EARTH Lesson Drafts—2022

Float Away… How do we study the ocean?

Using comic strips to communicate how floats are used to study the ocean. In all stages of science communication, from childhood interest, to secondary education, to professionals and research, illustrators step in to translate the information into materials that fit the needs of individuals at every level of understanding. This lesson is intended as an […]

Floating with PUPCYCLE

PUPCYCLE (Phytoplankton response to the UPwelling Cycle) is a research project to measure the physiological responses of phytoplankton to upwelling. Upwelling tends to generate regions of high productivity in the oceans that can fuel phytoplankton blooms. Locating the microscopic phytoplankton that create these blooms can be quite challenging and scientists use a variety of methods, […]

Graphing pH

Graphing pH levels in the ocean and making connections to ocean acidification. Students will explore the topic of ocean acidification. They will construct, analyze and interpret a pH graph. Students will develop analytical thinking skills.

Graphing Temperature

Graphing temperatures in the ocean. Students will construct, analyze, and interpret real data from a profiling float in the ocean. Students will explore ocean temperature trends and climate change. Students will develop critical thinking, geographical, mathematical, graphing, analyzing, and interpretation skills.

Making the Invisible Visible

Have you ever wondered what sound looks like? How can we see sound? Students will be analyzing the spectrogram of an ocean soundscape and create their own spectrogram with a song of their choice. Students will practice the I2 strategy and develop their caption writing skills and graphical analysis skills. This lesson pulls info from […]

Ocean Checkup—How Do You Measure the Health of the Ocean

Argo floats, monitoring ocean health, dissolved oxygen, chlorophyll a Students will compare dissolved oxygen and chlorophyll a data collected at 3 different locations by Argo floats. Students will discuss the relationship between Chlorophyll A (phytoplankton) and oxygen in the sea, and discuss how the information would be useful in determining ocean health.

Ocean Data GOES from Space Argo the Sea

In this lesson, students will compare and contrast satellite data to float data. The first satellite was launched in 1962 and collected three types of data, with NOAA launching the first ocean-specific satellites in 1970. Floats were first built in 1980, and ARGO launches started in 1999, which collected ocean data. In this lesson, students […]

Our Ocean is Trending

What we can learn about the ocean’s oxygen and chlorophyll levels by using GO-BGC and SOCCOM Floats. What can students learn about the ocean’s oxygen and chlorophyll levels by using Argo and GO-BGC, and SOCCOM Floats? Students will learn how to access data from GO-BGC floats in order to analyze and compare properties such as […]

Phytoplankton + Productivity 5E

Students will be analyzing select GO-BGC float data to find a connection between chlorophyll-a and dissolved oxygen

Profiling Phytoplankton

Students will learn about different phytoplankton and what impacts their distribution by building a water column representing the Southern Ocean. Students will build a water column that showcases the different types of phytoplankton found at different levels of the Southern Ocean. We will be using data collected from a 2014 Antarctic cruise on the Nathaniel […]
