4/21/14 WARM UP

1. Grab folder2. Grab clicker3. Pull out blank piece of paper,

label it “Human Impact”

1. Two skydivers of different masses jump out of a plane at the same time. Not considering air resistance, which one will be falling faster?

a. the person with the bigger mass b. the person with the smaller mass c. they fall at the same speed d. there’s not enough information

2. What happens to the speed of the falling skydivers as they get closer to the ground?

a. they speed upb. they slow downc. their speed stays the samed. their speed is constantly changing

3. Which of the following is correct about the skydivers as the plane flew higher?

a. The force between the skydivers and Earth increased thus increasing their weight

b. The force between the skydivers and Earth decreased thus increasing their mass

c. The force between the skydivers and Earth decreased thus decreasing their weight

d. The force between the skydivers and Earth increased thus decreasing their mass

Mass vs. Weight

MASS

How much matter is in an object

WEIGHT

The force of gravity acting on an object

5. Suburban Sprawl & Deer

• What is it: When people build communities right on the

edge of a natural habitat for a species – then many species will start to come into the developed land

• Issue:• What to do?
