Shake out handkerchief and place one handkerchief in each glass 5.
How does temperature affect viscosity? NOTE if you actually have more than one hour, then also learn about how viscosity affects very small organisms like phytoplankton and fish larvae and think about how global climate changes could impact the viscosity of the oceans and what that might mean for marine ecosystems.
Fill the glass container with maple syrup, put container in pot with about 3 inches of water; do not turn on heat yet. Drop in one penny and time use stop watch how long it takes to hit the bottom of the container, listen for the sound of the penny hitting the glass.
Repeat 2 more times making sure you drop the penny from the same height each time; record data in a table. Every 2 minutes drop in another 3 pennies one at a time, timing each one. If you have a thermometer, you should also record the actual temperature.
In this case, time is easier to measure than temperature because where the thermometer sits in the maple syrup will affect your temperature reading. Make a table showing Heat Time 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, etc. Then make a column for the average fall time.
Graph the average fall times for each heat time data point. If you took real temperatures, make a second line graph with Temperature on the x-axis. What does the line look like?
Is it straight or curved? If you did both are the two lines the same or different? Now you must accept or reject your hypothesis. So determine if the data match your hypothesis.
If yes, then accept. If no, then reject. Does the line go up? Is that the hypothesis you chose? Then accept your hypothesis, otherwise reject it.
Does the line go down?Shree Bose: Google Science Fair's first Grand Prize Winner Andrew Federer In honor of Google's announcement of the 15 finalists for its Science Fair, we compiled our list of the most wild.
Join us in sharing your best idea using science, technology, engineering, and math. Scientific American is the essential guide to the most awe-inspiring advances in science and technology, explaining how they change our understanding of the world and shape our lives.
Open science is the movement to make scientific research, data, and dissemination accessible to all levels of an inquiring society, amateur or professional. Open science is transparent and accessible knowledge that is shared and developed through collaborative networks.
It encompasses practices such as publishing open research, campaigning for open access, encouraging scientists to practice. VIRTUAL SCIENCE FAIR ENTRY. Using common laundry stains of coffee, make up and ketchup I set out to learn which laundry detergent, Tide, Gain or Ultra Laundry Detergent worked the best at cleaning white handkerchiefs.

Abstract. A water bottle rocket is a rocket made out of a 2 liter bottle. It uses a launcher made out of pvc pipe or a rubber stopper, to launch the rocket into the air.
