Water on the Move: Wind and Waves
Source Institutions
In this simple activity, learners explore ocean waves. To find out if water moves forward toward the shore, learners create waves in a simulated ocean (small aquarium tank of water).

Changing the Density of an Object: Adding Material
Source Institutions
Learners see that a can of regular cola sinks while a can of diet cola floats. As a demonstration, bubble wrap is taped to the can of regular cola to make it float.

Natural Selection Because of Different Color: Camouflage
Source Institutions
In this activity (p.5-6 of PDF), learners investigate natural selection. Learners discover that natural selection, which takes place over decades, can lead to altered populations within a species.

Balloon Kebabs
Source Institutions
In this demonstration, learners observe the effects of density and pressure by attempting to make "balloon kebabs." Learners will try to insert a wooden skewer all the way through an inflated balloon

Cutting it Down to Nano
Source Institutions
This simple activity uses paper and scissors to convey two key concepts to learners: the nanoscale is very small and working on the nanoscale requires special tools.

Soda Pop Cave
Source Institutions
In this geology activity (page 6 of the PDF), learners explore how carbonic acid can slowly dissolve limestone and form caves.

Finding the Carbon in Sugar
Source Institutions
In this activity about combustion and energy, learners observe a burning candle in a sealed jar and the burning of white sugar.

Turning the Air Upside Down: Warm Air is Less Dense than Cool Air
Learners cover a bottle with a balloon. When they immerse the bottle in warm water, the balloon inflates. When they immerse the bottle in a bowl of ice, the balloon deflates.

The Wander of Pollen
Source Institutions
In this activity/demonstration, learners explore pollen and how insects and animals transport pollen. Learners investigate and compare wind and animal pollination.
Dollar Bill Grab
Source Institutions
In this demonstration, learners observe as two cola bottles and a dollar bill are arranged in a specific order: one bottle, upside down and filled with water, is placed on top of another bottle, with

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
Build A Hydrometer
Source Institutions
In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.

Inverted Foucault Pendulum
Source Institutions
In this demonstration, learners explore a variation of a Foucault pendulum, but upside down.

Conduction Countdown
Source Institutions
In this quick SciGirls activity (page 1 of the PDF under SciGirls Activity: Doghouse Design), learners will be introduced to the concept of thermal conductivity.

Acid Rain
Source Institutions
In this chemistry demonstration, acid rain is simulated in a petri dish.

Enzyme Action
Source Institutions
In this activity that can be used as a lab or demonstration, learners use Lactaid® and lactose to demonstrate the concept of enzyme action.

Shake and Make: Charge Recognition
Source Institutions
In this activity (page 10), learners explore how molecules self-assemble according to forces of attraction and repulsion.

Canned Heat
Source Institutions
In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

Burning Issues
Source Institutions
Learners use a candle to investigate the products of combustion. When a glass rod is held over a lit candle, the candle flame deposits carbon on the rod.

The Egg Activity
Source Institutions
Learners observe the outside and inside of raw chicken eggs, record descriptions, and hypothesize what will happen when a facilitator drops an egg on the floor.
