How can I design affordable, hands-on physics units to engage hesitant students?

I'm a high school physics teacher trying to revamp our introductory curriculum to better engage students who are intimidated by STEM education, and I want to move beyond rote formula memorization to genuine inquiry. My biggest challenge is designing hands-on projects that are both accessible with our limited lab budget and clearly connected to core concepts like Newton's laws or energy conservation. For educators who have successfully implemented project-based learning in their science or math classes, what specific units or activities sparked the most student interest and understanding? How do you balance the open-ended nature of inquiry with the need to cover required standards, and what low-cost materials or digital simulations have you found most effective for demonstrating abstract principles in a tangible way?

Solid goal. A phenomenon-driven unit like 'What makes a toy car accelerate?' works great. Give a driving question, build ramps from cardboard, use toy cars or marbles, a meter stick, and a stopwatch. Students predict, measure, and graph speed vs time, then connect to Newton's laws. Keep the setup simple and scale the assessment to their explanations, not decoration.

To balance inquiry with standards, structure helps: (1) present a real phenomenon (gravity on a ramp), (2) have students propose a quick plan, (3) run controlled mini-experiments, (4) have them argue from data, (5) reflect and generalize. Map activities to NGSS or your state standards—e.g., forces, energy, method of scientific inquiry. Create a 4-week outline with built-in checkpoints and a simple rubric that ties predictions, data quality, and argument coherence to the standards.

Low-cost material kit: ramps (cardboard, foam-core, or PVC), cars or marbles, stopwatches, meter sticks, masking tape; optional: a cheap digital scale, a small notebook or data sheets for data collection. For data display, students can draw graphs by hand or use free tools like Google Sheets. For simulations, PhET's Energy Skate Park and Collision Lab are free and student-friendly.

PhET simulations are gold here. Energy Skate Park helps illustrate energy conservation; Collision Lab can model momentum; there are other physics sims that pair well with hands-on activities. Use them to supplement hands-on with guided questions, require students to extract data and compare to predictions.

Make it accessible: provide multiple entry points (hands-on, reading support, and short summaries), structure roles in groups, and use quick exit tickets to gauge understanding. Tie activities to standards from day one and build in checks for equity and accessibility, so no one is left behind.

Would you share your class size, grade level, and how much class time you can devote to this? If you want, I can sketch a concrete 4-week unit plan with activities, a shopping list, and a simple rubric.
