Year plan

Our science studies are made up of Highline Science Kits, District-approved curriculum and Kate Poaster’s Science-To-Go, our District’s science liaison. Kate Poaster supplements and enriches our kit investigations by bringing in live samples of plankton, real organs to examine, providing fun games to play and labs for us to explore.

Oceanography

We begin our year off with this unit. We explore the parts of a wave and its movement and measurement, how surface and density currents are formed, how the tides move and we make our own tidal dials to determine when high/low tides are on any given day. We explore the depth profile of the ocean floor by plotting a small section of the Atlantic Ocean and labeling its parts: continental shelf, continental slope, abyssal plain, trench, seamount, island, and midocean ridge. We end our study by examining creatures that live in our inter-tidal and neritic ocean zones, how warm blooded mammals can survive in cold ocean temperatures and the unique organ fish have that controls their buoyancy. The water cycle is also reviewed in this unit.

Simple Machines and Energy

In this unit, students learn what simple machines are, how they make work easier, and when put together how they can form compound machines. We end our study with students designing their own compound machine to do a specific task (such as ‘doing my homework’), explain what type of energy is needed to run the machine, building a 3-D model of it, and presenting their machine to the class. Students study the following simple machines and concepts:

  • Friction
  • Potential and Kinetic energy
  • Force and Work (newtons and joules)                                                                                    
  • Calculating Work (Work=Force X Distance)                                                        
  • Metric vs US Standard measurement
  • Inclined plane
  • Levers
  • Pulleys
  • Wheel and axle
  • Wedge
  • Screw
  • Where does energy come from?
  • Various forms of energy: thermal, electrical, solar, mechanical, etc.
  • Energy ‘chains’

Human Body Systems/ Family Life and Sexual Health (FLASH) and HIV/AIDS

In this unit, students use a simulation called, “Code Blue” to learn about the following systems: Respiratory, Circulatory, Digestive, Skeletal/Muscular, Nervous, and Urinary. In the simulation, students are separated into ‘medical specialty schools’ where they must learn everything about their particular body system. They take a ‘final exam’ test and, upon passing, are hired by a ‘hospital’. One student from each school is hired into a hospital to be the expert on that particular system. Once a hospital is formed, they are given a ‘patient’ who they must decide on how to make healthy. This unit culminates in a Grand Rounds Conference where each hospital explains their patient and solution to the other ‘doctors’.

The reproductive system is taught through the FLASH curriculum. By law, all students must receive Sexual Health and HIV/AIDS learning every year from 5th grade to 12th grade,
unless a parent attends a District viewing of the curriculum and signs a waiver. In 5th grade, this unit covers the male and female reproductive organs, puberty for both boys and girls, and HIV/AIDS. Also included in this unit are lessons on emotional health, friendships and family, abuse and exploitation, and hygiene.
