CLARK — Students in Ms. Veiksans and Miss Bartolomeo’s science classes at the Carl H. Kumpf School in Clark are learning about different types of chemical bonds. The students conducted a lab experiment to identify whether various compounds are ionically or covalently bonded. The students used different substances such as salt, sugar, and baking soda. They used testers to assess the conductivity of each of the substances. After the students observed the substance’s conductivity, the students used their data and prior knowledge on properties of bonding to come to conclusions.
