    What do bacteria use to move?

    • Flagella and cilia

    • Legs

    • They don't move

    • I don't care!

    Correct Answer
    A. Flagella and cilia
    Explanation
    Bacteria use flagella and cilia to move. Flagella are long, whip-like appendages that rotate to propel the bacteria forward, while cilia are shorter and more numerous, creating a coordinated beating motion. These structures allow bacteria to move towards food sources, away from harmful substances, and to colonize new areas.

    How many bacteria live in the entire world?

    • 14

    • 2

    • Too many to count

    • None, because I never get sick.

    Correct Answer
    A. Too many to count
    Explanation
    The answer "Too many to count" is the most logical and scientifically accurate response to the question. Bacteria are microscopic organisms that are present in every environment on Earth, including the air, water, soil, and inside living organisms. They are incredibly diverse and can multiply rapidly under favorable conditions. Given their ubiquity and ability to reproduce, it is impossible to accurately determine the exact number of bacteria that exist worldwide. Hence, the answer "Too many to count" is the most appropriate.

    True or False...Bacteria live in water.

    • True

    • False

    • I have absolutely no idea

    Correct Answer
    A. True
    Explanation
    Bacteria are microscopic organisms that can be found in various environments, including water. They can thrive in both freshwater and saltwater, and are present in oceans, lakes, rivers, and even in tap water. Bacteria play a crucial role in the ecosystem, breaking down organic matter and recycling nutrients. Therefore, it is true that bacteria live in water.

    True or False. Yogurt has nothing to do with bacteria.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    False. Yogurt is made by fermenting milk with bacteria, specifically Lactobacillus bulgaricus and Streptococcus thermophilus. These bacteria convert lactose (milk sugar) into lactic acid, which gives yogurt its tangy taste and thick texture. The presence of these bacteria in yogurt also provides various health benefits, such as improving digestion and boosting the immune system. Therefore, yogurt is directly related to bacteria.

    On the first day of the bacteria unit, where did we see bacteria?Hint: They like food too!

    • In our mouths

    • Under a microscope

    • In our shoes

    • Under the hamster's cage

    Correct Answer
    A. In our mouths
    Explanation
    Bacteria are commonly found in our mouths. This is because our mouths provide a warm and moist environment, which is ideal for bacteria to thrive. Additionally, bacteria can be found in plaque, which is a sticky film that forms on our teeth and gums. Therefore, it is not surprising to see bacteria in our mouths during the bacteria unit.

    How many layers of cloth does it take to filter dirty water into clean water?

    • One

    • None! Who needs clean water?

    • Six

    • It can't be done!

    Correct Answer
    A. Six
    Explanation
    The correct answer is six because multiple layers of cloth can help filter out impurities and particles from dirty water, allowing it to become cleaner. Each layer of cloth acts as a barrier, trapping larger contaminants and allowing cleaner water to pass through. By using six layers of cloth, the filtration process becomes more effective, resulting in cleaner water.

    What do humans have in common with bacteria?Hint: There is more than one correct answer

    • They both hate going to the dentist

    • They need water to live

    • They can smell bad

    Correct Answer(s)
    A. They both hate going to the dentist
    A. They need water to live
    A. They can smell bad
    Explanation
    Both humans and bacteria need water to live. Water is essential for cellular functions and metabolism in both organisms. Additionally, both humans and bacteria can smell bad. Bacteria can produce foul odors due to the release of waste products, while humans can have body odor due to sweat and bacteria on the skin. However, the statement "They both hate going to the dentist" is not a valid answer as it does not represent a common characteristic between humans and bacteria.
