Friday Recap

This week we built ships and sunk boats

The Goal: Sink a boat made from aluminum foil

in only 20 paperclips

Requirements

• It must float
• It must hold at least 20 paper clips
• but sink on the 21st paper clip

​

• 🚨🚨🚨 Hint🚨🚨🚨
• each paper clip weighs one (1) gram
• Water is equal to (1 gram) upward force.
• water is = to 1 (gram anti-gravity)

​

Density of water: Water’s density is 1 gram per mL because it was used as a reference point in the metric system. One liter of water (1000 mL) weighs 1 kilogram (1000 grams).

​

• Shape a boat from aluminum foil .05 grams equalizer (e.g., a small rectangular or bowl-shaped vessel).
• Float it in a container of water (e.g., a tub or bucket).
• Add 20-one gram paperclips one by one until the boat sinks.
• The goal is to calculate how much weight (in grams) the boat can hold, which relates to the volume of water displaced by the boat (in liters or cubic centimeters, since 1 cm³ = 1 mL = 0.001 liters).

One up...One down

Density of water: Water’s density is 1 g(ram)/mL because it was used as a reference point in the metric system. One liter of water (1000 mL) weighs 1 kilograms of water (1000 grams).
