After you have memorized all your multiplication and division facts, then you are ready for long division! This procedural allows you to divide really large numbers. Here is an example of what you will be doing:
You can remember these steps by:
Divide the first digit by the divisor
Multiply the divisor by the answer in the first column
Subtract the product from the divisor
Bring down the next digit and repeat.
You can solve these videos to practice this strategy.
Getting clean drinking water is one of the most important things we do as a country. Many STEM activities (like this one from Teach Engineering) encourage you to work in teams. If you can’t work in teams, these steps make it possible for you to do this activity at home with common materials:
If you want to play the first fraction game, it is here. You have been mastering this game!
Click “Build a fraction” and do 5 levels worth of fraction building.
Click “Mixed numbers” and complete 5 levels of mixed numbers.
New Fraction Game! Fraction Matcher requires you to match the fractions in 2 categories. You place them on the scale to check that they are the same. You goals (should you choose to accept this mission) could be:
Click “Fractions” and then complete 7 levels of matching fractions.
Click “Mixed Numbers” and then complete 6 levels of matching mixed numbers.
This fraction equality lab is another good one for seeing when 2 fractions are equal to each other.
The U.S. Geological Survey’s Hawaiian Volcano Observatory (HVO) recorded a magnitude-4.4 earthquake located beneath Kīlauea Volcano’s south flank on Sunday, December 20, at 10:36 p.m. HST.
The earthquake was centered about 14 km (8.7 miles) south of Fern Forest, near the Hōlei Pali area of Hawai‘i Volcanoes National Park at a depth of 6 km (4 miles). A map showing its location is posted on the HVO website at http://volcanoes.usgs.gov/hvo/earthquakes/. More details are available at the National Earthquake Information Center website at https://earthquake.usgs.gov/earthquakes/eventpage/hv72294777/
Weak to light shaking, with maximum Intensity of IV, has been reported across the Island of Hawai‘i. At that intensity, significant damage to buildings or structures is not expected. The USGS “Did you feel it?” service (http://earthquake.usgs.gov/dyfi/) received over 500 felt reports within the first hour of the earthquake.
Why did this video talk about volume? What volumes are important for volcanoes?

Do you trust the evidence in this video? Why or why not?

December 21 Volcano Update
December 23 Update
The volcano is now filling up the caldera (the hollowed out top of a volcano). There are some cool volume ideas here. Note that they discuss “cubic feet” and “gallons”. These are two measurements of space that you can see easily around you. (How could you make a 1 cubic foot space?)
Christmas Update
Volcanoes don’t stop on holidays! The lava lake is now 44 stories tall! Check out this cool page from the U.S. Geologic Service that shows cool pictures and a slider:
The recent update does a good job showing what has changed. I was most surprised by the rocky island floating in the middle of the lava pool. I hadn’t heard of that before!
December 27 Update and Video STEM Lab
The lava dropped 7 feet today! (Listen closely to figure out why.) I thought it was interesting that the lava fountains are spraying 32 feet into the air. That’s like throwing a football over a house but instead of a football it’s a molten boulder!
This lab may not have the coolest beginning but the set up is interesting and the result is very cool.
They say it’s “active”, but it’s more lazy these days!
Overview of Kilauea
A short video explaining the 2018 Kilauea lava outpouring. The end of the video talks about their “Volcano Day” thought experiment which is their make-believe way of getting people to pay attention to volcanoes.
This TV show highlights the people that study and document the volcano. It’s cool because they get right up to the lava, and the way they work with the lava helps us understand what lava really is. (Big idea question: Why is it called “living Earth”?)
This shorter video from the Smithsonian Channel shows how the lava is created and moves deep within this volcano.
Although we think of tall volcanoes, the lower rift area of Hawaii reminds us that the lava finds many ways to create new land on the surface.
This week we are going to focus on different perspectives of the founding of Virginia as a colony in 1607. Here are some resources we will use to explore these perspectives.
This cloud presentation might be cool for some, but I am betting you can do it better. Check out this information. There are great pictures (and weird owls).
Create a slide deck with pictures, sentences, and maybe even tables or lists with the info. Make it cooler! You can use Google Slides and send us the link or create a PowerPoint and upload the file below.
This video is from an expert at the Weather Channel describes weather maps and how weather works. All in 4 minutes! If you do not know any of these words, write them on a piece of paper and we can talk about them this week.
