    So your rest break is over. Answer this question.... Max wants to teach his dogs, Duncan and Gigi, the scientific method. What are the steps?

    • Ask questions,collect info,form hypothesis,plan an experiment,conduct experiment,observe,form a conclusion,communicate.

    • Eat a pie, observe the leftovers draw the leftovers.

    • Think

    Correct Answer
    A. Ask questions,collect info,form hypothesis,plan an experiment,conduct experiment,observe,form a conclusion,communicate.
    Explanation
    The correct answer is a sequence of steps that outline the scientific method. It begins with asking questions to identify a problem or topic of interest, followed by collecting information or data related to the topic. Then, a hypothesis is formed, which is a proposed explanation or prediction based on the collected information. Next, a plan is made to conduct an experiment to test the hypothesis. The experiment is carried out, and observations are made to gather data. Based on the observations, a conclusion is formed to determine if the hypothesis is supported or not. Finally, the results and findings are communicated to others.

    The process by which plants convert sunlight into energy is called __________.

    Correct Answer
    photosynthesis, Photosynthesis
    Explanation
    Photosynthesis is the process by which plants, algae, and some bacteria convert sunlight into chemical energy. Using sunlight, plants transform carbon dioxide and water into glucose (a form of sugar) and oxygen. This process takes place primarily in the chloroplasts of plant cells and is essential for providing energy to nearly all life on Earth, as it forms the basis of the food chain.

    Jake and Max are experimenting on what happens when they add a whole bag of Mentos in a 2 liter of both Coke and Pepsi combined. What can you predict will happen?

    • It will do nothing

    • It will burst into a giant explosion

    • It will puff out smoke

    • It will catch on fire

    • It will turn solid

    Correct Answer
    A. It will burst into a giant explosion
    Explanation
    When Mentos are added to Coke or Pepsi, a chemical reaction occurs. The rough surface of the Mentos candy provides nucleation sites for the carbon dioxide gas in the soda to rapidly escape, causing a rapid release of gas. This gas release creates a high amount of pressure inside the bottle, leading to an explosive eruption of soda. Therefore, when a whole bag of Mentos is added to a 2-liter bottle of Coke and Pepsi combined, it is likely to burst into a giant explosion.

    • 6

    • 100+

    • 5

    Correct Answer
    A. 6
    Explanation
    The correct answer is 6 because there are six simple machines: lever, pulley, wheel and axle, inclined plane, wedge, and screw. Each of these machines has a specific purpose and can be found in various everyday objects, such as a seesaw, crane, bicycle, ramp, knife, and screwdriver.

    Which of the following is an example of a chemical change?

    • Ice melting into water 

    • A piece of paper being torn in half 

    • Wood burning in a fireplace 

    • Salt dissolving in water

    Correct Answer
    A. Wood burning in a fireplace 
    Explanation
    A chemical change results in the formation of new substances with different properties. When wood burns, it reacts with oxygen to produce ash, carbon dioxide, water vapor, and other products. These products have different chemical compositions than the original wood. The other options represent physical changes, where the substance may change form but not its chemical identity.
