We are sampling the Sheboygan River today for microplastics and collecting other water quality data.
Everyone please dress to be out in the weather the whole period.

Goal:
1) Review Density 2) Learn about the different water measurements we will be taking with our water samples. Do Now: Go to Google Classroom for Nov 1 and open your assignment: "Density Knowledge and Skills Expectations." Read through it and check off knowledge on the left and skills on the right that you feel confidence you know and understand. Open this Quizlet Set and spend 5 minutes reviewing the terms and definitions. We are going to play a game of Heads Up using these. Play Heads up: 1) There will be a stack of cards in the middle. In a group of 3-4, one player takes a card WITHOUT LOOKING AT IT. They place it on their forehead facing the other players. The card person now has 10 questions they can ask to figure out what word they have on their forehead. If they guess they get a point. Teams will mix and sit to pay another round. Water Quality measurements we will be taking when sampling for plastics. Why?
Ticket out: Be ready to go to the river tomorrow - quick plankton net test. Goal:
1) Establish a sampling protocol so we are ready to sample when our equipment arrives. 2) Understand the different water quality measurements we will make. Do Now: Check the Great Global Nurdle Hunt website and see if our data is up yet. Lesson 1: We will examine a scientific article about Microplastics as a professional example (mentor text) that we can emulate.
Pretend you have been hired to lead this project. You have a few field interns working for you. You need to write up a protocol they can follow for collecting microplastic samples. Go to this Google Form and follow the directions for starting to write up our materials and methods. We will share these out and eventually come to a class consensus on sampling methods we will all follow. Studio Time 2: While waiting for the rest of the class, please open your Density Summary Sheet assigned to you in Google Classroom. Read through it carefully. Check the boxes of skills or knowledge you feel very confident about. Leave anything you aren't sure about blank. This will help me know who needs to practice what skill. When you are done with that, please open the Quizlet and practice. using one of the Quizlet tools. If time - Play Quizlet Live - Density The Great Global Nurdle Hunt
We are walking to South Municipal Beach to hunt and count nurdles. We will then upload our information to the Great Global Nurdle Hunt Website. We found a total of 19 nurdles after an average of 10 minutes searching per person with 16 students searching. Do Now | Quick Jot Grab your notebook and write a response to the following prompt:
Let's get some of those responses up on the board. Demo: Objects in Water Watch closely as I drop some objects into the water.
Buoyancy Buoyancy is a force that acts upon objects in a fluid. Buoyancy can be positive, negative, or neutral.
Experiment
In your notebook, write your own definition for buoyancy. Turn in your notebook on the way out of the classroom. REMINDER: Walking Field Trip tomorrow to South Side Municipal Beach to participate in the Great Global Nurdle Hunt. Dress for the weather and walking. We will be working at the beach for about 30 minutes sifting through sand and looking for and counting nurdles. Goal: Come to Class consensus on our sampling sites with rational explained.
Do First: What are the steps to designing a survey study like this? What questions do we need to answer and in what order? Next: Students write reasoning for their sampling site choices on their sheets from yesterday (paper). Everyone share with the class. Discuss each one and tally how many people think it is a good idea. Narrow our sampling sites down to what we think is manageable and will give us interesting information. Project Planning: We will work in small groups and as a class to think through and create a more detailed sampling plan. What materials do we need? Where can we get them? How do we decide which materials and equipment are best for our sample collection efforts this year? Field Trip on Tuesday, Oct 26: Preview for joining the Great Nurdle Hunt. Field Trip on Tuesday to do a systematic hunt for nurdles on South Side Municipal Beach. Please come prepared for the weather. Gloves and sieves will be provided. Learning from this effort will include how to planning and conducting a scientific survey. What data should we and will we collect and why? We will also employ other methods of sample collecting in our search for microplastics. Ticket out: Tell me what we are doing next Tuesday and what you will do to be prepared. Goal: Choose sites for sampling both sediment and water for microplastics.
Do Now: Grab a map handout and an article and underline or highlight any information that would be useful for us when we design a sampling strategy for Sheboygan. Circle and look up any words you don’t know. Do Next: What are things that could affect how many plastic pieces we get in each sample on any given day and sampling spot? Individually jot down some of your ideas on this sheet. Class share. On your map, choose 4-8 sites you think we should sample around the Sheboygan area. We will explain reasoning for your choices tomorrow. Learning Goal: Finish constructing and test out our plankton sampling devices at the boat launch near Visit Sheboygan.
Do Now: Finish constructing your devices. Action: We are walking to the boat launch area to use our plankton nets. Students should be thinking about how their designs work well and what design flaws they see. What is easy and difficult about this sampling site. What do we need to consider in the future about sampling devices and sampling sites? Ticket out: Wash hands and clean up any mess around your area. Learning Goal: Design a fair test experiment to test sampling methods for microplastics in the Sheboygan River. Do Now: Please get out your science notebooks. Lesson 1 - Density revisited 1) Return Density Gizmo Work and discuss. We will practice with density this week and have a quiz on it on Thursday or Friday. 2) Sign into my class on EdPuzzle and we will do a quick EdPuzzle Live together on Density. I will project the class code in class. Lesson 2 - Building plankton nets and designing ways to test them. What are plankton? 1) Let's look at someone's design for a plankton net that we can build in the classroom. 2) What kinds of investigations can we run to determine a good sampling method with our DIY plankton samplers? - What variables will affect how many plastics we find? - Which of these variables can we control and which can we test? When we have our ideas for our investigations, we can build our sampling devices and be ready to test them on the river this week. Confused about Metric Conversions? Use this video to practice using the ladder method. |
Course DescriptionStudents will be creating a standardized method of collecting microplastics in conjunction with community science members. A mobile application will be created to quantify the amount of microplastics throughout the Great Lakes.
