Puppet Power
Source Institutions
In this mechanical engineering activity, learners design shadow puppets with moving parts and use them to tell stories.
Genetics the Easy Way
Source Institutions
In this activity, learners make critters out of recyclables and apply the rules of mathematics to solve genetics problems.
Sustainable Grazing
Source Institutions
In this activity, learners investigate the food, water, and space needs of common livestock animals.
Grab and Go
Source Institutions
In this engineering activity, learners design and build a mechanical arm to lift a small item.
Soccer Kicks
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Soccer Ball Kick) is a full inquiry investigation into transfer of motion.
Prepare for a Construction Zone Field Trip
Source Institutions
In this activity, learners explore work, forces, simple machines, and construction. This lesson guide includes simple ways to demonstrate these principles as well as hands-on activities.
Infrared Investigations
Source Institutions
In this activity, learners explore how infrared technology is used by engineers to create equipment and systems for a variety of industries.
Rubberband Rockets
Source Institutions
This fun and simple activity is a rubberband rocket design challenge! Learners will explore how tail fins can help to stabilize a flying object, while also exploring potential and kinetic energy.
Scytale Messages
Source Institutions
In this activity, learners use a soda can to decode a secret message. Learners wrap scytale (pronounced ski-tally) code around a can and challenge friends to see if they can crack the codes.
Conveyor Engineering
Source Institutions
In this activity, learners explore the engineering behind the conveyor belt and consider the impact this invention has had on transportation and the coordinated shipping and delivery of goods.
Pop Fly
Source Institutions
In this design challenge activity, learners invent a way to send a Ping-Pong ball flying high enough to catch it - like football with a twist!
Kicking Machine
Source Institutions
In this design challenge activity, learners build a machine that kicks a Ping-Pong ball into a cup lying on its side 12 inches away.
Sand Paper Rankings
Source Institutions
In this activity (2nd activity on the page), learners explore the sensitivity of their sense of touch.
Jitterbugs
Source Institutions
In this activity, learners construct bug models that "jitter" all over the table with just a battery, motor, and counterweight.
Newspaper Bridges
Source Institutions
In this activity, learners build bridges out of newspaper and tape to explore how structures are designed to bear loads.
Skewers and Garden Poles
Source Institutions
In this activity, learners build scaled-down structures and cantilevers in a series of "building out" challenges with bamboo skewers and tape.
Sock It To Me!
Source Institutions
In this activity (7th activity on the page), learners use their sense of touch to identify mystery objects hidden in socks.
Keep it Cool
Source Institutions
In this activity, learners explore how engineers have met the challenge of keeping foods, liquids, and other items cool.
Mystery of the Disappearing Cottonwoods
Source Institutions
Learners will explore the scientific mystery behind a disappearing group of trees by examining data and attempting to explain the decline.
String Shapes
Source Institutions
In this activity, learners work together to make polygons (many-sided shapes) with string. Learners sit on the floor and hold onto a piece of string slid between their thumbs and index fingers.
