STEM Challenge for Summer with Buoyancy - Design a Submersible

STEM Challenge for Summer: Design a Submersible!

This is one of the more challenge STEM activities I have done with kids over the years! It's also perfect for summer because you will get wet!

Warning: You WILL Get Wet with this STEM Challenge

Why try this challenge? I can't even tell you how many boat challenges I have done with kids, asking for a simple craft that floats, something that can be propelled with wind (sailboat), and so on.

You have probably also done "Does it sink or float?" activities with your students over the years.

This challenge is a combination of all those!

What if we want an object to not sink,

but to float,

but not at the surface and rather about halfway between the bottom of a body of water and the top?

Gather Materials for Submersible STEM

First, gather all materials needed for the challenge:

For the water:

You will need a tub, storage bin, kiddie pool, etc. for this challenge. You will also need to fill the bin with water.

Students can create their submersibles with aluminum foil, popsicle sticks, plastic egg carton pieces, balloons, rubber bands, recyclables, pennies or small weights, etc.

Your students can start in one of two ways:

• With an object that floats, that they will need to make LESS buoyant.
  
• With an object that sinks, that they will need to make MORE buoyant.
  

Go Deeper with Science in this STEM Challenge

Have your students research density and buoyancy. Ask:

How does the density of an object affect its buoyancy?

When might you want a water vessel to NOT be completely buoyant?

What skills do students work on? In addition to following the Engineering Design Process to complete this challenge, students will need to work together and may need to make several modifications to improve their sail designs.

Christmas STEM and STEAM Activities

Christmas STEM Activities for Kids

Ho, ho, ho! Try out these Christmas STEM activities this holiday season to keep students engaged all the way until holiday break. I have created twelve fun AND differentiated STEM and STEAM activities that range from simple towers to moving conveyors!

Get started with Christmas STEM

Jump right in with peppermint candy and have students create either a tower or a bridge. Don't forget to follow the engineering design process! While you don't need to spend a lot of time on each step, it is important to follow the process. Kids will want to start building right away! One way to avoid this is to hold off on building material distribution until after a design sketch has been completed.

Then move on to a gingerbread house! If you are working with upper elementary or middle school kids, create the house with cardboard and have them add a simple circuit to light up their house.

STEM Strength Challenge - Support the Weight of the Stocking Goodies!

An empty stocking is not that difficult to support, but what about all of the goodies Santa leaves? Students will need to design a counterbalance system to keep the stocking from falling. This is a great activity to practice the testing phase of an engineering design challenge. It's also important to make sure that your testing set-up is safe so that no toes are injured when the stockings inevitably fall!

Do You Hear What I Hear?

Design and create a jingle bell for Christmas! Use metal objects to create a jingling bell.

Once the bell design is complete, change up the challenge by having students create a way to silence the jingle bell.

Help the Elves in the Workshop

Moving gifts around in the workshop is no easy task! Help the elves by designing and creating a conveyor belt! This challenge is perfect for showing how rotational motion can be converted into translational motion.

Find these and more activities in the 12 Christmas STEM Challenges Activity pack! Not only will you find more detailed instructions for the above challenges, but each challenge comes with a colorful poster and engineering design recording page!

Winter STEM Challenge with Frosty the Snowman

STEM Activities for Frosty the Snowman 

STEM That is Easy to Implement

This story is one of my favorites of the "Pick Your Path STEMventure" series. This story is about beloved Frosty, and helping to make his day the BEST.DAY.EVER. Students decide how they want the story to progress; in completing the story students will complete 3-4 challenges. The story not only guides students through the engineering design process, it includes design constraints and areas for them to fill in their thoughts, plans, and testing data. However, you don't need the resource in order to do just the building parts. Read on to find some fun and creative STEM activities you can do to make Frosty the snowman have a great day!

If you do use the resource I created, students will read through a story about Frosty, and then choose where they would like him to go. Depending on their choice, they will encounter different STEM challenges along the way.

Sled STEM Challenge 

Sleds are an excellent tool to teach students about force and motion, potential and kinetic energy, and friction. Can your students design and create a sled that Frosty can fit in and use? You could use a mini figure or paper Frosty as shown:

Race sleds down a cardboard box on a slope, or use a large sheet of plastic cardboard (find at your local hardware store). It makes a great snow hill! Try different materials to see which ones travel best downhill. Shown are legos, and a section of plastic egg carton covered with vinyl tablecloth.

An Unlikely Winter STEM Challenge - Hammock

Why would Frosty need a hammock? Well, you'd have to read the story to find out. This is a simple challenge that kids always love. Who doesn't love relaxing in a hammock?

Do you want to build a snow-less snowman?

There are several other challenges you can do with a snowman, including building one (use baking soda to make inexpensive fake snow). Students can challenge themselves to build a regular snowman and one that is upside down, as well! For older students, have them hypothesize the correct ratio of baking soda to water to make "snow" that sticks together and holds a shape. They can then test it out and create a recipe, then build their snowmen.

