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.

Scientific Measurement Exercise
Source Institutions
Learners measure irregularly shaped bones using a variety of measurement methods and tools. Then, they measure again using standard conventions and metric tape measures.
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.

Moon Watch Flip Book!
Source Institutions
In this activity, learners observe the moon each night for a month and draw their observations in a Moon Watch Log.

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.

Dinosaur Flesh and Bones
Source Institutions
In this activity, learners explore dinosaur skeletons.

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.

Measure the Sun's Size
Source Institutions
In this activity, learners make their own pinhole viewer in order to measure the size of the sun.

Compare Dinosaur Body Parts
Source Institutions
In this activity, learners explore the size and scale of dinosaurs. Learners listen to "The Littlest Dinosaurs" by Bernard Most to learn about the different sizes of dinosaurs.

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

Sharks: Taking a Bite Out of The Myth
Source Institutions
In this activity, learners will explore trends in shark populations using shark landing data from the National Marine Fisheries Service.

Solar System on a Stick
Source Institutions
Learners build a model of the planets in the solar system. In their model, the planets are spaced in their relative distance from the Sun.

Digging Deeper!
Source Institutions
In this activity, learners explore dinosaur skeletons and anatomy. Learners make observations about a T. rex skeleton diagram and then measure the skeleton length and width.

Bernoulli's Blowout
Source Institutions
In this quick activity (page 1 of PDF under SciGirls Activity: Kites), learners will witness firsthand the effects of Bernoulli’s Principle by capturing a ping pong ball in the stream of air created b

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.

Jump to Jupiter
Source Institutions
In this activity, learners help create and then navigate an outdoor course of the traditional "planets" (including dwarf planet Pluto), which are represented by small common objects.

Lift Off!
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Lift Off) is a full inquiry investigation into the engineering challenges of sending scientific sensors into space.

Bridge Building
Source Institutions
This is a quick activity (on page 2 of the PDF under Hockey Sticks Activity) about how the arrangement of carbon atoms determines carbon's different properties.

Space Jell-O
Source Institutions
Albert Einstein proved that space bends around anything that has mass. This activity uses Jell-O's ability to bend around objects as a model for space bending around planets and stars.

Water, Water Everywhere
Source Institutions
In this activity, learners estimate how much water they think can be found in various locations on the Earth in all its states (solid, liquid, and gas) to discover the different water ratios in the Ea
