Students explain how cells reproduce. In this biology lesson, students transcribe and translate a gene. They discuss and compare their answers in class.

There are technically two presentations in this collection of slides. The first presentation is a single-slide comparison of plant cell division and animal cell division. The second focuses on the steps of meiosis and the genetic...

Unifying themes in animal anatomy and physiology are displayed slide by slide.  The main concepts involve the differentiation in cells and tissues, and details are given about fuel management, metabolism, and some other essential...

Remind your middle school scientists how fox ear size varies depending on the climate they live in; large ears allow heat loss while small ears keep heat in. Discuss how a cold-blooded animal might try to regulate body temperature. Then...

To illuminate how afterimage occurs, create a star, square, or other geometric-shaped light for learners to look at for 30 seconds. Then, have them explain what they see as they shift their focus to a blank wall. A full explanation of...

In this musculoskeletal system activity, students review the function of bones and muscles in this body system. Students also review the different types of muscles: smooth, skeletal, and cardiac. This activity has 10 fill in the blank...

In this mammalian heart worksheet, students fill in the blank with information about the circulatory system and the process of cardian catheterization.

Here is a lab activity where teens experience the respiratory system first-hand as they dissect lungs and identify key structures within the system. Although the website is written in British English with some slightly different verbiage...

In this cell learning exercise, learners read a short passage about simple cells or ground cells found in stems and leaves of plants. Students then answer four questions about the text.

Students compare the organelles present in plant and animal cells. In this biology lesson, students create an analogy to easily remember their assigned organelles. They also research their function and write a creative story.

Young scholars discover the power of their heart and provide an opportunity to talk about ways to maintain good health. In this early childhood heart lesson, students diagram a human heart, identify exercises that promote a healthy...

Students study the parts of a cell.  In this chemistry lesson students complete an activity in which they make as much slime as they want. 

Seventh graders become more familiar with how our food is broken down mechanically and chemically. They also trace the food through the alimentary canal.

In this nutrition worksheet, students review the organs and enzymes that are part of the digestive system. Then students review the food pyramid by comparing two menus. This worksheet has 9 fill in the blank, 4 true or false, and 5 short...

Classify living things with a set of worksheets that has pupils sorting and indentifying living and non-living things. Learners use the worksheets as a basis for finding their answers. 

Put a new twist on your collection of optical illusion activities. Affix the linked printable spiral to a drill, record player, or some other rotating tool. Have learners stare at the spinning disk for only 15 seconds and then look away....

Students participate in an experiment to understand how robotic systems can estimate distances.  In this robotic ranger lesson, students measure the the time it takes for and object to move back and forth.  Students will use a...

Seventh graders trace a piece of food through the alimentary canal and differentiate between mechanical and chemical digestion in several different hands-on activities related to digestion.

For a plant unit in your biology curriculum, here is a slide show that bestows the basics of plant structure, reproduction, and classification. The information is general. The main point of the lesson is to highlight what characterizes...

Students identify parts of plant and animal cells and describe the functions of each part. They distinguish between plant and animal cells. After a lecture/demo, students perform experiments which help them construct models of plant and...

Sixth graders identify, locate and describe the function of the parts of a cell. In groups, they state the five stages of mitosis and put them in the correct order. They are introduced to the structure of DNA and mRNA and how they...

Students learn about cells. In this cells lesson plan, students take several days to learn about plant and animal cells and make their own edible cells with a cookie and icing.

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

Learners record information and write journal entries on the structure and function of cell organelles while viewing a Powerpoint presentation.
