Matter
Name the 3 states of matter
Solids, liquids and gases
Watch the experiment. Think about how forces always occur together. When there is one force, whether an object is still or moving, another force is always working in the opposite direction.
Which way did the air coming out of the balloon move?
It moved backward in the direction away from the carton.
Look at the picture.
What does the Cod eat?
Herring and smaller fish.
Look into the sky on a clear night and you may be able to observe the Moon, or part of it, lit up by the Sun. People can keep track of the Moon’s appearance from Earth in lunar calendars. This makes it easy to see how the appearance of the Moon changes over time. A student made the following lunar calendar for 16 days, but it was cloudy on several nights. A student is studying the partial lunar calendar. Which sequence of moon phases correctly represents the pattern in the appearance of the moon and completes the calendar?
C
The diagram shows four blocks of the same size in a water tank. Block Y has the same density as the water.

Air is a gas. What are some ways we can see air?
Some possible answers include: in a bubble, in a balloon, when it’s cold outside, bubbles in soda, etc.
Which way did the carton move?
It moved forward. It moved in the opposite direction of the air.
What eats the Cod?
The Shark eats the Cod.
The diagram shows a partial Sun-Earth-Moon system. The boxes represent the position of the moon at different times. Select the position on the model that represents the day 1 moon phase. Day one is also known as the new moon. When we have a new moon in our sky the moon can not be seen.
G
What are some examples of a solid in our classroom?
Some possible answers: desk, book, ruler, chair, pencil, etc.
Which force was the action force?
The air coming out of the balloon was the action force.
Where does the energy for this food chain come from?
The sun.
Which time of day does the Sun appear highest in the sky?
A. midnight
B. noon
C. sunrise
D. sunset
B- This is also known as the zenith
Experiment! Watch what is happening.
In this experiment, Where is the solid, liquid, and gas?
Baking soda is a solid
vinegar is a liquid
Carbon dioxide created from the chemical reaction is the gas. The gas is trapped in the balloon.
Which force was the reaction force?
The forward movement of the carton (boat) was the reaction force.
What is the smallest organism in this food chain?
The plant plankton.
Based on the graph, answer the following question.
Circle one word or phrase in each set of parentheses to explain a reason for the brightness data shown.
The Sun appears ( dimmer / brighter ) than the other stars because it is ( closer to Earth / farther from Earth / larger / smaller ) than the other stars.
Brighter
closer
Label the following pictures a solid, liquid, or gas?
Liquid, Gas, Solid
How is the force of air in the balloon like a propeller in a boat?
A propeller pushes backward against the water. This is like the air flowing out of the balloon. The water pushes forward just as it did in the experiment.
What would happen if all the plankton suddenly disappeared?
The plankton-eating animals would have nothing to eat and would die. This would cause all the animals in this food chain to eventually die.
Which letter shows summer in the northern hemisphere?
D
