Use geometry, a ruler, and a steady hand to create these amazing unfurling paper folds!

In this activity, learners stain fabrics--on purpose!

In this engineering design challenge, learners animate a facial expression and make a machine (zoetrope) that plays the animation back.

In this activity, learners construct a model of DNA to better understand the structure of DNA and protein synthesis.

In this activity, learners explore how pens have been engineered and re-engineered over time. Learners work as a team to develop a working pen out of everyday items.

In this design challenge, learners will engineer a structure and see if it can survive an earthquake they create.

In this activity, learners use a nail and magnet wire to build an electromagnet, which controls the movements of a paper dancer.

In this activity, learners explore trebuchet design. Teams of learners construct trebuchets from everyday materials.

In this activity, learners explore how voting systems have changed with engineering advances over time. Learners work in teams to design their own voting system using easy to find materials.

In this activity, learners explore how musical instruments are engineered.

In this activity, learners explore how engineers have improved roofing designs and materials in order to protect the contents of buildings.

In this activity, learners explore how the process of folding has impacts on engineering and is evident in nature.
