"My name is Jolene Johnson, but you can call me Jo-Jo. I have two new puppies, and you are all invited to see them after school!" Jolene said to the class when it was her turn to 1 herself.
Mrs. Anderson, the teacher, smiled and then introduced another new kid named Dee Rogen. When he spoke, he was quiet and didn't say much. To help Dee fit in, Mrs. Anderson then 2 him with Ben as his "friend" for the day.
At lunch time, Jo-Jo saw that Dee was sitting with Ben and his friends but not talking to anyone. He looked 3 , thought Jo-Jo.
Jo-Jo didn't like anyone to feel alone. She noticed that Dee had a shirt on that said "I Paused My Game to be Here. " Jo-Jo had an idea. She took her lunch near Dee and said, "I like your shirt. What games do you play?"
Dee smiled and said his favorite was Minecraft. Jo-Jo loved that 4 ! They spent the lunch break talking about the best ways to survive （存活）in the game.
On Friday, Jo-Jo said that she was having Minecraft.
Monday at her house after school and everyone in her class was invited. Jo-Jo pulled out a sign-up sheet from her schoolbag. Several students ran up to her at once.
Before school was over, Jo-Jo5 Dee hadn't signed up and asked him about it. "I don't really know anyone, Jo-Jo. " Dee answered. "I wouldn't feel 6 being there. "
Jo-Jo was confused because she thought he would love the idea. It was on her mind all day until she went home from school—where she had another 7 !
The next morning, she said to Dee, "I was thinking that organizing Minecraft. Monday would be a big job. How about you and I be partners? "
Dee started to 8 . "Wow, you really want me to be part of Minecraft Monday! "
"We would be a great team! "
"I think so too, " said Dee excitedly.

Math Week
'"Next week is Math Week. I would like each one of you to do a project. It will be shown at the Math Week exhibition. You could do it on your own or in a group, " Mrs. Lee, the math teacher said.
After school, Manu sat in the classroom along with Kevin who was not as good as Manu at math.
Kevin said, "Manu, shall we work on the math project together?"
Manu said, "Sorry, but I prefer to do it on my own. "
The next day, all the students submitted （提交）their topics for the math exhibition. Almost all of them worked in a group except Manu. Kevin's team decided to do Snakes and Ladders, Junaid's team decided to do a crossword puzzle, and Manu decided to do a magic game, and of course, he did it all alone.
Manu completed the project and was happy with the result. The night before the exhibition, he again checked the project to see if it was working fine. Alas! All the lights that were supposed to shine did not seem to light up at all. Manu was worried and even cried out because he didn't know how to fix it. In the end, he had no choice but to take it to school.
At the same time, Kevin's team were working on their project at Kevin's house. If one member got stuck somewhere, the others helped out. It was a sight of real team work.
Finally, it was time for the Math Week exhibition. All the teams placed their projects on the table with pride except Manu. Students enjoyed Snakes and Ladders. Manu was embarrassed （尴尬的）to present his non-working magic game. Mrs. Lee looked at him and said, "There's still time. Maybe you can get someone to help you with it. "
Kevin offered to help. Luckily, he fixed it just in time for the show.
Manu's eyes were shining with excitement and he said to himself "It's certainly great to have a teammate. "
Water lovers will tell you that not all water tastes the same. However, if your water tastes different when it's in a reusable plastic bottle, a new study finds it may be a cause for worry.
Two scientists, Jan Christensen and Selina Tisler, have undertaken a study about which chemicals （化学物质）in reusable plastic bottles go into the water. They let water sit for 24 hours in new bottles, in used bottles and in bottles that had just come out of a dishwashing machine. After that, they compared what they found in the water in the different bottles.
The results were quite a surprise. More than 400 difierent chemicals had leached （析出） from new plastic bottles into the water. Water stored in used plastic bottles had the highest levels of plastic-related chemicals. Running the bottles through a dishwasher worsened the leaching. After a single washing, more than 3,.500 difierent chemicals ended up in a bottle's water. Many of these were related to dishwasher soap （洗碗皂） and remained even after a second washing with running water. What's more, dishwashing itself also caused more plastic chemicals to leach.
Similar discoveries were also made by Pat Hunt, a biologist at Washington State University. She found that heat can cause chemicals to move out of plastics. Hot water in a dishwasher helps to clean dishes. But plastics can start to break down if they are in hot water repeatedly, "Plastics just shouldn't go in the dishwasher, " she concludes.
