This is an interesting problem that approaches higher-degree polynomials from a different perspective. Given a third-degree polynomial, two known zeros, and a y-intercept, find the value of the polynomialÕs coefficients. This problem...

Take a look in the window. Pupils watch a presentation to discover how to graph a polynomial using a graphing calculator and using the window to find the extrema. Scholars use their knowledge from previous lessons to gain a rough idea of...

Provide a sketch of the suspect. Scholars see how to use the key aspects they know about polynomials to create a sketch of the graph. Learners factor to calculate the zeros by factoring, find the end behavior, and determine the...

Root for those learning about roots. An installment of an extensive playlist covering derivatives focuses on using linear approximations to estimate roots. The example problem shows how to find the fourth root of 15 without a calculator.

Viewers of a short video learn about salt and water molecules and how their characteristics determine how they interact with each other. Then, they watch a simulation of how the interaction limits the uptake of water in plant roots and...

Ninety-nine percent of the water absorbed in plants transpires into the atmosphere. The second video in a three-part series explains transpiration in plants. It details how they pull water into the roots; how water passes through the...

Trees need nutrients, so how does a jungle grow on top of a desert? The video walks through one such jungle. The root mat and soil samples appear unique. It discusses each discovery and conclusion throughout the virtual tour. The video...

Build a connection between the equation and graph of a quadratic function. A thorough video lesson demonstrates how to use find the roots and y-intercept of a quadratic function and create a graph from the three points. The instructor...

The inflection point, the point where the second derivative is zero, is the focus of a video  that works through a problem where it is not obvious to see the roots of a function. The solution to the problem requires using...

Discuss what nutrients plants require and where they get them from. An informative video explains the dermal, vascular, and ground tissue in both monocot and dicot roots, as well as stems and leaves. 

Non-vascular plants, like moss, are able to survive on photosynthesis. A video explains plant structure for both vascular and non-vascular plants. It includes the parts of each plant and adaptations to various environments such as...

Get to the root of the problem with an instructive lesson! Learners find the roots of a function using the quadratic formula. A video shows the process and includes an explanation of the substitution steps. 

How do plants get the nutrients they need? This is the focus of a video that discusses how plants use photosynthesis to survive, with or without dirt.

The classic carnation color-change activity for demonstrating water transport up a plant stem is played out in this video. Add the clip to a PowerPoint presentation or show it when teaching plant structure to young botanists. If you have...

Find the zeros on a given graph of a quadratic equation. What does this mean? It means to find the values at which the parabola crosses the x-axis. It seems pretty straightforward to be able to look at a graph and identify the points at...

Viewers os this short video learn how to prove that a root exists in a given interval without having to determine the actual value of the root. Applying the Intermediate Value Theorem is most helpful in this situation.

Uncover the connection between continuity and roots between a given interval with a video that explains how to approach a problem that asks if roots exist between a given interval. The instructor shows how to test the interval...

Discover some more applications of the Intermediate Value Theorem with a video that shows how to prove that an equation has at least one real solution. Viewers learn to consider domain and range to identify an appropriate interval to use...

A right triangle. Two given measurements for two side lengths and one unknown length. Use the Pythagorean theorem to solve this problem and find the missing value. Squares and square roots are used in this problem and don't worry when...

The classic carnation color-change activity for demonstrating water transport up a plant stem is played out in this video. Add the clip to a PowerPoint presentation or show it when teaching plant structure to young botanists. If you have...

In this lesson, students are shown the relationship between roots and fractional exponents (one can be rewritten as the other). It is 2 of 10 in the series titled "Roots and Fractional Exponents."
