UTeach Outreach applies inquiry-based strategies to help the students in the discovery process.

Lesson 1: Today we discussed the topic of density and how we can use density in order to identify unknow material. The students used the PhET simulation to play with virtual objects and manipulate physical properties like volume and mass. Afterwards the students completed a work sheet that applied what they had learned. Overall it was a great day for our young scientists!

Lesson 2:  In lesson 2 our young scientists investigated the difference between a physical change and a chemical change. We performed experiments like adding baking soda to vinigar and observing a chemical change take place. We also discusssed how eating pop rocks is actually a physical change and not a chemical change.

Lesson 3: For our third lesson we discussed what potential and kinetic energy is and what they depend on. The students conducted experiments using a ramp and a miniature skateboard to investigate how potential energy can affect kinetic energy. We also used a computer simulation that shows as kinetic energy increases, potential energy decreases. Then we discussed how water slides work by eliminating friction!
 
Lesson 4: We discussed the pH scale and what kind of household items are acidic and basic (like vinegar and Windex). The students had the opportunity to investigate what makes milk curdle. They were able to form a hypothesis and procedure and conduct the experiment. We then discussed their results and concluded that acids make milk curdle. 
 
Lesson 5: In this lesson, we discussed how solar panels convert solar every into electrical energy. We prepared our own solar cells using titanium dioxide and acetic acid. Once we prepared our solar cells, Maria and I took them back to UT to bake the solution into the glass. We will continue this expedient next week!
 
Lesson 6: In this lesson, we completed our solar cells that we started last week. The students used graphite from their pencils and an electrolyte solution to aid in converting light energy to electricity. To complete the solar cells, some groups added blackberry juice, blueberry juice, or a mixture of both. We then used a multimeter to measure the voltage created by different types of lights (low light, room light, heat lamp). We then compared the voltages from the cells with different types of juice. We found that solar cells with blackberry juice created the most voltage. 
 
Lesson 7: For our last class day, we played Jeopardy, where the topics covered all of the material from our past lessons. Afterwards, we played "trash-sketball", where teams of 4-6 students answered questions for points, upon answering a question correctly, the student would toss a ball into a trashcan across the classroom, if they made the shot, it meant extra points for that team! This last class day showed how exiting STEM club has been!
