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

Lesson 1: Today we talked about mass, matter, density, and volume. We worked on a density simulation by finding the density, volume, and mass of blocks in the Phet science simulation. We also demonstrated density with a golf ball and a ping pong ball. To finish up the meeting we worked on a review of what we learned today.

Lesson 2: Today in our STEM meeting we did chemical changes and physical change. We did a demonstration with paper. Then we did a chemical experiment with baking soda, vinegar, pop rocks, hydrogren peroxide, red food dye, and a slice of potato. We tested these substances together and found out if it was a chemical change or physical change.

Lesson 3: We learned about potential and kinetic energy and the less friction you got the faster you will go. Also that as potential energy falls, kinetic energy rises. We demonstrated this by using a simulation. And we did a hands on activity with skateboards and that showed us an example of friction. 

Lesson 4: Today we studied pH and tested the pH of curdled milk. To test the pH, we used pH paper and the materials we used were pipet, vinegar, ammonia, cups, and baking soda solution. Then we talked about our data and made a conclusion. 

Lesson 5: We poured titanium dioxide and vinegar into mortar and pestle and made it into a fine powder. We used the multi meter to test the resistance of the glass it turned out to be. We also used a pipet to pour it onto glass and spread it out with a straw.

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: Today we played jeopardy and trashketball. These games helped us review each of the experiments we had done in the weeks before. We competed against each other to see who would win. We had fun and prepared for our competition at UT.
