The Triops - Boces

PACKET OF
Editable and Reproducible
Parent Letters
Blackline Masters &
Journal Pages
for SCIENCE 21 users
Grade Two Unit Three
Triops

Dear SCIENCE 21 User,
Several teachers have asked for a separate packet of
editable and reproducible documents that includes the
Parent Letters, Blackline Masters, and Journal Pages that
are a part of the SCIENCE 21 program.
The documents on this media are provided in MS
Publisher Format and may be used by SCIENCE 21
participants to print, adapt, and customize any of these
important components. For example, teachers often like
to reproduce the parent letters onto their school
stationery, or adapt worksheets for tiered activities or to
meet small group needs.
We hope that this new service will be useful to you and we
appreciate your support and comments.
Sincerely,
Abby B. Bergman
SCIENCE 21 Coordinator

Dear Family,
Date____________________
This next science unit is on life science. Your child will be studying plants
and a live animal. This unit is inquiry-based. Skills that are emphasized
include observing, classifying, measuring, collecting and interpreting data.
In this unit, the students will first observe the basic parts of a plant and an
animal called Triops. Then they will compare them to other plants and
animals.
Students will develop a positive attitude towards this animal by learning how
to care for it, determining it’s needs for survival, and setting up a habitat.
We look forward to some exciting experiences in school and hope you will
encourage your child to share them with you at home.
Thank you for your support.
Sincerely,

Dear Family,
In the Science 21 program, your child is studying a live animal called the
Triops. Triops are small crustaceans that look like miniature horseshoe
crabs.
In this unit, the students will observe the basic parts of the Triops and
compare it to other animals. As they care for the Triops, they will note
their behavior and responses to various stimuli. Students will develop a
positive attitude towards this organism by learning how to care for it,
determining it’s needs for survival and by setting up a habitat.
We look forward to some exciting experiences in school and hope you
will encourage your child to share them with you at home.
Sincerely,
69

NOA Onion Trivia Page 1 of 1
http://www.onions-usa.org/folders.gif.map?85,116
ONION TRIVIA
One of the world’s oldest cultivated vegetables, this member of the lily family
was considered sacred by ancient Egyptians, as valuable as gold in the Middle
Ages and a vital food for many historical military commanders on land and sea.
The onion has long been known as a symbol of eternity. Ancient Egyptian took
an oath of office with their right hand on an onion believing it to be a symbol of
eternity since the layers formed a sphere within a sphere. Byzantine
architecture uses the symbolic onion shape as a dome for many of their
religious structures.
During the Middle Ages, onions were so valuable, they were used as rent
payments and wedding gifts.
Christopher Columbus brought onions to the New World from Europe.
Flavorful and nutritious, they were a welcome addition to the first Thanksgiving
feast.
Captain James Cook applied the onion remedy in the eighteenth century for
scurvy on his voyages to remote areas of the Pacific. At one point, Cook
refused to sail until each man in his crew ate 20 pounds of onions followed by
10 pounds two days later.
During the Civil War, General Ulysses S. Grant sent an urgent message to the
War Department saying, “I will not move my army without onions.” The next
day, three trainloads were on their way to the front.

1. How do Triops swim?
Questions About Triops
Grade 2, Unit 3, Lesson 6, Blackline Master #3
When a Triops turns upside down, you can see how they swim. Triops use their trunk appendages.
If you look closely, you can see them beat in waves. The wave starts at the rear of the animal and
moves to the front.
2. What parts of the body do they use to move forward?
The trunk appendages help the Triops move forward when they are free swimming in the water.
When they are at the bottom, the trunk appendages “walk” along the gravel, just like when you
walk along the bottom of a swimming pool.
3. What other movements and behaviors can you see?
Triops spin and swim upside down. They twist their tails and move in circles. The carapace isn’t
flexible, but the rest of the body is. So, they can move in lots of different ways. They also like to
dig in sand and gravel. They bulldoze their way through a pile of sand, pushing with their carapace
against the grains. They move forward using the push of the trunk appendages.
4. What parts of the body are used to find food? What does a Triops do when it finds food?
When a Triops swims past a lump of Triops food, it often turns towards it. It can probably detect
chemicals from the food in the water (possibly with its first appendages). Then, it tends to turn
onto its back and grab the food with its trunk appendages. They move the food forward towards the
mouth. The front trunk appendages have bristles on them (you can’t really see these even with a
hand lens) which sieve food from the sand, gravel and water.
5. What parts of the body are used to eat food?
When the food reaches the mouth, you can see the mouth parts (mandibles) moving and chewing
the food.
6. What other body parts have you noticed?
The long, first appendages (that look like antennae), touch and feel the sand in front of the Triops.
The tail is long and flexible. It moves around a lot. Maybe it helps the Triops to steer when
swimming, like a rudder. It has 2, long points at the end.
The carapace is like a shell, covering the front half of the Triops. It looks like a shield, and
probably offers some body protection. It also helps push through sand when searching for food.
The carapace is quite colorful when the Triops get older, and can be bluish, green, brown, or
reddish.
Triops have 2 eyes. You can see them quite clearly as dark, kidney-bean shaped areas at the front
of the carapace. Between the eyes, there is a dorsal organ which can be seen with a hand lens. In
some species this looks like a third eye, hence the name Triops (three eyes). In mature Triops, you
may see the egg pouch. This looks like a small, white bag underneath either side of the body (like a
golf ball). The egg pouches are found where the carapace ends. You may see eggs if you look with
a hand lens. They are tiny, whitish - yellow dots in the pouch.

• How many molts the Triops goes through depends on how much food

• The life cycle may stop at the egg stage if the pond is dried up. It
starts again when it rains.

The Stages of Human Growth
Infancy:
• Babies grow rapidly in their first year.
• They grow 1” per month for 6 months.
