(3) Encourage students to modify the model. If a student finishes the adjustment, he or she can do the “Hands-on Experiment” first.
Building blocks
(4) Hands-on Experiment Try and reduce the degree of spin on the seagull. (example: adjust the length) A Reduce electric power, or adjust the length of the 15
rope. (5) Hold a contest. Students can discuss and practice during the contest. (6) Hands-on Creativity Change the design of the model into different animals (example: eagle). Encourage students to modify their models and create their own styles, such as the eagle style.

Integrated Learning
Model
(1) Display all the models of each group. Give the winner 10 group a big hand.
Boxes
(2) A teacher can make a review of the concepts of “Spinning seagull. The reactionary force of air." Or this teacher can encourage students to share the experience about either the assembly of the model or the reflection of a game. (3) Students’ works can be displayed in the classroom.
(4) Remind students to clean up the desk, disassemble the model and put the building blocks back to the boxes.

Extension Task
(1) Hold the contest again and ask students to make a set of tracks (device) of GreenMech. After the seagull rotates, it can touch and hit a part of the tracks and trigger the device to operate. A Make a simple track to let the marbles slide down to the designated area. Students have to estimate the distance of the seagull rotation and let the seagull hit the GreenMech device so as to make the marbles slide down successfully. Record & Feedback
