5th Grade

Day 1
  1. Watch the video, "Chemistry Intro" by Mrs. Erickson.
  2. Watch the TedEd - The Law of Conservation of Mass by Todd Ramsey -   
**There is nothing to turn in this day, just watch both videos.  
 
Day 2 - 
  1.Watch TedEd - The Chemistry of Cookies by Stephanie Warren
  2. Watch the video, "Vinegar Blast" by Mrs. Erickson.
  3. Complete the activity - combine small amounts of baking soda and vinegar into ziplock bags and seal them quickly. Observe the gas you have trapped. Now try to determine how much material you need to make the bag "explode". You should get a good popping sound (generic bags work best). Take a picture or video to show your teacher. 
  4. You MUST turn in proof that you found the chemical equation for the reaction of baking soda and vinegar. (Write it down and turn in to your teacher). 
          *Turn in the chemical equation you discovered!
 
 
  5. Optional Bonus: Watch Sci Guys - Electrolysis of Water -
        **IF your parents give you permission AND agree to help you be safe, try this at home.
 
 
Day 3 - 
  1. Watch Science Max - Slime Full Episode - https://www.youtube.com/watch?v=Hx0FC0CDdVM
  2. Find a recipe for slime online - you may choose any one you would like - and make the slime.     
  3. Find the chemical equation for the slime you made. 
  4. Upload a picture to your teacher. *Be sure to include the chemical equation you discovered!
 
 
  5. Optional Bonus - SLIME CHALLENGE!! - Watch "Slime Challenge" by Mrs. Erickson
           Determine the best possible formula/recipe for the best possible slime in all of Redding.
              - Use this as a guide to design your experiment:
              - Use this as a possible link to a variety of slime recipes: 
 
6. Optional Bonus - Edible Slime - Watch "Gummy Bear Slime" by Mrs. Erickson
...please contact me via email. Most of the activities are fairly simple to explain with an email or quick phone call.
    (Don't forget to leave your phone number in the email. LOL.)
 
   Most of all, please have FUN doing these with your kids!

*This week we will be trying two Mystery Science lessons, when you follow the link, be sure to click on "I'm a Student" when prompted!
           *If you would like to print the worksheets, they are on your teacher's google classroom page under the science tab. If you do not want to print them, that is fine, write your answers on a blank sheet of paper or online, but you will need to use the worksheets to see the questions asked.  
 
Day 1 - 
  1. Watch the instructional Loom - Chemistry Unit 3 - https://www.loom.com/share/36d7d0f625394be68115a5147e603164
  2. Watch Science Max - Chemistry (the full episode) on YouTube. https://www.youtube.com/watch?v=z1HVILM5b_Y
  3. Answer the question: What new chemicals does Phil use to 'Max Out' the baking soda volcano?
        *Turn it in for your credit for today!
 
Day 2 -  
  1. Watch: Part 1 - Set-Up Directions - https://www.loom.com/share/6969e38d58814347a36788232a1d2294
  2. Follow the link to Mystery Science - Are Magic Potions Real?
  3. Watch the mystery and complete the activity - Test Like An Alchemist.
  • You will test salt water, soapy water, vinegar, and vinegar with salt to see which ones will clean the tarnish off a penny (a pre-1982 penny). Then, when one penny changes from dark and dirty to bright and shiny, you’ll have a chance to think about where the tarnish went. Soak the pennies overnight with a nail to see if you are right. 
  4. Before you stop for the day, be sure you are soaking your pennies and nail overnight!
     Watch the loom video I made so you do this correctly.
       *You do not need to turn anything in today as you will turn in the completed worksheets at the end of Part 2.
       *If you do not have the supplies needed, don't worry, you can still complete the work, it just won't be as fun. Watch the entire mystery and answer the questions. 
 
