that’s a very fun space! I imagine that building ramps yourself is an important aspect of this lesson. One way to make this easier to access for your students is to create pre-assembled ramp parts.
I’ve updated the example shared above with two new Scenes (scene 2,3). Curved ramp parts can be created by attaching many smaller building blocks together, after which you group them into one single item. This allows students to simply copy the template parts and assemble their own track like this:

Building block groups like that are a good workaround to get your track building started. We’re working on improving physics collisions with more building blocks, so that smooth turns and loops will also be possible
