Suggested approach;
The EiE unit will cover many aspects of the magnetism section of the curriculum
The STIC ‘attraction’ activity provides another opportunity for practical experimentation and fun.
Discuss the use of both magnets and electromagnets in everyday life (e.g. fridge magnets, door locks, junkyard cranes, medical devices, credit cards, etc...)
Compare/contrast both forms of magnetism stressing that electromagnetism is convenient as it can be switched on/off
Discuss Gravity as a force of attraction between ALL objects that have mass
Explore action of gravity on objects here on Earth i.e. falling, tides, etc...
Explore the concept of pressure and relate it especially to air pressure
Inquiry opportunities: STIC: ‘Attraction’
This kit contains tools necessary for exploring magnetism such as U-magnets, bar magnets, ferromagnetic materials, compasses, and electromagnets. Use this kit to teach students about the one of the strongest fundamental forces in the universe.

Gears, cams, springs, connecting rods:
Suggested approach
Carrying out the EiE module (catching the wind) and the STIC; ‘Periscope’ projects will cover a large amount of concepts in this module (and they are great FUN!).
Take care to ensure that the types of motion - rotation and translation - are clearly identified.
Use other objects to clearly demonstrate the following components: gears, cams, springs, simple machines, connecting rods and ask students to bring in examples.
Explore the idea of a servomechanism and how it can be used in robots
Inquiry opportunities: STIC: Periscope
Other experiments/demos:
This kit contains 3 sets of wooden gears showing the different kinds of gear trains. Use this kit to show a simple sequence of mechanical parts in motion as well as transmission of mechanical energy

2. The tides
a. Describes the ebb and flow of the tides (rise and fall of sea levels)
Engineering is Elementary
N/A
Suggested approach
This is a very brief module that can largely be covered by using the digital simulations (Gizmos) and other digital resources (onboard, discovery etc.) to explore the phenomena of Tides and how they are related to the moon.
Inquiry opportunities: Students can use Google spreadsheets (or Excel) and use data found online about tides to plot graphs of tides versus time over a month and try to make inferences about the moon’s position

3. Solar system
a. Recognizes the main components of the solar system (sun, planets, natural satellites)
b. Describes the characteristics of the main components of the solar system (e.g. composition, size, orbit, temperature)
4. Seasons
c. Associates the changing of the revolution and tilt of Earth
b. Distinguishes between stars, constellations and galaxies
6. Meteorological systems and climates
b. Associates the average amount of precipitation with the climate of a region (dry, humid)
c. Associates the average temperature with the climate of a region (polar, cold, temperate, mild, hot)
7. Technologies related to the earth, the atmosphere and outer space
a. Recognizes the influence and the impact of technologies related to the Earth, the atmosphere and outer space on people’s way of life and surroundings (e.g. prospecting equipment, meteorological instruments, seismograph, telescope, satellite, space station)

Suggested approach
Reinvest & consolidate knowledge and concepts by constructing your school’s interstellar address and use this activity to define and categorise the differences between stars, planets and natural satellites (moons). (This was already done in grade 4 so this is a good opportunity to assess the efficacy of that learning!)
Once this address is established, use the ‘Scale of the Universe 2 ‘site to demonstrate the scale not only of our solar system but also of interstellar space (great opportunity to generate a sense of awe and wonder!)
Use a planetary data sheet/table in conjunction with the Celestia software, to compare the planets e.g. the temperature on different planets, the time is takes to orbit the sun (‘ORBITAL PERIOD’) and the time it takes to rotate on its axis (‘ROTATIONAL PERIOD”) the Gizmo comparing Earth to Venus is also useful for this!
Explore the cause of seasons so that students understand that it is not the distance of the earth to the sun causes the temperature variation, but the tilt of the Earth.
Explore the difference between ‘weather’ and ‘climate and how they are related.
Look at different regions of the Earth that have distinctive regional climates and use this as a good opportunity to mention climate change and it’s dangers
Finally explore the technologies that mankind has developed to monitor the planet both from space and from the ground
Inquiry opportunities: visit ANSC and DO some actual astronomical observation

2. Motion in plants
a. Distinguishes among the three types of motion in plants (geotropism, hydrotropism, phototropism)
b. Explains how the types of motion in plants enable them to meet their basic needs
Engineering is Elementary
N/A
Suggested approach
Explain that it’s not just animals that move but that plants can also move very slowly.
Explain that these movements are called TROPISMS and that these movements are always either TOWARDS or AWAY from a certain stimulus.
If a plant part moves TOWARDS something it is a POSITIVE TROPISM
if a plant part moves AWAY from something it is a NEGATIVE TROPISM
Examples of TROPISMS to discuss with your class;
GEOTROPISM – a movement towards/away from GRAVITY (the Earth)
PHOTOTROPISM – a movement towards/away from LIGHT
HYDROTROPISM – a movement towards/away from WATER
So plant shoots are positively phototropic as they grow/move towards the light and plant roots are positively geotropic and positively hydrotropic as they growth towards both the Earth and towards water.
Watch ‘Phototropism and Geotropism Time Lapse Montage’ to illustrate this
Explain how these tropism benefit the [plant
Inquiry opportunities: a GREAT activity is to grow cress seeds in 3 different conditions; 1) multidirectional light 2) dark 3) unidirectional light (see SA for details about how to do this) and use the SMARTER SCIENCE framework to scaffold the generation of hypotheses
