You're only 10 minutes late? Do you know how much the universe has expanded in those 10 minutes? Scholars graph supernovae based on their redshift and see if the results verify Hubble's Law. If it does confirm it, the universe is...

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...

Young scholars discover that all living things have a life cycle in which they are born, reproduce and die. In groups, they examine and analyze the changes that happen during the lifespan of a human. To end the lesson plan, they...

Multiple choice, fill-in-the-blank, short answer, and matching questions are all here in a multi-page activity or quiz. While the formatting leaves a little to be desired, it would take just a few minutes to change the handout into a...

Want to hear a joke about sodium? Na. Young scientists test various materials to identify if they include protein, starch, and glucose by using the Biuret test, iodine starch test, and Benedict's test respectively. After practicing with...

Discover how copying nature can be beneficial to humans. Scholars read articles about examples of biomimicry and its potential applications. Along the way, they learn about Nature's Nine Laws and how they relate to biomimicry. This is...

Energize the cells of young biologists with an edible life science activity. Engaging students in exploring the inner workings of plant and animal cells, this activity involves using colored jello and various sweet and...

Coloring pages showcase microbes—bacteria, viruses, and protists. Scholars have the option to download a coloring book and scavenger hunt or color the page directly on the computer. Three paragraphs describe each microbe. 

Students develop an understanding of our planet as a system by designing a very-long-duration space mission in which the life-support system is patterned after that of earth.

So, this is not technically a worksheet, but rather a chapter of reading material, pictures, and diagrams introducing young biologists to the cell. Cell theory, diversity, size, and shape are described. The internal organization and...

While all learners need to know the benefits and responsibilities of working in a small group, this presentation and its vocabulary are geared toward a late high school or early college student. Why do we study in small groups? Why do...

The concept of a how pesticides and other chemicals pass through a watershed can be difficult for younger learners to grasp without a concrete example. In the activity here, some blank paper, markers, and a spray bottle are all you need...

How does nature's hierarchy relate to our local human environment? Answer this question, along with others, as the class visually depicts the natural hierarchy provided by nature. Pupils discuss each piece of the pyramid and its energy...

Getting water to a tap requires an understanding the fundamentals of fluid flow. Groups design, build, and test a piping system to get water from the source — a five gallon bucket — to a tippy tap. The objective is to be able to...

We all know limestone weathers, but what affects the rate of weathering? Young scientists investigate the physical and chemical weathering of limestone (chalk) through experimentation. First, they conduct trials with different-size...

Using a miniature coral reef aquarium kit, young ecologists model this unique ecosystem. They research various coral reef organisms and their niches, and they culminate the project by working together to write a report. Use this activity...

Is health care a right or a privilege? Scholars review pro and con arguments to decide if all Americans should have the right to health care. They also watch informative videos and review information on the United States and...

Are we alone in the universe? This brief informational text on extraterrestrial theory has been split into seven sections to help scholars practice note taking. They read the statements, underlining key words. Then, using the graphic...

Students are introduced to the GIS system. They create a map plotting local sites the Environmental Protection Agency has on its EPA Regulated Sites list. They identify a list of schools that are near potentially hazard sites.

Students identify the different kinds of blood. In this biology lesson, students investigate the antigens, agglutinins and Rh factor using their own blood. They use Punnett squares to predict blood type of offspring.

In this going places worksheet, students read the passages provided and answer the given questions. Students answer questions as it relates to the skeletal system, puberty, and microorganisms.

Pupils examine an effect of zero gravity on the human body using a baby food jar, balloons and a jar with a large mouth.

High schoolers develop a model to visually observe the change in blood flow rates between healthy and unhealthy arteries. They calculate data that they have collected and graph their results. They determine the relationships the flow...

Students explore the pros and cons of the selling of body parts in this lesson. A discussion of how personal value systems impact science and research is developed.
