Metric untis

there are metric units all around us.

some examples are


  • liters of soda
  • when you run a 5k run that is in metric units
  • degrees Celsius you use on a thermometer
  • and second is a unit you use to measure time 

 

Estimating distances

I think the front of my house is about 10 meters or about 30 ft. I think this is a resonable estimate because i measured the inside part of my house that was around the same size of my front yard.

distracted driving

I think distacted drivers are bad because they make driving risky for the rest of the safe drivers.For example I remember one time I was in my aunts car driving to her house. W were on the highway and this guy in a big truck stopped fast. He said he thought the car in front of him stopped. Luckily we weren't going fast at the time.That is one time i was in a incident with a driver was distracted.

Reaction Time

A reaction time is is how long a person or thing takes to react to a scenario. Your reaction time isn't always related to science class but also used in your daily life. For example if you are speeding and suddenly there is a red light,your reaction time is how long you take to react to the red light. Also if you are walking on ice and you fall your reaction time would be how long it takes you to grab the wall or railing etc. Your reaction time isn't always about time but about distance for example if your cooking and you drop something how quick you catch the idem. That is what a reaction time is and how it is around you every day.
