Would you believe that your digestive system stretches to five times your height?! Help your pupils to understand this relationship as they work through the laboratory exercise. The first instructional activity of a 12-part series is a...

Create a protective protein shell as a package. Using the included template, pupils tape together 20 triangles to create a 20-sided shape to represent the protective shell of a virus. The model of the protein shell incases the nucleic...

Students use microscopes to study live fish embryos and animated diagrams of cell division on the Internet. They see that scientists rely on technology to enhance the gathering and manipulation of data. They create web pages on cloning.

In this biology worksheet, students construct a model of a plant or animal cell using edible materials that will remain fresh at least three days. They identify and label each part to include various organelles as listed. Students also...

Seventh graders describe the processes involved in mitosis and meiosis. In this life science lesson, 7th graders create chromosome models using strings and beads. They play a jeopardy team game at the end of the unit to review concepts...

Students investigate energy using a photovoltaic cell. In this electricity instructional activity, students collect data from current-voltage and power-voltage curves to determine if photovoltaic systems have an advantage over...

High schoolers are able to answer basic questions about the process of turning light energy into electrical energy. They are introduced to the basic physics and chemistry behind the operation of a solar cell. Students explore how a...

Students examine the behavior of living cells treated with different types of stimuli. They watch an online movie, examine wet mount slides under a microscope, take an online quiz, and analyze data.

In this quantitative analysis activity, students explore the limits of a rate equation. They use quantitative analysis methods to determine the differential, plot graphs of their values, and describe the relationships between the...

What was the Untied States like in 1938? What were the concerns of Americans in the post World War I era? What were their fears? What were their sources of news and entertainment? To understand the reaction to Orson Welles' radio...

Tenth graders are introduced to the cell and some of its parts. Through the use of video, 10th graders see animal and plants cells and their parts. They learn terms used to explain the cell.

Fifth graders examine how a red blood cell travels throughout the body. Using a model, they recreate the flow of blood through the heart. They also label the lungs and the differece between the blood that enters the heart and the blood...

Seventh graders analyze and identify the role of the cell membrane and nucleus. They create flash cards to help them review cell structures. They also compare plant and animal cells.

Young scholars understand how various cell parts function and how they are related to the genetic process by creating a model and symbol to depict the function of the cell parts. They research a cell part to determine function and then...

Young scholars identify cell parts and their function. In this animal cell instructional activity, students view a video clip and discuss cell components. Young scholars create an edible replica of an animal cell using food items.

Students create DNA models. Using puzzle pieces to represent the parts of a DNA strand, they put together a segment of DNA. Once everyone has completed their individual strand, they being linking with other students using tape. Class...

How do some viruses spread so quickly, and why do they make us feel terrible? Answer these (and many more) questions through a simple yet impactful lessons. Pupils observe demonstrations that show the two methods viruses use to escape...

With instructions to adapt the activities for any grade K-12, any teacher can incorporate the concept of scale into the classroom with a simple, yet effective lesson.

How do doctors fight a virus that's constantly mutating? Show science scholars how we fight HIV using one of its own most fundamental processes through a thoughtful demonstration. The lesson focuses on how protease inhibitors prevent HIV...

Silver: more than jewelry, it's also a natural antimicrobial agent. An inquiry-based lesson asks collaborative groups to design and implement an experiment to test this property. Using samples of silver nanoparticles and a strain of...

Introducing exponential equations means learners need to take all the rules and tricks they learned for exponents and actually apply them. This presentation comes to the rescue by touching on changing bases in exponential...

Students create and test a hypothesis about cell division. After observation of Frog Egg cell division, students write obervations and refine process and hypothesis. The use of scientific method, group work and inquiry are fostered by...

Two sequential parts to this lesson introduce your class to the electromagnetic spectrum, the ability to absorb radiant energy, and the pigments in leaves that are responsible for collecting sunlight to be used in the photosynthetic...

Learners examine the basic structures and functions of cells. They design and construct a factory cell model where each factory part corresponds to a cell part.
