Science Lab aligned to the 5th Grade Utah Benchmark:
The weight of an object is always equal to the sum of its parts, regardless of how it is assembled. In a chemical reaction or physical change matter is neither created nor destroyed. When two or more materials are combined, either a chemical reaction or physical change may occur. Chemical reactions are often indicated when materials give off heat or cool as they take in heat, give off light, give off gas, or change colors. In a chemical reaction, materials are changed into new substances. In a physical change a new substance is not formed.
This science lab consists of 3 experiments that involve finding the mass or weight of the individual parts and the whole before and after experimentation.
The experiments follow the scientific method and require students to form a hypothesis (sentence frame provided) and write conclusions (sentence frame provided).
The three experiments involve a phase change, manipulating an object, and a chemical change (baking soda and vinegar).
Required materials include:
empty water bottles
