Jill ⭐️ ⭐️ ⭐️ ⭐️ ⭐️Extremely Satisfied

Wow! This was a great resource! My students learned a lot and it connected really well to our energy unit. Great design thinking.

Ella ⭐️ ⭐️ ⭐️ ⭐️ ⭐️Extremely Satisfied

Using for my STEM camp. My students love this!!! Love how well connected the science is and students need to think about criteria and constraints and the design process. Incredibly engaging. Kids are thrilled with their cars.

Standards Addressed:

NGSS 3-5-ETS1-1. Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.

NGSS 3-5-ETS1-3. Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.

NGSS MS-ETS1-2.Evaluate competing design solutions

using a systematic process to determine how well they meet the criteria and constraints of the problem.


Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.


Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.
