Sometimes conservationists use specific plants to prevent erosion or fight invasive species. A 50-slide presentation covers both nonvascular and vascular plants. It discusses the plants, their stages and life cycles, reproduction, uses,...

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...

Get up close and personal with DNA! A two-part hands-on activity has learners extract DNA from a small organism and then their own cheek cells. Scholars then explore DNA replication using questions to guide their analyses.

Here is a lab activity adequate for use with any full lesson on environmental factors that shape animal adaptations or marine animal characteristics. Pupils will discuss the role plankton plays in the environment and filter-feeding...

It's hard to imagine that anything was missed on this five-page list of science roots, prefixes, and suffixes! Listed in alphabetical order, all are included in a single, two-column list. This may be especially useful for advanced...

Seventh graders view lab stations with Xenopus at different stages of development. They identify the life stage of the sample, as well as the previous and next stages. Students must explain their reason for selecting the specific stage.

Cell phones are likely made of gold—at least part of them! An interesting lesson explains the conventional and not-so-conventional uses of the popular element gold. From the Inca empire to modern-day technology, learners discover gold...

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

Teach young biologists the language of life with this series of worksheets on DNA. By working through these pages, students expand their understanding of genetics as they learn about the process of transcription and the...

Two blooms of phytoplankton, instead of just one, now occur in the Arctic due to declining sea ice, which will have widespread effects on the marine life and climate. In small groups, participants build an Arctic food web with given...

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.

Roy John Britten easily earned a PhD in nuclear physics—but he found painting with water colors too difficult. Young scientists learn about Britten's life, career, and research with an online interactive. They read a biography, view...

Students model the plasticity of neural pathways for memory in the brain. They simulate the cell activity according to dots on cards that they are given. They complete various simulations of different cell combinations.

Students extract their own DNA from cheek cells. In this biology instructional activity, students explain the replication process. They identify the structure and composition of DNA.

Learners observe the wealth of living organisms in a drop of water from our freshwater ecosystems. They classify the types of organisms observed as single-celled or multi-cellular and use a key or chart to identify and name the organisms...

Students make a mold using Plaster of Paris and then make a cast using that same mold. They pick a fossil and describe how it looks. They write a fictionalized story about its life, or burial. (

In this history of life worksheet, students complete a crossword puzzle by figuring out the vocabulary words associated with the 11 clues given. Then students review how paleontologists use fossils to learn more about past living things...

Students observe their own epithelial cells from the inside linings of their cheeks using DigiScope technology. They prepare a slide with both onion cells and epithelial cells and make an illustrated booklet for a PowerPoint presentation...

In this cell worksheet, students complete 5 word scrambles and 8 true-false questions about the characteristics of living organisms and compounds found within cells.

Students examine the basics of the nervous system through an interactive program. They discover how the brain is linked to muscle movement. They can test cells through the interactive program to see how it reacts to different stimuli.

In this living environment worksheet, students answer a variety of questions about living organisms, the processes they go through to make food and break down food, absorb nutrients, and release toxins. They explain homeostasis, they...

High schoolers observe how a cell uses an enzyme to rid itself of a poisonous substance by experimenting with hydrogen peroxide, potatoes, liver and carrots. They record the temperature and changes of the hydrogen peroxide as other...

Students calculate how much coal they use based on their electric power usage. In this environmental science lesson, students trace the history of coal mining in US. They write a letter to USPS to encourage them to create coal mining...

For this science worksheet, middle schoolers find the answers to various types of heredity problems. They use the sheet to set goals for completing the unit.
