# Giribaldi lake question

Square area of lake: 9940 m2

Avg Depth of lake: 119 m

9940×119=1182860 m3 of water

converted into liters: 1182860000l of water

1l of water = 1kg

so we have 1182860000 kg of water

or 1182860 tonnes of water

# Bubble Gum lab: video and Conclusion

Our conclusion was that the hubba bubba both stretched longer and blew larger bubbles before popping. this is likely due to it being more compact than the big league chew, meaning it could stretch out more. It was far more rigid and difficult to chew, and this was perhaps a factor in why we were able to draw it out longer, the reason for it’s density and hardness was likely a result of it being designed to withstand more pressure and therefore, blow larger bubbles. As blowing bubbles requires tensile strength, this also correlates to how much it can stretch before snapping. And the results correlate to this as well

size of bubbles:          attempt 1/2/3/avg

brand A (hubba bubba): 10 cm/7 cm/5cm/7.3 cm

length measured before snapping

length:

A: 280 cm
