Watch UT engineering students demo the activities from the Equal Opportunity in Engineering Program's (EOE) World of Engineering then try them yourself!
Recommended Grades: All
Activity #1: Apple Oxidation
- Students will practice making a hypothesis.
- Students will observe the oxidation process.
5 Ziploc bags, apple, water, lemon juice, vinegar, milk, knife (for adult use), cutting board, permanent marker
- Gather your materials
- On 4 Ziploc bags, write the name of the liquid you’re going to test. Label a fifth bag “nothing” for your control bag. This bag will contain apples with no liquid. That way, you’ll be able to see the difference between a normal apple and the other apples that have been soaked!
- Pour the water, lemon juice, vinegar, and milk in separate bags. Make sure to match each liquid to its label.
- Place two apple slices in each bag. Seal the bag and lightly shake it so the liquid coats the apple slices. Let them soak for two or three minutes.
- Pour any excess liquid out of the bags. Reseal them and check on the apples every 10 to 15 minutes to see what happens.

Activity #2: Balloon Rocket
Students learn about Newton’s Law of Motion and how the forces make an object move.
Materials: 1 balloon, 1 long piece of string, 1 plastic straw, tape
- Tie one end of the string to a chair, doorknob, or other support
- Put the other end of the string through the straw
- Pull the string tight and tie it to another support in the room
- Blow up the balloon (but don’t tie it). Pinch the end of the balloon and tape the balloon to the straw. You’re ready to launch.
- Let go and watch the rocket fly!

EOE aims to provide equal and equitable opportunities for underrepresented ethnic minorities and students with marginalized identities by:
- Increasing awareness of engineering to diverse pre-college students
- Promoting excellence in academics to increase retention and graduation
- Developing leadership and professionalism for success in a global workforce
To cultivate an inclusive network at the Cockrell School of Engineering that reflects the diversity of the population within the state of Texas.
The Equal Opportunity in Engineering (EOE) Program provides many opportunities for underrepresented minority students through our 4 program areas: Outreach & Recruitment, Academic Initiatives, Leadership & Professional Development, and Research & Graduate Opportunities.
