Luna is studying the unique features of spider silk for her biology project. She discovers that one particular feature allows the diving bell spider to create an underwater home. Which feature is it?

• Stickiness

• Waterproofness

• Color

• Stretchiness

During a nature expedition, Jackson observed how Darwin’s bark spiders use their silk. What did he discover?

• To glide through the air

• To build underwater homes

• To create large webs across rivers

• To paralyze prey

Abigail is working on a science project about spider silk. She needs to explain why gossamer silk is suitable for gliding. Can you help her?

• It is heavy and dense, providing stability.

• It is lightweight and fine, allowing it to catch the air.

• It is sticky, helping the spider adhere to surfaces.

• It is colorful, making it visible to predators.

Charlotte is studying the properties of spider silk in her biology class. What role do protein molecules play in determining the traits of spider silk?

• They provide color to the silk.

• They determine the features such as strength and stickiness.

• They make the silk waterproof.

• They help the spider glide.

Emma and Henry are observing different types of spiders. Compare the silk of a spitting spider to that of a diving bell spider in terms of their primary functions.

• Both are used for gliding.

• Both are used for building webs.

• Spitting spider silk is sticky for capturing prey, while diving bell spider silk is waterproof for creating underwater homes.

• Both are used for creating large webs.

Abigail and Oliver are working on a science project about spider silk. Why might they be interested in studying the silk of Darwin’s bark spiders?

• To understand how spiders glide.

• To learn about the protein molecules that make the silk strong.

• To discover new colors of spider silk.

• To find out how spiders build underwater homes.

David and Mia are studying spiders in different environments. Predict how the environment might influence the type of silk a spider produces.

• Spiders in windy areas might produce heavier silk.

• Spiders in aquatic environments might produce waterproof silk.

• Spiders in dark environments might produce colorful silk.

• Spiders in cold environments might produce sticky silk.

Avery and Evelyn are conducting a science experiment to test the strength of different types of spider silk. How should they proceed?

• Measure the color of the silk under different lights.

• Weigh the silk to determine its density.

• Use weights to see how much force different silks can withstand before breaking.

• Observe the silk under a microscope to see its structure.
