With bike-pump rockets, imploding cans and a marshmallow bazooka, this show about pressure will blow your mind!
Age: Primary: Yrs 3-5
Program Length: 30-45 minutes
Audience: Up to 2 classes per show (approx 60 students)
- Explore different causes of pressure
- Discover the differences between positive and negative pressure
- See how chemical reactions can make gases under pressure
- See how temperature changes pressure
- Develop their scientific skills of Enquiry, Prediction, Observation, Explanation.
- 1x power outlets
- Access to a water tap and sink
- Space requirements: 3m x 3m.
Formal curriculum substrands
- Chemical, physical, and earth science
Links with Overarching Ideas
- Matter and energy – energy and temperature can cause changes in pressure
- Stability and change – chemical reactions producing new substances, changes in temperature cause changes in pressure.
- Scale and measurement - Measurement of positive and negative pressure.
- Patterns order and organisation – different methods of changing pressure
- Forces can be exerted by one object on another through direct contact or from a distance (ACSSU076)
- Solids, liquids and gases have different observable properties and behave in different ways (ACSSU077)
- A change of state between solid and liquid can be caused by adding or removing heat (ACSSU046)
- A push or a pull affects how an object moves or changes shape (ACSSU033)
- Different materials can be combined, including by mixing, for a particular purpose (ACSSU031)
- Science involves asking questions about, and describing changes in, objects and events (ACSHE034)
- Heat can be produced in many ways and can move from one object to another (ACSSU049)
- Changes to materials can be reversible, such as melting, freezing, evaporating; or irreversible, such as burning and rusting (ACSSU095)
- Objects are made of materials that have observable properties (ACSSU003)
- Everyday materials can be physically changed in a variety of ways (ACSSU018)
- Science involves making predictions and describing patterns and relationships (ACSHE061).
NSW Curriculum Outcomes: ST2-1VA, ST3-1VA, ST2-4WS, ST2-5WT, ST2-6PW, ST2-7PW, ST2-12MW, ST2-13MW, ST3-12MW, ST3-13MW.
There are heaps of exciting things students and teachers can do with pressure following this show! Here are some suggestions:
In class and at home
- Make a Cartesian diver with a straw and some blue-tack
- Use frozen CO2 (dry ice) to explore the effects of cold temperatures and decreased pressures
- Make your own bicarb-vinegar film canister rockets
- Make your own bike-pump rocket
- Advanced: Explore what variables make the rocket go highest.
