Our goal for this project was to create a holder that would allow the PASCO Dynamic Carts to hold more than two bar masses. This would allow students to be able to test more trials in labs and demonstrations in science classes by having more variety in the mass of the cart.

Before, the PASCO Dynamic Cart could only hold two masses securely. Even though other masses could lie on top, there was no support. When the PASCO Dynamic Cart hit the end of the track there was nothing to prevent the bar masses from falling off which could affect data, damage materials, and harm others.

The holder is also meant to be 100 grams for easy calculations.
