Students will learn about acids and bases through a class discussion and then test a dilute acid and dilute base with neutral litmus paper to learn how the paper indicates something is acidic or basic. Once that skill is learned they can move on to test some common items that would be found around their house to determine if they are acids or bases. Optional: Extra litmus paper is included to test more items either from home or around the school building for a greater understanding of acids and bases. The activity contains enough materials for 6 groups of students.
Bacteria are often associated with various diseases, infections, and other sicknesses. Certain bacteria can have negative effects on other living organisms, but in reality the vast majority of bacteria range from harmless to incredibly beneficial. This kit contains materials for students to use in investigating bacteria in their environment. While learning proper microbiological techniques, you will test hands, mouths, and your classroom for bacteria, before and after cleaning.
Kit Includes: 2 x 200mL Nutrient Agar 20 Sterile Petri Dishes 20 Sterile Cotton Swabs
