Scholars use a lab simulation to test contaminated yogurt for bacteria by gram staining. They learn proper lab procedures for handling bacteria and for sterilizing equipment, and then walk through the process on their own to try gram...

Get a better understanding of babies in the sea. The class learns about the two kinds of plankton. They then determine the baby pictures of eight marine animals given a picture of the adult and some hints about the larvae. When scholars...

Humans have only inhabited the earth for a fraction of the time that life has existed. Young scientists explore the facts about the emergence of life on Earth with an interactive resource. While highlighting different types of life, the...

The corona virus pandemic is indeed a historic event. A time capsule activity permits young historians to document these days of social distancing, remote learning, and quarantine by collecting artifacts that capture what their lives are...

Get to know all about sauropods from a paleontologist, Jonah. Following an introductory video, scholars choose from five fossils to learn more about. Each fossil begins with a video, provides information from several different...

One of the most diverse environments on Earth is the ocean. Young scientists explore the living things found in the ocean during an exciting seven-lesson unit. Their study includes organisms from plankton to invertebrates...

Students observe, over time, microbes such as amoebas, protozoa, rotifers and insect larva. They create a hay infusion culture using pond water then sample and record organisms found over a two week period.

Students grow grass or radish seeds in this experiment, which takes three to four weeks to complete. They become familiar with basic soil analysis techniques, as well as, explore the importance of analyzing soil samples.

Ninth graders participate in experiments to investigate the the effects of nicotine, caffeine, aspirin, alcohol, and sleeping pills on the heart rates of Daphina. They describe the relationships between common drugs and heart rates....

For this biology worksheet, learners are shown how to prepare a smear and then answer some review questions that address the proper preparation of a sample.

Students examine cell division and the process of mitosis.  In this cell reproduction lesson students grow yeast and observe the results, and learn about the career of scientific illustration. 

Learners examine how heating causes substances to expand, and cooling cause it to contract. They investigate the states of matter.

Young scholars grow crystals and document their observations by recording timeing and growth. Additional characteristics of crystals are observed under a black light, by growing under different conditions and mineral content is determined.

In a series of lessons, examine the impact on humans by microcosms in the biosphere. Among the plans structured for students with different abilities and learning styles, are activities describing the symbiotic relationship, drawing the...

Students determine the approximate time a cell spends in each phase of mitosis by counting cells in each phase from a prepared slide. They use a few simple calculations to estimate how long cells spend in each cycle in the body.

Ninth graders design and conduct an experiment. They evaluate other's experiments. Students describe relationships between biological systems and the environmental contaminants. They work as a team to solve a problem.

Students examine the characteristics of the Prairie Creek Habitat in Illinois. In groups, they travel between various stations writing haikus and reading brochures. They identify what occurs in each habitat and identify the animals...

Fifth graders, while in the computer lab, investigate and study the composition and level of organization of objects and organisms and utilize technology to collect and store information collected. They explore, research and examine a...

StudentsMatch the vocabulary terms in column A with the definitions in column B. Write the letter of the definition in column B in the space next to the terms in column A. Afterwhcich, students Write short answers or fill in the blank to...

In this physics worksheet, learners examine some of the historical theories of physics through the completion of 11 questions.

This laboratory activity is valuable practice in comparing features of different organisms. You could use it to introduce junior biologists to protozoans. The materials and procudures for the learners are simple, and analysis...

Imagine each one of your learners on task and interested in scientific material. Learners investigate science related art by creating a small museum! Using digital cameras, pupils photograph different scientific actions that look...

Written for Washington state students in life science, this lesson provides an opportunity to examine the residents of local freshwater habitats. You or the class collects a water sample, and learners try to examine what organisms live...

Preparing the root tip samples is the most challenging part of the mitosis-viewing lab found here, but the directions help ensure you have everything you need. There is no worksheet included; however, there is a sample data table....
