• Get out the ruler and the plates required for the lesson (see the heading "Things you need").

• Eazymecs School Package

• Stopwatch

Students will:

• Develop knowledge about technical solutions and how parts interact to achieve function and effectiveness.

• Improve their ability to carry out technology development and design work.

• Develop their ability to conduct and follow mathematical reasoning.

1. Discussion about towers:

   • What characterizes a tower?

     • It is a tall building or building component with a relatively small base area.

     • Towers can be used for views, communication, or as part of a castle or church.

1. Divide the students:

   • Divide the students into groups of at least two participants (maximum 5 groups).

2. Build challenge:

   • Have each group choose one plate at a time until all pieces are chosen.

   • Challenge the groups to build the tallest possible tower with the chosen plates within 20 minutes.

     • The competition element can be adapted depending on the student group or removed.

3. Measurement and evaluation:

   • When time is up, identify the tallest tower and measure its height using a ruler.

   • Challenge the groups to disassemble their towers and put the pieces back in the box as quickly as possible.

• Tell us which group built the tallest tower and which group was the fastest at putting it together.

1. Geometry:

• Comparisons and estimates of quantities, measurement of length, mass, volume and time with modern and older units of measurement.

2. Problem solving :

• Strategies for solving mathematical problems in student-centered situations. Formulation of mathematical questions based on everyday situations.
