Spiderwebs subjected to high winds
Question:How strong are spiderwebs really?
Question: are spiderwebs strong becasue of the silk or because of the design of the web?
Question: What makes the tensile strength of spiderwebs so high?
Buoyancy
Drag
Pressure
Fighting Gravity
Harnessing Pressure: Propulsion
What is it?
How do rockets use pressure to their advantage?
Density

Activity Idea
-Have some way for the kids to create sounds and have them bounce through a layout
-blindfold and have locate an noise (could be unsafe)
-
Part of Grappling Hook
-Kids have to build a launching device (similar to a sling shot)
-Have to be able to aim towards a general area
-Should be re-launchable
-
Friction
(not doing)
Project Ideas
-Have the projectile launcher be able to aim towards specific targets
-Aiming towards some sort of wall that the hook part needs to grab on to
-Or instead it needs to knock things over
-Or instead it should pull items toward the kids
Question: What is the most effective method of having the hook portion of grab at a wall?
Design Portion:
-The launched projectile will be attached to a string so that once the hook grabs something the kids can pull which means the rope will undergo tension and the rope needs to be able to hold up to the challenge
Design Idea:
-The kids have to design the best hook or fastening device so that their grappling hook, when shot, will grab on to whatever the target is
-potentially make some sort of different things to add on to the hook, like tape or other things

Optimization:
What do we want/how do we get it?
Want to go fast
Want to float
Less Drag
More Buoyancy
Resistance to Motion
Hydrofoil design
Streamlining
Orientation
How does the shape of a car/boat/airplane help it go fast?
Why does it matter that vehicles travel in a certain direction?
Why is your arm pushed backward if you stick it out the car window?
Project Idea: task student with constructing an object using an understanding of buoyancy, drag, and pressure to allow it to float, move through water to a particular end (either to a particular location or simply as fast as it can), and be propelled forward using a balloon and straw, akin to a traditional balloon boat.
Question: how elastic is spider silk? how far can it stretch?
Brainstorming
Design Challenge Info
Design Challenge: The Hulk
Withstanding a Load
Withstanding a Wind Force
Withstanding a Shock
What other technologies use pressure to move an object? Is pressure use the same way in these as in rockets?
Just like an untied balloon flying around the room, rockets use an opening to release pressure. This pressure is used to generate a force called Thrust.
Can we use air pressure to push an object across the water?
