Hi, I'm presenting my science fair project on conserving water in our school garden, which matters a lot during Texas droughts. My main claim is that using soil-moisture sensors to guide watering can reduce water use while keeping plants healthy. First, I identified the problem: some plots were overwatered and others were drying out. Then I set up three beds—tomatoes, peppers, and herbs—with identical drip lines. I installed moisture sensors in each bed and logged readings three times a day for four weeks. I created target moisture ranges based on the soil's feel test and extension guides, and I only watered when a bed dropped below its target range. I recorded water usage with simple inline gauges and tracked plant growth by weekly height measurements and leaf-color ratings. Results showed that the sensor-guided beds used about 20% less water than our usual schedule and had fewer wilted afternoons. The tomato bed especially benefited because it stayed within the target range more consistently. I also noticed that cloudy days meant less watering the next morning. My conclusion is that a threshold-based plan can save water and support plant health. For next steps, I want to test how the targets should change in hotter months and possibly build a simple alert that pings when a bed drops too low.

Today I'm giving a book report on a realistic novel about a seventh grader who moves with her family to the Texas Hill Country. My main claim is that the author shows how belonging is built through small, consistent acts of care. First, after a spring storm damages fences, the narrator helps neighbors gather loose boards and check on goats. These scenes reveal that service leads to new friendships. Second, the setting acts like a partner in her growth. The recurring image of bluebonnets starts as something she thinks is just a postcard cliché, but it later becomes a sign of resilience when flowers return after the hail. Third, the first-person point of view lets us hear her doubts. She worries her city habits won't fit in, but as she volunteers at a community clean-up, her inner voice shifts from fear to pride. Finally, the story's structure—storm, clean-up, and a final picnic—mirrors how communities recover together. In conclusion, the novel argues that belonging isn't instant; it's built by showing up for others and letting a place's rhythms teach you how to be part of it.

Hi, my historical research explores how Juneteenth began in Galveston, Texas, and why remembering it matters today. My main claim is that Juneteenth represents both delayed freedom and community-built celebration that continues to shape civic life. First, I explain the timeline: the Emancipation Proclamation took effect in 1863, but enforcement reached Texas in 1865, when General Order No. 3 was announced in Galveston on June 19. Second, I examined how people celebrated in the years that followed—church services, parades, music, and shared meals—which turned the date into an annual marker of freedom and hope. Third, I looked at its modern evolution: community festivals, museum exhibits, and its recognition as a federal holiday, which signal how public memory can grow. I also used local sources like historical newspapers, church bulletins, and a recorded oral history to learn how newly freed people navigated work, family reunions, and schooling. A limitation of my study is that some sources are incomplete or biased, so I compared multiple accounts to reduce gaps. Overall, Juneteenth shows that freedom is not just a moment but a practice communities keep alive through tradition and education.

Good afternoon. I analyzed our team's Friday night football games to see which offensive choices help us move the chains. My claim is that we gain more first downs when we lean on outside zone runs early and then switch to play-action passes once safeties creep up. First, across six games, drives that started with two or three successful outside runs averaged more yards per play than drives that opened with low-percentage deep shots. Second, when defenses brought extra players near the line, play-action slants and quick outs produced chunk gains and fewer risky throws. Third, turnovers dropped on drives where the run-pass mix stayed balanced and we avoided obvious passing downs. I also looked at context: against teams with strong interior linemen, bouncing runs to the edge worked better; in windy games, shorter passes outperformed deep balls. Based on this, I recommend a script that tests edge runs on the first series and then layers in play-action if safeties step forward. I'd like to add more data on defensive fronts and motion looks to confirm the pattern against tougher opponents.

Hi, I'm Maya, and for my science fair project I compared so-called biodegradable plastic bags to regular grocery bags in a backyard compost setup. My main point is that some biodegradable plastics do break down faster, but the conditions matter. First, why this matters: plastic trash adds up quickly at school and at home, and labels can be confusing. Second, how I tested: I used four 10-gallon bins with the same mix of leaves and food scraps. I cut standardized strips from each type of bag, recorded their starting mass, buried them, and checked them weekly for eight weeks. I measured mass loss, took photos, and logged temperature and moisture. Third, the results: the biodegradable strips lost an average of about 42% of their mass, while conventional plastic lost around 2%. The biodegradable pieces felt crumbly at the end and there was a slight vinegar smell from the PLA items. I also saw more variation after a cool, rainy week, which likely slowed decomposition. Fourth, limits and next steps: backyard compost isn't as hot as industrial composting, and not all products labeled biodegradable are the same. I want to test utensils and trays like the ones in our cafeteria and try a tumbler bin that keeps heat steady. If utensils also break down quickly, our school could switch supplies and cut lunch trash by at least one bag per table per day.

Hello, I'm Jordan, and this is my book talk on Hatchet by Gary Paulsen. My claim is that the novel shows how resilience grows through problem-solving. Quick plot: thirteen-year-old Brian is the only survivor when a small plane crashes in the Canadian wilderness, and he must learn to find food, build shelter, and signal for help. Key point one: Brian fails and learns. For example, his first fire attempt fizzles, but after noticing sparks from his hatchet, he uses birch bark for tinder and finally succeeds. Key point two: Paulsen's craft puts us inside Brian's head with close third-person narration and short, choppy sentences during emergencies to mirror panic. Key point three: The setting shapes the character. The lake provides fish but also mosquitoes and a moose attack, forcing Brian to adapt. By the end, Brian changes from waiting to be rescued to acting with a plan, which supports the theme. This matters because it suggests that staying observant and breaking big problems into steps can help in real-life emergencies, like power outages or getting lost on a hike.

Hi, I'm Sofia. My historical research looked at the Texas cattle drives after the Civil War, especially the Chisholm Trail. My thesis is that the drives linked cheap Texas longhorns to high-demand northern markets, reshaping small towns and setting traditions that still show up in Texas culture today. First, the economics: after the war, Texas had millions of cattle worth a few dollars each in-state, but prices were many times higher near railroads in Kansas. That price gap motivated long drives. Second, logistics: trail bosses hired crews to move herds north for months, crossing rivers and avoiding stampedes, then loaded cattle onto trains in places like Abilene. Third, impacts: towns along the routes grew as supply hubs; at the same time, the open range shrank as barbed wire spread and rail lines expanded, which limited routes and displaced Native peoples who depended on the plains. Finally, legacy: skills from the trail—roping, riding, and herd management—evolved into rodeo events and stock shows you still see at big Texas venues. I used maps, diary excerpts from a trail boss, and shipping data to support these points.

Hey everyone, I'm DeAndre, and I analyzed how Texas early-season Friday Night Football games in high heat affect hydration, cramps, and missed plays, and what teams can do about it. My main claim is that structured cooling and hydration plans can cut cramp-related stoppages without slowing the game. Method: I watched five varsity games in August and September, noting heat index from kickoff to halftime, visible cramp incidents, and whether teams used shade canopies, cool towels, or timed water breaks. I also looked at public box scores for substitutions. Results: in games with mid-90s heat index, teams with shade plus timed breaks averaged about a third fewer cramp stoppages than teams with only standard timeouts. One game showed almost no cramps after halftime when coaches added a cooling station. Limitations: small sample size and different roster depths could affect results. Mechanism: high heat increases sweat and electrolyte loss, which raises cramp risk. Recommendation: try a two-week pilot at our school with pre-hydration reminders, a shade canopy, and cooling towels, then compare cramp counts and missed snaps to previous games.
