Chemistry in the classroom (Cyanotype-Mel Science)

This month's chemistry experiments are "Painting with light" and Cyanotype. We used light and citric acid to create pictures and to write with.

This chemistry set came with the following:

1. Ammonium carbonate x2
2. Ammonium iron (III) sulfate x2
3. Citric acid x2
4. Potassium hexacyanoferrate(III) x2
5. Film negative
6. LED for blueprint x2
7. Absorbent x6
8. Battery holder
9. Crocodile clip wire x2
10. Double-ended spoon x4
11. Experiment card x2
12. Instructions
13. Paper sheet x7
14. Pin opener
15. Plexiglass
16. Protective gloves
17. Transparent bag with valve x2

Instructions

Painting with light: Learn to draw using a diode

Cyanotype: Create an image using light

Marble Paper

We took paints and milk and created marble milk paper in the classroom this week. It was a lot of fun to see the designs that created with each sheet we ran through the milk/paint mixture. It's a simple process of one cup of milk and water colors, food coloring, or paint applied to the milk surface and a plain sheet of paper laid on top. We think the process would have been more uniform with acrylic paints/oil-based paints, but it was still a fun activity with what we used. We allowed the paper to dry in the sunshine.

Chemistry in the Classroom (Chemistry of monsters-Mel Science)

We recently started a subscription to Mel Chemistry and our first science experiment came in the mail this week. It's a chemistry lesson named: "Chemistry of monsters." 

For one of the experiments it's a Sugar Snake. We used baking soda and sugar on a heated plate and grew a snake from the two. The chemical reaction with the soda, and sugar, when heat is applied was a good lesson in chemistry, for sure. 

This chemistry set came with the following:

1. Anthocyanin
2. Citric acid x2
3. Solid Fuel
4. Sodium carbonate x2
5. Sodium hydrogen carbonate x2
6. Aluminum foil x5
7. Double-ended measuring spoon x2
8. funnel
9. Liquid soap x2
10. Protective gloves
11. Syringe without needle
12. Thermochromic sticker x2
13. Wooden stick x4
14. Experiment card x2
15. Instructions
