Grade 4Science1 days
★★★★★
3.0 (1 rating)
This project, designed for 4th-grade science students, investigates how the speed of rolling objects relates to their energy through the use of ramps. Students design and build their own ramps, conduct experiments to measure object speed and energy, and analyze data to understand the relationship between these two factors. The project emphasizes data collection and analysis, scientific explanation skills, and critical thinking, with activities including design sketching, ramp construction, and empirical experimentation. The project culminates in students using evidence to construct explanations about the speed-energy relationship, fostering an understanding of physical principles aligned with NGSS standards.

NGSS

4-PS3-1
Primary
Use evidence to construct an explanation relating the speed of an object to the energy of that object.Reason: This standard is directly tied to the exploration of energy and speed in the context of using ramps. Students will use experimental data to construct explanations about physical principles.

Entry Events
