Students evaluate the importance of hormones in living things. In this biology instructional activity, students experiment on carrots to differentiate how humans and plants reproduce. They collect data from experiment to answer analysis...

Students use Curveball to complete the activity to determine how the speed of airstreams changes in relation to changes in the distance of the airstream from the center of the baseball.

Young scholars read an explanation from a NASA Web-based textbook, then demonstrate an understanding of the text by using it, along with FoilSim, to complete an activity that manipulates the lift coefficient equation.

Students evaluate the notion of aging by reviewing some of the studies that occurred on John Glenn's space shuttle mission.

Learners experiment with enzymes as key components of chemical reactions in all living things through this series of lessons.

Young scholars conduct a simple investigation to explore tooth decay.

Students collaborate with another classroom via the Internet to share data, questions, results, and check the validity of their testing procedures.

Students explore the characteristics of invertebrates in their backyards. They observe, describe, and classify specimens. They conclude with a "snail race."

Looking for authentic hands-on nutritional experiments? High schoolers will perform experiments to test for the presence of vitamin C in several solutions as well as the effect of caffeine on Daphnia. They will also consider the...

Examine parts of an expression in this algebra lesson. Ninth graders identify the properties of the coefficient and their behavior to the graph. They graph the equation on a TI to see their results.

Learners design an investigation using yeast. In this environmental engineering instructional activity, students design an investigation to determine how environmental factors affect the growth of yeast. They will collect quantitative...

When going for distance, does it make a difference at what angle you launch the rocket? Teams of three launch foam rockets, varying the launch angle and determining how far they flew. After conducting the series of flights three times,...

How high did the ball go? Engineering teams build a working pneumatic system that launches a ball into the air. The teams vary the amount of pressure and determine the accompanying height of the ball. An extension of building a device to...

Through exploration of linear programming through graphs and equations of inequalities, young scholars relate linear programming to real life scenarios, such as business. Graphing and shading is also part of this exercise.

Algebra learners look at equivalent expressions in the context of three different operations: division, squaring, and absolute value.  In comparing these values, they will identity when expressions are equivalent. 

As an introduction to the hypothesis and testing method of investigation, young history detectives engage in a special investigation of a family artifact. After watching a short video that demonstrates the method, they develop a...

Using elimination to find the point of intersection of two lines, students learn to solve systems of equation. They graph their solutions and use the TI to verify the solution.

Students will use scientific reasoning to formulate ideas about the formation of the universe using the Big Bang Theory. The use of critical thinking skills is part of the activity and the foundation of the scientific method will serve...

Pupils explore financial applications of linear functions. As they investigate the steps necessary to plan a fundraising event, learners explore minimizing cost and maximizing profits.

Learners explore area of polygons and regular polygons in this math lesson. They calculate the area of several polygons using Cabri Jr. and analyze shapes and write formulas to solve for the area.

Students solve problems using the TI. In this calculus lesson, students evaluate functions using sequences. They graph the functions on the TI and make observations.

Young scholars solve problems using distribution. In this algebra lesson, students factor equations using the distributive property. They graph their solution on a graph.

Learn how to calculate the length and midsegments of triangles. Learners differentiate between similar and congruent triangles. They create a spreadsheet with their findings.

Students engage in a lesson that gives them the tools needed to become knowledgeable credit consumers. The companion website for the ITV program TV-411 is used to provide learners with an interactive experience of what credit has to offer.
