Titration III: find the concentration of an unknown HCl solution

Students run the Acid Base Titration III remote lab hands-on — controlling the titrant flow, watching pH and colour respond, and judging the endpoint themselves — then read the burette and use the 1:1 reaction to find an unknown hydrochloric acid concentration, with attention to uncertainty.

• Explain what a titration measures and why catching the endpoint is the key skill.
• Run the remote titration hands-on: add the titrant with the faucet and drop-by-drop controls and watch pH and colour respond.

Includes student questions and response prompts.

• Acid-Base Titration I
• 60 min
• High school chemistry / upper secondary science
• English

Titration: endpoint, stoichiometry, and uncertainty

Students use the Acid-Base Titration remote lab to estimate an endpoint, calculate an unknown citric-acid concentration, and justify uncertainty from real pH-volume data.

• Identify titrant, analyte, indicator, endpoint, and equivalence-point evidence in a titration.
• Use the remote lab to collect or cite pH-volume rows around the endpoint.

Includes student questions and response prompts.

Visual programming with a real Arduino (2/4): sequences and loops

Students build LED sequences with visual blocks, replace repeated copies with loops, and test timing on a real Arduino board.

• Create a light pattern with a clear sequence.
• Use a loop to reduce repetition.

Visual programming with a real Arduino (3/4): inputs and decisions

Students use visual blocks to read an input, make a decision with a threshold, and verify LED behavior on a real Arduino board.

• Read an input and confirm it changes before deciding an output.
• Use an `if / else` condition with a comparison and a threshold.

Includes student questions and response prompts.

Visual programming with a real Arduino (4/4): mini-controller

Students combine visual-programming inputs, decisions, and outputs to build a mini-controller and document real-board test evidence.

• Design a mini-controller with input, decision and output.
• Test the program with two defined cases.

Includes student questions and response prompts.

• Free Fall
• 35 min
• Primary education (ages 10-12)
• English

Which falls first, the heavy ball or the light one?

Students use the Free Fall remote lab to predict, observe, and compare whether a heavy ball reaches the floor much sooner than a light ball.

• Predict which of two balls you think will reach the floor first.
• Observe and record the fall time shown by the lab for each ball.

Includes student questions and response prompts.

• 40 min
• Upper primary science
• English

Will it float?

Primary students predict, test, and explain whether real objects float or sink in the Buoyancy remote lab.

• Predict whether selected objects will float or sink.
• Use the remote lab to test predictions by moving each object down into water.

Includes student questions and response prompts.
