Like many parents working from home while their kids are learning remotely, we’ve been looking for creative ways to connect with our children — and nowhere has this been truer than in the kitchen.
Kitchen science, as Liz Heinecke, author of Kitchen Science Lab for Kids calls it doesn’t require any fancy equipment or ingredients (配料)—and, best of all in the era of remote education, we can combine science lessons with everyday meal preparations. By helping with cooking, kids can engage in lively, project-based lessons. Actually, even the easiest recipes include both simple and complex scientific concepts.
Kitchen science isn’t just about what we’re cooking: it’s also about understanding why It’s worth taking the time to figure out how ingredients and temperature interact and why substances behave the way they do. Everyone involved will learn something.
For example, we all know oil and water don’t mix easily, but we can change this by adding mustard (芥末) to the oil and water to make a salad dressing. This is an opportunity to teach kids about the science of emulsions (乳化). Adding lemon juice to a vegetable stops that vegetable from turning brown: cabbage changes color when you add vinegar to it. Both of those phenomena are the result of chemical reactions. In the classroom, it can be hard to see how scientific concepts will apply outside the lab. But when kids see these concepts play out in the real world, that sparks curiosity and learning.
“Every time you step into your kitchen to cook, you put science to work. In fact, physics and chemistry come into play whenever you steam, bake, freeze or boil. Thus, every time you step into the kitchen, it’s an opportunity for everyone to learn more about science,” Liz Heinecke said.

【推荐1】When children are growing up, what they see in their families is what they tend to consider normal. That means family traditions and other activities are generally seen as just normal. If a family eats dinner together or spends time talking with each other, that’s what the child absorbs and internalizes.
Our family traditions are declining as we move toward a more isolated (孤立的) society. How many families no longer share meals around the dinner table, instead choosing to watch TV or text friends on their phones? This tends to isolate and disconnect family members from each other. It also stops families from communicating and catching up on each other’s lives.
For those of us who grew up in a household where families shared meals together and spent time talking with each other, chances are that we are passing along those traditions to our own families. The problem is, children today often want to spend their time in front of screens rather than people. Cell phones, computers and other attention-grabbing devices often mean parents get resistance to traditional family togetherness time. This pressure can lead to parents giving in and letting children do what they want rather than fight with them over sitting at the dinner table. This creates a new normal that no longer values the idea of families and the society at large, connecting with each other.
Family and community traditions are important, not just for the current shared experiences, but for the future as well. Since children internalize their experiences, that means generations to come may not know what it’s like to sit together around the dinner table and truly connect as a family.
That is why it is so important that parents and caregivers create boundaries of behavior that help to keep family traditions alive. If you remember the shared experiences you had with your parents and grandparents, you know the important bonding that took place during those times. It is this shared experience that brings people closer together and is well worth preserving.

After we all came to the conclusion that our family could responsibly care for a dog, my husband and I started our search at a local animal shelter.
We discovered a medium-sized male dog named Duke. This dog was approximately only two years old and seemed to have the sweetest character. He looked at us through intelligent eyes and already knew how to fetch a ball. My husband and I immediately adopted him Duke quickly fit into our family's lifestyle . And he quickly learned the tricks like “sit”,“stay”,and “come”.
But there was one skill that Duke could not seem to grasp — that of a watchdog. My husband was trying to teach him to remind us by giving a single warning bark when someone came into the yard. Duke would listen carefully to my husband's commands, but would cock (竖起) his head to one side in confusion and disappointment as if to tell his master that he just didn't understand what my husband was asking him to do. My husband would give his “watch” command. Duke would stand up -- muscles tightened in readiness, but would not have a clue as to what he was in readiness for.
One morning we heard the garbage collectors come up the driveway to get our garbage. My husband went to the open bedroom window so Duke could hear and see the men through the screen .
“Watch!” my husband commanded. Duke rose up in readiness, looked at my husband as sudden comprehension dawned on him, gave a quick tail wave, and leaped through the window screen, jumping happily out to greet the garbage men.
Seeing that, I couldn't help laughing. My laughter did nothing for my husband's mood when he found what was happening and he just went away to repair the screen with no expression on his face.
Duke brought our family so much fun. We never scolded or beat him. He was one of our family members.

