Making your own Distance Lab... Visual Storyboard

What activities would help students understand concepts related to understanding the phenomenon?

Can I find a suitable experience already made? What scaffolds do my students need to be successful?

How did I plan for students to drive what they do by questions that they generate?

What data can you post or could students generate that can be analyzed that helps illustrate the concept being explored?

Create a visual storyboard

Taking the time to layout what students will do in the lab visually by either sketching the steps or making a flow chart of what they will gain as they progress through the experiences will help you think as the student and reflect on what they will be getting out of the experiences.

Look at the phenomenon of grape Kool-Aid added a drop at a time onto a napkin. What do they notice and wonder? They can use Jamboard to record their questions on Sticky Notes (Engage part of the 5E Sequence)

Ask students to explore black or purple water soluable pigment mixtures at home with a napkin and some water? What do you think is going on? (Explore/Explain part of the 5E)

Ask students to develop an initial model of what they think is going on. You can use Google Draw to record your individual thinking (Explain part of the 5E)

Plan for ways for students to look for answers to questions that were generated via Notice and Wonder! What is Chromatography Reading, videos, diagrams. They can look at any or all. They can then revise their models (Explain part of the 5E)

Put videos of different types of chromatography happening or show live examples of Paper, Column with a syringe, Column with a straw.

Add other examples of chromatography happening with different solvents. videos and still images. (Explore part of the 5E)

What is Chromatography 6-8 7-9-17.docx

Remind them to look at other readings about Chromatography and videos to help gather more info for their models

(Explain and Elaborate of 5E)

Have them to select a question that can be explored through experimentation at home. This can be done in pairs (food coloring, or marking pen). (Evaluate and Explain)

Ask students to use a Google Doc as a Hyperdoc to add all of their thinking, observations in their documentation of their method. (Evaluate)

Ask students to revise their models again after developing their own experiments to answer questions. (Elaborate and Evaluate)

Share with another group and evaluate each others method. (Evaluate)

Ask students to revise their models after sharing with others groups.

Develop a plan for the next set up experiments needed to confirm your method or improve your method

Online Symposia on Chromatography

Ask students to produce a 3 slide presentation on their method of separating a mixture using Chromatography.

HS NGSS PS1-3

HS-PS1-3: Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles. [Clarification Statement: Emphasis is on understanding the strengths of forces between particles, not on naming specific intermolecular forces (such as dipole-dipole). Examples of particles could include ions, atoms, molecules, and networked materials (such as graphite). Examples of bulk properties of substances could include the melting point and boiling point, vapor pressure, and surface tension.] [Assessment Boundary: Assessment does not include Raoult’s law calculations of vapor pressure.]

MS-ETS1-4

MS-ETS1-4: Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved. [Clarification Statement: N/A.] [Assessment Boundary: N/A.]. If modifying this activity to suite middle school students, you might consider starting with a problem, like you have a mixture of two pigments (red and blue) that you need to design a method to separate and purify.
