What is the force that can stop objects that are in motion? Friction
You throw a dart up in the air, and it moves downward toward the dartboard. What force caused it to drop downward? Gravity
What Force pulls objects downward toward the earth? Gravity
You are pedaling your bike downhill. What causes your speed to increase? Gravity
Two kids are sitting on a seesaw the same distance apart and have the same mass. The seesaw is balanced. What will make the seesaw move? One of the kids has to move forward or backward to create an unbalanced force?
You kick a soccer ball across a grassy field. Eventually it comes to a rest. What force caused it to come to a stop? Friction

What is weather? The condition of the atmosphere at a CERTAIN, SPECIFIC time and place
What is the characteristic of of all ecosystems which determines the plants, animals and weather in that ecosystem? Climate
Which weather instrument best predicts the amount of precipitation that will occur? Barometer -reads air pressure, low means lousy weather (precipitation) coming
Objects moving in a straight path are moving in what type of direction? Constant direction
How does air resistance affect the motion of the object. It reduces the objects speed (ex. A parachute slows down a skydiver)

What happens to an animal species when there are less predators? Animal population increases, which leads to competition, and eventually the population decrease because fewer can survive.
Where do plants get the food they need? Photosynthesis, they make their own food.
How does photosynthesis work? Plants take in carbon dioxide, sunlight and water and use it to create sugar (food) which they store, and oxygen which they give off.
