In the spirit of Halloween, here is an example of a ~spooky~ STEAM activity called Ghost Rockets!
In case you forgot what the learning cycle looks like, here is a quick 3 minute video explaining the learning cycle:
Here is the learning cycle following the ghost rocket demo:
- Attention getting
- Creates interest in the topic
- Chemical reactions
- Throughout this demonstration, ask questions such as:
- What do you think will happen when I add the alka-seltzer?
- Why does it help that the film canister is so small?
- What allowed the film canister to fly up in the air?
- Give the students different materials to work with, and see which lab group can come up with the strongest reaction that gets the film canister to go the highest in the air.
- The provided materials that the students have to work with:
- Water, Sprite, Vinegar, Lemon Juice, Soda Water
- Mentos, Baking Soda, Pop Rocks, Toothpaste
- Have them write down any observations in their journals
- As lab groups, have them come up with their own definition of what a chemical reaction is and what the characteristics of a chemical reaction are
- Explain what they found/ didn’t find in the “explore”
- Share their results/observations with the class
- Ex. was there a color change? did the reaction release a gas?
- To apply the concept of chemical reactions, the students (as lab groups) would be assigned to create a presentation on a specific chemical reaction of their choice
- It can be the reaction they did in the explore, or another one that they researched
- The presentation would include a demonstration (that I have approved) of their chemical reaction, followed by a 4-5 slide powerpoint presentation explaining the chemistry behind their demo
- To assess their level of understanding, I would have each group collaborate and write down which presentation of all of the groups (not including their own) they thought demonstrated/explained chemical reactions the best.
- I would then have each group write down two things they liked and two suggestions they have for every group.
How do you get the attention of the entire classroom in just two minutes, and create a whole days worth of discussion, especially about a STEM activity??
Easy! Use the 5E learning cycle to gain interest in STEM fields!#EDT431 #scienceteaching @AnnMacKenzie #STEM
