This week in science we finished our tests and put a finish on our chairs. So that they last longer and they are very shiny, we also started working on our digestive journey projects and we watched a video about this weird dude and looked at some other people’s slides that they had done. Then after that, we did an experiment with saltines where you crush one of them up in your hand and you chew the other one for 3 minutes, it was really gross but then you put 30 MLS of water into each of them then you put in a chemical and it changes the color and the one that was chewed was a lot lighter because of all the chemicals in our mouths that are used to digest the food and the crushed one was darker.

How do the chemicals get to our mouths?

How does the color part work?

was this a new experiment?

This week we got back from the break and we missed school on Monday due to a power outage then Wednesday we study for the test we started on Thursday and we are finishing it tomorrow. So since we didn’t do very much I watched a TED-ED about how stress can make you sick.

Stress is not just an emotion it’s also a hard-wired physical response throughout your entire body. In the short term, stress can be advantageous but in long term, it overwhelms your body and damages certain organs.your adrenal gland releases your stress hormones cortisol, epinephrine, and Norpinehrine and they travel through your bloodstream they easily reach your blood vessels and heart (they are also known as adrenaline) and adrenaline causes your heart to beat faster and raises your blood pressure over time causing hypertension. It increases so many diseases and causes a lot of problems in your body. If you want a longer life you have to cure the cause of your chronic stress.
