC9S9U01. Lessons also work these Inquiry and Human Endeavour descriptors:

AC9S9I01develop investigable questions, reasoned predictions and hypotheses to test relationships and develop explanatory models
AC9S9I02plan and conduct valid, reproducible investigations to answer questions and test hypotheses, including identifying and controlling for possible sources of error and, as appropriate, developing and following risk assessments, considering ethical issues, and addressing key considerations regarding heritage sites and artefacts on Country/Place
AC9S9I03select and use equipment to generate and record data with precision to obtain useful sample sizes and replicable data, using digital tools as appropriate
AC9S9I04select and construct appropriate representations, including tables, graphs, descriptive statistics, models and mathematical relationships, to organise and process data and information
AC9S9I05analyse and connect a variety of data and information to identify and explain patterns, trends, relationships and anomalies
AC9S9I06assess the validity and reproducibility of methods and evaluate the validity of conclusions and claims, including by identifying assumptions, conflicting evidence and areas of uncertainty
AC9S9I07construct arguments based on analysis of a variety of evidence to support conclusions or evaluate claims, and consider any ethical issues and cultural protocols associated with accessing, using or citing secondary data or information
AC9S9I08write and create texts to communicate ideas, findings and arguments effectively for identified purposes and audiences, including selection of appropriate content, language and text features, using digital tools as appropriate
AC9S9H01explain how scientific knowledge is validated and refined, including the role of publication and peer review
AC9S9H02investigate how advances in technologies enable advances in science, and how science has contributed to developments in technologies and engineering
AC9S9H03analyse the key factors that contribute to science knowledge and practices being adopted more broadly by society
AC9S9H04examine how the values and needs of society influence the focus of scientific research
