question:I recently wrapped up a fantastic unit on environmental science with my K-5 class, and I couldn't be more excited to share the experience! We explored topics like ecosystems, conservation, and renewable energy through a mix of hands-on activities and a new educational app, [GreenWorld Explorer]. The app allowed us to dive into virtual environments and conduct simulated experiments, which really captured the students' interest and curiosity. One of the most memorable moments was when we planted a small garden in our schoolyard. The kids were so engaged, and it was amazing to see them make connections between what they learned in the app and the real-world application of their knowledge. Their insights and enthusiasm were truly inspiring! I attended a professional development workshop on integrating technology in the classroom a few weeks ago, and it really opened my eyes to new possibilities. I’m grateful for the tools and resources that are out there to make learning more interactive and meaningful. Have you tried any innovative methods or apps in your environmental science lessons? I'd love to hear about your experiences and any resources you recommend! Let's keep the conversation going and support each other in our educational journeys. 🌱👩🏫 #EcoEducation #K5Learning #TechInClassroom #EnvironmentalScience #TeachingTips

question:By . Leesa Smith . Complete chaos descended on Sydney Airport after the domestic terminal shut down for more than three hours today due to a power outage, causing long delays and cancellations of flights for thousands of disgruntled passengers. Power has now been fully restored at the T2 terminal and security screening has recommenced while airlines are back operating check-in counters and facilities. Jetstar advises passengers on flights that weren't cancelled, to head to the airport as scheduled, but delays were still expected. 'We are working to move passengers through the terminal as quickly as possible,' a Sydney Airport spokesperson said. Scroll down for video . Chaotic scenes at Sydney airport as a power outage shuts down the domestic terminal . Power is being 'progressively' restored at Sydney airport . Travel chaos: A power outage left thousands stranded at Sydney's T2 domestic terminal . A passenger commenting on the terrible timing of school holidays beginning today in NSW . A mother comforting her young baby as she sits on the airport floor while waiting to get on a flight . A Virgin plane grounded on the tarmac at T2 domestic terminal due to the power outrage . The severe delays come just as the school holidays kick in, with the power outage meaning passengers could not check in and security screening could not be carried. It is also believed some passengers were stuck inside planes due to the power cut. The scale of the disaster is evident by the fact that free water was being handed out to the stranded thousands, while the rest of the airports across the country were expected to inevitably suffer from the flow-on effect of the delays. The power outage happened at 8.30am this morning and staff were told at 9.30am it would be back on by 11.30 this morning. However, the airport then ordered the shutdown of lifts and elevators in an attempt to get the power up. The airport said the outage was caused by an issue with a substation that provides back up power to the airport. Although the power is back on, passengers have a long wait ahead with further delays expected while the backlog is cleared . The scale of the disaster is evident by the fact that free water is behind handed out to the stranded thousands . With continuing delays expected passengers will need to keep hydrated as they wait to board their flights . Passenger, Helen Hayes, decided to attempt to make her way back home from the airport. 'Giving up and going home. It's just as mad outside the terminal as in!' she tweeted. Tigerair cancelled six flights due to the extreme delays and 10 Jetstar flights were cancelled .

answer:A power outage at Sydney Airport's T2 domestic terminal caused significant disruptions, shutting down the terminal for over three hours and affecting thousands of passengers. The outage, which began at 8:30 AM, led to long delays, cancellations, and stranded passengers, including the South Sydney Rabbitohs rugby team, who were en route to Townsville for an NRL match. Power was restored by late morning, but the chaos continued as airlines worked to clear the backlog. Jetstar and Tigerair canceled multiple flights, and passengers were advised to expect further delays. Free water was distributed to those stranded, and the airport and airlines are working to move passengers through the terminal as quickly as possible. The timing of the outage, coinciding with the start of school holidays in New South Wales, exacerbated the situation.
question:There are 2002 cards on the table with numbers 1, 2, 3, ldots, 2002. Two players take one card each in turn. After all cards have been taken, the winner is the player whose final digit of the sum of the numbers on their cards is greater. Which player can always win, no matter how the opponent plays, and how should they play?
answer:1. **Understanding the Importance of Last Digits**: The game objective depends solely on the last digits of the taken cards' numbers. Therefore, considering only the last digits for analysis simplifies the problem. 2. **Counting Distribution of Last Digits**: - Each of the last digits 0, 1, 2,ldots, 9 appear exactly leftlfloor frac{2002}{10} rightrfloor = 200 times in numbers 1, 2, 3, ldots, 2002. However, since 2002 mod 10 = 2, the last digit 1 and 2 appear 201 times each. 3. **First Player's Strategy**: - The first player should start by taking a card with the last digit 2 (201 cards available with 2 as the last digit). - After this, the first player mirrors the second player's moves, taking cards with the same last digit as the second player until the second player is forced to take the last card with digit 1 (since there are 201 cards with digit 1). 4. **Analysis After the First Phase**: - As the first player keeps countering the second player's moves, eventually the card pool will be such that both players will take cards with each digit evenly, except the digits 1 and 2. - The first player ends up with 200 cards of each last digit 0, 3, 4, 5, 6, 7, 8, 9, and 201 cards of the last digit 2. - The second player will have 200 cards of each digit 0, 3, 4, 5, 6, 7, 8, 9, and 201 cards of the last digit 1. 5. **Sum of Last Digits Calculation**: - The sum of the digits from 0 to 9 is 0 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 = 45. - Since the digits are evenly distributed between the two players, both will have sums involving each of these ten digits multiplied by 200, except for the digit 1 in the second player and digit 2 in the first player, appearing 201 times instead. 6. **Final Sums of Both Players**: Let's denote S_1 and S_2 as the sums of the last digits for the first and second players, respectively. Then: - For the first player: S_1 = 200(0 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9) + 2 - 2 cdot 200 + 2 - 0 = 0 times 200 + 1 times 200 + 2 times 200 + 3 times 200 + 4 times 200 + 5 times 200 + 6 times 200 + 7 times 200 + 8 times 200 + 9 times 200 + 2= 0. - For the second player: S_2 = 200(0 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9) + 2 - 1 cdot 200 + 1 - 0 = 0 times 200 + 1 times 200 + 2 times 200 + 3 times 200 + 4 times 200 + 5 times 200 + 6 times 200 + 7 times 200 + 8 times 200 + 9 times 200 + 1= 0. Both sum zero. 7: Conclusion: The first player will always win by making one card more by the digit 2 Thus the first player always wins the game regardless of the second player's strategy.
