22 Science Fair Project Ideas for High School Students
22 science fair project ideas for high school students, grouped by field, with the question, materials, level, time, data and approval rules for each.
How the VEX Robotics Competition (V5RC) works in 2026-27: Override match rules, registering on VEX Events, judging and how to win.
The VEX Robotics Competition, now officially the VEX V5 Robotics Competition (V5RC), is a team robotics contest for grades 6 to 12. The 2026-27 game is called Override.
You win matches with a reliable robot and a practiced driver, and you win judged awards with your engineering notebook and team interview. If you'd rather enter a research project than a robot, see our list of science fairs and competitions for high school students.
Facts checked October 2026. For 2026-27, VEX Robotics and the REC Foundation run separate competitions. Everything below covers VEX's V5RC season, the one that leads to the VEX Robotics World Championship.
V5RC is a robotics contest from VEX Robotics, the company that makes the parts. Teams of students design, build and code a robot for a new game each season, then play it at local tournaments. The best teams advance through Regional Championships and Signature Events to the World Championship.
In Override, robots place Pins and Cups in Goals and set Toggles to their alliance's color. When the match ends, the alliance with more robots in the Midfield owns the yellow Pins placed there. Every robot must fit inside an 18-inch cube at the start of a match, under rule SG1.
Younger students play the VEX IQ Robotics Competition (VIQRC), for grades 4 to 8. Its 2026-27 game, Level Up, uses 60-second matches in which two robots work together to score.
VEX Robotics and the REC Foundation now run separate competitions. VEX's competition pathway page calls VEX Events the only authorized platform for VEX Robotics competitions and the exclusive path to the 2027 World Championship. The REC Foundation runs its own contest, RECF Robotics, and says its events won't qualify teams for that championship.
The REC Foundation announced a more independent approach on May 10, 2026. RobotEvents.com now shows only a notice about the change, with links to both organizations.
If your team registered on RECFEvents.org, you're in RECF's contest, whose events lead to the 2027 RECF STEM World Championship in St. Louis.
A V5RC match lasts 2 minutes: a 15-second autonomous period, when robots run only on code, then 1 minute 45 seconds of driver control. Robot Skills runs are separate 60-second matches that one team plays alone, either driver-controlled or autonomous, per the 2026-27 game manual.
The alliance ahead when autonomous ends gets the Autonomous Bonus. An alliance that completes a set list of autonomous tasks earns an Autonomous Win Point, which counts toward its ranking.
Each team plays at least six qualification matches per event. Rankings from those matches set the order for alliance selection, and the chosen alliances play the elimination rounds.
V5RC suits students who like building, coding or driving and can stay with one team from the summer build to spring championships. It works best if your school has a team, a coach and a room to build in. It's a harder fit if your weekends are already full from fall to spring.
If your team would rather build something that flies, see our guide to aerospace competitions for high school students. For contests with no entry fee, see our list of free competitions for high school students.
Most students join a school or club team that already exists. If your school has none, find an adult coach and register the team on VEX Events to get a team number.
Judged awards, such as the Excellence and Innovate awards, are decided from your team interview, your engineering notebook and what judges see at the event. A team can win only one judged award per event, according to VEX's judge training course.
The notebook is your team's record of the season: the problem you saw, the ideas you weighed and what happened when you tried them. VEX's notebook training for judges says judges read for that thinking. It lists a mechanism that jammed and a strategy a team dropped as entries worth reading.
Judges come to your pit, and every team must get the chance to be interviewed, per VEX's interview training. They ask how and why you built what you did, and the rubric expects students to explain their own work. If you submit a Season Summary, judges read it before they reach your pit.
For 2026-27, the Innovate Award needs no separate form, per the judging Q&A.
In our Nova Competition Mentorship, you work one-on-one with a mentor on your competition materials and practice presenting to judges.
Give every job an owner, get a simple robot driving early and spend more meetings testing than redesigning. Practice autonomous and driving until both work every time.
The 2026-27 manual expects every team to have drive team members, coders, designers and builders, while notebookers and strategists are optional. Each student can belong to only one team per season. On a small team, people cover two roles each.
VEX released Override at the 2026 World Championship, and the season runs until the next one in April. A team that starts in late spring can use the year like this.
If your team has a gap between events, pick a small build from our robotics and drone project ideas.
Change one value at a time, such as a turn speed or a drive distance, and run the routine five times after each change. Use sensors, such as motor encoders and an inertial sensor, instead of timed moves, so the robot measures where it is. Start from a spot marked with tape, and log every run in the notebook, including the failures.
Code in VEXcode, VEX's coding software, which offers blocks, Python and C++.
Watch for five habits: overbuilding early, keeping the notebook late, skipping skills runs, missing rule updates and using AI without credit. Here is what to do instead.
VRC stands for VEX Robotics Competition. VEX now calls it V5RC, after the V5 robot system teams build with.
For 2026-27, registered VEX IQ and V5 teams can submit VEXcode VR scores from September 3, 2026 to February 1, 2027. The top V5 middle school team and the top V5 high school team each earn a World Championship spot, per VEX's entry guide.
No. You can learn during the season, starting with simple drive commands in blocks. The manual expects every team to have at least one coder, so if nobody wants the job, take it.
