A s'more is a marshmallow that has been roasted over a fire then put between two graham crackers with a layer of chocolate. So many great things are synonymous with “summertime yummies!” We can’t think of a summer treat we enjoy quite as much as a s’more: warm, drippy chocolate oozing around a melted marshmallow and sandwiched in a graham cracker. A marshmallow is mostly sugar whipped with air to make it fluffy. PRINCIPALS: The Solar Oven works on the principle of converting sunlight to heat energy and retaining the heat for cooking. Renewable energy, usable energy derived from replenishable sources such as the Sun (solar energy), wind (wind power), rivers (hydroelectric power), hot springs (geothermal energy), tides (tidal power), and biomass (biofuels). One of these is the brown crust on the outside of a toasted marshmallow. To help you celebrate (slightly belatedly), Science World investigates what it takes to transform chocolate, graham crackers, and marshmallows into the sweet goodness of sâmores.

Wood contains hydrocarbonsâmolecules of hydrogen (H) and carbon (C). Ballot initiatives in Ohio and New Jersey … Also, it's why too much CO 2 makes Earth's temperature rise. According to the Consumer Energy Center, the clothes dryer (whichever type you have) is the second most energy-hungry appliance in the house -- only the refrigerator uses more power. Local elections can have a big impact on America’s energy mix and efforts to tackle climate change. Thermodynamicists (physicists who study heat conversion into other energy forms) call this “the greenhouse effect”—bad when it happens in the environment, but good inside a solar oven. ScienceU campers make pizza box solar ovens that can harness the sun's energy to make a s'more (melted chocolate and marshmallow between two graham crackers). This gives a marshmallow its form. The reaction also releases energy as heat and light. Donât worry if you missed it; itâs not exactly a well-known holiday. How might the S’mores change during the experiment? MAKE IT! These are molecules of hydrogen (H) and carbon (C). Did you know that August 10 was National Sâmores Day? A campfireâs heat causes the sugar and proteins in a marshmallow to chemically react. Hydrogen and carbon mix with oxygen (O) in the air to form carbon dioxide gas and water in the form of steam. "It's more potent than carbon dioxide. Itâs possible to use the heat from the sun to make a sâmore. The S&P 500 energy index was up more than 16% as of Friday morning, compared to last month.
