Eggs-perimenting with eggs
What can you do with eggs other than eat them?
Naked Eggs
What does an egg look like without its shell? You may be picturing the white and yolk in a bowl after cracking it, but that isn't the only way to remove the shell.
Materials: an egg, white vinegar, a bowl, a spoon
Directions: Fill a bowl with one cup of vinegar. Add the egg to the bowl, and wait at least 24 hours. When you check it after a day, you'll notice some bubbles on the egg and a residue(残留物) in the water Use the spoon to gently remove the egg from the bowl. Dump out the old vinegar, and add a cup of fresh vinegar. Return the egg to the bowl, and wait another 24 hours. When you remove the egg this time, the shell should be completely dissolved. What remains will be the contents of the egg.
Walking on Eggshells
Can eggs hold the weight of your entire body?
Materials: six cartons(硬纸盒) of eggs, a garbage bag
Directions: Place the garbage bag on the floor to make any necessary clean up easier. Place the cartons of apps into two rows of three. Make sure all the eggs are pointing in the same direction either all pointy end up or all rounded end up. Step onto the first carton of eggs carefully. Make sure your foot is as flat as possible and that you are distributing your weight evenly. If you're careful, you will succeed. Eggs are actually incredibly strong. The arch shape at the top and the bottom of the egg allows pressure to be distributed evenly over the egg. If you were to place the eggs on their sides instead, you'd be likely to wind up with a gooey (胶粘的) mess.
Growing up on a farm, I learned from my parents about the large bees we called mangangava. But in college when I gave a presentation about those bees, I didn't mention their familiar name; instead I used formal terms when describing their adaptations for pollinating(授粉). I was afraid of being judged for expressing my personal knowledge in a science class. But when the instructor pressed me to tell the class whether I'd seen the bees myself and what I called them, my views and my whole career path began to change. I realized my background was valuable, and that my calling was to help educate others like me.
My parents work ed on a small farm and I often helped out when I was not in school. They had a close relationship with nature, something they learned from my grandparents and passed down to me. This was why I became interested in biology.
In college, I joined a series of labs to gain research experience, but my interest in pursuing a career as a scientist began to wane after I realized my research was not helping poor people like my parents As a black student from a rural community, I also felt out of place in most classes. The feeling of not belonging circled in my head. I sometimes thought about giving up.
My instructor's request that I share my knowledge of the mangangava bee changed my view. She saw that tapping into my personal experiences would help me grasp the scientific concepts. No other professor bad shown that kind of sensitivity, which helped me realize I did have a place in higher education and that I didn't need to hide who I truly am.
I'm now a master's student in education, working on a project that explores the connect ion between science and traditional knowledge. I don't think I'd be here if I hadn't crossed paths with my instructor. We ne ed more educators and scientists like her people who can serve as role models and know that the best way to nurture new scientists is to allow students to be themselves.
Most of us spend our lives surrounded by screens, which offer us convenience as well as connection and an ocean of information. But since it's easy to feel pressured to keep up with every notification, technology may feel more like a burden than a blessing. Thus, the idea of "digital detox" is becoming increasingly inviting.
The phrase "digital detox" describes getting rid of TV, phones, computers and other forms of technology that control our lives for a period of time. Some experts advocate completely avoiding unnecessary screen time for 30 years. Others suggest using an app that will limit the amount of time one can spend on certain websites. A third option is logging out in evenings or on weekends. Others simply turn their phones off at scheduled times. Some even pay high prices to take vacations in places where they can unplug from their digital routine.
Why might you want to take a digital detox? Perhaps you find that you are spending longer than you intend on certain apps or that they distract you from more important things. Perhaps social media is depressing because you compare yourself to others or you fear missing out on things that other people are enjoying. Constant negative news can also give rise to a lot of stress.
Technology can also have physical effects. Many people experience back or neck pain as a result of bending over screens. The blue light coming from most screens can also affect people's sleep by preventing production of melatonin(褪黑素).
Giving up all screens may not be realistic, but strategic breaks from technology may be good for your body, mind, emotions and relationships. It is high time that you picked a time to turn off your devices and focus on really important things.
Many of the psychological benefits of outdoor play are already well established. Our brains evolved in natural landscapes, and our perceptual(感知的) systems are particularly well suited to wild outdoor spaces.
This means that natural scenes provide the perfect level of stimulation, which is thought to help recharge the brain when it is tired and easily distractible. Supporting this theory, one study found that children with attention-deficit hyperactivity disorder(ADHD) were better able to concentrate following a 20-minute walk in the park, compared to a 20-minute walk on the streets of a well-kept urban area. Being exposed to grass and trees seemed to have had a beneficial effect on their minds. The authors recommended using such "doses(剂量) of nature" as a safe and accessible way of supporting children with ADHD, alongside other tools.
Besides these restorative effects, outdoor play can offer valuable learning experiences. For example, playing with mud or sand can help children develop the way their senses and movement interact, which allows the child to gradually understand his or her body signals.
Such activities away from the house or classroom may also help children to find ways to cope with emotions that may be hard to explore in other environments. So-called "sand tray therapy" which involves using sand and clay to express one's thoughts and feelings, is an accepted form of counselling for children who are struggling to verbalize their emotional state.
When it comes to the child's physical health, the most obvious advantage of outdoor play may be the exercise. A child may find it easier to build up strength and endurance in a large open space resulting in a reduced risk of overweight, according to one study led by Elizabeth Gershoff, professor of human development and family sciences at the University of Texas at Austin, US.
The latest findings, however, suggest there could be a host of other advantages to playing in natural environments ——and the secret may be alive in the mud itself.
