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 bacteria worksheet, students fill in the blanks with the correct word. Students then label the structures found on a bacterium.

In this biology activity, 9th graders identify and locate various vocabulary terms pertaining to the study of biology. There are 50 biology terms located in the word search.

Sometimes it's okay to eat your science experiment. A hands-on activity has pupils create models for algae to learn about its cellular structure. The best part of the experiment? The resulting juice-filled gels are edible—yum!

Young scholars use various snacks to make large models of human cells. Items such as gumballs, gummy worms, and jelly beans represent the nucleus, golgi bodies, and mitochondria. As each piece of candy is added, the teacher explains what...

Students do an experiment using a microscope. In this lesson plan, about cells, students examine different slides using a microscope. Students look at an onion skin, cheek cells, and potato cells. In each of these, students find cell...

Has your class ever been astounded by the complexity of DNA analysis? Have they ever asked why genetic engineering has become so important to our daily lives? Young scientists perform DNA extraction on strawberries and explore how the...

A slideshow that covers the all-important details related to basic human circulation. The reasoning for exchange of material methods is presented and then labeled diagrams of the main human transfer systems are shown, along with...

Find out just how enticing learning about neurons can be by creating models with sugar cookies, icing, and candy. With great background information for you and an easy procedure for the kids, studying cells has never been more fun or...

Put your heart into it. Scholars design and build replacements for mitral heart valves. Obviously, they can't test their creations on a real heart, so a box with marbles (to represent blood cells) will suffice.

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...

Although these slides are text rich, the summaries of prokaryote characteristics will be useful. There are diagrams of preferred cell conditions and your students will find all the basic definitions of structure and functions...

Tic-Tac-Toe is a game most students will be familiar with. This fun activity prompts students to answer questions about cells organelles in order to place a mark on the grid. There are some non-essential humorous sound effects and...

In this biology learning exercise, students answer questions.

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...

In this internal systems and regulation worksheet, students correctly decide if given statements are true or false. Students apply information learned about the circulatory system to the given statements to determine statements of truth...

Young scholars study chloroplasts, their structure and evolution.  In this photosynthesis lesson students experiment with polarized light and the production of chlorophyll.

High schoolers explore the relationship between pressure and vessel diameter. They are given an open-ended design challenge in which they engineer their own remote repair device. Students see a model that represents how elevated blood...

In this electronic worksheet, students complete 4 short answer, 6 fill in the blank, and 4 term identifications about electronics.

In this prokaryote instructional activity, students answer ten questions about prokaryote cells and they color a diagram of a simple bacteria cell and its structures.

A note-taking resource for the topic of transport between cells. If formatting is important to you, there are some slight changes you'll need to make to this Word document to make it consistent. 

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...

Students experiment with DNA by isolating it from plant tissue. They investigate whole onions to prepare DNA. They complete the experiment to examine the structural characteristics of DNA.

Sixth graders, in groups, learn the morphology and function of organelles within plant and animal cells.
