Zoologic 2017-5: More Creatures Great and Small
Four new baby animals (an Aardvark, a bat, a coyote, and a mouse) arrived at the zoo infirmary for care before they join the exhibit housing the rest of their species. Each type of animal has a juvenile name and a group name. Please identify the juvenile name, the animal type, and the group name based on the clues below.
1. The young mouse kept escaping its hospital pen to explore the lab; it is no wonder several mice are called a "mischief."
2. The cub has many similar features--the snout of a pig, rabbitlike ears, and a kangaroo tail—yet the "earth bear" is related to none of these animals.
3. The whelp scratched the side of its clear plastic basinet in the night, trying to get at the pinkie; the young predator joined its band the next day.
4. The veterinary intern collected the young bat from the floor of the zoo's artificial cave where the rest of the cloud roosted.

Zoologic 2017-4: All Creatures Great and Small
Four new baby animals (a ferret, a hare, a hedgehog, and a platypus) arrived at the zoo infirmary for care before they join the exhibit housing the rest of their species. Each type of animal has a juvenile name and a group name. Please identify the juvenile name, the animal type, and the group name based on the clues below.
1. Even at only a week old, the kit was alert. It would watch every movement of the hare until the veterinary intern moved their plastic basinets to opposite sides of the lab.
2. The hedgehog juvenile would roll into a ball when startled; the lab assistant would sing softly to the "prickly piglet" to calm it down.
3. The leveret's eyes opened and fur developed quickly so it was the first to be able to join its drove.
4. The little puggle was a favorite of the hospital staff because it was such an unusual creature with its duck bill and paddle-shaped tail.
5. The young ferret was so active, it was obvious to the veterinarian why a group of them is called a "business."

Zoologic: Feeding Time!
Four friends (Marilyn, Nancy, Rosemary, and Teresa) arrived at the zoo at 1:15 to watch the animal feedings (of Hawks, Koalas, Sea Lions, and Tigers) at 1:30, 2:30, 3:30, and 4:30. They each had their favorite animal, but they all stayed together for the day and left when the zoo closed at 5:00.
Please identify the person, their favorite animal feeding, and the time based on the clues below.
1. Nancy, a Clemson fan, made it clear she was only there for the tiger feeding.
2. She had to wait until two hours after the sea lion feeding.
3. The koala feeding almost put her to sleep two hours before the last feeding of the day.
4. Teresa was fascinated by the hawks.
5. Marilyn got so close to her favorite feeding she got splashed by water; her clothes were still damp when they went to the Australia exhibit.
Zoologic: Giraffes
Four giraffes at the zoo (Angrit, Jebedah, Morutana, and Zakita) come from four different regions of Africa (Botswana, Chad, Somalia, and Tanzania) and are four different heights (10, 11, 12, and 13 feet tall). Please identify the giraffe, their native country, and their height based on the clues below. Please note that you cannot use the photos to decide about their heights because they were taken at different times, places, and distances.
1. Zakita is 1 foot shorter than the giraffe from Tanzania.
2. Morutana came from Somalia.
3. The one that is 10 feet tall is either the giraffe from Botswana or Jebedah.
4. The giraffe from Tanzania is 1 foot shorter than Angrit.
5. The 12 foot tall giraffe is from Chad.
1. Zakita is 1 foot shorter than the giraffe from Tanzania.
2. Morutana came from Somalia.
3. The one that is 10 feet tall is either the giraffe from Botswana or Jebedah.
4. The giraffe from Tanzania is 1 foot shorter than Angrit.
5. The 12 foot tall giraffe is from Chad.

Zoologic: Art at the Zoo
Young artists Avery, Blakely, Charlie, and Dorothy spent the afternoon at the zoo. Each selected one exhibit (the aquarium, the bird aviary, the mammal trail, or the reptile serpentarium) to inspire their art (clay sculpture, digital photography, pencil sketches, and watercolor painting). Can you match the artist, their media, and their inspiration?
1. Zoo visitors kept looking over Charlie’s shoulder at the sketches.
2. The watercolor artist thought her work portrayed the shimmering scales of the reptiles quite well.
3. Avery never went anywhere near the aviary; she read that some parrots like to eat clay.
4. Dorothy’s digital photos caught her subject’s bright colors and the shapes of their wings in flight.
5. One of the pencil sketches of a shark won honorable mention at the state fair that fall.

Logic Puzzle: Pet Shop Girls
Three friends, Cindy, Lisa, and Tanya, wanted to get pets. Their parents agreed they were responsible enough to adopt one animal each and drove them to the rescue center to meet the animals.
After playing with several animals, each friend chose a different type of animal from the others--a cat, a dog, and a parrot. They gave them three names--Fluffy, Rex, and Tutu, but not necessarily in that order.
1. The girl who adopted the dog did not name it "Tutu."
2. Lisa's pet, "Fluffy," does not have feathers.
3. Rex, who is not a dog, was adopted by Tanya.
4. The parrot was not adopted by Cindy.
Can you identify the friend, the type of pet, and the pet's name? You are welcome to use the sprites on Scratch or the Google Drawing table to help make your deductions.

Logic Puzzle: Time and Talents
Three siblings are all musically and physically talented. Each child has a private music lesson and a private sports lesson each day. Music lessons are offered at 3:30, 4:00, and 5:30 pm at the conservatory, while sports lessons are offered at the field house at 4:30, 5:00, and 6:00 pm.
Betty's saxophone lesson is 60 minutes earlier than Nadine's tennis lesson, but Betty's swimming lesson is 30 minutes later than Nadine's trumpet lesson. Also, Everett's guitar lesson is earlier than Nadine's tennis lesson, and Everett's golf lesson is 60 minutes earlier than Nadine's music lesson.
Can you help get the children to their practices in time by identifying the children, lessons, and times correctly?