Christensen and Tisler5s study found some chemicals that are probably harmful. Future studies could make clear how much of each chemical is there. And that's important. Just because a chemical is in the water doesn't mean it will cause problems. Much of the risk will depend on how much of a chemical actually gets into the body.
Hunt agrees. "This study is a starting point, " she says. It gives researchers ideas about what chemicals from reusable bottles are probably in water. But it doesn't tell us what risks the now-polluted water may bring to us. More research is needed.
Still, lowering exposures （接触）to plastic-related chemicals is probably a good idea. Hunt suggests using non-plastic bottles. "If you do use a plastic bottle, fill it up and use it right away, " Tisler adds. "It's best not to store water in them overnight or for long periods of time. "
Why do we do the things we do? What drives our behavior? Psychologists have suggested different ways of thinking about motivation （动机）, including looking at whether motivation arises from outside （extrinsic） or inside （intrinsic） a person.
Researchers have found that each type has a different effect on a person's behavior and efforts to achieve goals. To better understand the influence of intrinsic and extrinsic motivation on human behavior, it would help to learn how each type works.
Extrinsic motivation is when you are motivated to perform a behavior or take part in an activity because you want to get a reward （奖赏）or avoid punishment. You will take action not because you enjoy it, but because you expect to get something in return or avoid something unpleasant.
Intrinsic motivation is when you decide to do something because you find it satisfying. You are performing an activity for what it is not because you are after some external （外部的）reward. The behavior itself is its own reward.
Studies have shown that offering too many external rewards for an already internally rewarding behavior can reduce intrinsic motivation—which is known as the over justification （奖励过当）effect. For example, in a 2008 study, children who were rewarded for playing with a toy they had already expressed interest in playing with became less interested in the toy after being externally rewarded.
This is not to suggest that extrinsic motivation is a bad thing—it can be beneficial in some situations. For example, extrinsic motivation can be especially helpful when a person needs to complete a task that they find unpleasant.
Most people would accept that intrinsic motivation is best, but it is not always possible in every situation. Sometimes a person simply has no internal wish to join in an activity.
Both extrinsic and intrinsic motivation play a key role in learning. Experts have argued that education's traditional stress on external rewards （such as grades, report cards, and gold stars） undermines any intrinsic motivation that students might already have. However, others have suggested that extrinsic motivators can help students feel more knowledgeable in the classroom, which in turn builds up their intrinsic motivation.
As professor David Myers put it, a person5s interest often survives when a reward is used neither to bribe （贿赂）nor to control but to show a job well done, as in a "most improved player" award. Put simply, rewards, rightly given, can increase enjoyment and motivate high performance.
Understanding how each type of motivation works and when it is likely to be useful can help people perform tasks and improve their learning.
Fighting Wildfires through Invention
At the age of 13, Prisha Shroff saw something that made her want to change the world. She was in the car with her family on the way home, when a big wildfire came in sight and forced them to turn back.
"I saw it in person,.5, she says. "The air pollution was so bad that we were told not to step outside of our car, or outside of our house. "
At the same time, Prisha remembered seeing other wildfires on the news. She thought, "This isn't just a small problem, it's a worldwide problem." And she decided to look for a way to help.
The opportunity came when she attended her middle-school science fair. For her project, Prisha decided to design a system that could discover and put out wildfires. Using A. L and satellite imagery （卫星影像）, it could know where wildfires would take place and also discover active fires.
In 2021, Prisha won the Lemelson Award for Invention, whose goal is to encourage young future scientists, engineers, and inventors to solve some of the world's biggest challenges. "That was the first big prize that I'd gotten, she says. "It really gave me confidence to find ways to solve big problems, and that I have the ability to make a big difference. "
Now 16, Prisha is working hard on her design to help fire stations. It is a drone sent to an active fire to spread retardant （阻燃剂）. " If they discover a wildfire, the drone can fly there, put it out, and come back。"Prisha says.
Prisha is crazy about creating solutions to not only mitigate （缓解）wildfires, but also the effects of climate change in general. "This is our planet, we should take care of it, " she says. Prisha now runs a special program at her school, and has spoken at the United Nations about the importance of learning certain knowledge and coming up with more inventions to help fight against climate change.
To future young inventors, Prisha says the key is to not simply hope something happens, but to actually try hard to make it happen, "You don't need to change the whole world, but you can still change someone's whole world, " she says.
