As mentioned, the starter kit comes with the first two experiment kits too and provides a brief summary of the four experiments that are included in the kit. Each experiment can be explored by using the links associated with each experiment kit below:

Experiment #1 – Tin Dendrite
Link: https://melscience.com/en/experiments/tin-dendrite/

Tin dendrite begins to grow as the electric current flows from the battery through the clip towards the other clip. The metal crocodile clips are acting as electrodes by allowing the electric current to flow through them. The tin crystals form in the petri dish as the current flows. This process is called electrolysis and is a chemical reaction induced by an electric current. Tin has special properties allowing it to form crystals that are visible. Here is the chemical reaction when the tin reduction takes place.

Experiment #2 – Burning Sugar

Burning is the oxidation reaction of a substance, which removes electrons; breaking bonds to oxidize molecules. At first during the experiment, the sugar cube would not catch on fire on its own because sugar takes time to oxidize. However, once the cube was covered in ash, it caught fire and burned. The ash acts as a catalyst and to increase the rate at which sugar burns. This is because the ash contains sodium and calcium salts that bolster the combustion of the sugar cube reaction.

Experiment #3 – Sugar Snake
Link: https://melscience.com/en/experiments/sugar-snake/

In this experiment, a fuel of sugar and sodium hydrogen carbonate is mixed together with hexamethylene- tetramine, forming a burning snake-like object. The snake is made of carbon that is the product of the heated sugar. During the reaction, carbon dioxide and water vapor is given-off that causes the snake to grow. Here are the three chemical reactions that occur in the formation of the “snake.”

1. C12H22O11 + 12O2  12CO2 + 11H2O
2. C12H22O11  12C + 11H2O
3. 2NaHCO3  Na2CO3 + CO2 + H2O

Experiment #4 – Tin Hedgehog

Link: https://melscience.com/en/experiments/tin-hedgehog/

The zinc metal reacts with the tin chloride to form tiny crystals on the surface of a zinc pellet. The tin precipitates and forms these crystals creating the tin hedgehog. The process of the needle-like structures growing in the solution is called crystallization. Here is the reaction that takes place.

SnCl2 + Zn  Sn + ZnCl2

Conclusion:

Each experiment is designed to show a different chemical reaction and we found that they worked very well. Hence, there is no doubt that the Mel Chemistry Starter kit is excellent and will no doubt be useful for teaching chemistry lessons.

This week in education news, North Dakota’s superintendent is requesting teachers to review new academic standards; California teachers find new science standards fun, but expensive; four New York students injured in a chemistry experiment gone wrong; several Wisconsin school districts are trying a new method of evaluating what students learn; Veteran astronaut Dr. Bernard Harris named new CEO of NMSI; new Gallup poll reveals that superintendents have a hard time finding quality teachers; Houston-area administrators are using physical activities to better engage students in STEM courses; and Ohio high school students may soon be allowed to replace the Algebra 2 graduation requirement with an advanced computer science course.

Review Of New Academic Standards Begins

North Dakota’s superintendent is asking teachers statewide to review academic standards for science, health, early learning and the arts as the process for drafting new benchmarks gets underway. State Superintendent Kirsten Baesler is asking teachers who specialize in science, health, the arts or early learning to apply to serve on one of the four content committees that will draft standards.

Fizz! Pop! Bang! Teachers Find New Science Standards Fun, But Costly

With their emphasis on hands-on experiments, California’s new science standards have turned classrooms into noisy, messy laboratories. That’s been popular with students and teachers who say it’s a more effective way to learn science than studying textbooks and memorizing facts, but the cost of all those underwater robots and exploding chemicals has left some teachers wondering how they can successfully implement the standards with ever-restricting budgets.

New Florida Law Expected To Increase Conflict Over Textbooks

In Florida, some say global warming and evolution are a hoax and should not be taught in textbooks unopposed. Others say their local school’s textbooks shortchange Islam’s role in the world, while their opponents argue it’s the danger posed by Muslim terrorists that’s underexposed. Under a bill passed by the Florida Legislature this year, any district resident — regardless of whether they have a child in school — can now challenge material as pornographic, biased, inaccurate or a violation of state law and get a hearing before an outside mediator.

By 2022, America Will Need 1 Million More College Grads With STEM Training Than We Are On Track To Produce

As our economy evolves, we must evolve with it, developing a workforce prepared to meet the demands of a new economy. Now is our chance to build a workforce ready to succeed over a lifetime, not just over the next three to five years. At the heart of the opportunities and risks we face in a new global economy is the increasing value of skills rooted in STEM. Indeed, 10 of the top 14 fastest-growing industries require STEM training. To keep up with the projected growth in demand for STEM jobs, America will need an additional 1 million more college graduates with STEM training by 2022 than we’re on track to produce.

Some Wisconsin Schools Use Standards-Based Grading…What Is That?

Several Wisconsin school districts are trying a new method of evaluating what students learn. It’s called “standards-based grading,” and it’s different than the typical A-F grading system people may be used to. Advocates believe the new approach will replace the old system. But, in order for the practice to catch on, it will take a shift in mindset from both parents and educators. Read the article featured on WUWM.com.

ESSA Is A Big Piece Of The STEM Equity Puzzle

High-quality STEM education not only has the potential to foster curiosity and creativity in students, it is critical for U.S. economic growth. But both words and plans are insufficient without follow-through. To best promote student success in STEM, we need both adequate funding and implementation of smart and equitable policies by all states and the District of Columbia.

Can Computer Science Replace Algebra 2?

Should students be allowed to take computer science instead of Algebra 2? Ohio schools could be heading in that direction. House Bill 170 would let high school students replace the Algebra 2 graduation requirement with an advanced computer science course. Students could also choose to take computer science in place of some other science courses. Read the article featured in Education Week.

I’m teaching a science methods class. I’d like to know: What was the most important thing you learned in your undergrad science methods classes? What do you wish you had known about science teaching that you didn’t learn in undergrad?
– L., Illinois

This post to an NSTA e-mail list produced excellent responses and I wanted to share my thoughts.

Important things I learned in university:

• Reflect on everything you do, every class. Ask yourself: Did they get it? Is this working toward my goals? How can I tell they learned this? How could I have taught this differently?
• Check over and test everything you do in advance. Practice demonstrations and labs to uncover any issues, modify as needed, and resolve with safety concerns. Even labs that look “foolproof” on paper could take twice as long in the classroom. Check all handouts for errors and out-dated information.

Important things I learned in my classroom:

• You teach students, not science. Students want to know that a teacher cares about them. Flexibility, understanding and compassion are good traits.
• Resist being the “sage on the stage.” There is no way to know everything so admit when you don’t know something. Turn perplexing questions into learning experiences for the whole class, including you. Make sure that the students are active in their learning instead of passively listening to you.
• You do not have to create everything yourself. Use premade materials that fit perfectly; modify the materials that don’t; and create new materials when you can’t find anything that fits.

Hope this helps!
