Some people believe that the word turtle is another word for
tortoise. They believe that the two words are names for the
same animal, but that is not true. Turtles and tortoises are
related, and they are both reptiles. However, there are
differences between these two animals. Most turtles live in
salt water and can swim. They have hard shells and flippers
for swimming. Tortoises usually live on land. Land tortoises
have legs instead of flippers so that they can move on land.
Sometimes tortoises live in fresh water, but not in salt water
like turtles. The tortoises which live in freshwater have
webbed feet and sharp claws so that they can move well in
water and on land, as well. Both turtles and tortoises hatch
from eggs and both can grow to be very large. Both animals
have been around since prehistoric times.

a. Turtles and tortoises are related animals, but have differences
b. Turtles are animals that have been around since prehistoric
times

Table 1
Do you know that rules are everywhere? We have rules at home,
rules at school, rules at the store, and rules on the road! We have
rules for riding bikes, driving cars, flying airplanes, and even for
swimming. Why do we have so many rules? Well, for one thing,
rules help us know what to do. We know to stop at a red light and
to go when the light turns green. We know to use our indoor
voices in the lunchroom and save our outdoor voices for recess. At
the store we know the rule is to take our things to the checkout
lane before we leave the store! Rules help us do the right thing. We
know rules for fire safety. We know to dial 911 to report a fire or
to stop, drop, and roll if our clothes are on fire. We all know the
rule that we should never swim alone. Sometimes rules will change,
but they are almost always made to keep us safe and to help us get
along with others. Rules are important.

Table 2
Lighthouses are important to sea travelers. They have been
used for thousands of years to warn ships that they are near
land or dangerous rocks. Lighthouses are towers built near
the shore or among the rocks. They have a bright beacon of
light shining from the top. Long ago metal baskets with
burning coal or wood were hung from poles at the top of the
lighthouse to produce the warning light. Today a very large
lens shaped like a barrel sends a beam of light far out to sea.
Sailors learn where lighthouses are located. Each lighthouse
has a special signal so that sailors can tell them apart. The

also help the sailors stay on course.

a. Sailors watch for light houses

c. Light houses help sailors
Table 3
Plants add a lot to our world. Plants outdoors can make a
beautiful garden. They make a place for large and small
animals to make home. Plants indoors are pretty, too. In
the house live plants give off oxygen which people need
to breath. Maybe the most important thing about plants
is that you can eat them! Animals eat them, too! Think of
all the foods you eat in one day that comes from a plant.
The wheat that is in your cereal or bread is a plant! The
