Students study acids and bases and the uses of indicators. They interpret the actions of an indicator to conclude that bromothymol blue turns yellow in the presence of a weak acid.

High schoolers create and display a scientific poster in the same format that scientists use at a research symposium. They compile data and make conclusions about the classification of the Arizona Hedgehog Cactus as an endangered...

In this cell worksheet, learners will match 13 vocabulary words relating to cells to the correct definition. The cell vocabulary words cover all the parts of the cell plus eukaryotes, and prokaryotes.

In this theory of evolution worksheet, students review vocabulary words associated with evolution including the different types of evolution patters. This worksheet has 5 true or false and 5 matching questions.

Young scholars recognize the importance of plants as they perform an experiment involving photosynthesis. Students determine the optimum wavelength of light for photosynthesis by exposing plants to different colors of light, collecting...

You don't have to be a scientist or even out of high school to contribute to scientific research. In the 12th activity in the series of 21, scholars use this opportunity to add to the growing body of scientific knowledge and consider the...

The debate over genetically modified organisms is on! Young biologists imagine that they have been asked to choose which corn chips will be sold for a fundraiser, one made with GMOs or one without. This four-day lesson plan requires...

The general characteristics that affect classification of fungi and other organisms in the domain Eukarya are detailed for the students on 12 attractive slides.  Teachers can access individual slides to cover life cycles or...

Provide your class with the opportunity to view our carbon cycle close up. Young scientists research the cycle of oxygen as it completes the tasks of photosynthesis and respiration. They explore the importance of carbon in an ecosystem...

Each of these slides deals with an individual organelle and displays a diagram along with labels of the structures. The most useful components of this slideshow are the summaries of functions and descriptions of how the organelles are...

Now you have a new excuse not to do your homework. A long-term experiment has learners explore cellulose-digesting enzymes. They simulate how paper breaks down in a compost bin. There's no need to blame your dog for eating your homework...

Equip young campers with important survival knowledge with a set of engaging lessons. Teammates work together to complete three outdoor activities, which include building a shelter, starting a campfire, and finding directions in the...

A fantastic presentation with great images should improve student understanding of lipids and their involvement in the body.  The chemistry of different fats, phospholipids, and steroids are explained. Additionally, the specific...

As an anticipatory set, biologists listen to the story of Ruth Patrick, a scientist who used algae to detect water quality. They observe a demonstration of osmosis and diffusion. In their lab groups, they place Elodea stalks in...

Budding biologists often ask how scientists know what they do about different topics. In the lab described here, they have a chance to find out first-hand about the requirements for photosynthesis. Three sequential investigations are...

Breathe some new life into charcoal. Scholars use biochar to improve soil fertility. They test the effectiveness of this addition by conducting an experiment with soil having 0%, 2%, and 4% biochar.

Investigate the relationships between different deep-sea organisms by DNA sequencing. A worksheet provides instructions for DNA sequencing and space to work. They simulate gel electrophoresis by cutting out paper "DNA strands."...

The general characteristics of fungus types are presented here. Your class will love the pictures of the amazing features found on these strange living things. The internal and external structures and their functions are highlighted. By...

What a web we weave. Pupils use yarn as the primary resource to create a web depicting the intricacies of a salt marsh ecosystem. They participate in a question and answer session, which leads to an in-depth facilitated discussion...

Searching for an activity that allows emerging biologists to explore symbiosis up close and personal? Pupils collect samples and view lichens through a microscope and conclude with a discussion about the relationship they have...

Brown rice contains vitamins B and E, while white rice lasts longer in storage. The availability of rice around the world makes it a great candidate for genetic engineering. Scholars apply their knowledge of genetic engineering to solve...

Learners investigate the effects of pollution on marine ecosystems. They read and discuss an article, identify the effects of pollution on marine life, conduct research on local nutrient pollution, and conduct local water quality studies.

Scientists recently discovered several previously unknown species at the Bear Seamount off the coast of New England. Scholars research these new species — benthopelagic, benthic, and seamount fish — and find out what makes them...

High schoolers evaluate a forest for timber harvest and discuss potential impacts of logging. In this sustainable forestry lesson, they work in groups in a forested plot to choose trees to cut based on species and stem diameter and then...
