STEP 1: •Students watch the video about the problem in the next link:

RETO STEAM:creación del puente

STEP 2: •Students design and build their bridge prototype and test their resistance with different weights. •Students will only be able to use a kilo of spaghetti, adhesive tape and hot silicone.

•The maximum dimensions of the bridge will be as follows: * LENGHT: 78 CENTIMETERS * Height: 39 centimeters

•Students think about the problem. An asteroid has fallen and separated the city in two. We have to build a bridge, but… How do we do it? •If you want, you can use the graphical organizer about how to solve problems (Thinking-Based Learning) •Students in groups think in different solution and they choose the most appropriate option. To do this, they investigate and observe different bridges. How can they bear more weight?

STEP 3: * Competition between countries: •We make a meeting virtual in which students from each country will show to other partner how much weight their bridge prototype can support.&nbsp;Each country will only participate with a bridge. • The country that can support the most weight without collapsing will win.
