This is a quick activity (on page 2 of the PDF under Butterfly Wings Activity) that illustrates how nanoscale structures, so small they're practically invisible, can produce visible/colorful effects.

In this drawing/mapping activity, learners design plots of land while incorporating positive strategies for improving water quality.

In this activity, learners create a colorful bookmark using a super thin layer of nail polish on water. Learners discover that a thin film creates iridescent, rainbow colors.

Make a kite out of a garbage bag, shower curtain, painting tarp--anything light, thin, flexible and plastic!

In this engineering activity, learners explore simple machines and then build cardboard automata using cams.

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

This activity was designed for blind learners, but all types of learners can explore the process used to cast and mold molten metal, glass, and plastics.

In this activity (on page 2 of PDF), learners make their own totem poles out of recycled materials.

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 activity, you take regular dominoes, and turn them into conductive switches that can turn on a LEGO RCX block or Pico Cricket (micro controller). LEGO RCX block or Pico Cricket is required.

This fun and simple hands-on astronomy activity lets learners explore model planets (that they or an educator will create), using methods NASA scientists use to explore our Solar System.

In this activity, learners will engineer a new shape and use it to create a new pattern with no wasted space.

In this activity, learners design and build a NASA rover using raw pasta and candy with a limited imaginary budget.

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

In this activity, learners build small animated toys that move.

In this activity, learners build a figure that moves and "comes to life" when they pull its string.

In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

Margaret Pezalla-Granlund, a Minnesota artist, came up with this really fun and surprising activity using graphite from a pencil, connected with a Pico Cricket to tell a story: "The first time I saw s

This activity was designed for blind learners, but all types of learners can explore the process of extrusion used to produce pipes and wires in industry.

In this activity, learners will build the highest tower they can out of recycled materials.
