Which will flash the brightest: a hot or algid glowstick? (Video apparent in class)Which will afterglow the longest: a allowance temperature or algid glowstick? (Conducted at home)
1. Introduce yourself.
Tell the acceptance your name and that you adulation science.
2. Find out what the acceptance already apperceive about glowsticks and analyze what blazon of aglow or light-up accessory you will analyze during your time with them. “Today we are action to allocution about the abstruse science central glowsticks and what you can do to accomplish the afterglow brighter and aftermost longer. First, I would like to apperceive what you already apperceive about glowsticks.”
Hold up one glowstick, not yet activated, so that acceptance are ablaze on the blazon of accessory they will apprentice added about with you.
“Raise your duke if you accept anytime acclimated a glowstick. Sometimes these are shaped like a baby stick, necklace, or baton that gives of light.”
Ask students:
“We will analyze the blazon of glowsticks that ablaze up back chemicals mix together, not by a switch. Glowsticks are safe to use in emergency situations because there is no electricity. They are alike advantageous underwater!”
3. Accord a ample overview of your lesson.
“When you actuate a glowstick, you are accomplishing chemistry! We will watch a video that shows two bodies investigating whether temperature affects the accuracy of the ablaze appear from a glowstick. Afterwards the video, we will allocution about an agreement you can do at home with two glowsticks that I will accord to anniversary of you.”
4. Alpha the video to acknowledge what is central a glowstick and afresh abeyance it to ask the catechism at 1:12-1:29. The apprentice in the video holds a glowstick and describes what he sees central it. The chemist explains that chemicals are carefully kept abstracted so that the actinic acknowledgment happens back we appetite it to light.
Ask students:
5. Resume the video and ask the catechism at 2:02-2:18. The chemist explains that sometimes chemists appetite to adapt or change the actinic reaction. One way to do this is through temperature.
6. Watch the agreement on video to acquisition out which absolutely shines the brightest.
The chemist pours hot, cold, and allowance temperature water. The apprentice aeroembolism all three glowsticks, which accomplish an aural snapping complete as the bottle ampule central breaks. Both chemist and apprentice agitate the glowsticks and abode them in the three cups of water. They analyze the accuracy of the ablaze in the three cups and adjustment them from atomic ablaze to the brightest.
7. Pause the video amid 5:28-5:44. Accept a chic altercation about authoritative a hypothesis.
Ask students:
Return absorption to the video.
The apprentice switches the glowsticks in the hot and algid water. While we delay for results, a atomic archetypal action reveals the aberration in the acceleration of baptize molecules in cold, allowance temperature, and hot water. Once the apprentice and chemist acknowledgment to the experiment, the glowstick in hot baptize is now the brightest and the glowstick in algid baptize is now the dimmest. The chemist asks, “Is your antecedent correct?” The apprentice smiles because it is! Many of your acceptance will feel accurate as well.
8. Continue with the video which explains what is accident at the atomic level. This allocation of the video explains the affiliation amid the acceleration of the molecules and the accuracy of the ablaze empiric by acceptance during the on-screen experiment.
An action introduces the abstraction that a actinic acknowledgment occurs back molecules bang aloof right, atoms rearrange, action is released, and the resulting new molecules move abroad from one another. Note that the action does not represent absolute compounds. It is simplified to serve as a acquirements apparatus for elementary students.
The video adds in the terms chemiluminesence and bioluminescence as benefit content. Acceptance do not charge to apperceive these agreement in elementary school. However, they may accept accomplished both in their lives. Introducing the agreement serves as a way to accompany animosity of appliance appear chemistry.
9. Make the affiliation amid acknowledgment bulk and the time it takes for a actinic acknowledgment to end. Students may accept abstruse about similes and metaphors in their accent arts classes. These comparisions are about alien in fourth, fifth, or sixth grade. The affinity acclimated in the video relates kids active against a accomplishment band to the time back the actinic acknowledgment that makes glowsticks ablaze up will appear to an end.
Stop the video amid 8:38 and 8:42.
Ask students:
Advance the video hardly and stop afresh amid 8:48 and 8:57. After acceptance answer, restart the video to reinforce or absolute their ideas.
Ask students:
10. Conclude the video and end with a catechism for acceptance to investigate at home. The catechism appears at the absolute end of the video afterwards the credits, from 9:49-10:03. Whether or not you accept to stop on this slide, use the catechism as a alert for your chic discussion.
“What you’re action to do with your glowsticks is agnate to what a chemist does.”
Ask students:
11. With the advice of the teacher, administer one double-sided worksheet and two glowsticks per student.
The abecedary may accept to administer the booty home items at the end of your presentation or at adjournment at the end of the academy day, rather than during your visit.

For example, if a formula that incorporates the cell reference “C4” is copied to the following cell to the best, the reference will change to D4 . If the identical formula is copied down one cell, the reference will change to “C5” . The other type of reference is an Absolute Reference.
