pH Scale

Test the pH of things like coffee, spit, and soap to determine whether each is acidic, basic, or neutral. Visualize the relative number of hydroxide ions and hydronium ions in solution. Switch between logarithmic and linear scales. Investigate whether changing the volume or diluting with water affects the pH. Or you can design your own liquid!

Neuron

Stimulate a neuron and monitor what happens. Pause, rewind, and move forward in time in order to observe the ions as they move across the neuron membrane.

Natural Selection

Explore how organisms with different traits survive various selection agents within the environment.

Molecule Polarity

When is a molecule polar? Change the electronegativity of atoms in a molecule to see how it affects polarity. See how the molecule behaves in an electric field. Change the bond angle to see how shape affects polarity.

Membrane Transport

Add different biological solutes to either side of a cell membrane and observe their behavior based on solute properties and concentrations. Add transport proteins and uncover some of the common mechanisms for transporting solutes across a cell membrane.

Gene Expression Essentials

Express yourself through your genes! See if you can generate and collect three types of protein, then move on to explore the factors that affect protein synthesis in a cell.

Density

Why do some materials like wood float in water, and others don’t? Interact with blocks of different materials, including a custom option by modifying their mass and volume, to explore the effect on the density and discover the conditions for sinking or floating in water. Play detective to determine the material of each block by comparing its density with the values in the table.

Color Vision

Make a whole rainbow by mixing red, green, and blue light. Change the wavelength of a monochromatic beam or filter white light. View the light as a solid beam, or see the individual photons.

B5.1 Recycling old materials (student instructions)

Experimentation instructions for Experimento | 8+:Detailed instructions and questions for students on conducting the subexperiment “B5 Recycling – Recycling old materials.” A short introductory text presents the experiment to the students. Then the research question is stated.The students make guesses and exchange ideas about possible solutions. This is followed by a list of the required materials as well as clear, step-by-step instructions for setting up and conducting the experiment in the small group. Observation questions for checking the results can be answered right on the instructions.There are also reflection questions for evaluating and incorporating the experiment and establishing the reference to the opening question. An additional research project encourages the students to do further research.Documentation aids in the student instructions or a blank form to be filled out is provided for documenting the experiment.Information and ideas:• Observe the safety information in these instructions, in the teacher instructions related to the experiment, as well as in the document “Safety information on the topic of the environment – Experimento I 8+” and discuss this information with your students. • Also observe the applicable safety guidelines for your school.• These student instructions are also available as a Word file.
