Ninth graders solve multi-step equations.  In this Algebra I lesson, watch a video on solving equations with variables on both sides of the equal sign.  Students visit an Internet site to solve simple equations through the use...

Learners use the on-line affine recurrence plotter to graph equations. They work on-line to create graphs of trout in a trout pond and savings account balances when interest is compounded over time. Links to the four one-day lessons are...

Learners rewrite word problems using equations. In this algebra lesson, students relate the concept of equations and symbols to the real world. They graph their solutions on a graph and analyze it.

Students explore the general form of the sine equation.  In this trigonometry instructional activity, students explore the relationship between the changing parameters and the graph of the sine equation.  Students use data and...

Young scholars observe how math is important in navigation and engineering. They study how surveyors use math and science to calcute, count, measure, label, and indicate distances on a map. They estimate specific distances.

Students use an on line website to simulate the effects of light intensity and wavelength on photosynthesis. In this photosynthesis lesson plan, students determine how wavelength of light and intensity of light affect the rate at which...

Students conduct an experiment to observe oxidation. In this chemistry lesson, students explain how rusting happens. They rank metals according to their conductivity.

Students observe the rusting process in the lab. For this chemistry lesson, students rank metals according to their conductivity. They give real world applications of this activity.

Students explore the concept of graphing data. In this graphing data activity, students determine the percentage of sugar in bubble gum. Students graph type of gum vs. sugar percentage. Students create a table of their data.

Students observe and record the corrosive nature of oxidation-reduction reactions, and determine the electro-chemical series of selected metals.

Students view a video about the formation of precipitates. They complete a worksheet that asks them to identify what makes a compound form and what holds it together.
