Cartesian Diver
Source Institutions
In this quick activity (page 1 of the PDF under SciGirls Activity: California Fish), learners will build a simple Cartesian Diver in an empty 2-liter bottle.

If Anyone Can, Icon
Source Institutions
In this activity, learners create their own icons for a forecast-at-a-glance poster for their classroom/learning space.
Making Rivers
Source Institutions
In this outdoor water activity, learners explore how to change the direction of water flow. Learners make puddles in dirt or use existing puddles and sticks to make water flow.

Growing Food From Scraps
Source Institutions
In this activity, learners will explore vegetative propagation while preparing food scraps to grow into plants.
Energy Audit
Source Institutions
In this lesson, learners will practice graphing and statistically analyzing data.

Speedy Shelter
Source Institutions
In this design challenge activity, learners invent an emergency shelter that can fit a person and is sturdy and quick to build.

Polar Opposites
Source Institutions
In this activity, learners make a 3-D model of magnetic fields by inserting a small, strong magnet into a sphere.

Exploring Fabrication: Self-Assembly
Source Institutions
In this activity, learners participate in several full-body interactive games to model the process of self-assembly in nature and nanotechnology.

Great Steamboat Race
Source Institutions
In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.

Saguaro Nest Cavities
Source Institutions
This activity (on page 3 of the PDF under GPS: Cactus Activity) is a full inquiry investigation into how some desert birds keep their cool.

From the Ground Up
Source Institutions
In this plant science activity, learners conduct four experiments to observe how plants respond to sunlight and gravity.

Community Wind Project
Source Institutions
In this thought-provoking activity, learners plan a hypothetical project to build and operate wind turbines in their community.

Weather Vane
Source Institutions
In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.

Moving On Up: Capillary Action 1
Source Institutions
Over the course of several days, learners explore the property of water that helps plants move water from roots to leaves or gives paper towels the capacity to soak up water.

Save Your Skin
Source Institutions
This is a fun activity about the power of the Sun and the importance of using sunscreen to protect your sensitive skin from its rays.

What-a-cycle
Source Institutions
In this activity, learners act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.

A Crayon Rock Cycle- Sedimentary
Source Institutions
This is part 1 of the three-part "Crayon Rock Cycle" activity. In this activity, learners explore how sedimentary rocks form.

Weather Stations: Winds
Source Institutions
In this activity, learners use a toaster to generate wind and compare the appliance's heat source to Jupiter's own hot interior. Learners discover that convection drives wind on Jupiter and on Earth.

Automotive Emissions and the Greenhouse Effect
Source Institutions
In this activity about global climate change, learners will conduct an experiment and collect data to compare the amount of carbon dioxide (CO2) in four different sources of gases.

Build a Giant Puzzle!
Source Institutions
In this activity, learners assemble large cubes to make nano-related images. Learners discover how different objects are related to nanoscience and nanotechnology.
