Physics cart with 1.5m retractable tape and three sets of wheels
Introducing our innovative cart with a retractable tape measure.
Perfect for a wide range of experiments from Year 3 up to Year 12 Physics.
Comes with a free download of 6 Experiments you can do with this cart.
The 1.5 metre tape measure is incredibly versatile and can be used to accelerate the cart with its pulling force.
Plus, our cart is designed to hold a 250ml Spring Water sipper bottle (available from Woolworths stores), allowing for a variety of experiments by adjusting the amount of water in the bottle (1ml of water equals 1 gram of mass).
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. A digital download with 5 experiments which can be carried out with the equipment.
Please note that the product does not include the 250ml sipper bottles, which can be purchased from Woolworths (12 for $6.50).
The editable 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)
Schools could use some of these experiments as assessment tasks. eg complete experiment 1 and 2 under instruction and use experiment 3 as the assessment task. Brilliant!
1. Experiment 1 - Mass and Average Speed
2. Experiment 2 - Height of Ramp and Average Speed
3. Experiment 3 - Weight of Cart and Average Speed
4. Experiment 4 - Size of Wheels and Roll Distance
5. Experiment 5 - Different Surfaces and Roll Distance
6. STEM Challenge - Can you make a sail cart?
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.
This is a nifty and cleverly designed product, which works!
We bought the physics cart for our Year 10 child to complement his learning of Newton's laws of motion at school. He has so far completed 4 of the 6 experiments and charted the results.
At face value this would be particularly useful for junior high school students (Years 7 & 8) to introduce basic concepts. However, our son created additional charts of his results (F=ma, m-g-sin-theta), proving to himself that Newton's laws actually work in practice.
By plotting lines of best fit through the data and calculating their formula, these experiments were directly relevant to his Year 10 math studies too.
Good practical stuff. Our family highly recommends.
