Seventh graders demonstrate the processes of science by posing questions and investigating phenomena through language, methods and instruments of science. They study the body features or systems of several animals.

For this respiratory system: breathing worksheet, students read through the given notes. Students then compare the different respiratory systems with that of an earthworm, fish, insect, and frog.

Pupils investigate the following scientific terms and ideas: rates of diffusion, the role of morphogens in the development of larva, the chemical dynamics of a cell, and the significance of embryo polarity during development.

For this tissue worksheet, high schoolers are given notes on 6 types of epithelial tissues, 10 examples of connective tissue, three types of muscular tissue and the components of nerve tissue.

Tenth graders review the Energy, Matter, and Organization unit. They have one week to complete an essay. Students must submit a concept map or drawing. The activity is introduces by reading a short story line which presents a simple...

For this ethyl alcohol worksheet, high schoolers read about the characteristics of ethanol including the effects it has on the body when ingested and digested. This worksheet has 2 short answer questions.

Even though they were written for upper-level high schoolers or college pupils, the labs herein are possible to use even in middle school. In the activity, kids observe osmosis in both potatoes and elodea plants, then record and graph...

Learners examine the hierarchy theory and biotic organization by playing a teacher-created card game matching groups of items, such as organelles, in suits of four. They discuss the reasons for their hierarchical organization of the...

Fifth graders explore osmosis as they watch organisms divide.  In this organism lesson, 5th graders use potatoes to experiment with the effects of salty water in the body.  Students discuss what osmosis is and record what...

Fifth graders become familiar with how the diaphragm expands to draw air into our lungs and contracts to exhale carbon dioxide. They also label the major parts of the respiratory system through the use of interactive Internet research...

In this biology learning exercise, learners look at the function of filtering in the nephron of the kidneys and the biochemistry is emphasized.

In this homeostasis and plasma membrane worksheet, 9th graders identify and solve 11 different vocabulary terms and definitions. They review the definitions of the words listed and then use the clues to complete the puzzle shown....

Students investigate atomic and nuclear structure of matter by researching historical atomic theories. Students examine Rutherford's studies and discover that many scientific conclusions change over time as new data is collected.

In this literacy worksheet, students find the words that are in the word search puzzle that focus upon the vocabulary that is from the theme of the sheet.

This seven-page Biology course handout gives a detailed explanation, accompanied by many illustrations, of the various processes by which substances travel across the membranes of cells.

For an organism to function, substances must move into and out of cells. Three processes contribute to this movement - diffusion, osmosis and active transport. Diffusion is the process by which useful materials and waste products move in...

Explains the processes of osmosis and diffusion using labeled illustrations, discusses how they occur and gives examples.

[Free Registration/Login may be required to access all resource tools.] The process of molecules moving from an area where there are lots of molecules to an area where there are fewer molecules is known as diffusion. The diffusion of...

An interactive demonstration where students make observations of the process of diffusion. Students draw and record observations, make predictions, and make comparisons between what they're observing and how a cell membrane works.

Learn about diffusion, osmosis, dialysis, and active transport in this college textbook. Section also includes how to calculate the rate of diffusion. Section includes problems and questions for the students to answer to ensure...

This lesson explains the process of facilitated diffusion, explaining that it is a passive form of transport which uses protein channels to move larger molecules down their concentration gradient. It is 3 of 9 in the series titled...

This lesson explains the process of facilitated diffusion, explaining that it is a passive form of transport which uses protein channels to move larger molecules down their concentration gradient. It is 4 of 9 in the series titled...

This lesson explains the process of facilitated diffusion, explaining that it is a passive form of transport which uses protein channels to move larger molecules down their concentration gradient. It is 5 of 9 in the series titled...
