https://www.tobinscience.com/webquest-hs-chem.htmlHow it works
Your teacher gives you the webquest sheet (paper or digital). Every answer goes on it.
Each stop opens in a new tab. Use the sliders and buttons on that page — your answers come from what you see.
Close the tab, tick Done, and open the next stop. Finished early with a partner? Play the bonus.
Stops
Chemistry Unit Intro
Read the hook, pick a big question, play two activities.
Simple Science Videos: Bonding and Naming
Watch three one-minute videos and fill in the blanks.
Vocabulary
Flip the Word Wall cards and define 15 words in your own words.
Chemistry Part A: Bonding and Ionic Formulas
Bond atoms on screen, then run the criss-cross machine.
Chemistry Part B: Covalent Names and Properties
Run the name machine, then melt and test in the property lab.
Chemistry Part C: Equations and Conservation of Mass, plus Two Videos
Two videos, the sealed bag vs. open cup, the balance builder.
Chemistry Part D: Reaction Types, plus the Lab Bench Mass Mystery
Five reaction types, a video, then the Lab Bench Mass Mystery.
Wrap-up: Solve the two white powders
Go back to the two white powders at the top of the unit intro and explain, with what you learned, why salt and sugar look the same but behave so differently.
Bonus: 1v1 HS Chemistry
- Only when you and a partner have both finished every stop.
- One computer, two players: Red uses the W A S D keys and Blue uses the arrow keys. It needs a keyboard, so it will not work on a phone.
- Press Enter the Arena, pick a game, and play to 3 wins.
For teachers
Post this link for your students
Students move through six free tobinscience.com resources in order: the Chemistry unit intro, six one-minute Simple Science videos (three at Stop 2, two at Stop 6, one at Stop 7), the unit vocabulary, the full Chemistry section (Parts 1–6: an electron-dot bonding scene, a charge-tower criss-cross machine that writes and names every ionic formula, a covalent name machine, a property lab with a temperature slider and a conductivity tester, a sealed-bag versus open-cup balance, a balance builder with an atom model and tally chart, a plan-and-carry-out investigation and the five reaction-type patterns), the Lab Bench Mass Mystery, and a 1v1 review game for early finishers. Every answer comes from what the page shows, matching SPS2a–c and SPS3a–b.
Time: about 80–85 minutes (two 45-minute periods, or one block)
What students need
- One Chromebook or computer per student (the 1v1 bonus needs a keyboard and two students on one computer)
- Headphones are optional (the six videos are about one minute each)
- No student accounts or sign-ins; nothing to install
Every stop at a glance

- Bonus: 1v1 HS Chemistry
Good to know
- The Formula Builder and Equation Balancer rounds, every endless-practice score, the mystery-substance data and the Lab Bench masses are randomized, so those answers vary. The simulation readouts (bonding results, criss-cross steps, machine names, melting points and bulb results, 25.0 / 22.8 g, balance-builder coefficients, investigation data, the reaction-type table) are fixed and match the key.
- Stop 1 activities award electrons that are saved only on that device; students write their score on the sheet.
- All six Simple Science videos are used: the SPS2 group at Stop 2, Conservation of Matter and Balancing Chemical Equations at Stop 6, and Types of Chemical Reactions at Stop 7 (it shows four patterns; the page adds combustion, and the sheet asks for it).
- Naming follows the unit notes: no prefixes on ionic names, a Roman numeral only for Fe, Cu, Sn and Pb, no "mono" on a first element, monoxide / pentoxide / decoxide; criss-cross, then reduce; balance with coefficients only.
- The 1v1 bonus is for pairs who have both finished. It is head-to-head review of the whole chemistry unit.
- The page also has endless mixed practice, worked examples, real-life cards, myths, a 10-question bank and a reaction-type sort that the webquest does not visit; with the Counting Atoms, Balancing Chemical Equations and Naming Binary Compounds tools on the unit page, they make a good warm-up the next day.
- Short on time? Stops 1–3 make a good first day and Stops 4–7 a second day.
- The printable student webquest and its answer key come with the Word / PDF webquest download. This page holds no answers, so it is safe to post.
