Simulation of Laparoscopic Surgery Lab
Source Institutions
This simulation of laparoscopic surgery enables learners to practice and to learn this modern surgical technique.

Human Impact on Estuaries: A Terrible Spill in Grand Bay
Source Institutions
In this activity, learners make a model of a pollution spill that occurred at Bangs Lake in Mississippi and measure water quality parameters in their model.

Whale Cart
Source Institutions
In this activity, learners interact with whale artifacts such as replicas of skulls, bones, teeth, and baleen (hair-like plates that form a feeding filter).

Writing for Night Vision
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Forensics), learners will use a home video camera with a “night vision” mode to test how various inks appear outside the spectrum of visibl

Laser Projection Microscope
Source Institutions
In this activity, learners use a laser pointer to project a microscopic image of a liquid sample suspended from the tip of a syringe.

Molecular Menagerie
Source Institutions
In this activity, learners use molecular model kits to construct familiar molecules like lactose, caffeine, and Aspirin.

Racing with the Sun: Creating a Solar Car
Source Institutions
Learners use engineering design principles to construct and test a fully solar-powered car. Solar car kits usually include a photovoltaic cell and motor; some include a chassis as well.

Shark Cart
Source Institutions
In this activity, learners touch and observe skulls of sharks and rays to learn about their diversity (over 400 species of sharks alone!).

Heart of the Matter
Source Institutions
In this activity, learners explore the concept of valve operation and how engineers have adapted valves for use in mechanical heart valve design.
The Water (Hydrologic) Cycle: Transpiration
Source Institutions
In this lab, learners grow broad bean (also called fava bean) plants in three EarthBoxes for a few weeks before exposing one to wind (using a fan), another to heat (using a lamp), and the third to not

Pickle-oh!: Musical Pickle Instrument
Source Institutions
What's a Pickle-Oh? Two pieces of pickle on a stick are connected to a Pico Cricket (micro controller). When you slide the pickles apart the note changes.

Forensic Science: Hair Sample Investigation
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Forensics) is a full inquiry investigation into how hairs from a crime scene are matched to suspects.

Low-Tech Water Filter for High-Impact Clean
Source Institutions
In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.

Make a Cast of a Tyrannosaurus rex Fossil
Source Institutions
In this activity, learners explore dinosaur fossils by making cast models of a T. rex. First, learners read about and research how dinosaur fossils form.

Waterhouse Hawkins and the Nano Dinosphere Museum
Source Institutions
In this activity, learners explore dinosaurs and fossils by creating a diorama.

I Spy, Describing Insects
Source Institutions
In this activity, learners observe and describe the physical and behavioral characteristics of insects, including crickets.

Exploring Structures: Butterfly
Source Institutions
In this activity, learners investigate how some butterfly wings get their color.

Runaway Runoff
Source Institutions
When it rains, water can collect on top of and seep into the ground. Water can also run downhill, carrying soil and pollution with it.

Off Base
Source Institutions
In this activity, learners explore the factors that tend to resist changes in pH of the ocean and why the ocean is becoming more acidic.

Delicious Smelling Chemistry
Source Institutions
In this activity, learners use household materials to investigate and explore their ability to smell an odor.
