IRP Misconceptions Made by Mrs. Gus

But First… Late Assignments § When was your IRP PP due? § December 20 th by 11: 59 pm to Turnitin. com § How could you find out when it was due or check? § § IRP Timeline Mrs. Gus’s online calendar The white board Weekly parent messages § Science late policy is “All assignments and projects will receive a deduction of 20% of the possible points for each day it is late. After five days, late work will no longer be accepted. ”

Late Assignments § If you turned in your 1 -2 days late then your project will stick with the late policy as stated in the syllabus. Ex: 1 day late is 20% off your score. § If you turned in your project in Janaury, no matter the excuse, the highest grade you will receive is a 50%. § Mr. Alcala approves of this plan. § Missing assignments will receive is a zero.

Control Group Misconceptions § What is a control group? § The group with the “normal” condition for the IV. § Do all experiments have control groups? § No § If control group is present, do you need to test the control group? § YES! That is the point of a control group. Control groups are the standard to which comparisons are made in an experiment. § Does a control group count as one of your three levels of your IV? § No

Constants VS. Control Groups § Are constants and control groups the same thing? § NO § Constant: kept the same throughout the experiment § Examples: The type of plant is kept the same, the p. H of water, etc. § Control Group: The group with the “normal” condition for the IV. Used for comparison. § Example: Type A plant normally should be watered 100 m. L of water every day. Will be compared to levels of the IV

Independent Variable (IV) VS. Levels § Can you use the terms levels and variables interchangeably? § No § Independent Variable: the variable you purposely change. § Example: Watering plants with different amounts of water. § Levels of the IV § This is the specific ways the IV is being varied § Ex: Watering plants with 10 m. L, 20 m. L, 30 m. L of water

Dependent Variable (DV) § Dependent Variable: the variable that is being observed/measured, and changes in response to the independent variable. § Example: The height the plants grow because the amount of water provided was changed. § DV Units § There are correct ways to measure/observes responses to change. § Ex: Speed is measured as distance/time, NOT in seconds or minutes. § How can you check to see if your units are correct? § Search the internet § Ask a science teacher § Talk to an expert

Finding Out the Why § Student: “Aluminum is the best metal for conducting electricity. ” § Teacher: “Why? ” § Student: “Because it is. ” § Teacher: “What evidence do you have? ” § Student: “Uhhh…” § Student: *Does not try to find the answer. *

Find Out the Why § Student: “So the reason I got the results I did was because there are two regions on a tennis racket. There is a “sweet spot” and “dead spot”. The sweet spot is the best location to hit the tennis ball off of. ” § Teacher: “Why? ” § Student: *Student works hard at figuring out answer. * § Teacher: “Why? ” § Student: “Located on a tennis racket is a region known as the “center of percussion” (COP). This point, when struck, will result in the forward translational velocity and the backward rotational velocity being equal and opposite. This causes the hand of the player to feel the force of the hit, which causes the racket to rotate. ”
