A great way to learn about molecular structures is to make a model. Gumdrops and toothpicks are used to construct crystal models. The models are based on theories of crystal shapes that occur because of positive and or negatively charged...

Create your own karyotypes with clay in a kinesthetic genome activity. This tactile experience was created for visually impaired pupils, but can be used for all hands-on learners who are beginning to study chromosomes. The preparation...

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...

Students explore animal and plant adaptation.  In this ecosystems science lesson, students view websites to gain information about plankton and its  interdependence within ecosystems. Students identify ways in which plankton...

In this models worksheet, students read about how models are used to communicate events or principles in science. They are given an example and answer 4 questions about models. They discuss accuracy and inaccuracy of models. They create...

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.

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.

Young scientists study the construction of a battery through experimentation. They engage in five experiments which combine to create a thorough study of the history of batteries beginning with a model of the first battery.

All of the people in your class would agree that life would be different without the invention of the telephone! Study Alexander Graham Bell's most famous and influential invention through the primary source document of his...

Eighth graders construct edible models of a plant cell and an animal cell and state the functions of the organelles. They are to write a short sentence describing the function of each organelle.

Fourth graders, in groups, explore cells, the basic unit of all living things.

What is in that double helix? Explain intricate concepts with a variety of creative activities in a lesson that incorporates multiple steps to cover DNA structure, nucleic acids, and proteins. Pupils explore the history of DNA structure,...

How does energy from the sun make plants grow? Scholars move step by step through the processes that promote plant propagation during a detailed lesson. The resource illustrates ADP production and hydrolysis, then allows learners to...

Learners model the transmission of neural impulses with dominoes. In this nervous system lesson, students construct a device with dominoes. They use the device to model the way a nerve impulse is propagated from dendrite to axon.

Sixth graders investigate scale models of toys.  For this scale models of toys lesson, 6th graders bring in toys from home to measure.  Students discuss scale and what scale is used with their toys.  Students determine the...

Fifth graders study the structures of a plant cell and animal cell. They create a graphic organizer and a food model. Finally, they write an essay comparing and contrasting plant and animal cells.

Students define the key terms that are the structure and function of DNA. In this genetics lesson students complete a lab activity in which they construct a model DNA structure.

Learners in an alternative school setting for pregnant teens examine various facets of pregnancy including prenatal and postpartum testing, genetic influences, and additional risk factors. Through videos, hands-on activities, and small...

Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

Students are introduced to the members and workings of a honey bee colony. They describe the structure of a comb, the day-to-day activities of honey bees, and name the four stages of bee development. They construct a honeycomb model.

The climate at the equator is hotter than the climate at the poles, but why? The lesson goes in depth, explaining how the angles of illumination relate to the heating rate at different latitudes and seasons. Scholars use a strong lamp,...

High schoolers construct models of microorganisms recognizing size relationships-comparing the size of viruses with the sizes of bacterial and eukaryotic cells. They put into perspective just how small microbes are by comparing the size...

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...

Students draw a diagram to show the fluid mosaic model of a membrane. They explain how hydrophobic and hydrophilic properties help membranes hold their shape. They identify the functions of different cell membrane proteins as well.
