What what we did in our last STEM lesson.
In our last STEM lesson my group and I finished our end product. We were not able to use our Initial idea (the train track) but we had some last minute modifications. We had to make a drag strip still using the pivoting middle train track but instead of it being fixed to the track the user can freely move it only limited to the half way mark. Next lesson my group and I are going to be showing off what we have made to teachers, students and visitors.
