4th Grade Science Updates
4th graders this week will be discussing the hierarchy of the four Rs (reduce, reuse, recycle, rot/ compost) in order to prepare for their field trip next week to Davis Street Transfer Station. Learners will be watching a video that shows the 4Rs in action and finding out more about how they can practice the 4Rs. We will do some review and have our 1st benchmark on Wednesday.

4th graders will be monitoring their brine shrimp experiments to find out which salinity level hatched the most brine shrimp. They will study the Mono Lake environment to find out where brine shrimp fit into the food web there and what other organisms live there.
This week the 4th graders will be participating in the population simulation of deer that we did not get to on Friday. Then we will study some ways that animals can communicate with each other. Learners will experience what it is like use their sense of hearing without having sight. We will read about some other ways animals communicate. Then we will experiment with brine shrimp, looking at the range of tolerance they have for salinity in their environment.
This week 5th graders will take a look at the watershed we live in, mapping out key features of it. We will also be studying the difference between the sewer and storm drain systems. Then we will watch a mockumentary about a peice of trash travelling through a watershed and seeing how much of our garbage ends up in the Great Pacific Garbage Patch in the Pacific Ocean. We will create comic strips based on the video. Over the weekend, learners will have a water log to complete over a 24 hour period to track their water usage.
4th graders this week will review terrestrial environmental factors and then we will observe our class aquariums to identify their environmental factors. We will classify them as living and non-living. Then we will look at terrestrial and aquatic food chains and food webs using organism cards from a woodland environment. We will make a visual vocabulary flipchart to practice the new vocabulary associated with food webs. At the end of the week we will do a population simulation to learn about resource scarcity and the carrying capacity of an environment.