My dad, George, only had an eighth grade education. A quiet man, he didn’t understand my world of school activities. From age 14, he worked. And his dad, Albert, took the money my dad earned and used it to pay family expenses(费用).
I didn’t really understand his world either: He was a livestock trucker (牲畜卡车司机), and I thought that I would surpass (超过) anything he had accomplished (完成) by the time I walked across the stage at high school graduation.
Summers in the mid-70s were spent at home shooting baskets, hitting a baseball, or throwing a football, preparing for my future as a quarterback (橄榄球的四分卫) on a football team. In poor weather, I read about sports or practiced my trombone (长号).
The summer before my eighth grade I was one of a group of boys that a neighboring farmer hired to work in his field. He explained our basic task, the tractor fired up and we were off, riding down the field looking for weeds (杂草) to spray with chemicals. After a short way, the farmer stopped and pointed at a weed which we missed. Then we began again. This happened over and over, but we soon learned to identify different grasses like cockleburs, lamb’s-quarters, foxtails, and the king of weeds, the pretty purple thistle (蓟草). It was tiring work, but I looked forward to the pay, even though I wasn’t sure how much it would amount to.
At home, my dad said, “A job’s a big step to growing up. I’m glad you will be contributing to the household(一家人).” My dad’s words made me realize that my earnings might not be mine to do with as I wished.
My labors (劳动) lasted about two weeks, and the farmer said there might be more work, but I wasn’t interested. I decided it was not fair (公平的) that I had to contribute my money.
Paragraph 1: The pay arrived at last.
Paragraph 2: I understood immediately what my parents were worried about.

The researchers at Kanazawa Medical University, Japan and American company Johnson conducted the study together. They looked at the effects of light reflection on newly fallen snow on a ski trail in Ishikawa District, northern Japan. They compared the results with the levels of UV rays on a sand beach in southern Japan's Okinawa District.
They found that on the beach, eyes are exposed to a daily 260 kilojoules (千焦耳) of UV a square meter compared to 658 kilojoules in snow-covered areas.
The findings are supported by the Japan Meteorological (气象的) Agency. According to the agency, the reflection rate of UV light on beaches is often between 10 and 25 percent, compared to 80 percent in the new snow areas. The amount of light increased 4 percent with a 300-meter rise in height.
Most of us know that UV rays can harm the skin. That's why we wear sunscreen on our skin before we get out in the sun. But many of us may not realize that UV rays are also harmful to the eyes.
If your eyes are exposed to large amounts of UV radiation over a short period of time, you may experience a kind of sunburn of the eye, which is harmful. Your eyes will become red and feel a strange feeling. They may be sensitive to light. Fortunately, this is usually temporary and seldom causes permanent damage to the eyes.
Long-term exposure to UV radiation, however, can be more serious. Scientific studies and researches have shown that exposure to small amounts of UV radiation over a period of many years increases the chance of eye damage, which could lead to total blindness.

