Mississippi Science BOT.5.4
The Standard
- BOT.5
- Students will explore adaptations that allow plants to survive in various habitats.
Enrichment: Use an engineering design process to design and build a plant model based on extreme environment criteria to overcome the difficulties presented by this environment. Identify revisions to the proposed model over time. *

What This Standard Means
What Students Need to Do
- Students design and build a plant model for a harsh habitat, such as a dry desert. They test how well it handles a set problem, then change the model based on the results.
What Mastery Looks Like
- A student can explain what each model part does, such as how a waxy leaf limits water loss. They record a test result, revise one feature, and test again to see if it helped.
Common Misconceptions
- Students may assume more leaves always help a desert plant, even though leaves can increase water loss. They may call a color change a revision or claim a design works without testing it.
How to Assess It
- Exit ticket: Your model lost 3 g of water in a fan test, but the limit was 1 g. Sketch one change and explain how you would test it.

Ways to Teach It
Build paper-towel leaves with and without wax-paper covers, wet each with 5 mL, weigh them, run a fan for 20 minutes, and weigh again.
Ask students to write: Would smaller leaves or a waxy coating better help your model keep water in the fan test, and why?
Play a card game: pair desert problems with root or leaf features, then swap one feature after drawing a failed test result.
Show photos of a saguaro and an agave; have students label how each limits water loss and choose one feature for their model.
