The science club at Hanul High School is running a project called "Grow Light." It tests how different colors of light affect plant growth. Each week, members place ①identical bean sprouts under red, blue, and white light and record their height. At first, many students expected the white light to produce the tallest plants. However, the results showed that plants under red light grew ②noticeably faster than the others. The club's advisor explained this by comparing light to food. Just as people need certain nutrients to grow strong, plants absorb certain colors of light more ③efficiently than others. To make the data ④reliable, students repeat each trial three times and calculate the average. They also keep a shared notebook, recording sunlight, watering time, and temperature. Next month, the club plans to ⑤hide these findings at the school science fair.

When someone's heart suddenly stops beating, the brain begins to suffer damage within minutes unless blood keeps circulating. Studies show that a person who receives CPR immediately from someone nearby is far more likely to ①survive than one who waits for professional help to arrive. Despite this, many people ②hesitate to start chest compressions, worried that they might break a rib or make the situation worse. Modern CPR training has also been ③simplified, focusing on firm, rhythmic chest compressions rather than the more complicated combination of breaths and compressions once required, making the skill ④easier for ordinary students to learn and remember under pressure. For this reason, many schools now ⑤exclude CPR training as a standard part of health education.

The city government has launched a summer energy-saving campaign to ①reduce electricity use during the hottest months. Using fans together with air conditioners cools rooms more efficiently while using ②more power. To prevent blackouts, residents are asked to set air conditioners no lower than twenty-six degrees Celsius, which helps save ③energy. Businesses are asked to dim unnecessary outdoor signs after ten at night. Families who reduce their electricity use by more than ten percent will receive a ④discount on their next bill, which is a nice ⑤reward for their effort.

For our club's spring project, we were told to create a sculpture using only materials collected from the school's recycling bins, and my first reaction was ①disappointment at not being allowed to buy proper art supplies. Sorting through flattened cardboard, broken umbrella frames, and plastic bottle caps, I initially saw nothing but ②trash. My perspective shifted once a senior member showed me a piece she had built the previous year, a bird made entirely of bent bicycle spokes and bottle caps, each cap functioning as a single ③feather. She explained that upcycling art forces a creator to notice a material's natural shape and texture rather than simply painting over it, which often produces more ④original results than starting with a blank, expensive canvas. By the end of the project, our team had built a small forest of figures using nothing that anyone had paid for, and the exhibit visitors seemed ⑤indifferent to our materials, focusing only on our technique instead.

Science labs feel far ①safer than they actually are, largely because the equipment looks harmless and the experiments are carefully planned by a teacher. This false sense of security leads some students to skip small precautions, such as wearing safety goggles for a "simple" experiment or tasting a substance out of ②curiosity. Chemical reactions, however, do not distinguish between a professional laboratory and a classroom; a small amount of the wrong substance splashed into an eye can cause ③permanent damage within seconds, regardless of how basic the experiment seemed. Teachers repeatedly emphasize reading each instruction before touching any material, since even a familiar-looking chemical can behave ④unpredictably when combined with something new. Most laboratory accidents, researchers note, do not happen during advanced or unusual experiments but during routine ones that students have performed many times before, precisely because familiarity breeds ⑤caution rather than carelessness.

The Greenfield Public Library will offer a variety of special programs for students during summer vacation. From July 20th to August 14th, students can join reading clubs, writing workshops, and science experiment classes. ___________. Interested students should sign up at the front desk or through the library's website before space runs out.

I even brought a textbook along, planning to study quietly if the painting turned out to be boring. During exam season last year, our school counselor introduced a weekly drop-in session where students could paint freely for thirty minutes without any instructions or grading. ( ① ) I attended mostly out of curiosity, expecting a relaxing but ultimately pointless activity, since I have never considered myself artistically talented. ( ② ) To my surprise, filling a blank page with color, without worrying whether the result looked good, left me noticeably calmer than scrolling through my phone during the same amount of free time. ( ③ ) The counselor explained that art therapy does not aim to produce impressive paintings; it simply gives people a way to express feelings that are difficult to put into words, especially frustration or anxiety that builds up silently during a stressful week. ( ④ ) Several classmates who initially came only to avoid studying kept returning on their own afterward. ( ⑤ ) None of us left with a masterpiece, but many of us left the room feeling noticeably lighter than when we had walked in.

This makes it one of the most difficult winter hazards to prepare for in advance. When temperatures drop below freezing overnight, an invisible layer of black ice can form on sidewalks that look perfectly dry, catching even careful walkers off guard. ( ① ) Unlike a visibly icy patch, black ice reflects almost no light and blends into ordinary pavement, which is why so many falls happen on stretches that pedestrians would never suspect. ( ② ) Orthopedic doctors report a sharp rise in wrist and hip injuries every winter, most of them caused not by dramatic slips on icy hills but by a single unexpected step near a bus stop or a doorway. ( ③ ) Walking with shorter, flatter steps and keeping the hands free rather than in pockets can help a person regain balance quickly if a foot suddenly slides. ( ④ ) Choosing shoes with textured rubber soles rather than smooth ones also makes a difference, since even a small increase in grip can prevent a fall before it begins. ( ⑤ ) Treating every winter sidewalk as potentially icy, rather than trusting appearances, remains the simplest way to avoid injury.

Reservations made online receive a ten percent discount compared to walk-in rentals. Sunny Beach Rentals is now open for the summer season, offering a wide range of water equipment for visitors. ( ① ) Customers can rent items such as beach umbrellas, folding chairs, snorkeling gear, and paddleboards at affordable daily rates. ( ② ) To rent equipment, visitors simply need to show identification and pay a small deposit, which is fully refunded when the items are returned in good condition. ( ③ ) Equipment is checked carefully before and after each use to ensure everything remains clean and safe. ( ④ ) Renters are asked to return all items by six in the evening, since the shop closes shortly after sunset. ( ⑤ ) Damaged equipment must be reported immediately so that it can be replaced quickly.

Even a short glance downward, timed badly, is enough to miss an oncoming bicycle or a changing traffic light. Walking down a crowded street while staring at a phone screen has become such a common sight that it barely draws attention anymore, even though the habit turns a pedestrian into one of the least alert people on the sidewalk. ( ① ) Researchers who study attention describe this as a kind of tunnel vision: a person absorbed in a text message or a video processes only a narrow slice of the surrounding environment, filtering out approaching cars, uneven pavement, and other pedestrians almost entirely. ( ② ) Hospitals have reported a steady rise in injuries linked to distracted walking, ranging from minor scrapes after tripping over a curb to serious collisions with moving vehicles at intersections. ( ③ ) What makes this danger especially difficult to address is that pedestrians rarely recognize the risk in the moment. ( ④ ) Unlike distracted driving, which is widely condemned, glancing at a phone while crossing the street still feels like a harmless habit to most people who do it every day. ( ⑤ )
