Tip your feet so you’re standing on your heels, like a penguin. Put the “egg” on your feet. Now waddle like a penguin! How far can you go before dropping the “egg”?

What do garbage trucks do with garbage?2. What did this lesson make you curious about? What other questions do you have?Bonus Activity: The best way to deal with garbage is to throw less stuff away! Think about things that you use just once and then throw in the trash. Maybe you thought of plastic spoons, plastic water bottles, or plastic bags from the store. What else can you think of? How could you replace these throw-away items with things you can reuse instead? Make a list or draw a picture of the throw-away things. Be sure to include your ideas of what you could use to replace them! ps305grade4 https://padlet.com/ps305grade4/MYSTERYSCIENCE/wish/1151688162 2021-02-02 03:12:36 UTC https://padlet.com/ps305grade4/MYSTERYSCIENCE/wish/1151688162 1.

What equipment would you need to get to your chosen spot? What would you need to stay safe while you’re there? Describe or draw a picture of your ideas. ps305grade4 https://padlet.com/ps305grade4/MYSTERYSCIENCE/wish/1151690103 2021-02-02 03:13:57 UTC https://padlet.com/ps305grade4/MYSTERYSCIENCE/wish/1151690103 1. How were emojis created?2. What did this lesson make you curious about?

See how many emotions you can find in car “faces” around your neighborhood! ps305grade4 https://padlet.com/ps305grade4/MYSTERYSCIENCE/wish/1151691042 2021-02-02 03:14:31 UTC https://padlet.com/ps305grade4/MYSTERYSCIENCE/wish/1151691042 1. Who invented candy?2. What did this lesson make you curious about? What other questions do you have about candy?Bonus Activity: Candy is tasty, but it’s not perfect. Chocolate bars make a mess when they melt. Taffy sticks to your teeth. Life Savers stick together. Think like an inventor. What could you do to improve your favorite candy? Could you give it a better package or a new flavor? Could you make it less messy by putting it on a stick like a lollipop? Write or draw what your new candy would look like. Give your candy a name. ps305grade4 https://padlet.com/ps305grade4/MYSTERYSCIENCE/wish/1151692503 2021-02-02 03:15:29 UTC https://padlet.com/ps305grade4/MYSTERYSCIENCE/wish/1151692503 1.

Centipedes and millipedes have too many to count! What kind of “bug” do you think it is? You can keep a “bug” journal and make drawings of all the different kinds you find! ps305grade4 https://padlet.com/ps305grade4/MYSTERYSCIENCE/wish/1151695443 2021-02-02 03:17:30 UTC https://padlet.com/ps305grade4/MYSTERYSCIENCE/wish/1151695443 1.

If you like, make a plant journal with pictures of the different plants that you draw! ps305grade4 https://padlet.com/ps305grade4/MYSTERYSCIENCE/wish/1151729673 2021-02-02 03:40:15 UTC https://padlet.com/ps305grade4/MYSTERYSCIENCE/wish/1151729673 ps305grade4 https://padlet.com/ps305grade4/MYSTERYSCIENCE/wish/1310435543 1.
