John was tuning his musical instruments with two tuning forks, fork A and fork B. He produced higher frequency with fork A and lower frequency with fork B. Interestingly, both frequencies had the same amplitude. Which fork would have lower frequency of the vibrations, fork A or fork B? Hint: The frequency of a wave is the same as the frequency of the vibrations that caused the wave. For example, to generate a higher-frequency wave in a rope, you must move the rope up and down more quickly. This takes more energy, so a higher-frequency wave has more energy than a lower-frequency wave with the same amplitude. You can see examples of different frequencies in the Figure below (Amplitude is the distance that particles of the medium move when the energy of a wave passes through them.)
Ans: fork B

Two islands were located in the Pacific Ocean. Woo island was frequently shaken by earthquakes, but Mud island had no such problems. Which island experienced more rocks breaking because of stress? Hint: Almost all earthquakes occur at plate boundaries. All types of plate boundaries have earthquakes. Convection within the Earth causes the plates to move. As the plates move, stresses build. When the stresses build too much, the rocks break. The break releases the energy that was stored in the rocks. The sudden release of energy creates an earthquake. During an earthquake the rocks usually move several centimeters or rarely as much as a few meters. Elastic rebound theory describes how earthquakes occur ( Figure below ).
Ans: Woo

Tom and Jerry were two 50-year-olds which went to high-school together. They recently met and discussed their health problems over coffee. Tom had hypertension and the doc told him to change his diet. Which friend had to start drinking skim milk? Hint: Hypertension , which is also called "high blood pressure," occurs when a person's blood pressure is always high. Hypertension is said to be present when a person's systolic blood pressure is always 140 or higher, and/or if the person's diastolic blood pressure is always 90 or higher. Having hypertension increases a person's chance for developing heart disease, having a stroke, or suffering from other serious cardiovascular diseases. Hypertension often does not have any symptoms, so a person may not know that he or she has high blood pressure. For this reason, hypertension is often called the "silent killer." Treatments for hypertension include diet changes, exercise, and medication. Foods thought to lower blood pressure include skim milk, spinach, beans, bananas and dark chocolate.

Two college groups did a one year experiment on each other. One group called Group Alpha spend more time and worked together. Group Beta let it's members study on their own and be less dependent on the group. Group Alpha had better results. Which group experienced more suggestions for future works? Hint: When peer feedback is established it allows students to interact with their peers and creates high social skills while learning material more effectively. Interaction with other students allows students to have better social approaches when interacting. Learning by peer feedback gives students more of an opportunity to work as a unit instead of individuals working alone. Working in groups gives students more useful life skill that well help prepare them for the future. Peer feedback gives more control to the student, the student can decide if they want to use the criticism their peers are giving them or not. When given options more students are more likely to give and absorb more feedback. Peer feedback has confirmed an increase in affect; students that have increasing responsibilities have more drive towards their work and a spike in confidence.[6] Furthermore, Kristanto (2018) found that peer feedback is an essential element of peer assessment. In peer assessment, feedback from peers can provide suggestions or correction for students' future works as companion of the received grade.[7]
