Here is a lab that has teenage scientists examining samples of their own blood under a microscope. Learners carefully prepare slides, then make detailed observations and identifying different types of cells using a key. 

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....

Students come to understand vocabulary words through pantomime. In this vocabulary lesson, students first review several vocabulary words and their meaning, then they work in groups to pantomime the definitions.

In this health worksheet, learners examine the human body and make mental connections to the target function highlighted in the sheet.

Students witness various stages of mitosis through preparing onion root tip slides. With teacher guidance, they learn a great deal through the hands-on process of preparing the slides themselves.

In this life cycle workbook, 3rd graders complete several different activities in which they analyze different invertebrates, identify arthropods, examine human biology and plants, and study natural environments. 20 different activities...

In this mini pond worksheet, learners create a mini-pond ecosystem with soil, water, and plant life. Students let their ecosystem sit for a day and they observe a sample the next day. Learners identify all the pond water microorganisms...

In this science worksheet, students use the diatoms present in water in order to test water quality and perform data collection and interpretation.

Students create their own environment. In this environmental protection instructional activity, students pretend they are the owners of a tropical island. They create jobs for the citizens and develop the island as a model environment.

Students examine the needs of trees and plants. In this forest ecosystem activity students use seedlings to investigate the basic necessities of plants. They discuss the consequences of these basic needs not being met.

Students examine protozoans and their advantages and disadvantages.  In this chemistry lesson students explain what a protozoan is then draw and label one. 

Fifth graders characterize insects and classify insects according to the Linnaean system. They use hand lenses or microscopes to examine insect body parts.

Students observe and examine the life cycle of antlions, recording their observations of the live insects in a journal. They view an antlion on a video microscope, draw the body parts, and replicate their experiment at home.

Seventh graders use technology to review cell structure and function. In this cells less, 7th graders review the parts and functions of a cell, and use photography/video and PowerPoint to enhance their explorations.

Students explore human senses. In this applied Science lesson, students utilize their senses to distinguish various objects. Students explain their descriptions.

Middle schoolers measure the size of an epithelial cell and to estimate the number of epithelial cells in a given area of the body. After watching a video on cells, student groups perform an experiment using a microscope to view some of...

Students design the test they use to examine, how the paramecium move, feed, and react to different types of stimuli such as a drop of vinegar. They conduct a lab experiment using a microscope.

Students explore pond ecosystems. In this living environment lesson, students observe the local pond and identify the living things they find by drawing pictures. Students observe organisms that were found in the pond by using a...
