Getting Started with Arduino
An introduction to using the Arduino with Manylabs lessons, including how to install the WireGarden plugin.
Freezer / Incubator
This page describes how to build a freezer/incubator using a thermoelectric device.
Made for use with the Carolina Enzyme Catalysis lab kit, in this lesson students can watch an example titration, enter data for each lab activity, verify calculations, plot reaction rates, and answer review questions about their lab results.
Requirements: Carolina Enzyme Catalysis Kit 74-6431 (1 station), 74-6430 (8 stations), OR 74-6432 (8 stations with burets); potato; boiling water bath; test tube rack; test tube holder; ice bucket; ice
This lesson guides students through the classic introduction to pH by asking them to hypothesize about, and then measure, the pH of common solutions.
Endothermic and Exothermic Reactions
This lesson explores two chemical reactions, one endothermic and one exothermic, using a Grove temperature sensor and easily available materials.
Requirements: Grove Temperature Sensor, Ice, Water, Citric Acid, Sodium Bicarbonate (Baking Soda), Steel Wool, Vinegar, Beakers
In this lesson, students will explore an example of bioluminescence and see how temperature affects the reaction.
Requirements: Carolina ATP Firefly Kit, Test Tube Color Sensor
Chromatography and Polarity
Learn about chromatography by working with example chromatograms. Marker pigment chromatograms introduce the concept of polarity while kale pigments provide a real world example of natural mixtures. Use the known polarities of solvents to determine which pigments are polar and non-polar, then view their chemical structure to find out why. Finally, calculate Rf values for each kale pigment.
