Exploring the Dissolution of Powdered Lemonade: A Scientific Investigation

This project investigates how temperature affects the dissolving rate of powdered lemonade in water. By utilizing the five senses, students will make observations, design a hypothesis, and conduct controlled experiments. The procedure is designed to be child-friendly so that even a six-year-old can follow the steps easily. Participants will analyze and document their findings to draw conclusions about their hypothesis, ultimately communicating the results of their investigation into the relationship between temperature and dissolution rates in a clear, organized manner.

Presentation Transcript

  1. Make an OBSERVATION • What are the 5 senses? • An observation is something you notice from using one of the 5 senses. • Example: Sally notices that her powdered lemonade dissolves quickly.

  2. Create a QUESTION. • Example: • Does the temperature of the water affect how fast the lemonade will dissolve?

  3. State your HYPOTHESIS (educated guess) • I think that powdered lemonade dissolves faster in warm water than cold water.

  4. PLAN your PROCEDURE • What materials will you need? List all of them. -Cups -Spoons -Powdered lemonade -? -? • Write out the steps you plan to follow. If a 6 year old can understand your directions, then you’ve written them well. Step 1-Put one tablespoon of lemonade in a cup. Step 2-Add water that has a temperature of 50 degrees F. Step 3-Stir. Step 4-?

  5. CONDUCT controlled EXPERIMENT • Perform the steps • Write down all of your observations and data. • There is an old scientist saying- ”If you didn’t write it down, then it didn’t happen.”

  6. ANALYZE results • Look at the data you collected. When you did the experiment, what happened? What did you see, hear, smell, etc.? • Organize it (table, chart, graph). • Discuss your findings with other scientists.

  7. Make CONCLUSIONS • Write a statement that states if your hypothesis was correct or not. • Example: Based on my data, my hypothesis was correct.

  8. COMMUNICATE Results • I learned that as the temperature of the water increased, the amount of stirs needed to dissolve the lemonade decreased.
