Powers of two: it's a matter of doubling. A short summative assessment task asks pupils to determine a process to calculate the number of cells at given time intervals. They use powers of two in order to calculate the number of...

It has been decades since the discovery of DNA. Still, activities such building this DNA model allow blossoming scientists to better understand the components that form this overall structure. During this activity, they will also...

Aquapores allow water to travel through cell membranes while keeping other molecules out. The animation offers an up-close look at these parts of the cell membrane. It explores multiple vantage points and shows the importance of these...

The proteins inside a cell determine the shape of the cell. While most red blood cells have a circular shape, those with sickle cell take the shape of a sickle. This change in shape causes multiple issues in the system. Scholars solve...

It's not easy to find fabulous physics lesson plans, but School Power Naturally has put together a series of them. In this particular lesson, high schoolers learn about the structure and functioning of photovoltaic cells. They construct...

Learners create electricity. For this solar energy lesson, students role play how photovoltaic cells change sunlight into electricity.  Learners discuss the experiment and create their own diagram of the model. 

Pupils learn about both male and female anatomy before understanding how they work together to make a baby. Scholars discover new vocabulary, create a presentation on fertilization, and discuss related topics.

Different types of mutations cause unique types and degrees of muscular dystrophy. Scholars learn about the types of mutations and the impact on the body. They compare the location of the mutations and draw conclusions about how it is...

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...

Ecosystem, human body system, weather system. We hear the word system a lot, but what does it really mean? In the activity, pairs or groups of learners discuss how a bicycle is a system and then analyze objects in their classroom and...

Where does the mass for a growing tree come from? Scholars consider a few different hypotheses and guess which is correct. They then analyze data from different experiments to understand which concepts science supports.

Students create three-dimensional cell models. They may choose to make either a plant or animal cell but must use a Ziploc bag as the cell membrane, slime for the cytoplasm, and strawberry baskets for the cell wall if making a plant...

Fifth graders examine plant and animal cells. For this plant and animal cell lesson, 5th graders define what cells are, label their parts, and describe how plant and animal cells are different. They observe cells at a number of web...

Students identify that yeast are a single celled fungi that are a great model organism for studying respiration in the classroom. They also fill the bulb of a disposable pipet (eyedropper) with yeast, then submerge the pipet in a test...

In this cell analogy worksheet, learners are given a story about a city that produced widgets. They compare this to a cell and identify the parts of the cell that are analogous to the parts of the city. They then create their own cell...

Students define the parts of a cell and make a model.  In this cells and organelles lesson plan, students construct organelles from supplied materials.  Students describe the parts of their constructions.

In this cosmic rays and solar cells worksheet, students read about how cosmic rays damage the electrical output of solar cells over time on satellites. Students use a graph of the solar power output compared to the year for the SOHO...

Students study photovoltaic technology. In this photovoltaic technology lesson, students simulate a photovoltaic system. Students discuss how to simulate a cloudy day.

Tenth graders explore the parts of a cell. In pairs, classmates construct a model of a eukaryotic cell, detailing its morphology and function. With the use of computer technology, 10th graders create cell book for middle schoolers. ...

Like a fresh canvas, stem cells can turn into almost anything. In a comprehensive lesson plan, high school biologists use clay to build a 3-D model of cell division and the processes that occur during the first 14 days of development....

Young scientists learn about plate tectonics and the three different types of faults (normal, reverse, and strike-slip) using foam models. The activity also covers common types of locations where these faults are found.

Emerging electricians extend mental models of light bulbs and resistors in series and or in parallel circuits to include the connection of photovoltaic cells in arrays. They investigate open circuits, using a DC voltmeter, a light...

DNA molecules hold the secrets that make us unique. The fourth of 12 lessons explores the structure of DNA by building candy models. After building the models, young scientists break their models to begin the process of DNA replication....

Students examine and research the parts of a cell, their functions, and life processes. They simulate how cells receive nutrients using coffee filters, water, and coffee, and construct cells using pudding, cookie dough, and candy.
