4th Grade Science Updates
We will begin the week reviewing decomposers, consumers, and producers. Then we will begin to look at the 4Rs (reduce, reuse, recycle, and rot). We will focus the rest of the week on rot, specifically on composting with worms, which will be the basis of our first interdisciplinary project. They will observe worms and set up a worm bin system in the class, devise how to collect green waste to feed the worms, and brainstorm questions they would like to investigate with the worm bin.

This week 4th graders will expand their understanding of an ecosystem by learning about food chains and food webs. They use organism cards to build food chains and food webs and discuss the role of producers, consumers and decomposers in those webs. We’ll finish off the week by discussing bacteria’s crucial role in food webs and what the world would look like without decomposers.
This week 4th graders will be writing about their isopod and beetle investigation about soil preference that they completed on Friday. Then, they’ll conduct another investigation to determine the light preferences of the isopods and beetles. Later in the week, learners will explore our classroom aquatic environment with goldfish and we’ll differentiate between living and nonliving things.
This week, we will introduce our first unit to the 4th graders. It’s a life science unit about different environments and the organisms that live their. Learners will take a pre-test on the material we will cover, share out what they already know and set up their science notebook for the coming unit. Later in the week, they’ll set up terrariums in table groups by planting seeds and deciding how much to water their terrariums. Learners will measure their plants and record growth over the next few weeks. They’ll also read an article about terrestrial environments and introduce sow bugs and darkling beetles into their terrariums. |