Bird Beak STEM - Animal Adaptations STEM Adventure

STEM Activities for Elementary Students to explore Bird Beaks and Pollination

STEM That is Easy to Implement

This is the fifth installment of the "Pick the Path STEMventure" series. This story is about a budding ornithologist, Beth, as she visits a nature sanctuary and learns about various birds. Students decide how they want the story to progress; in completing the story students will complete 3-4 challenges. The story not only guides them through the engineering design process, it includes design constraints and areas for them to fill in their thoughts, plans, and testing data.

If you are studying animal adaptations, pollination, or even ecosystems, these are some engaging hands-on activities that your students will enjoy exploring!

Pollination STEM Challenge 

Pollination is a concept that can be difficult for kids to understand. In this challenge, they will transfer "pollen" (which can be chalk dust, flour, etc.) from one flower to another.

A bonus in the resource I created is a page all about pollination. Students learn the basics and can color in the flower diagram to get a better idea of how plant reproduction takes place.

Another Bird Themed STEM Challenge - Eating

Do you know how hummingbirds eat? They don't use their long beak like a straw, but use their tongues to lap up nectar much like a dog does. In this challenge, kids will have to try to grab the food at the bottom of a tube. They will be glad this isn't a requirement for their own meals because it's harder than it looks! The food can be anything that can be picked up, but I use pompoms. In addition to grabbing the item (such as with chopsticks), students can "hook" onto the food. If you are learning about magnets, you could absolutely work this in. Have the magnet be the food, and students will need to use an item in their "tongue" that is attracted to magnets in order to pick up the food.

My favorite challenge in this story explores wading birds and different types of beaks. Can you pick up the food but allow the water to drain out? Can you stab the food?

There are other types of bird beaks to explore as well, and this is a great time to talk about the food chain, the environment, and being a good Earth citizen. What would happen if a bird's food supply goes away? Would they be able to adapt? Would their beak work well to eat another kind of food? These are big questions but I find most kids are ready to tackle them.

Beginning Circuits Activities for Kids that are Easy to Implement!

Paper Circuit fun with Chibi Lights

I just adore Snap Circuits, but occasionally it's nice to keep a project together to take home or create something, like a card, to send to someone else. In these cases, paper circuits are a great option!

Disclaimer: Please note that Chibitronics did send me kits to review, but the opinions expressed are completely my own. I may earn a small commission for my endorsement, recommendation, testimonial, and/or link to any products or services from this website. Your purchase helps support my work in bringing you downloads of value and information about educational resources. The links below are Amazon affiliate links. You can read my full disclosure here.

What is the Chibi Lights Kit good for?

I think this kit is best suited for a holiday or birthday gift. It is a great way to encourage a child who is either crafty or interested in circuits (or both!). This is also a good option for Makerspaces that host afterschool or weekend enrichment classes, provided they can charge enough to cover the cost. It would be a great activity near the holidays to create a special card or display as a gift.

What is the Chibi Lights Kit NOT good for?

A classroom setting, unless you have been awarded a grant and have a special project in mind (or if you can charge a fee). It would be too costly otherwise.

 Things we liked about the Chibitronics Sticker Circuit Kit

• Easy to read, learn, and use. After unpacking the box, we had built our first circuit within minutes. You can't get much easier than that for implementation!
• The booklet includes fun activities that are engaging for kids. It also includes thorough and useful background information needed to understand and complete the projects.
• All of the components that are needed for the basic projects are provided.

A few things we thought could be better:

• Two times, we thought we made our circuit wrong because it wasn't working quite right. Unfortunately as is sometimes the case with electrical components, the LEDs were just not good. This happens with regular (large) LEDs too sometimes, but we wonder if it happens more often with the tiny LEDs. Switching out the LEDs proved that that was the issue but it was a little hard to debug. It's also possible we got a bad batch.
• The copper tape tears really easily. That is why I am recommending this for ages 10+ unless you have a very careful child.
• The one-time use factor. We knew this going in, but it would be nice to at least reuse the LEDs somehow. 

All in all, I think this is a great kit to expose kids to circuits. The guidebook/sketchbook was much better than I was expecting and is very much worth it for the educational component. The kids get excited when they see their circuit working!

Simple STEM with Plastic Cups

Plastic Cup STEM Challenges Your Kids will Love

Spoiler alert - there is no basic tower challenge in this list. Building towers is a great way to start off any cup STEM challenge, but I have a list of a few some fun and engaging challenges using primarily plastic cups. Some are oldies but goodies, and others you may not have seen or tried before.

Get Started with Plastic Cup STEM - Materials

Although you can use inexpensive plastic cups for these challenges, I recommend using a sturdy variety. You do not need to get the brand name, most expensive cups, though. I used my local grocery store's version of a heavy duty brand name cup.

Create a Plastic Cup Telephone

A really easy challenge to get started with is a plastic cup telephone. Many kids will have done this before, however try to supply them with a variety of string and/or wire types for the line, and have them test out different versions to see which works best.

Make it easier for little ones: Have a variety of telephones already put together. Use different string types or different lengths of string and have them try to speak messages to each other. Make sure the line is pulled tight for best results.

