Estimania

Question
At each station will students be allowed to touch/manipulate any and all props?  For example, given an object and told to estimate weight can they lift and pass around the object.  Or if given an object and a box and asked how many of X fit in the box, can they put the one object in and out of the box at will?  Or, if given a container and asked to estimate the # of Y in the jar, can they lift the jar and turn it around at will?  Basically is there anything that they won't be able to touch, feel, lift, etc?


Answer:
For majority of the questions the students may be able to touch the props. There may be one or two questions where they will not be allowed to touch. But questions like number of items in a jar, they will be allowed to take the closed jar in their hands and estimate.

Dragonflies

Question:
I see Dragonflies generically mentioned in the Study Guide. There are many different kinds of dragonflies such as darners, skimmers, etc. Will the students be tested on each of them and are they expected to know each darner's/skimmer's family names and characteristics?
How many total questions can we expect for 4th grade and 5th grade students for Back to Nature?



Answer:
The students will not be expected to distinguish between different kinds of dragonflies.  They should be able to answer questions about dragonflies as an order.

We are still finalizing the test.

Acids, Bases

Question:
It says that students are responsible for knowing only the Lewis Acid and Base definition.  (As a side note, this definition of Acids and Bases is not even tested in AP Chemistry let alone high school chemistry and instead the other two definitions are). 

However on the slide referencing what they need to know about acids and bases the following is listed:

"(5th grade only) What makes something an acid or base [H+]" which would be referencing the more commonly known definitions and NOT Lewis acid and base (electron donors/acceptors).
 
 
 
 
Answer:
There are many different definitions for an acid and base, and I reduced the definitions that would possibly be directly tested to a Lewis Acid and Lewis Base. This is an elementary school event and students will be required to have a basic understanding of the pH scale, in particular how to test for pH and what the results generally mean. Questions regarding calculating H+ ion concentrations for acids & bases will not be asked.

Water Rockets

Q:   We have both a 3rd/4th grade water rockets team and a 5th grade water rockets team that practice together.  Our 3rd/4th grade team has only one 4th grader and it's become clear that the 5th grade team is a better match for him.  Is it possible for him to move to the 5th grade team?

(We know that the general policy is that students must stay in their grade level but we were hoping with the combined teams that this might be a possibility.) 

A:  A 4th grader may not compete on the 5th grade team.  

The combined 3rd/4th grade team for Water Rockets is by design and consistent across all schools.  There is an understanding that a combination of 3rd and 4th graders will comprise each team.   A student who is not a 5th grader competing on a designated 5th grade team would be an exception to the policy and is not allowed.

Example for night sky test

To Infinity and Beyond:
Our co-supervisor has made a brief video demonstrating what the replacement to the dome test might look like to the participants. 

Here's the link to the youtube:

On Target

On Target Range Announcement

The target will be marked on the floor at a point between
7 and 8 meters.   (that means it could be anything between
those two values, not necessarily at 7.5 meters).

Also just another reminder of the event change this year.   The
measurement for scoring will be made from where the
rocket comes to rest.
