https://padlet.com/dwang34/9z8egoix52gj6y7m How do whales, polar bears, and even penguins keep warm? The ocean is a cold place, but many mammals call it home! So how do our favorite mammals survive in such cold conditions? That is because they have something called blubber on them. Although neither you nor I need much water to survive, we don't need to live near the ocean. But creatures like polar bears, whales, seals, and penguins do! Today, you will be in your kitchen, using an experiment to test how blubber acts as an insulator to keep your body warm. en-us 2021-05-21 01:11:10 UTC 2025-10-07 07:05:06 UTC hello@padlet.com https://padlet.net/icons/png/1f427.png dwang34 https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546156547 鲸鱼、北极熊甚至企鹅是如何保暖的呢?
海洋是一个寒冷的地方，但有许多哺乳动物把它称为家园!我们喜爱的哺乳动物是如何在如此寒冷的环境中生存的呢?这是因为他们身上有一种叫鲸脂（blubber）的东西。虽然你和我都不需要太多的水来生存，因此我们不需要住在海洋附近。但是像北极熊、鲸鱼、海豹和企鹅这样的生物绝对需要!
今天，你将在厨房里，用实验来测试鲸脂是如何充当绝缘体来保持体温的，这是简单的海洋科学!]]> 2021-05-21 01:16:47 UTC https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546156547 dwang34 https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546159111 2021-05-21 01:17:43 UTC https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546159111 dwang34 https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546160508 2021-05-21 01:18:12 UTC https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546160508 dwang34 https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546161598 2021-05-21 01:18:35 UTC https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546161598 dwang34 https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546165936 2021-05-21 01:20:03 UTC https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546165936 dwang34 https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546165963 2021-05-21 01:20:04 UTC https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546165963 dwang34 https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546165992 2021-05-21 01:20:04 UTC https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546165992 dwang34 https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546165996 2021-05-21 01:20:04 UTC https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546165996 dwang34 https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546166099 2021-05-21 01:20:07 UTC https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546166099 dwang34 https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546166133 2021-05-21 01:20:07 UTC https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546166133 dwang34 https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546166824 2021-05-21 01:20:22 UTC https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546166824 dwang34 https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546166893 2021-05-21 01:20:24 UTC https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546166893 dwang34 https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546166907 2021-05-21 01:20:24 UTC https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546166907 dwang34 https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546167334 2021-05-21 01:20:29 UTC https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546167334 dwang34 https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546167379 2021-05-21 01:20:30 UTC https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546167379 dwang34 https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546167430 2021-05-21 01:20:31 UTC https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546167430 dwang34 https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546167432 2021-05-21 01:20:31 UTC https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546167432 dwang34 https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546167435 2021-05-21 01:20:31 UTC https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546167435 dwang34 https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546167459 2021-05-21 01:20:31 UTC https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546167459 dwang34 https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546167473 2021-05-21 01:20:32 UTC https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546167473 dwang34 https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546167477 2021-05-21 01:20:32 UTC https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546167477 dwang34 https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546167485 2021-05-21 01:20:32 UTC https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546167485 dwang34 https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546167486 2021-05-21 01:20:32 UTC https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546167486 dwang34 https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546167524 2021-05-21 01:20:33 UTC https://padlet.com/dwang34/9z8egoix52gj6y7m/wish/1546167524
