The Car with a Lot of Potential
Read the Fine Print
Educational Use
Rating
0.0 stars

Working in teams of three, students perform quantitative observational experiments on the motion of LEGO MINDSTORMS(TM) NXT robotic vehicles powered by the stored potential energy of rubber bands. They experiment with different vehicle modifications (such as wheel type, payload, rubber band type and lubrication) and monitor the effects on vehicle performance. The main point of the activity, however, is for students to understand that through the manipulation of mechanics, a rubber band can be used in a rather non-traditional configuration to power a vehicle. In addition, this activity reinforces the idea that elastic energy can be stored as potential energy.

Why do atoms react with some elements but not others, and why do they form compounds with such different properties? One of the reasons is the bonds that they form. This pathway provides resources relating to the reasons that atoms bond, and the three different types of bonds that form between atoms: covalent, ionic and metallic.

Chemical reactions are the foundation of chemistry, and understanding how elements combine and in what ratios helps us to understand the world around us. This pathway provides resources about how different chemicals react, and the ratios in which they react, a field of study known as Stoichiometry (literally: element measuring).

0.0 stars

In this activity, students explore reactions in which chemical bonds are formed and broken. Students experiment with changing the temperature and the concentration of the atoms in order to see how these affect reaction rates. They also learn how to communicate what happens during a chemical reaction by writing the ratios of reactants and products, known as stoichiometry.

Chemical bonds are the glue that hold molecules together. We will learn about the different kinds of bonds, ways chemists draw bonds and molecules, and how the type of chemical bonding affects the bulk properties of a material. We will cover electronegativity, Lewis dot structures, VSEPR, bond hybridization, and ionic, covalent, and metallic bonds.
