Experiment⭐ 30 XPThe Engineering Design Process (Part 2)
Data and Evidence.
🎯 Your mission
Predict it first. Then prove yourself right (or wrong).
⚡ The twist
Nature loves to surprise the careful watcher.
Mind = Blown
🔬 The more you look, the more nature shows you.
Make a hypothesis first
Before you start: write down what you think will happen, and why.
What You'll Learn
Engineers use the design process to solve problems: identify the problem, research, brainstorm solutions, build a prototype, test it, evaluate results, and improve the design.
Key Words
- control
- data
- observation
Materials Needed
- cups
- aluminum foil
- ruler
- markers
- popsicle sticks
Safety First
- Handle glass items carefully to avoid breakage.
- Do not mix unknown chemicals together.
- Tie back long hair before starting the experiment.
Steps
Study the diagram and label the parts you recognize.
Create a solar oven from a pizza box lined with foil. Measure the temperature inside on a sunny day. Try melting chocolate or cheese.
Draw a detailed diagram of what you observe.
Write a conclusion: what did your results show? Did they match your prediction?