Day 3 - 
  1. Follow the link to Mystery Science - Could You Transform Something Worthless into Gold? 
  2. Watch the mystery and complete the activity, The King's Sword.
  • You will use one of the solutions from part 1 and several pennies to copper plate a steel nail. You will then create a written model of how the particles in the experiment move.
  3. Finish answering the questions you see on the worksheets and TURN THEM IN online to your teacher for credit. 
      **Note: For part 2, if you do not have a steel nail, you will still be able to complete the assignment. Watch the mystery from beginning to end and you will be able to answer all the questions. 
*Fourth grade,  go back and go to fourth grade, you have your own assignments now. 
 
The Four Spheres Wrap Up!
 
Day 1 - Review 
 
1. Watch the loom introduction: Convection Currents
    **DO NOT do the tea bag demonstration on your own unless you have your parent with you! 
 
2. Watch the videos and answer the three questions below:
  • Crash Course Kids: Four Spheres Part 1(Geo and Bio)
  • Crash Course Kids: Four Spheres Part 2 (Hydro and Atmo)
  • Heat Moves Matter - Fun Science Demos 
 
3. While watching the videos answer these three questions:
  1. What is a biome and which of the four spheres is it related to?
  2. What are the layers of the atmosphere? Which layer does weather occur in?
  3. What caused the crust of the earth to crack and form into plates? Why do they still move today?
 
Day 2 - Convection Currents and the Air
 
1. Watch the videos to understand how heating of the earth affects the entire atmosphere. 
  • Crash Course Kids: Up, Up and Away
  • Eco-Wise - Wind Currents and Weather Patterns
3. Build a solar updraft tower. 
         You may use any supplies you have and any design you find. However, I found these two and they seem to work well. The loom I made will show you how I made mine or you can use the websites if you prefer. 
 
 
Day 3 - Convection Currents in the Ocean
 
  1.Complete the density of salt water demonstration by following the procedure below and answering the questions at the end.
 
"Swimming Carrot"
     (Density of salt water demonstration): 
  1. Obtain two clear cups.
  2. Place a small piece of carrot (about 2in.) into the first cup. Note that it sinks.
  3. Add salt, one spoonful at a time, to the cup of water and stir it until it dissolves. 
  4. Record how many spoonfuls it took before the carrot floated.
  5. Place a small piece of potato (about the same size as the carrot) into the second cup. 
  6. Repeat steps 3 and 4 for the potato.
  7. Which object, the carrot or potato, required the most amount of salt to float? What was happening as the salt was added to the water? (Hint: it has to do with density). 
  8. If you were swimming, would it be easier to stay afloat in a lake or in the ocean? Why?
  9. Which is more dense, salt water or fresh water?
2. Watch these videos on the currents in the ocean and answer this question: 
             What are the causes of the ocean currents? (There is more than one! Find at least three.)
  • TedEd - How do ocean currents work?
  • Crash Course Kids - Current Events
 
Your assignment for this week is to make a 3-D model of the planet you have chosen for your report in Mr. Potter's ELA. Please make sure your colors are accurate but use any materials you have access to. 
 **If you do a good job and are willing to give your model up, I would love to hang them in the classroom!
It is my understanding that many of you are behind on your science. So, if you are behind, use the next two weeks to catch up and complete all of the science lessons that you are missing.
 
For those who have kept up, we are going to spend the next two weeks doing some STEM challenges. Each week, pick one challenge (or as many as you would like), complete it and upload videos to your teacher. 
 
**WATCH THIS FIRST!!!***
 
STEM Challenge Week Ideas:
 
Idea #1. LEGO Challenge:
 
Idea #2. Build a self-propelled car.
I made these two instructional videos for third grade simple machines unit. The first shows you how to make a wheel and axle that actually turns and gives ideas on supplies you can use from your recycle bin. The second is how to make a balloon powered car. 
 
 
Idea #3. Build a self-propelled boat that actually floats.
 
Idea #4. Make s'mores in your own solar oven. 
 
Idea #5. Make a marble run - go life-size if you can!
These aren't life size but just ideas of different ways to make them. 
 
Idea #6. Pool Noodle and Toothpick Structure
Cut a pool noodle into pieces of varying size. Build a structure - either as tall as you can and/or as stable as you can. Test your structure in water to make sure it floats.
