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?

Why do you think it's super cool for scientists to not just share their awesome findings, but also their step-by-step process with their fellow lab-coat buddies?

• Scientists are not really into results, they're all about the process, right?

• So that other scientists can recreate the experiment, compare the methods used, results achieved, and maybe even add some extra insights.

• A scientist's discovery can only reach the status of a Law if it's repeated 10 times, isn't it?

• Other scientists can compare methods and then just copy your data if you used the same method, isn't that so?

Imagine you're a group of young scientists conducting experiments to find out the percentage of oxygen in the air. Suddenly, you realize that each group has come up with different conclusions. What's your next move, Einstein?

• Do you tweak your data to match the known percentage of oxygen in the air?

• Do you calculate the range between the highest and lowest percentage found?

• Do you compare the methods used and identify possible errors?

• Or do you hold a vote on the group with the best procedure and copy their results?

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!

Consider a scenario where young scientist, Tania, is conducting an experiment to understand the impact of different liquids on rocks. She chooses chalk as her 'rock' and uses orange juice, soda, and milk as her 'liquids'. She follows the steps below: 1. She places a 3 cm long piece of chalk in three different beakers, one in each. 2. She pours soda into one beaker, orange juice into the second, and milk into the third. 3. After waiting for 2 minutes, she removes the chalk and measures how much of it remains solid. 4. She repeats this process three times. Based on Tania's experiment, can you identify a potential flaw that might affect the accuracy of her results?

• Is it because her experiment doesn't explain how she came up with this interesting idea?

• Should she have used larger pieces of chalk for a more noticeable effect?

• Is her experiment too brief and needs additional steps?

• is it because her experiment doesn't specify the exact quantity of soda, orange juice, and milk she should use in each beaker?

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.
