STEAM Takes On… Catapults
Catapults are projectiles. They thrust objects across distances. Objects go farther depending on their weight and the amount of force used on them. Catapult have been used throughout history to launch things from one place to another.
Want to see how to build your catapult? Watch the video below!
From your activity kit, you will use:
9 popsicle sticks
1 bottlecap stick
5 rubber bands
Put 7 sticks in a stack and wrap a rubber band around each end. Wrap a rubber band around the two remaining sticks. Pull the two sticks apart. Slide the stack to the bottom of your two sticks. Make an X around the bottom with your rubber band to hold your stack in place.  Wrap a rubber band around your top stick. Slide your bottlecap stick under the rubber band. Your catapult is done! Test it out with your fuzzballs!
Does changing the length of the arm change the distance your object is launched? Since size and weight make a difference in distance, try different items! You can also use a plastic (or real, with permission) spoon. Does your object launch farther with the spoon(s)?
STEAM Takes On… Growing Plants
From your activity kit, you will use: pot, soil, and seeds.
Fill your pot with soil. Wet pot and soil thoroughly with warm water. Using a pencil, make 2 small depressions in the soil in the middle of your pot. Put two seeds in each depression. Cover seeds with soil.
Keep your pot in a warm, well-ventilated location. Never let your soil dry out. Within 10-14 days, you will start to see a sprout! As your flower grows, you will want to switch it to a larger pot or put it in a sunny spot outside.
These seeds can also be planted directly into the ground.
STEAM Takes On… Dino Skeletons
Have you ever thought about what a dinosaur's skeleton may look like? It's fascinating to see how their bones work together to allow for movement, size, and other dinosaur traits.

From your activity kit, you will need: glue, q-tips, and dino template. You will also need pencil and scissors. Sketch out your dinosaur skeleton. Cut your q-tips to size. Glue your q-tips on to your skeleton. You have a dinosaur!
Check out these google links for help sketching out your skeleton. Click images under the search bar to see the results. Find the one that helps you most to use as a guide.

STEAM Takes On... Marshmallow Pyramid
This week, STEAM Takes On... marshmallow pyramids. Building something out of marshmallows and toothpicks can be really fun! It doesn't have to be a pyramid. You can make a tower, a house, or even a geodesic dome.

STEAM Takes On... DIY Bird Feeder
This week we venture into the woods and STEAM Takes On... DIY Bird Feeder.
From your activity kit, you will need: paper plate, paper plate holder, three pieces of string, and bird seed.
Tie strings to the ridges around the paper plate holder. Slide your paper plate under the ridges. Take your bird feeder outside to where you want to hang it. Trees are great. Slide it on to the branch and tie the strings together so it hangs evenly. Pour some of your bird seed onto. Your bird feeder is done! Now is your chance to observe your neighborhood birds.
Find out more about the birds you see from Cornell Lab of Orinthology at birds.cornell.edu
STEAM Takes On... Lemon Volcano
This week we explore the magic of chemistry. What happens when you combine an acid (citric acid found in lemon) with a base (baking soda)? This chemical reaction is bubbly and the fun goes on for a while! Plus, unlike other volcano projects, it smells great!
From your activity kit, you will need: craft stick, lemon, and baking soda. You will also need a plate, food coloring, and dish soap,
Cut your lemon in half.* Then, cut a small piece off the end so it will sit flat on your plate.* Loosen the inside using your craft stick. Add food coloring to the middle of your lemon. Add dish soap to the middle of your lemon. Add baking soda to the middle of your lemon. Your lemon will begin to fizz. Use your craft stick to mix the baking soda with the lemon juice. Add more baking soda and food coloring to keep going.
