The twilight zone is a layer of water that stretches around the globe, just beyond the reach of sunlight and beyond the limit of photosynthesis in the ocean.
Watch this video about the amazing creatures that call the twilight zone home.
Choose 2 prompts below to show your thinking and learning after watching this video.
You just bumped into a friend who wants to know what a hatchetfish is. Describe this creature to your friend using MANY details from the video.
Do some research about the fangtooth mentioned in the video. Record what you learned in an interesting manner.
The anglerfish has a bioluminescent lure. Do research to find 10 other animals that are bioluminescent.
What is so unique about the dragonfish?
Life in the twilight zone looks weird or even frightening to us, but these animals have evolved to survive, and even thrive, in conditions that we could never hope to endure. What are some of the ways twilight zone animals might think we look weird or even frightening?

Each year humanity produces roughly 400 million tons of plastic, 80% of which is discarded as trash. Of that plastic waste, only one-tenth is recycled. 60% gets incinerated or goes into the landfills, and 30% leaks out into the environment. Fortunately, there are microbes that may be able to take a bite out of this growing problem.
After watching this video, answer these questions in an interview format. You are the interviewer and the interviewee is a plastic starfish.
How are man made polymers different than those found in nature ?
What are some common forms of plastic?
How do you break plastic’s chemical bonds?
What never before identified bacteria was found in the lab from this video.

When it is cold outside you can LEARN! Check out these Cold Weather Science Experiments and figure out if it’s real or a myth! Don’t forget to share your results!
Freezing Soap Bubbles: Head outside with some bubble solution and blow some bubbles! NOTE: Try heating up the bubble solution in the microwave beforehand. You can make your own bubble solution with 2 cups of water, half a cup of dish soap, and 2 teaspoons sugar.
Banana Hammer: Hang a banana outside for a few hours and it will freeze solid-solid enough for you to be able to hammer actual nails with it.
Make An Ice Thrower:Fill a Super Soaker with boiling water and then shoot it out into the cold. When very hot water meets very cold air, the water vaporizes, turning it into ice crystals…essentially, homemade snow. Don’t have a Super Soaker, just use the pot you boiled the water in.
Freeze-Fry An Egg: Don’t actually eat it, but leave a frying pan outside for about 15 minutes and then crack an egg into it. What happens?
After spending some time at the playground, soccer field, or in the backyard, it can be easy to see the dirt on our hands.
What you can’t see are the invisible-to-your-eye germs that accumulate on your hands throughout the day. To see the effect those germs have, give this this eye-opening experiment a try.
HAND HYGIENE EXPERIMENT
What you’ll need:
Three slices of bread (the kind from a bakery or homemade works best — the fewer preservatives the better)
Three resealable bags
Label each of the three bags:
Place one slice of bread in the “control” bag without touching it. You can use clean tongs, or turn the resealable bag inside out and use it like a glove to get the slice inside. Seal the bag.
Remove a second slice of bread and have your child touch the bread with her unwashed hands. Place the bread in the bag and seal it.
Have your child wash her hands with soap and water.
Take a third slice of bread and have your child touch the bread with her freshly-washed hands. Place the bread in the bag and seal it.
Take all three sealed bags and put them in a cool, dry place.
Look at the bread daily and write down your observations, but do not take the bread out of the bags. In a few days, mold should start to appear. What slice of bread gets moldy first? Which grows the most mold? Which grows the least? If mold starts to appear, have your child take a ruler and measure it and record your observations. You can even draw a picture of the bread each day, or keep a photo diary by taking pictures of the bread each day to watch the changes over time.

When Should I Wash?
“You should wash your hands before, during, and after preparing food. Also wash before you eat, after using the restroom, after blowing your nose, after touching animals, and any time your hands appear dirty,” says Terri Stillwell, MD, Associate Hospital Epidemiologist at Mott Children’s Hospital, where she is responsible carrying out various roles for infection control and prevention. Dirty hands can spread all kinds of germs from the common cold to food poisoning to more serious illnesses.
How Do I Wash?
Most of us do not properly wash our hands. The Centers for Disease and Prevention (CDC) recommends a multistep process:
Wet your hands with clean, running water (warm or cold), turn off the tap, and apply soap.
Lather your hands by rubbing them together with the soap. Be sure to lather the backs of your hands, between your fingers, and under your nails.
Scrub your hands for at least 20 seconds. Need a timer? Hum the “Happy Birthday” song from beginning to end twice.
Rinse your hands well under clean, running water.
Dry your hands using a clean towel or air dry them.
“The scrubbing part of washing your hands is important. It’s the combination of the friction of rubbing your hands together along with the soap that really gets them clean. Take your time and sing or hum the Happy Birthday song twice,” says Dr. Stillwell. If soap and water are not available, Dr. Stillwell recommends using an alcohol-based hand sanitizer. “Make sure it’s at least 60 percent alcohol. Rub the sanitizer all over your hands just like if you were scrubbing your hands with soap and water. Then allow the sanitizer to dry.”
