In this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle.

In this activity, learners create a "mini sky" in a glass of water in a dark room.

In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.

Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.

In this activity, learners build edible models of Jupiter and Earth to compare their sizes and illustrate the planets' internal layers.

In this activity, learners use gumdrops and toothpicks to model the composition and molecular structure of three greenhouse gases: carbon dioxide (CO2), water vapor (H2O) and methane (CH4).

In this activity, learners investigate carbon sequestration by creating a carbonated beverage out of apple juice and dry ice.

In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.

In this activity, learners build a simple solar oven out of household materials to melt chocolate and marshmallow between graham crackers--known as s'mores.

In this activity, learners compare and contrast their own skin (including the area covered) with that of an orange.

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

In this cooperative learning activity, learners visit ten stations and are challenged to think critically about various conservation questions and issues.

In this activity, learners explore the different salinities of various sources of water by taste-testing.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

Learners develop an understanding of air pressure in two different activities.

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.
