The last few weeks of school seem to go on forever, don’t they? And then there are the last-minute projects . . . I hope today’s tutorial to DIY a model of an atom will help ease the pain! When you hear “mom, I’ve got a science project due tomorrow”, Crafts ‘n Coffee has you covered! Thank you to Linda Valentino for today’s tutorial on how make a Lithium Atom with balls of STYROFOAM™ Brand Foam. (Need more ideas? Check out the DNA Model, Animal Cell Model, Plant Cell Model and Solar System models, too.)
To make a model of a Lithium Atom, you’ll need:
- STYROFOAM™ Brand Foam: Six, 1-1/2” balls and three, 1” balls
- Metal rings, two
- Wire, 26-gauge in silver
- Monofilament (clear) nylon thread
- Acrylic craft paint in red, blue and yellow
- Straight pins
- Thick, white craft glue
- Tools needed: Scissors; plastic knife; paintbrush
To make a model of a Lithium Atom:
1. Push one ring into the other and center. Wrap wire around joints until secure. Squeeze glue onto wire, and let dry.
2. Insert toothpicks into the foam balls, and use the toothpicks as handles. Paint the balls:
- 1” balls red
- Three 1-½” balls blue
- Three 1 ½” balls yellow
3. Build the nucleus:
- Dip both ends of a toothpick in glue.
- Insert one end in a yellow ball and the other end in a blue ball.
- Tie a 15” length of nylon thread around the exposed toothpick between the two balls, leaving one end as long as possible.
- Trim off the shorter end, and dot knot with glue.
- Repeat, making a second pair of blue and yellow balls.
- Using toothpicks and glue, join together the two pairs of blue and yellow balls to form a group of four. Position the balls so that the nylon threads are on opposite sides.
- Insert one end of a toothpick dipped in glue into the last yellow ball.
- Push the toothpick through the group of four balls, and add the last blue ball on the other end.
4. Add the electrons:
- Using the plastic knife, carefully cut the red balls in half.
- Center two pairs on one metal ring, and glue the halves together.
- Center the last pair on the second ring, and glue the halves together.
5. Center the nucleus in the middle of the rings. Tie one nylon thread to the top, and the other to the bottom. Trim off ends, and add a dab of glue on each knot.
6. Optional: If you’re going to hang your model, loop nylon thread through a ring for a hanger.
It’s been years (decades!) since I’ve had a science class, and I had to look up Lithium to find out more about it. Turns out it’s the lightest metal and the least dense, solid element, but it sure has powerful properties!
About four more weeks till school is over . . . How’s the school year going in your house or your neighborhood? When is the last day?
I also have the winners of the three, $25 gift cards. Thank you to everyone who shared their crafts. I love reading about what you’re making! The winners are Katiria, Debbie Kaste and Yolanda. Please contact me for the details, ladies.
