Making Milk Without Cows?(Article Blog) - Weekly Blog #22

Summary 

The California-Based Perfect Day company has figured out the the secret to making milk without using cows. This milk is completely lactose free, and is produced through their factories. The owners founded their company due to the increasing demand for lactose free products. This is because using environmental safe foods can help the earth drastically in several factors. Using a revolutionary technic, this company has single handedly changed the way people would want to live their lives. Making milk using these methods creates a much more environmentally safe milk that can be developed into several other products.

S&EP - Constructing explanations and designing solutions

The main factor behind making products like this is to create a much more efficient and environmentally safe product. The magic behind the milk is using the strain of yeast that is produced in the USA Agricultural Department and 3D printing a sequence of cow DNA. They then insert the DNA it into a specific area of the yeast. This allows milk proteins to be formed, and with the help of some other products, the milk is prepared. This lowers the land consumption by 91%, the water consumption by 98%, the energy consumption by 65% and greenhouse gas emissions by 84%. This definitely designed a solution that works for everyone, and is much more Eco-friendly.

Ph levels - Weekly Blog # 21

Summary

This week in science, I learned about the different pH levels, and what they represent. At its core, pH is the acidity of a substance. A pH scale provides a versatile gouge on how acidic a substance is, and can be used in several circumstances. The lower the number on the pH scale, the higher the acidity. An example of a highly acidic substance would be something like battery acid. The higher the number on the pH scale, the higher the base. An example of a very basic substance would be something like soap.  A neutral pH is a substance that has a pH of around 7 and has no strong leanings toward an acid or a base. An example of this could be something such as water or blood.

S&EP - Conducting investigations

This week, we were able to do a physical test on how acidic or basic we could make our baking soda solution. We used vinegar to make the solution more acidic and sodium carbonate to make it more basic. We had separate wells, each having cabbage juice in them. This allowed us to see the change in color as we made the solution more or or less acidic. Depending on whether the cabbage juice became more pink or green determined on how the pH of the juice was changing.

XCC - Cause and Effect

There is a great factor of cause and affect that was present this week while studying pH levels. When we added more vinegar to the baking soda solution, it caused it to be more acidic. The affect of a more acidic substance to the cabbage juice was having a more red color. This same cause affect relationship can also be applied to when we added more sodium carbonate to the solution. It cause the acidity to lower and the solution to become more basic. The affect of this was a lower pH, which was reflected onto the more green color of the cabbage juice.
