Students determine the approximate time a cell spends in each phase of mitosis by counting cells in each phase from a prepared slide. They use a few simple calculations to estimate how long cells spend in each cycle in the body.

Investigating the large numbers of science is the task in a simple but deep activity. Given a one-sentence problem set-up and some basic assumptions, the class sets off on an open-ended investigation that really gives some...

Learners distinguish the differences between Prokaryotic and Eukaryotic cells. Using microscopes, they examine a variety of plant and animal cells. Working in groups, they draw and label plant and animal cells and show the mathematical...

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,...

Students investigate the cycle of mitosis. In this biology lesson, students discuss the different stages of mitosis through cell reproduction. They further their investigation through laboratory analysis.

Just how fast does bacteria grow? Over the course of three lessons, pupils investigate exponential growth with the use of bacteria growth. During the lesson, bacteria from a cell phone is grown to make a connection to real life. Using...

Students explore biology by identifying a diagram. In this cell anatomy instructional activity, students read a story about archeology and conduct a fictitious archeology dig in class in which they search for animal cells. Students...

Students identify the different types of fractals. For this geometry lesson, students use math to analyze different biological phenomena. They collect data from the experiments and construct graphs.

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 conduct experiments with plants.  In this photosynthesis lesson, students examine plants under different types of lights.  They calculate the amount of dissolved ocygen concentration and compare it to the formula for...

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...

Students apply a data set to create a graph show how iron ore impacts an ecosystem. They explain how the iron effects the distribution and abundance of phytoplankton in coastal ecosystems using spreadsheet software.

Students examine and compare traits of humans and crocodiles.  For this crocodile lesson students use a ratio to estimate the height of a person and compare that to a crocodile. 

In this quantitative analysis worksheet, 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...

Students explore how a cow digests the grass they eat. In this science/math lesson, students compare the quality of forage. Additionally, students determine the effects of rangeland health on the production.

Students construct a geologic timeline the size of a football field. They work in small groups to calculate the yardage for significant events in the Earth's history and then as a class pace out all of the events.

Students read an article that explains the applicability of scale in the biological sciences field.
