In this worksheet on the life cycle of the butterfly, students look at 4 pictures representing the life cycle stages, and choose words from a word box that match each picture. Students then number the pictures in the correct order of...

Welcome to Biology! Introduce pupils to a subject conceptualized by Aristotle in 300 BC through a presentation and worksheet. It covers the themes of biology, characteristics of life, the scientific method, microscopes, and measurements.

Observe onion root cells undergoing mitosis underneath a light microscope and determine the phase of mitosis the cells are in. High schoolers draw a sketch of the mitotic cells, explore why cells undergo mitosis and learn how...

From the scientific method to the function of a cell, the eBook has it all. A useful resource provides a free biology textbook with a focus on context. The text begins with an overview of the process of scientific inquiry and biology...

Just because we can't see it doesn't mean it isn't there! A growing concern for environmental scientists is toxic nanoparticles in our air and water. Young scholars conduct an experiment to demonstrate how these particles can cross our...

There are some amazing ways species evolve to survive. From large ears to sneezing salt, learners read about these interesting adaptations in an interactive lesson. Great to supplement an in-class lesson, it also works well as a remote...

Proving microscopic structures exist is a difficult task. Learn how scientists did just that in the mid-1800s as they set out to identify the cellular structures related to genetics. The online lesson explains the collection of work that...

As a way to combine life and physical science, or simply as an investigation of plant transpiration, this activity is sure to inspire! Middle schoolers capture the moisture given off by plants that are placed in different conditions....

The climate at the equator is hotter than the climate at the poles, but why? The lesson goes in depth, explaining how the angles of illumination relate to the heating rate at different latitudes and seasons. Scholars use a strong lamp,...

How do viruses hijack our cells to produce more viral particles? Junior immunologists model how viral RNA integrates into a host cell's DNA using pop beads and use interactive tools to explore a virus' genome. The teacher's guide...

Learn about plants and pollination with a worksheet about the parts of a flower. After labeling the anatomy of a flower using a word bank, kids explain the difference between self-pollination and cross-pollination, and unscramble...

Believe it or not, biodiversity exists even in areas of disturbed habitat. An interactive activity challenges learners to look for species with a magnifying lens in an image of a city habitat. Pop-up images and descriptions explain how...

After studying DNA replication and the genetics of inheritance, this slide show is useful for explaining specific mutations that can happen and result in an illness. Sickle cell anemia, and cystic fibrosis are explained on a genetic...

How do doctors fight a virus that's constantly mutating? Show science scholars how we fight HIV using one of its own most fundamental processes through a thoughtful demonstration. The lesson focuses on how protease inhibitors prevent HIV...

What is one of the most exciting parts of a butterfly's life cycle? When it emerges from its pupa and dries its wings! This is a great activity little ones will love. They discuss what happens during the pupal stage of the butterfly life...

Does your class have a bright future in the solar energy industry? Science scholars take an in-depth look at what's new in solar technology. After completing research into the solar industry, participants create and market a product in...

Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

Students create and observe coacervates. In this origin of life lesson, students create coacervates by mixing carbohydrate and protein solutions. They observe the life-like qualities of the structures and discuss the origin of life.

Students investigate living creatures that inhabit a pond and explore how various organisms satisfy their needs within their environments. In this life in a drop of pond water lesson, students examine microorganisms under...

For this cell cycle worksheet, students review how enzymes control the cell cycle and what happens when the cell cycle becomes uncontrolled. This worksheet has 7 short answer questions.

For this arthropod life cycle worksheet, students will use a diagram showing the 4 stages of butterfly metamorphosis to complete a table describing each of the stages.

Lead your biology class on a cell-sized adventure! Emerging scientists construct models of prokaryotes, then design an experiment to properly grow a bacterial culture. They conclude the activity by viewing the culture under a microscope....

The intent of this slide show is to introduce young biologists to evolution, specifically how populations change through time. The content does not support the stated objective. What you will find in this presentation is general...

At one point, all mammals carried only two color receptors, but now most humans carry three. An informative presentation and hands-on activity demonstrate how this evolved through genetics. By participating in the activity, pupils...
