The Mission

25 min

Storyline

Using their knowledge of forces and motion, the crew will fend off pesky GAL-Delilahs that are disassembling train tracks in Taipan.

After RALF and his robotic friends go head-to-head with a swarm of a GAL-Delilahs, the crew will determine which of our forces are most in need of backup by analyzing balanced and unbalanced forc...

3-Dimensional Science

Phenomenon

Patterns in motion can be observed and measured to predict future motion.

Science and Engineering Practices

Analyzing and Interpreting Data

Students are engaged in examining the information related to forces and motion and applying it to make informed decisions.

Developing and Using Models

Students use a computer model to predict the train's motion based on the height of the tracks. Students use the model and corresponding data to determine where to place the HELP based on the data and the height of the tracks.

Crosscutting Concepts

Patterns

Patterns can be observed in a variety of natural and human-made systems. By identifying patterns, students can make predictions and test hypotheses about the behavior of these systems.

Cause and Effect

By intervening in this situation, students can directly observe how their actions influence the outcome of the tug-of-war.

Systems and System Models

Throughout the mission, students observe several systems in action, such as the forces exerted by the GAL-Delilahs and the drones, as well as the motion of the train influenced by the height of the tracks.
