It's a Gas!
Source Institutions
In this simple activity, learners see the production of a gas, which visibly fills up a balloon placed over the neck of a bottle.
Watching Crystals Grow
Source Institutions
Learners will compare the growth rate and appearance of crystals forming on small rocks to those growing on miscellaneous objects. Learners will also investigate how temperature (warm vs.
Formation of a Precipitate
Source Institutions
Learners create hard water by mixing Epsom salt and water. Then they compare what happens when soap solution is mixed with hard water and regular water.
Bready Bubble Balloon
Source Institutions
Learners discover the bubble power of living cells in this multi-hour experiment with baker's yeast. Learners make a living yeast/water solution in a bottle, and add table sugar to feed the yeast.
Water Clean-up
Source Institutions
This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.
Defining Density
Source Institutions
In this introductory demonstration and activity, learners are introduced to the concept of density as they explore a rock and a wooden block in water.
Changing the Density of an Object: Changing Shape
Source Institutions
Learners will see that changing the shape of an object, like a clay ball, that is more dense than water, can affect whether the object will sink or float.
Ball Bounce Experiment
Source Institutions
In this activity, learners investigate the properties of different types of balls.
Surface Area and Soda Geysers
Source Institutions
This is an activity (located on page 4 of the PDF under Surface Area Activity) about surface area and reactivity.
How Plants Grow
Source Institutions
In this biology activity (page 3 of the PDF), learners will explore how plants turn sunlight into food through a process called photosynthesis.
Solar Structures
Source Institutions
In this activity, learners explore how the power of the sun can be harnessed to heat and cool a building.
Rainbow Density Experiment
Source Institutions
In this colorful activity (page 6 of the PDF), learners will make a multicolor density column by using different concentrations of sugar solutions.
Funny Putty
Source Institutions
In this chemistry activity (page 1 of PDF SciGirls Activity: Milk Carton Boat), learners will create a blob of stretchable funny putty out of a water, borax, and glue mixture.
Measure the Speed of a Water Leak
Source Institutions
In this activity (page 2 of PDF under GPS: Glaciers Activity), learners will measure the rate at which water streams out of a leaky cup.
How Can Gravity Make Something Go Up?
Source Institutions
In this activity, learners use cheap, thin plastic garbage bags to quickly build a solar hot air balloon. In doing so, learners will explore why hot air rises.
Gas Production: Blow up a balloon!
Source Institutions
In this classic reaction, learners baking soda and vinegar in a soda bottle to produce carbon dioxide (CO2) gas. This gas inflates a balloon.
Ocean Acidification in a Cup
Source Institutions
Ocean acidification is a problem that humans will have to deal with as we release more and more carbon dioxide into the atmosphere.
Why Circulate?
Source Institutions
In this activity related to the human circulatory system (on page 10 of the PDF), learners observe the dispersion of a drop of food coloring in water, draw conclusions about the movement of dissolved
Good News: We're on the Rise!
Learners build a simple aneroid barometer to learn about changes in barometric pressure and weather forecasting. They observe their barometer and record data over a period of days.
Acid Rain Effects
Learners conduct a simple experiment to model and explore the harmful effects of acid rain (vinegar) on living (green leaf and eggshell) and non-living (paper clip) objects.
