If you've always wanted to know more about spreadsheets, here's a perfect resource for you. A self-paced tutorial introduces how to autofill and copy formulas in a Google sheet or Excel spreadsheet. It also shows users how to find range,...

How do viruses hijack our cells to produce more viral particles? Junior immunologists model how viral RNA integrates into a host cell's DNA using pop beads and use interactive tools to explore a virus' genome. The teacher's guide...

I can move about freely, but you cannot. The class models the movement through cell membranes by way of passive and active transport. Members of the class play the roles of various proteins, atoms, compounds, and cell actions and mimic...

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...

How do reverse transcriptase inhibitors work? Young virologists examine the function of azidothymidine, a drug doctors use to treat HIV patients, during a hands-on modeling activity. Groups create a strand of DNA from an HIV RNA strand...

When an organism eats, how does food become energy? Young biologists follow glucose through the process of cellular respiration to the creation of ADP using a discussion-based activity. The resource also highlights conservation of mass...

Can you describe a gamete without using the words sperm or egg? Scholars play a vocabulary review game where they try to get other players to guess their words. Each card has the target word as well as two related words they must not...

The first stage in the butterfly's life cycle is the egg. Young entomologists discuss why different butterflies lay different eggs and what their eggs look like. Then they use the handouts to make a replica of one type of butterfly egg...

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...

The t-test tutorial will fit your needs to a T. After calculating the mean, sum of squares, standard deviation, and variance of two data sets on a spreadsheet, scholars learn to calculate the t-values. They then learn to use the TTEST...

There's absolutely no error in using the tutorial! Learners use spreadsheets to create column or bar graphs with error bars. They also learn how to calculate the standard error of the mean in the tutorial. This is the third installment...

Spread your knowledge of spreadsheets. The first of five tutorials in the Spreadsheet Data Analysis unit introduces the basics of spreadsheets. It shows future data analysts how to organize and format tables, and how to use functions to...

How do temperature changes affect ocean currents? Scholars explore convection currents by demonstrating the flow of water in a baking dish. They use ice, heat, and food coloring to see currents. Then, they draw conclusions about their...

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.

Every muscle movement requires energy, but where does that energy come from? Scholars answer this question and more as they complete a worksheet. By following the directions, completing research, and discussing it as a class, they begin...

[Free Registration/Login Required] A site where students can label the cell cycle as well as take a short quiz on the topic.

Has explanations, illustrations, and a Quick Time movie to download. Also contains practice test questions that are answered online.

Poses and answers the question, "What is (and is not) mitosis?" An overview with images of the phases of mitosis, plus a mitosis animation.

Students compare and contrast passive and active transport by playing a game to model this phenomenon. Movement through cell membranes is also modeled, as well as the structure and movement typical of the fluid mosaic model of the cell...

Web-based activity provides an opportunity for students to study cellular respiration in an up-close and personal way. By following atoms and molecules through an interactive animation, they will be able to see the changes that take...

This site from the PBS production, Scientific American Frontier "Never Say Die", includes a section entitled "The Clock of Life". It provides a discussion of cell death through shortening of the telomere. A good class activity included.

This activity on Mitosis and Meiosis is designed to assess knowledge and understanding of important cell cycle processes, including mitosis and meiosis.

See how combining yeast, sugar, and water can demonstrate the carbon cycle and show how microorganisms work in the food chain.
