What could the dependent variables be in a brine shrimp lab??? ?

For science, I had to do a brine shrimp lad, and now I am doing a lab write up. In the write up, I have to state our group’s independent variable, which was a change in temperature for one of the jar’s water. I did that, but now I have to state the dependent variables. I know that it means the effects of the dependent variable, but I have no idea as to what they could be.

Please tell me examples of dependent variables for my lab. Thank you very much!!!

Which science research topic? (10 pts)?

i have a list of science research topics… do u mind letting me know which one is the most interesting or original and has the best chance to win the museum of natural history young naturalist award. PLEASE 10 PTS TO BEST IDEAS

and I’m also in 9th grade so make it sound like it thank you very much

Fairy Shrimp by God or Fairy Tale

Psalm 136:4 To him who alone doeth great wonders: for his mercy endureth for ever.” There are about 300 species of a delicate creature known as Fairy shrimp. Unlike the shrimp that might end up on your plate for dinner, Fairy shrimp are typically very small. Fairy shrimp usually live in pools of water that may dry up and remain dry for years. When the pool is dry, they exist as egg-like cysts, sometimes for years, before the rains begin to fill the pool. Early in 2005, biologists announced the discovery of a new species of Fairy shrimp swimming in two lakebeds of the Idaho desert. The new species is much larger than most Fairy shrimp, growing as long as three inches. It has spines on its front legs for capturing prey. While they look frilly and delicate, they prey on smaller Fairy shrimp. When the larger Fairy shrimp finds a smaller shrimp, it bites it to immobilize it. If it’s not hungry at the moment, it stores its catch by attaching it to velcro-like patches on it abdomen. A full-grown member of the new species can store up to four smaller shrimp for later use. The beauty of these Fairy shrimp is a testimony to God’s unlimited creativity. At the same time, its cannibalism is a witness to the effects of sin. We thank God that He has sent His Son, Jesus Christ, to save us from the ultimate consequences of our sin. Prayer: Thank You, Lord, for carrying my sin on the cross and bringing this Gospel to my ears and heart. Amen. Notes: Associated Press, 3/16/05, “New fairy

Is there something out there?

No, I’m not referring to the X-Files, extraterrestrials, UFOs and all that Science Fiction material. I’m referring to Sasquatch and probably other things we don’t know about that go bump in the night. Native American legend tells of a creature, a ‘wild man’ ,a tall hairy beast the name in which they gave to it Sasquatch. Tales and stories of Sasquatch range all over North America from Canada to Florida and in between, images of this creature has been found on rocks and cliffs..So how is it possible if many Native American groups described a similar creature if most of these tribes and nations were separated hundreds and thousands of miles apart and hardly have any contact with one another…It’s similar to the dragon, which ranges from East Asia all the way to Northern Europe and Central America so how can Sasquatch be part of the imagination if Native Americans throughout the modern-day United States and Canada describe a similar being? Is it possible that Sasquatch can exist since Science has only discovered and identified 2 million species of animals, and there is estimated to be 10 million species unknown, that is alot of possibilities..Enough to explain sea serpents, sea monsters and unknown creatures that can be hiding so why can’t Sasquatch exist if Science has only scraped the surface of this planet…the oceans and the most remote regions of this Earth. The Paterson Footage shows a upright creature walking through the California wilderness, then the animal turns and looks at the camera for a brief moment and then turned back and walked off deep into the woodwork. But the animal’s movements look non human, the only way to mimic the movements is to be exactly positioned as the animal it is not possible to move and walk as it did. The face looked real and in detail the ligaments could be seen working and movie, so I think it can’t be a man in a monkey suit. So could it be that since Science has missed 10 million species of animals, they are reluctant to believe in the existence of such a creature..

My little brother is obsessed with bugs, what’s a cool gift for him?

He is 6 years old and is absolutely obsessed with bugs. When he comes home from school, he immediately goes outside to play in the dirt. Are there any playsets or toys that will assist him while he does this. Maybe some kind of science kit. It is his birthday coming up and I want to get him something relatory to bugs, something like an ant farm or one of those sea monkey kits…
Any help would be greatly appreciated!
