Motion Sensors I have a motion detector at are house also, ares is the laser beam one that when you cross the beam it doesn't hit the other side and it prevents the garage door for crushing the car or me. A con for this device is that you can jump over it so the beam isn't interrupted. The SONAR type one is a good device for motion detecting because it is hard to avoid really and found it very interesting how this motion sensor worked what I understood what it did was it sent out waves and that when the wave was obscured it would turn on a light or make a sound. The types of these I've seen are the owls that when a bird or squirrel come to your garden or door it makes a noise to scare it away. The last type of motion detector is the infrared radiation and the the thing that, that makes me think of is call of duty with the IR scope witch maker the enemy glow because he is warm blooded, also I think of night vision googles with the green at night and then when you see a person it makes them or a warm blooded critter glow.

Austin, Much better! I see you made some connections with your personal experiences here. Be sure to clearly catalog things you learned and things you knew. 5 stars. MW

Something I knew was what distillation is it is when you boil water and it goes through this tube through the sidearm into the collection tube. As the temp rises other carbons are collected. I found the reflux really interesting when the water condenses at the top and falls dow into the tube.

Austin, Short and sparse. Please make a greater effort. 3 stars. MW

Knew 1. It fizzs 2. It shots up like a geyser 3. It has somthing to do with CO2 release

Learned 1. The chemical reaction of shaking a soda 2. I got an in depth look at why the soda burst open 3. And how sharp edges in ice makes it bubble more

Austin,

Pretty basic here. Use sentences and be sure to follow the rubric. When you see it fizzes what do you mean? Try to communicate in a clear concise way! 3 stars. MW
