Hey Now Science

Imagine this - a carbon atom that's part of you right now could have been part of a dinosaur millions of years ago! How cool is that? But how can this be possible? What's the BEST explanation for this fun fact?

• Is it because the carbon atoms in living things today are created when the organism is born?

• Or is it because the carbon atoms in living things today are the same ones that have always been part of life, just recycled over and over?

• Could it be that this isn't possible at all, because the carbon in our bodies couldn't have been part of any previous organism?

• Or is it because carbon atoms are passed down through generations, like a family heirloom, through the evolution of organisms?

Imagine you're a scientist exploring a beautiful hardwood forest filled with a variety of trees, other plant species, fungi, and animals. You have a device to measure the atmospheric carbon dioxide concentrations around the forest. You notice something interesting - the concentration is lowest right next to the forest and steadily increases as you move farther away from the forest. Can you figure out how this observation supports the Law of Conservation of Mass?

• Could it be that the total mass of the jar with sprouting seedlings will first decrease than increase compared to the original jar with seeds?

• Or maybe the amount of carbon burned by fossil fuels decreases further away from the forest?

• Could it be that the carbon released by plants through photosynthesis is quickly cycled through the cellular respiration of animals?

• Or is it that the carbon released into the atmosphere by decaying organic matter increases as you move further away from the forest?

Imagine Diana and Jane, two budding scientists, are conducting a super fun experiment. They are dropping balls of different colors and measuring how high they bounce back! But when they compare their results, they find a big difference. Can you guess the LEAST LIKELY reason for this difference in their data?

• Could it be because Diana and Jane dropped the balls from different heights?

• Or maybe, Diana and Jane used bouncy balls from different brands?

• Perhaps, Diana and Jane dropped the bouncy balls on different surfaces?

• Or, could it be that Diana and Jane conducted their experiment at different times of the day?

Imagine Tyler, a budding scientist, is on a mission to find the best fertilizer for his beloved St. Augustine grass. He conducts a series of exciting experiments with fertilizer A and B. After several trials, he discovers that his grass grows faster and thicker with the magical touch of fertilizer A. Now, how can Tyler ensure that his findings are as reliable as a compass in a jungle?

• Scientists are like magicians, they don't care about the results, they only want to know the secret behind the trick.

• By inviting fellow scientists to repeat his experiment, compare methods used, results obtained, and offer further explanations. It's like a science party!

• A scientist's findings can only become a Law if it is repeated 10 times. It's like a secret code in the world of science.

• Other scientists can compare methods and then copy your data if you used the same method. It's like sharing a secret recipe!

Imagine you're a tiny creature in a vast forest. Who would you be if you could harness the power of the sun to fuel your life?

• A consumer, munching on other organisms

• A producer, basking in the sunlight

• A decomposer, breaking down dead matter

• A scavenger, hunting for leftovers

Imagine you're a marine biologist studying a fascinating underwater food web. Suddenly, you notice a significant decrease in the fish population! What do you think would MOST LIKELY happen next in this aquatic drama? Here's a quick reminder of the food web: producer decomposer scavenger Mold Mangrove Leaf Gral Bacteria Prawn Fish Phytoplankton Heron Pelican

• The phytoplankton population would decrease.

• The mangrove tree population would increase.

• The pelican population would decrease.

• The heron population would increase.

Imagine you're a scientist, categorizing organisms into producers, consumers, decomposers, and scavengers. Can you guess what information you would need to sort these critters into their respective categories?

• Their favorite hangout spots in the ecosystem

• Their unique ways of producing offspring

• The specific resources they need to thrive and survive

• Their secret methods of obtaining energy for survival

Imagine you're a tiny aphid, living in a world full of dangers. Every night, your ant buddies invite you over for a sleepover in their cozy nest, safe from the scary predators. In return, you share your delicious honeydew with them. The next morning, they escort you back to your plant. What kind of cool symbiotic relationship is this?

• predation

• competition

• mutualism

• parasitism

Imagine you're a curious scientist conducting an experiment. You place 5 magical seeds on a wet paper towel and then seal them in a mysterious jar. You carefully measure and record the mass of this sealed jar in grams. Over the course of 2 adventurous weeks, you patiently wait for the seeds to sprout into tiny seedlings. Once they do, you measure and record the mass of the jar with the sprouted seedlings in grams. Now, can you tell which sentence BEST explains how the two masses will compare to one another?

• The total mass of the jar with sprouting seedlings will first perform a magic trick and decrease, then surprise you by increasing compared to the original jar with seeds.

• The total mass of the original jar with seeds will be less than the total mass of the jar with the sprouting seedlings, as if the seedlings gained superpowers!

• There will be no change in the total mass of the jar with seedlings after 2 weeks, as if time stood still.

• The total mass of the original jar with seeds will be more than the total mass of the jar with the sprouting seedlings, as if the seedlings went on a diet!

Imagine you're a scientist who has been on a bullfrog-watching adventure for many years. You've noticed something peculiar - these bullfrogs are now laying eggs 8 days earlier than they did 20 years ago when you first started your froggy journey! Not only that, but the trees around the pond have also grown taller and are casting more shade on the water than they did 20 years ago. What's the next step in your scientific adventure?

• Should you conduct more research to see if you can figure out why these frogs are changing their egg-laying schedule?

• Should you switch up your research and choose a different species of frog to study for the next 20 years?

• Should you conclude that the changed tree heights have somehow affected the frogs?

• Or should you assume that the water temperature must have risen, allowing frogs to lay eggs earlier?
