Engineered Music
Source Institutions
In this activity, learners explore how musical instruments are engineered.

Design a Flavor: Experiment to Make Your Own Ice Cream Flavor!
Source Institutions
In this delicious activity, learners get to make, taste-test and compare their own "brands" of homemade strawberry ice cream.

Music and Sound
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Music and Sound) is a full inquiry investigation into sound frequency.

Building with Wonderful Junk
Source Institutions
In this activity (page 4), learners work in groups to plan and build large structures using recyclable materials they have brought from home.

Ancient Sun Observations
Source Institutions
In this activity, learners make their own Sun tracker to explore how ancient civilizations around the world studied the Sun.

Design and Build a Wind Vane
Source Institutions
In this activity, learners design and build a simple wind vane —one of the oldest kinds of weather tools— and use it to show wind direction.

Clay Beams and Columns
Source Institutions
In this activity, learners make or use pre-made clay beams to scale and proportion. Specifically, they discover that when you scale up proportionally (i.e.

Size, Scale and Models
Source Institutions
In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

Building Bingo
Source Institutions
In this on site "field trip" activity (located on pages 6-9 of PDF), learners get hands-on experience identifying building materials by playing "Building Bingo".

Environmental Chemistry
Source Institutions
In this activity with several mini experiments, learners explore the chemistry that helps scientists learn about the environment and how they can help save it.

Make Your Own Mini Mini Golf Course
Source Institutions
Build your own Mini Mini Golf Course and learn about hands-on building and design, basic circuitry, motion modules and more!

Waterproof that Roof!
Source Institutions
In this activity, learners explore how engineers have improved roofing designs and materials in order to protect the contents of buildings.

Build Your Own Robot Arm
Source Institutions
In this lesson, learners develop a robot arm using common materials. Learners explore design, construction, and teamwork, as well as materials selection and use.

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

Building Tall
Source Institutions
In this engineering activity (page 2 of PDF), young learners investigate how a wide base can make a building more stable. Learners use blocks or boxes of different sizes to construct stable towers.

From the Internet to Outer Space
Source Institutions
In this activity, learners will use Google Sky to observe features of the night sky and share their observations.

As Straight as a Pole
Source Institutions
In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

Designing a Wall
Source Institutions
In this engineering activity (page 5 of PDF), young learners investigate how materials and design contribute to the strength of a structure, particularly walls.

Levers at Play
Source Institutions
In this activity, learners consider how a simple machine, a lever, turns a small push or pull (a small force) into a larger--or stronger--push or pull (a larger force).
