Level 6: The AstraZeneca Human Edge
Section A
Exhibit: Hanging Skeletons
Topic: Human Health and Body Systems
A1. Exposed tooth roots indicate gum disease. Health, nutrition and dental care have changed a lot since these two men lived. Dental diseases were much more common.
Section B
Exhibit: Ins and Outs
Topic: Human Health and Body Systems
B1. Relaxed: Diaphragm is up and lungs are deflated. Contracted: Diaphragm is down and lungs are inflated.
Section C
Exhibit: Mighty Muscle
Topic: Human Health and Body Systems
C1. Answers will vary.
C2. Answers will vary. Students may or may not report arm tiredness, but they are less likely to notice their heart feeling tired (see C3).
C3. Your heart muscles are made of different types of cells than your other muscles, which keeps them from getting tired. However, this also means you can’t voluntarily control your heart muscles. If your arm muscles were made of these cells, you would not be able to control the movement of your arms!
Section D
Exhibit: Immunity Mirror
Topic: Human Health and Body Systems
D1. The virus enters the airway, infects your cells and causes damage before your immune cells contain the infection.
D2. The virus enters the airway. Your antibodies respond quickly to block the virus before it can damage your cells.
Section E
Exhibit: How Do Vaccines Keep Communities Safe?
Topic: Human Health and Body Systems
E1. Answers will vary.
E2. Answers will vary based on the responses to E1. In this activity, the student is representing a person with the disease. The dots on the floor represent other individuals in the community; they will turn red when each individual becomes infected. The percentage of vaccinated individuals impacts the spread of disease. Highly contagious viruses, such as measles, require higher levels of community immunity to prevent their spread.
E3. See E2.
Level 6: Science Arcade
Section F
Exhibit: 200 kg Pendulum
Topic: Forces Acting on Structures
F1. Answers will vary.
F2. The best way to make the pendulum move is to use a similar strategy to pushing someone on a swing, but with a pulling motion instead. Pull the pendulum only when it is closest, and then release when it begins to move away. It will take many of these small pulls to build up momentum.
Level 6: The Bruce Poon Tip Living Earth Hall
Section G
Exhibit: The TELUS Rain Forest
Topic: Properties of and Changes in Matter
G1. The condensation comes from water that has been released from leaves and has evaporated from damp surfaces. This water then condenses into a liquid on the walls.
G2. Physical Change.
Section H
Exhibit: A Shaft in the Making
Topic: Properties of and Changes in Matter
H1. The limestone is being slowly dissolved by the vinegar.
H2. Chemical Change.
Section I
Exhibit: Pedal Power
Topic: Properties of and Changes in Matter
I1. Kinetic, electric, light, sound and heat energy are all being produced.
I2. All energy on Earth comes from the Sun. You get your energy from food (either plant- or animal-based), which cannot grow without the light of the Sun. (Plants get their energy directly from the Sun, while animals get their energy from the plants.) When you pedal the bikes, this energy from your body is transformed into other types of energy.
Level 6: The Weston Family Innovation Centre
Section J
Exhibit: Windblown Walls
Topic: Forces Acting on Structures
J1: Internal forces: Tension and compression. External forces: Gravity and the weight of the structure itself.
J2. Answers will vary. Students may mention the strength of the material(s) they used, the internal forces or the shapes they used to construct their structure.
J3. Students can use strong shapes, such as triangles or arches. They can also create a wide base to support the structure.
