Physics cart - Dynamics Trolley - with 1.5m retractable tape and three sets of wheels
Introducing our innovative Physics Cart Set including a retracting tape measure (which both accelerates the cart and measures the distance)
Designed by Physics Teacher Jacob Strickling.
Perfect for a wide range of experiments from Year 5 up to Year 12 Physics.
Comes with a free downloadable 15 Lesson Workbook. It includes lessons and experiments on Energy, Forces and Newton's Laws. The experiments are all heavily based around this set.
This is a truly innovative product on quite a number of levels.
i) The 1.5 metre tape measure is incredibly versatile as it acts as both a measuring tape AND can be used to accelerate the cart with its internal spring pulling force.
ii) Student's can explore Newton's First and Second with this cart. The two experiments on F=ma are superior to those currently carried out in schools with dynamics trolleys and masses costing in the hundreds of $$$$ (TSL equipment is much safer as well and with its low cost it means student's can work in pairs)
iii) The 250ml bottle can be used to adjust the mass with water, meaning no metal weights are required.
Innovated by Jacob Strickling, this idea was birthed when he was faced with the challenge of delivering a Physics class on Newton's Second Law in Western Australia and could not bring all the required weights due to baggage limitations. Instead, he created some lightweight carts and used plastic bottles with water as a substitute for the weights.
This product consists of
1. Timber cart (made from recycled cedar blinds) 12cm long and 6cm wide
2. 1.5 metre retractable tape measure
3. Threes sets of foam wheels 3cm, 3.5cm and 4cm in diameter
4. Two wooden dowels for axles
5. Four wooden washes to ensure a frictionless roll
6. Two elastic bands to hold the bottle in place.
7. A 250ml bottle with 50ml markings
8. Two 5ml plastic syringes with silicone tubing (comes separate to plastic case)
9. A foam insert and handy plastic storage case 17cm by 11.5 cm by 3cm
10. A digital download with 15 lessons which can be carried out with the equipment.
The digital download includes the following experiments which are perfect for exploring the Scientific Method and many Science skills. (Ramps are often just tables with one end held up above the ground)
Lesson 1 – Energy and Transformations
Lesson 2 – Forces - Pushes and Pulls
Lesson 3 - Forces with Syringes
Lesson 4 – Friction Game
Lesson 5 – Surfaces and Cart Roll Distance
Lesson 6 – Balanced Forces
Lesson 7 – Mass and Inertia
Lesson 8 – Height of Ramp and Average Speed
Lesson 9 – Weight of cart and Average Speed
Lesson 10 – Size of Wheels and Roll Distance
Lesson 11 - Different Surfaces and Roll Distance
Lesson 12 – Newton’s First Law
Lesson 13 - Mass and Acceleration – Newton’s Second Law
Lesson 14 - Force and Acceleration – Newton’s Second Law
Lesson 15 – STEM Competition – Sail Away!
Schools could use some of these experiments as assessment tasks. eg complete experiment two of the experiments under instruction and then use another experiment as the assessment task. Brilliant!
Other experiments which could be investigated using this equipment include:
How does the angle affect the force down the ramp?
Does the retractable tape measure obey Hooke's Law?
Is the force exerted by the tape measure constant?
Overall, our cart with retractable tape measure is a must-have for anyone looking to conduct engaging and informative Physics experiments.
