All objects ________ when a contact force is applied to them.

Bend/ Change Shape

100

Cups with more of THESE are able to keep liquids inside the cup both hot and cold better.

Walls

100

The process by which plants use sunlight, water, and carbon dioxide to make food (sugar) and oxygen is called...

Photosynthesis

100

This is an alternative to Palm Oil that grows in the United States.

Soybean, Canola

100

Changes in THIS process may be related to why different places have different amounts of water vapor in the atmosphere.

Evaporation.

200

The amount of the an object can bend before it is permanently deformed.

Elastic Limit

200

Even when the cup had a lid, the liquid still cooled down and heated up to match the room temperature. Why?

Heat was transferring through the cup wall

200

 Plants can't get their food molecules directly from this source, though it does contain some parts that can be used.

Water

200

While orangutan populations decrease, populations of these animals actually increase with more palm trees.

Rats, Snakes, Pigs

200

These 2 gases are increasing in the atmosphere at a high rate and are linked to global warming.

CO2 and Methane.

300

When an object is moving faster, it has more of this type of energy.

Kinetic

300

This type of matter has very little space in between the molecules but can still move freely.

Liquid

300

All plant foods we studied contain these building blocks, though not all plants have the same ones. Examples include carbohydrates, fats, and proteins.

Food Molecules

300

Palm Oil requires these 3 growing conditions.

Lots of sunlight, precipitation, and warm weather.

300

These 2 gases are released as a result of burning fossil fuels.

Water vapor and CO2

400
I am the force that acts on an object in the opposite direction of its motion as the object falls to the floor.

Air Resistence

400

The process by which water molecules leave a liquid and enter a gaseous form.

Evaporation

400

These tiny openings on a leaf's surface allow gases like carbon dioxide to enter and exit the plant.

Stomata

400

This is a way that organisms can interact with each other, although it may mean there is less food for one organism and more for the other.

Competition

400

What is the natural process that removes CO2 from the atmopshere.

Photosynthesis

500

3 features that determine how much an object deforms and when it breaks.

Material, Thickness, Shape.

500

A cup with an airtight lid is a good example of this type of system.

Closed System.

500

This organelle is where photosynthesis occurs.

Chloroplast

500

Although there are many individual squirrels in Boston Common, there is not much variety of species there. This is an example of a place with low ____________ .

Biodiversity.

500

Simply cutting emissions in half won't halve the temperature increase.  To reach equilibrium, emissions would need to be cut by how much? (in gigatons)

9 gigatons (+/- 1 gigaton)
