Pine Cones and Seed Dispersal

The video explores how pine cones change in different environments, focusing on their role in seed dispersal. It begins with a nature walk where pine cones are collected, followed by observations of their changes indoors. An experiment demonstrates how pine cones open and close based on moisture, highlighting their adaptation for seed dispersal. The video concludes with a summary of these findings.

What did Squeaks find during the nature walk?

• Leaves

• Pine cones

• Animal tracks

• Rocks

Why do pine cones stand out in the snow?

• They are colorful

• They are large

• They are shiny

• They are brown against white snow

What happens to pine cones when they are brought indoors?

• They shrink

• They change color

• They become heavier

• They open up

What do the scales of a pine cone resemble?

• Tree bark

• Leaves

• Fish scales

• Feathers

Why do seeds need to travel away from their parent plant?

• To change color

• To grow faster

• To avoid predators

• To find more sunlight and water

What did the experiment with water demonstrate about pine cones?

• They change color when wet

• They open when wet

• They close when wet

• They grow larger when wet

Why do pine cones close up in wet weather?

• To protect the seeds from animals

• To keep seeds from getting wet

• To conserve water

• To prevent seeds from being carried by the wind

What part of the seed helps it travel in the wind?

• Its sail-like shape

• Its size

• Its color

• Its weight

What happens to pine cone scales in dry weather?

• They fall off

• They stretch open

• They close tightly

• They change color

Why is it beneficial for seeds to be dispersed far from the parent tree?

• To avoid competition for resources

• To change species

• To find new types of soil

• To grow larger
