on Science Penny Lab Conclusion
on The question investigated in this expirement was “How many drops of water can fit on one side of a penny?” It was hypothesized that “If I take an eye dropper and drop water on pennies, then the pennies will hold as much water as possible because of the surface tension and cohesion.” The result of this expirement proved my hypothesis was correct because the pennies did hold as much water as possible until there was way too much water on the penny and the mass of the water grew greater then the penny. The answer to the purpose of this expirement is that with just regular drops of water pennies can hold an average of 30.25 drops of water. When the water is tampered with and mixed with a soapy solution the Penny does not hold as much water. In the soapy solution tests the average amount of drops the penny could hold was 13.25.

on Float your boat science lab
on Name: Jake BLK:D
CHALLENGE: Make a boat that can float in water and hold the most amount of pennies.
PROBLEM: What is the best design to hold the most weight with the materials given above water
HYPOTHESIS: If I put pennies on my boat then the pennies will not sink
IDEA FOR ORIGINAL DESIGN:
My group chose this design because we think that the marshmallows will hold the boat up evenly and make it float while the crossed straws will give the tinfoil support.
HOW MANY PENNIES DID YOUR BOAT HOLD? My boat held 130 pennies
WHAT WOULD YOU KEEP OR CHANGE ON YOUR BOAT DESIGN IF YOU WERE TO DO THIS AGAIN? If I were to recreate my boat it I would make the walls of the boat taller so the water is kept out longer. I would keep the marshmallows on the 4 corners because the really helped the boat float.
