HOW WILL IT BE TAUGHT?
Engineering is Elementary;
Suggested approach;
Class discussion on how things can move, and that it is FORCES which cause things to move
categorise forces as PUSH, PULL TWIST also examples and DEMO with soccer ball (throwing squeezing and stretching),
effects of a force on an object (i.e.. sets it in motion, changes its motion, stops its movement, changes objects ‘shape or size)
Use EiE module to look at forces & structures in terms of bridges
Carry out Paper Sandals and Pennies on a Bridge investigations
Explore electrostatic attraction through experimentation - moving tap water, balloon and paper, etc… and to understand attraction & repulsion
Inquiry opportunities:
S.T.I.C; ‘Making paper sandals’ (highly recommended)

HOW WILL IT BE TAUGHT?
Suggested approach
Brainstorm what is meant by ‘machine’ to evolve definition then use class discussion to develop the idea of machines being useful as they reduce the effort required to perform a task.
Introduce main types of simple machines lever, inclined plane, screw, pulley, winch, wheel (with practical demo of each if possible)
Great video on pulleys https://www.youtube.com/watch?v=M2w3NZzPwOM
Demonstrate ROTATION & TRANSLATION as motion types and relate to machines/mechanisms
Identify mechanical parts in mechanism (e.g. gears, cams, springs, connecting rods) in familiar object
Use the EiE unit ‘Marvelous Machines’ and STIC demos (see below) to reinforce concepts.
NOTE – this area of the curriculum is usually weak at the high school level so it’s important to establish a firm grasp of these concepts at the elementary level
Inquiry opportunities: STIC My Animated Object, STIC Mechanical Bugs (both V. GOOD!)

Notes
HOW WILL IT BE TAUGHT?
Suggested approach
Brainstorm what the students know about how the Earth moves
Review the ideas that the Earth rotates ‘orbits’ the sun and that this takes 365 days and that the Earth rotates on it’s axis and that this takes 24 hours
Investigate why some days and nights are longer or shorter than in other places around the world.
Compare days (rotational period) of other planets
Complete EiE module
Inquiry opportunities:
Other experiments/demos:
DEMO; Use flashlight and globe in darkened room
Mark your school’s location on Google Earth and show it spinning into day and night
Students create a sundial to observe the earth’s rotation for a school day

Stellarium (HIGHLY RECOMMENDED) – this is a program you can download and, with a projector, you can turn your classroom into a planetarium
‘Special Space Unit’ from Science.gc.ca is also valuable
HOW WILL IT BE TAUGHT?
Engineering is Elementary
N/A
Suggested approach
Assess pre-existing knowledge by trying to construct your school’s interstellar address
Use this activity to define and categorize the differences between stars, planets and natural satellites (moons).
Use Celestia software to explore notions about the solar system and the orbits of both the Earth and Moon.
Explore the reasons for the lunar cycle and both lunar 7 solar eclipses
Explore the idea of phases of the moon with a daytime moon and ping pong ball
Use Stellarium to turn your class into a virtual planetarium and introduce the idea of constellations
Explore the idea of ‘sensing’ the Earth space photographer (remote sensing) and by equipment on the ground such as seismometers.

on the move
Essential Question:
how do animals move?
WHAT DOES THE STUDENT NEED TO KNOW?(POL)
ed-tech resources:
Gizmos -
Arundel Nature and Science Centre (ANSC):1.a, b Animal Tracking Spring and Fall -or- Animal Tracking Winter - Field Trip to ANSC for field experience in discovering animal tracks up close. Make your own tracks!1. a, b Mysteries of the Water World: Pond and Stream Studies discover how different animals move in various environments.1. a,b How Many Legs? - Entomology - discover how different animals move in various environments due to their adaptations.
sam's lessons:
Animals on the move guided inquiry and collaborative lesson:
students use the essential question to anchor the lesson
predictions about the essential question can be made
students work in teams of 4 to sketch and explain (on a large poster paper) how and why the animals are moving the way they do
students use the experiences they've had to make a claim about the essential question - making an justifying scientific claims (AST format)
students try to reason with evidence ("what do I know that makes me think this...")
HOW WILL IT BE TAUGHT?
Suggested approach
Consolidate the idea that there are some characteristics common to ALL living things and that one of these is LOCOMOTION – ‘moving’
Brainstorm the many types of ways in which animals can move and try to make lists/categories of examples of each. The video segment ‘Animal Motion’ could be helpful here.
Direct observation of animals in class (e.g caterpillar, ant etc) will help develop observational skills
The EiE knee brace module is a great way to wrap the module

Suggested approach
Explore concepts of ‘species’ ‘population’ and ‘habitat’ and demonstrate this by reference to different examples e.g. population of camels in Sahara or population of arctic foxes in Canada
use examples to demonstrate what the habitat is providing for the animal
use examples to demonstrate the idea of ADAPTATION
GET OUTSIDE and study the habitat of the school yard and the adaptation and populations of the animals that live there
Discuss the impact of us humans on the environment and look at ways that we can reduce this impact e.g. recycling
