Here’s a quick update about what’s happening in Science Class:
(1). We started our ecosystems unit: This unit is one of the easiest units for kids because they have studied ecosystems in other grade levels already. We review familiar concepts like food chains and energy pyramids. We also look at common cycles in nature — the water cycle, the carbon cycle and the nitrogen cycle. Finally, we study the parts of flowering plants that help them to survive, thrive and reproduce and we look at photosynthesis and cellular respiration.
(2). Your kids should be able to answer two questions today: If you ask your students, they should be able to tell you two things today: Why do human beings breathe in oxygen and why do plants breathe in carbon dioxide. Both of those questions are connected to photosynthesis and cellular respiration — and while kids often have general answers like, "We need oxygen to live," your kids should have specific details about how we use oxygen to help us survive.
(3). Lab due tomorrow / paragraph due on Friday: Your students have two tasks due for me this week. The first is a plant dissection lab. That’s due tomorrow. The second is a paragraph answering this question: Are plants nature’s most ingenious creation? That is due on Thursday. There’s been plenty of class time to tackle those tasks — so your kids might say they completed the work at school. If they are hard workers, that’s totally possible.
Hope this helps,
