QuestionsFrequently Asked Questions: This page contains answers to common questions of students and parents.
protons = the atomic number electrons are almost as easy as protons. If there is NO + or - behind the chemical sybol. The element is NEUTRAL. so the electrons are equal to the protons. If there is a PLUS + behind the sybol, the element is POSITIVE, that means it has lost 1 electron (negative charge) for each +. If it is -, it has gained 1 electron for each - symbol. Example 1 F-, F normally has 9 electron, with the - it now has 10. EXAMPLE 2 Mg ++ Mg normally has 12 electron, with 2 +, that means it has lost 2 electrons, so there are now 10 Take the ATOMIC MASS and subtract from it the atomic number, that is the neutrons. Neutrons = protons + neutrons no a charged atom. has gained or lost e-'s the mass on the PTE is an n average, Isotopes are EXACT. so the neutrons will be different, why is there so much math in the physics unit? To best understand some concepts of physics, you need to see the math that proves it. For example Kinetic and potential energy in a system Are the grade sheets worth points YES. 5 per week. These are mini finals that are mandated by the district. How can my student Test Out of freshman science? 1st- pass the physics and chemistry essintials tests with 80% or above 2nd--earn my recommendation 3rd-- Pass the test the high school will give those students who meet standards 1 and 2 with a 80% IF A STUDENT MEETS OPTIONS 1 AND 2, BUT FAILS 3, THEY CAN STILL TEST OUT WITH A ADVANCED SCIENCE CSAP SCORE. Do they earn HS credits if they test out NO what is the advantage of testing out? This will put the student on a more advanced science track that will help prepare them for college. Will it hurt my childs chances in college if they do not test out? NO. they will still need at least THREE science credits at the high school. Integrated science would be one of them. NOTE MCHS graduation criteria say they only need 2 science credits. State colleges in Colorado require 3 HS science credits. What is the purpose of the mousetrap car? The mousetrap car meets school district standard 1. This is the standard on scientific design and experimentation. Students will need to build a car to the standards set forth and meet the performance criteria. This project is equal to a test grade. It also is extremely fun for the kids and I DO NOT MIND IF PARENTS AND KIDS WORK TOGETHER> Where can I find help on the MT car. There are a set of SAMPLE plans in my room on the wall. Do a google search for tips on mousetrap cars. Look at images and video on google and youtube of MT cars. NO Can we buy plans for the mt car Yes, BUT I have a set in my room they can look off of. I just do not think I can help my child with the MT car. I can help, another parent, grandparent, friend etc. Can two kids work together on the MT car? Yes BUT they each need to turn in THEIR OWN CAR. What is the hands on unit the last 3 weeks of school. This is more of the standard one. In this unit we will focus on hands on activities. Tooth pck bridges, and their science project. More later |
