PVC Water Squirter
Source Institutions
In this activity, learners build a water squirter using a PVC pipe, dowel, and foam. This activity is great for the summer time and introduces learners to forces and water pressure.

Homemade Rain Gauge
Source Institutions
In this activity, learners will build rainwater collectors to practice meteorology in their own backyard. Collect and analyze data to determine how much rainfall you get in a set period of time.

Powdery Mildew Fungi: Classification and Ecology
Source Institutions
In this laboratory exercise, learners will discover how many different plant hosts they can find that are infected by the same genus of a powdery mildew fungus, or how many different genera of powdery

Discovery Time: Turtles
Source Institutions
In this activity, young learners (2 years and up) explore turtle basic adaptations and biology. Turtle external anatomy is explored by "building" a turtle with a nature collage.

Get Moving! Active Play Indoors and Outdoors
Source Institutions
In this activity, learners explore the importance of active play.

Creating a Soil Map
Source Institutions
In this activity, learners investigate soil conditions by creating a soil map. Learners record soil characteristics and compare the conditions of soil in different grid sections.

Cactus Wheel
Source Institutions
In this outdoor activity/field trip, learners explore the concept of population density.

Rocket Wind Tunnel
Source Institutions
In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

Solar System in My Neighborhood
Source Institutions
In this activity, learners shrink the scale of the vast solar system to the size of their neighborhood.

Lilliputian Landscaping
Source Institutions
In this activity, learners examine the different materials gardeners add to their soil, and discuss how these materials are important for plant growth.

Stargazing
Source Institutions
In this nighttime, outdoor activity, learners keep a record of what they see in the sky by drawing constellations, the Moon, and making note of the weather and conditions each day.

Pollen Tracks
Source Institutions
In this activity (on pages 30-36), learners simulate a dig for ancient pollen, to experience how paleobotanists study fossilized pollen in rocks to learn about early geological and climatological even

Thrown For A Curve: Pitch Like A Big Leaguer
Source Institutions
You may have tried to throw a curveball or a slider, or even a screwball, with an ordinary baseball and found it difficult to do.

A Spray Spree
Source Institutions
In this activity, learners explore water pressure by conducting an experiment with a garden hose. Learners build a testing apparatus and create PVC nozzles with different sized holes.

Science at the Waterpark!
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Water Slides) is a full inquiry investigation into speed and motion and takes place at a water park.

Solar Water Heater
Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

Determining the Amount of Transpiration from a Schoolyard Tree
Source Institutions
In this activity, learners calculate the number of milliliters of water a nearby tree transpires per day.

FlyBy Math: Distance-Rate-Time Problems in Air Traffic Control
Source Institutions
In this small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems.

It's the "Rain," Man
Source Institutions
In this weather forecasting activity, learners use common materials to construct a rain gauge and measure daily, monthly, and yearly rainfall.

Stepping Out: Hop, Skip, Jump
Source Institutions
In this activity, learners explore and experiment how we can use our bodies everyday to get from one place to another.
