to vehicles to turbines.
Connect with “I am unique.” How you are coming to school? How are you going to favorite
places? How the wheels are connected? Which of your toys have also wheels? What about
tricycles and bicycles?
Connect with “I am a scientist.” Explore,
examine and investigate how the wheels evolved and
how they work. Connect with “The store.” Who is
transporting products in the store and how? How this
great invention improved the way of our life?
Connect

“Design

and
