Resources for the AP® Environmental Science Exam

Read about the AP® Exam in these various posts. You can also find out the basics of the APES exam on this College Board website.

Labs For Each Unit in AP® Environmental Science

This is a list of labs with links that I do for each unit in the Course Exam and Description. There are many more great labs that APES teachers do. I chose these for the most “bang for the buck”–lots of concepts learned and/or science practices, feasible for many APES sections and large APES classes, feasible for my school’s outdoor area, and budget-friendly from year to year. I typically write small grants for equipment and then use over and over again.

For a list of lab supplies, read this post.

If I have a post written about the lab, you are able to click on the title of the lab to read about it.

Unit 1: The Living World: Ecosystems

Airborne Particulates Lab Using LED Tap Lights

I recently experimented using LED tap lights as an alternate to using stereoscopes in the Airborne Particulate Lab. You can read about the lab on this post. This is a great lab for kids to practice experimental design.

I purchased LED tap lights from Amazon but they can also be found at home improvement stores.

They work with a little finesse. Here is what the kids need to use:

Students need to focus on the vaseline above the grid. If they focus on the graph paper, they won’t see any particulates. They need to hold the hand lens about 3-4 centimeters above the petri dish. That way it focuses on the particulates.

This method does work, but it takes a little more practice from the kids to see the particulates.

Air Pollution Chalk Drawings

Acid rain chalk drawing

One way to help students memorize the 3 atmospheric processes they need to know for the AP® Exam is to have them draw. Research indicates that sketching or drawing information helps students learn. From my own experience, drawing with chalk helps my students memorize better than drawing on paper. Its a fun activity in groups and the kids truly learn. The 3 processes are:

  1. Tropospheric Ozone Formation (ground-level ozone in smog)
  2. Stratospheric Ozone Depletion (the ozone hole)
  3. Acid Deposition (Acid Rain)

Supplies for Chalk Drawing

I use chalk, because it is the most economical (and eco-friendly) choice. The best chalk is from IKEA–seriously. A few boxes will last the entire year or more. Since I teach 170 students in APES, this is the best option for me.

Neon Expo Markers are another good option. You can write a mini-grant or a request on Donors Choose to fund them.

You can write on lab tables if you have the standard science black finish. If not, you can draw with chalk outside.


Instructions for Chalk Drawing

My students follow the instructions on this document. I do not have them look up information and make their own drawing, because I do not want them looking up and copying diagrams on the internet. I want them to draw out the processes with the details and specifics that have been asked on released AP® Exams. They will learn when they use their brains to make pictures.

We do the 3 drawings on separate days so that students keep the details separate in their brains. Each processes takes about 20 minutes to do and my students work in groups of 4.

I check the drawings when they are fineshed and then they erase with water and paper towels. It is an activity that truly helps students learn the complicated processes needed for the AP exam.

Everything Ecocolumns

My students’ favorite lab is building and taking care of Ecocolumns.  This lab gives them practice in long-term data collection and a myriad of other essential topics in APES. Here are the posts you can click on to learn how to build, buy supplies and assess ecocolumns.

Biomagnification Activity from the Monterey Bay Aquarium

I really like this biomagnification activity from the Monterey Bay Aquarium. I discovered this activity in a Monterey Bay Aquarium workshop at a conference I attended a couple of years ago.  Its accessible for different levels of learners in regular NGSS Biology and regular Environmental science and has enough technical science for AP® kids.

The materials are easy to use and cheap. My school laminates for me to make the items durable for many years.

This activity focuses on POPs-Persistent Organic Pollutants and then plastic pollution in the ocean, but we discuss mercury pollution in top predatory fish as well.

How to do the Biomagnification Activity

The instructions from the Monterey Bay Aquarium are easy to follow,  but here are some pictures that may also help.

Each student gets a card. The instructions tell you the correct proportions for your class size. Each trophic level hunts at the same time.

These are ocean “molecule” cards.

I use the center lab table in my lab, but you can do this outside or inside on the floor. I spread them out and don’t worry about turning them all over. I tell students they can only “hunt” with one hand and place the molecules in the other hand.

A sample of molecules that were picked up and counted,

Students need to tally their POPs only. Then, they write their POP total on a mini post-it note.

The first round is all the phytoplankton–about (15-20 students). The second round is all the zooplankton (about 8-9 students), then the sardines (5-6 students), salmon (2-3 students) and finally 1 human. After the phytoplankton hunt, the other hunters during their round take the tally of POPs on the mini post-it-note from the previous trophic level and then continue to hunt on the table.

Sample data from a “Salmon”

After the simulation, students answer questions, read and annotate/highlight.

A nice leveled reading for students

I make copies of pages 8-10 of the document for my students. This is nice, easy and meaningful biomagnification activity for my students and leads well into Water Quality. 

Math Differentiation in Science

Students in science classes often have differing math abilities and its difficult to cover math without boring some kids and losing other kids. One way to approach  is to allow student to have choices on how to approach the math problems. This is a form of differentiation and allows kids to take ownership of their own learning. To do this method, you will need videos of your math lessons. This is not a onerous task. I usually record a worksheet in just 15 minutes on the Explain Everything app. I upload to Youtube, or Google Drive and share the links on Google Classroom.

Since videos are recorded, students can go at their own pace and direct their learning.

Introducing Differentiation to Students

Kids do well when they understand “why”. I go over the Immediate Goal with them:

  • To practice how to do various energy word problems in order to get a good grade on Exams, the Final Exam and the AP® Exam.

And the Ultimate Goal:

  • Life is made of word problems. You can use these skills as you analyze household bills, your car’s fuel efficiency, purchasing decisions, etc.  Some of you will also need these skills in your career.

Directions for Students

  • Skim your paper/s
  • Make a choice on how to proceed 

Choices:

A. Work through problems on own–persevering through difficult ones until your brain clicks and you have an “Aha” moment.  Check answers with key when finished. Sample Answer Key:

Review papers with keys.

B. Work through problems on own, when stuck for longer than 1-2 minutes on a problem, check solution and answer on key.  Then, go onto the next problem without the key.

C. Work through the easier problems on own, skip the harder ones. Then, watch the video to check answers on the easier ones and to learn how to solve the harder ones. Fast forward the video to the problems you need help with. Example Video Below:

D. Watch the videos in their entirely to learn how to solve the problems.

NOT an Acceptable Choice: Copy the solutions and answers from the key or from a friend. You will earn a bad grade on your next exam, the final exam and the AP® Exam.

  • Tell your elbow part which one you are going to choose and why
  • Can you switch later?  Absolutely
  • Can you start one way and then change?  Absolutely

Grading

Grade your students not only on completion, but also for following one of the choices. Rotate around the room to make sure they are on task. Accountability comes when students take an exam and know or don’t know how to do the problems.
