The main characteristics and definitive features of red, green, brown, and 4 other algea are listed along with great photos and examples. The details involved with reproduction styles, and information about traits of each Phyla are...

Marine biology beginners learn about the different types of seaweed in this collection of slides. It covers the general structure of seaweed, and then describes the differences among green, brown, and red algae. The presentation...

Young scholars explore ocean biology by participating in a plant growing activity. In this seaweed lesson, students identify the importance and uses of seaweed in the ocean and examine different seaweed samples. Young scholars utilize an...

Students participate in an experiment in which they test the growing rate of algae. They test the algae in different elements recording their observations. They share their results with the class and discuss.

Students discover that seaweed/algae is a small part of the resources the oceans provide. By investigating common household products, students discover that human senses are not enough to detect the presence of seaweed/algae in food.

Students explore algal blooms.  For this ecosystem and health lesson, students define and describe harmful algal blooms, then discuss ways in which the impact of these algal blooms could be reduced.  Students work in groups to...

Students explore various types of algae found in Hawaii. In this science lesson, students research species of the three types of limu and identify various uses. Students explore products that contain limu.

Students demonstrate that, although we sometimes can neither smell nor taste them, many ingredients in our foods and household products come from the sea. They also investigate food eat to determine algae derivatives they contain.

In this algal blooms worksheet, students order the stages of a red tide. They answer two short answer questions. Students define three terms relating to algal blooms.

Students compare and evaluate the world's different seaweeds.  In this investigative instructional activity students study seaweed and the harvesting of it.  They then interpret the data collected and graph the seaweed...

Students explore limu diversity. In this ocean ecosystem lesson, students classify limu according to its physical properties. Students work in small groups to generate scientific observations and sort limu by characteristics.

More than 200,000 species of protists exist, living on land and in water around the planet. Scholars view the diversity of protists in an interesting presentation. It divides protists into three groups: animal-like protists, plant-like...

What happens when ice melts? Well ... water happens. When that melting ice is a glacier, the amount of water that results produces change throughout the world. Middle school science sleuths uncover the truth about global...

Ginkgo trees existed for more than 350 million years, and, at this time, only one species still remains. While plant diversity generally increases over geologic time, some interesting exceptions occur. Young scientists learn about plant...

Learners calculate the total percentage of samples from the data on the graphs. In this marine science lesson, students analyze the concentration levels over a period of time. They suggest ways to lessen the effect of these blooms.

In this science activity, students use basic scientific concepts to complete the series of puzzles about protists and fungi that are intended to increase science literacy.

A marine environment covers the majority of the earth but is arguably the least understood. Teach young scientists about the characteristics of oceans and ocean species using an interactive online lesson. The in-person or remote learning...

In this protist worksheet, students complete a crossword puzzle with 34 questions about the behaviour and different types of protists.

With this collection of slides, future biologists get to view photographs of protozoans from different phyla. Interspersed with the photos are bullet-style notes listing characteristics of each group. Unfortunately, most of the pictures...

Learners study what worms need to survive in different environments. They study how worm composting improves soil and reduce waste. They discuss composting techniques and present a puppet show about a worm's life.

Students explain the importance of chlorophyll in plants. In this biology lesson, students extract chlorophyll from different plant sources using chromatography. They discover the different factors needed for photosynthesis to take place.

Students examine the differences between cellular respiration and photosynthesis.  In this cellular processes instructional activity students complete a group lab activity to see how climate change affects their lives. 

Students investigate how plants absorb carbon dioxide during photosynthesis. In this biology activity, students differentiate photosynthesis and cellular respiration. They discuss the important role of plants in the environment.

Learners read or have the book A River Ran Wild read to them. They discuss and reflect on the messages presented in the book. Students use their listening comprehension skills to draw conclusions. Learners articulate several examples of...
