Failed experiment


Investigating catalysts. The student was so slow in lighting the spill the experiment was over before he was ready - we had to do it again after this.

Ionic Shapes


 We used a Brother Scan'n'Cut machine to cut out 1+, 2+ and 3+  ions along with the 2- and 1- counterparts. The students seem to find it easier to create and write down chemical formulae.

Momentum



The @pascoscientific Smart carts excel at momentum equations. Even with quickly done student data the students can determine the relationships between mass and velocity in collisions
