In this science project, you will get to make your own homemade bath bombs and explore how changing the amounts of the different ingredients affects the fizziness of the bath bombs when you toss them in the bath.
31 Μαΐ 2023 · Explore how water temperature affects the eruption and fizz of homemade bath bombs in this fascinating bath bomb science fair project.
15 Αυγ 2017 · Record your results in your lab notebook. For example, if the bath bombs in the three trials using your normal recipe dissolved after 95 sec, 80 sec, and 100 sec, the average time to dissolve would be 92 sec for the normal recipe (since 95 sec + 80 sec + 100 sec = 275 sec, and 275 sec ÷ 3 = 92 sec).
This experiment focuses on how materials change when they react together. First watch the ‘bath bombs’ demonstration video, then find out how your learners can use similar ingredients to explore an irreversible reaction.
We will be: Investigating the science behind bath bombs. Learning objectives. Understanding. I can describe how some materials produce new materials when they are mixed. I know that this is an irreversible chemical reaction. Enquiry skills. I can make careful measurements and observations. I can record data and results. I can make predictions.
Background science. Learners are likely to have eaten fizzy foods (sherbet), drunk fizzy drinks and be aware of fizzy bath bombs. This investigation will explain the science behind the ‘fizzing’. Acids and alkalis are chemicals that react together to form new materials.
Have you ever had a refreshing bath using a bath bomb? A bath bomb is several ingredients mixed and molded into a shape, which becomes fizzy when it touches the water. It can be quite a relaxing experience, especially if your bath bomb has a nice fragrance or includes some bath salts.