【推荐3】If you ever find yourself yawning during a long Zoom video call, you may soon see yawns (打哈欠) spread to the other faces on your screen. Your pet under the desk may even join in.
Yawns can spread even between dogs and humans, as reported in 2008 and 2012. At the time, empathy — the ability to put yourself in another’s shoes — was one of most probable explanations. But new evidence suggests this reasoning is wrong.
To get a better understanding, researchers examined whether dogs’ yawning follows the same behavioral patterns with humans. For instance, people are both more likely to yawn with friends and families than with strangers. Besides, women, on average, report greater feelings of empathy (共情) than men, and catch yawns more frequently. But earlier this year, when researchers analyzed previous studies of yawning in dogs, they found no sign of these biases (偏向).
How often do dogs catch yawns from humans who are nice or not so nice to them? In another study, an experimenter would either play with or pet the dog, or plainly ignore the dog and avoid all eye contact. The anti-social experimenter would also show the dog a treat and command it to perform a trick, and then eat the treat themselves. But this did not affect the dogs’ yawning.
It’s still unclear why we yawn in the first place. One hypothesis is that yawning is a stress response that increases alertness by increasing blood flow to the brain and cooling it. “ Having yawns spread could help coordinate (协调) a group’s alertness. However, this is one nice evolutionary story that we don’t have that much evidence for. This isn’t to say your dog doesn’t have empathy at all. Instead, the study shows that animal minds are still a mystery. ” says Alex Taylor, an evolutionary psychologist.

【推荐2】In the thick forest, a New Caledonian crow carefully removes a branch, pulls off unwanted leaves and makes a tool from the wood. The crow is a perfectionist. When it’s satisfied, the bird advances the finished tool into a hole in the tree and fishes out a wriggling grub (蠕动的幼虫).
The New Caledonian crow is one of the only birds known to make tools, a skill once thought to be unique to humans. The remarkable originality that Christian Rutz, a behavioral ecologist at the University of St Andrews in Scotland, observed changed his understanding of what birds can do. He started wondering if there might be other ignored animal abilities. Experiments have shown that different crow groups in the forest have distinct vocalizations (发声). Rutz wanted to know whether these vocalizations could help explain cultural differences in tool-making among the groups.
New technology powered by artificial intelligence (AI) is ready to provide exactly these kinds of insights. Whether animals communicate with one another in terms we might be able to understand is a question of enduring question. “With recent breakthroughs in AI, people realize that we are on the edge of fairly major advances in regard to understanding animals’ communicative behavior,” Rutz says.
Beyond creating chat-bots that attract people and producing art that wins fine-arts competitions, machine learning may soon make it possible to crack (破解) things like crow calls, says Aza Raskin, one of the founders of the nonprofit Earth Species Project. Cracking animal vocalizations could aid conservation and welfare efforts. It could also have a shocking impact on us. Raskin compares the coming revolution to the invention of the telescope. “We looked out at the universe and discovered that Earth was not the center,” he says. The power of AI to reshape our understanding of animals, he thinks, will have a similar effect. “These tools are going to change the way that we see ourselves in relation to everything.”

Not everyone experiences anger in the same way; what angers one person may amuse another. The specific expression of anger also differs from person to person based on biological and cultural forces. In contemporary culture, physical expressions of anger are generally considered too socially harmful to be tolerated. We no longer regard duels (决斗) as an appropriate expression of anger resulting from one person’s awareness of insulting behaviour on the part of another.
Anger can be identified in the brain, where the electrical activity changes. Under most conditions EEG (脑电图) measures of electrical activity show balanced activity between the right and left prefrontal (额叶前部) areas. Behaviourally this corresponds to the general even-handed disposition (意向) that most of us possess most of the time. But when we are angry the EEG of the right and left prefrontal areas aren’t balanced and, as a result of this, we’re likely to react. And our behavioural response to anger is different from our response to other emotions, whether positive or negative.
Most positive emotions are associated with approach behaviour: we move closer to people we like. Most negative emotions, in contrast, are associated with avoidance behaviour: we move away from people and things that we dislike or that make us anxious. But anger is an exception to this pattern. The angrier we are, the more likely we are to move towards the object of our anger. This corresponds to what psychologists refer to as of offensive anger: the angry person moves closer in order to influence and control the person or situation causing his anger. This approach-and-confront behaviour is accompanied by a leftward prefrontal asymmetry (不对称) of EEG activity. Interestingly, this asymmetry lessens if the angry person can experience empathy (同感) towards the individual who is bringing forth the angry response. In defensive anger, in contrast, the EEG asymmetry is directed to the right and the angry person feels helpless in the face of the anger-inspiring situation.
