Ninth graders graph linear functions using coordinate points. In this algebra activity, 9th graders plot points and graph a line. They use the slope intercept form to graph their equation and evaluate points as solution to the function.

Young scholars explore story structure. In this story structure literacy lesson, students listen to the story Ruby's Wish by Shirin Yim Bridges, stopping at points to identify a problem and predict possible solutions which are then...

Students observe that movement of a solute in the solvent increases the rate of dissolution. They demonstrate that when the solute is broken into smaller pieces it dissolves faster.

Pupils identify diffusion and its processes through experimentation and calculations. They also use a CBL and conductivity probe to measure the conductivity of various solutions and study the effect of concentration gradients on the rate...
