Take your biology class' understanding of biodiversity to a whole new level! Ecology scholars use data to calculate three different diversity indices based on the organisms in the Gorongosa National Park. The four-part activity uses an...

Explore the strengths and weaknesses of box-and-whisker data display. An interactive lesson asks learners to create a box-and-whisker plot from a set of data. Challenge questions focus on determining what types of conclusions they can...

Interpreting graphs is an essential skill for young scientists. An interactive online lesson gives individuals an opportunity to review the components of a graph and learn to read and interpret the shape of a graph. The lesson includes...

A change in a parameter can end in overpopulation. The resources gives pupils the opportunity to control the parameters of rabbits and wolves in a natural setting. Using the set parameters, the simulation runs and displays the population...

The plot thickens to get a functional understanding. After a short review of plotting points on the coordinate plane, class members learn the difference between functions and relations in the second lesson in a series of nine. They...

Finding a balance between too much protein and not enough doesn't have to be a guessing game. Young scientists use an interactive lesson to learn how to calculate protein content in cattle feed and how to mix feed to create the ideal...

Estimate and explore the length and weight of classroom items using standard measurement and scales. Students will work in groups to determine appropriate measuring tools, weigh or measure items, and record their results on a data chart....

Will human population growth always be exponential, or will we find a limiting factor we can't avoid? Young scientists learn about both exponential and logistic growth models in various animal populations. They use case studies to...

Fifth graders identify and classify scalene, equilateral, and isosceles triangles. In this triangle lesson, 5th graders define the different attributes of 3 types of triangles and sort them by descriptions and...

Study velocity while examining graphical representations. As scholars work with the animation, they discover the effect the height of an incline has on the velocity of the biker. They make conclusions about the slope of the...

Students explore differents types of triangles and quadriaterals. In this polygon instructional activity, students  model identify and compare two and three dimensional geometric figures. Students create tangrams and discover the...

Learners classify triangles and make connections regarding angle measurements and attributes of acute, right, and obtuse triangles. They listen to teacher define and explain triangles. Everyone imagines a place where a broken wing for a...

First graders identify different types of transportation, and explain why each is important. They pretend they are going on a trip. They choose their mode of transportation, and use play money to buy their tickets.

Second graders collect data on different forms of transportation and create a bar graph or pictograph with the information.

Pupils graph data of sports figure running time using x-axis y-axis to find slope of trend line, mathematically find the interpolated and extrapolated values for data points. Using the information they make predictions.

Second graders participate in a series of hands-on, online and multimedia activities that examine the concept of area. They view clips from the animated series Math Monsters and discuss the purpose of area and how it is used in the real...

Second graders view clips from the animated series Math Monsters, and discuss the many ways patterns can be found in the world around us. Following the video portion of the lesson, 2nd graders visit a variety of Web sites to assess their...

Learners investigate spheres through sketches. In this geometry lesson, students sketch two and three dimensional shapes creating nets. They find and differentiate between the nets for prisms, pyramids, cones, cylinders and spheres.

Young scholars perform transformation on trig functions. In this precalculus lesson, students relate the London Eye observation wheel to trig function. They use a TI navigator to visualise the parameter created by this view and relate it...

A reference guide to obtuse triangles. It provides a definition and interactive animated activity that enhances further explanation.

An introduction to a type of three-dimensional shape called a polyhedron. See examples and play with an interactive animation, showing the faces, vertices, and edges of pyramids, which are a type of polyhedron.

Learn about platonic solids, a special type of polyhedra. Read a definition, make three-dimensional models using printouts, and play with an interactive animation, which will show you the faces, vertices, and edges on platonic solids:...

A complete reference guide to types of triangles and triangle perimeter and area. It provides definitions and interactive animated activities that enhance further explanation.
