Examining the Heart
Source Institutions
In this activity about the heart (on page 22 of the PDF), learners examine sheep or chicken hearts to learn about the heart's structure and the flow of blood through the heart.
Colors of Stars
Source Institutions
In this activity, learners observe colors in the flame of a burning candle to explore connections between matter, light, color and temperature -- basic concepts of matter and energy.
That's the Way the Ball Bounces: Level 2
Source Institutions
In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, volume, density, and bounce height.
What is Energy?
Source Institutions
In this exploratory activity, learners experiment, observe and determine how various toys change from one form of energy to another.
Modeling Tidal Action
Source Institutions
In this activity (Lesson 1), learners work in groups to create tide simulations.
Can Energy be Created or Destroyed?
Source Institutions
In this activity, learners explore conservation of energy by experimenting with a solar cell light device.
Tomb Mapping
Source Institutions
In this activity, learners examine the culture and history of the tomb site.
Observing Different Microbes
Source Institutions
In this activity, learners use a microscope to examine three different microbes: bacteria, yeast and paramecia. Educator will need to prepare the yeast solution one day before the activity.
Counting Your Lucky Stars
Source Institutions
In this activity, learners sample a star field to estimate the number of stars in the universe.
Looking Back Through Time
Source Institutions
In this activity, learners create their own archaeological profiles.
Sound Automata
Source Institutions
In this activity, learners build their own sound machines and explore the interplay of motion and sound.
Invent a Plant
Source Institutions
In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.
Tube Zither
Source Institutions
In this activity, learners explore sound by constructing tube zithers, stringed instruments from Southeast Asia and the South Pacific.
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.
Three Little Pigs
Source Institutions
In this activity, leaners explore building techniques by recreating the story of The Three Little Pigs.
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
Let's Look at Water & the Scientific Method
Source Institutions
This activity has learners observe water and compare it to other liquids.
Crime Scene Investigation (CSI) with Powdery Mildew Fungi
Source Institutions
This exercise can be used to stimulate the investigative nature of learners as they use forensic plant pathology techniques to prove the learners' innocence in a mock murder investigation.
Fossil Age Estimation Model
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Dinosaurs), learners will model how paleontologists estimate the age of fossil discoveries by extracting “fossil” playing cards from newspa
Who Dirtied The Water?
Source Institutions
In this activity, learners receive a labeled plastic film canister containing a material representing a pollutant (i.e. pencil shavings = a beaver's wood chips).
