IMO, the 3 day camping trip isn't really the issue, making a "survival" video is the issue. Not being subject matter experts, making a survival video as a school project could be tough -- UNLESS, the video is about the process of actually learning survival techniques. Then if you fail to get a fire going using spark based techniques, you're demonstrating that it isn't as easy as some survival experts make it out to be on TeeVee. Talk about why it didn't work: not enough tinder, not enough spark, tinder is too wet to take a spark. When you do get a spark to catch, wave your arms like Tom Hanks on Castaway.

Start the clock and make that shelter from the sticks and brush in the area and when it's finished stop the clock (time lapse photography to show the shelter at various stages). It takes considerable time and energy.

Make some traps and put them out. Demonstrate how the traps work (Figure 4, deadfall, et al)

If you catch anything worthy of dinner you can consider yourselves very successful. Odds are every time you take the camera to check your traps they'll be empty.

You get the idea, document on video your attempts at learning the techniques, success's and more importantly the failures. It's all about the process.

Good luck.