Another Sound Challenge - Create a Plastic Cup Sound Amplifier (shown above, top)

Smartphone speakers just not loud enough to share your favorite jams with your students? Have them create a sound amplifier! Not only is this a really great hands-on STEM activity to explore sound principles, it is actually useful. The roller, also shown above is included in the plastic cup STEM challenge pack I have linked below. It is simple but includes a hands-on way to explore torque and friction.

Plastic Cup Anemometer

This one is a bit tricky but the result is absolutely worth it. Create your very own anemometer to measure wind speed. Use five cups, some towels, and tape or a push pin and you can create an anemometer!

Try These STEM Challenges with the Engineering Design Process

If you want to add more rigor to these challenges by following the engineering design process, please visit the following resource I put together to support these plastic cup STEM challenges. With this  guided STEM resource, students need to meet the design criteria specified to complete the challenge. Add it to your STEM Friday or Maker Monday rotation, or save it for a sub.

St. Patrick's Day STEM with a Leprechaun

Fun STEM Activities for Elementary Students on St. Patrick's Day

STEM That is Easy to Implement

This is the fourth installment of the "Pick the Path STEMventure" series. I wrote a short story about a leprechaun called Larry for St. Patrick's Day. No, we are not trapping the leprechaun! That has been done enough. In the story, Larry the leprechaun gets the opportunity to earn gold coins on St. Patrick's day by successfully completing various STEM challenges. Students choose how they want the story to progress; in completing the story students will complete 3-4 challenges. The story not only guides them through the engineering design process, it includes design constraints and areas for them to fill in their thoughts, plans, and testing data.

A Few of the Challenges Included 

Up first, is a rainbow challenge. If you are studying light, this is a great time to do this challenge. In addition to the stories requiring students to design and test structures, they will be exposed to various science and technology concepts, such as dimensional constraints, malware, and the color spectrum.

Another St. Patrick's Day STEM Challenge - Unplugged Coding

Not all kids love coding, but it is still great to expose them to simple logic problems that are the basis of coding. Creating a path is a simple way to have kids think ahead and plan out a set of directions.

This challenge has two versions, plus I included extension options in the digital download for additional challenges. The other challenges include:

• a slide
• a musical instrument
• a bank that holds gold coins
• two bonus challenges, including a gold coin flipping device!

You can do several of the challenges mentioned above (aside from the coding one) without the resource I created, though if you would like it for the story and guided design process, keep reading. Here is an example of the slide challenge:

Popsicle Stick STEM Challenges - Fun Craft Stick Activities for Kids

Craft Stick STEM Challenges Your Kids will Love

Whether you call them popsicle sticks, craft sticks, tongue depressors, or paddlepop sticks, you are probably familiar with a number of ways to use this versatile material.
 

Get Started with Popsicle Stick STEM

Disclaimer: I may earn a small commission for my endorsement, recommendation, testimonial, and/or link to any products or services from this website. Your purchase helps support my work in bringing you downloads of value and information about educational resources. The links below are Amazon affiliate links. You can read my full disclosure here.
 
You can use standard popsicle sticks, but I find them much more challenging to work with than large, 6" x 3/4" sticks. Make sure you sort through them and remove any that are broken, split, or have splintering edges. If you are looking for jumbo colorful ones like the ones above, I got mine here.

Create a Popsicle Stick Bridge

A really easy challenge to get started with is to create a popsicle stick bridge. Use binder clips to hold the sticks together and make it easily reconfigurable. You can create a simple ladder style design or try something a little more funky. Get creative and see what works! For older kids, you can use hot glue to create some really intricate and large bridges with a long span.

Make it easier for little ones:Binder clips can be hard to work for small fingers. Attach Velcro/hook & loop stickers to the ends of craft sticks for easy building. In addition to bridges, they can use the sticks to create 2D shapes and even letters.

Create a Stick Bomb Chain Reaction 

This one will entice even reluctant kids to get in on the STEM action! Use a weaving technique to apply tension to the sticks. You can work with a variety of patterns, from simple to the more complex. For very simple designs, visit this YouTube channel
as he has some great tutorials (tip - watch at .75 speed because he talks really quickly!). Or you can try to create a pattern like the one below - just search "stick bomb" on YouTube and you'll find a variety of videos explaining how to weave it. I recommend working on a carpet if possible because it's easier to slide the sticks into place.

Popsicle Stick Marble Maze STEM

This one is a bit tricky but SO much fun! Create a marble maze in a box. If you are working with your own kid(s), you can use a box cutter to poke the sticks through the cardboard to secure them. Otherwise, duct tape works well. Pro tip: tilt the box back slightly to help keep the marble from falling out, or construct "channels" by making an L-shape with two sticks.

Other Craft Stick STEM Ideas

Craft Stick Art or Bow and Arrow

If you want to get really creative, you can soak them in water for a few hours or overnight, and then bend to the desired shape. This is a lot of fun, but takes some careful planning ahead. You'll need to then clamp the sticks in place somehow until they dry. There are some amazing designs you can create!

Craft Stick Harmonica or Kazoo

Use craft sticks in your STEM station!
