Follow along with a Science Buddies parent who is using family STEM activities to keep her kids learning at home during the COVID-19 school shutdown. New posts every Monday, Wednesday, and Friday. Today's adventure... building a grasping robot hand out of household materials.
Nothing Normal Around Here
If this was a normal week, I'd be telling you all about how this is National Robotics Week (#RoboWeek), how awesome building robots is for kids of…

Stay up late, or get up really, really early to catch nature's annual fireworks display. Students and families can extend Perseids fun with a hands-on science exploration of parallax. How far away are the things we see in the sky?
By Kim Mullin
Each August, a much-anticipated nighttime show plays live in our skies: the Perseid meteor showers. This annual event offers you the year's best opportunity to see meteors streaking across the sky, so long as you are willing to be awake well…

Have you ever taken notes from the chalkboard during class and not noticed what was going on around you? Or have you ever been so focused on a task that you haven't seen other people around you? In both of these cases, you were paying attention, but you were seeing without seeing! This is called inattentional blindness and it's the topic that you will investigate in this human behavior science fair project. If you are interested in how the human brains perceives information, then this might…

Observing Nature Means a Little More Sanity
It's been exactly two weeks since school closed for us, and I've learned a lot about each of my family members,…

How many times have you seen a car without the appropriate permit (either a license plate or placard that hangs from the rearview mirror) parked in an accessible parking space reserved for people with disabilities? If you find this behavior upsetting, you might be interested in figuring out how to discourage "cheaters" who use these spaces to make a quick trip into the store. Is it enough to let them know someone might be watching?

Explore the logic of computer coding — no computer required!
Have you ever asked your student to give you directions, turn by turn, to get you home from a familiar landmark? It can be eye opening to hear how they might guide you, and you may or may not make it where you need to go! But the process of giving directions helps reiterate the steps involved in moving along a frequent path. Writing a computer program is similar in many ways. You need…

In this week's spotlight: a food science activity that may fit right in with any baking you have planned for the season. Are pies on your family's list of favorites or traditions this time of year? How do you like your crust? Does your mouth water for a flaky crust on a homemade pie? In this kitchen science experiment, families can explore the role of fats—and the temperature of the fat—on the texture of a pie crust. When you get ready to mix up a crust, do you take the…

Humans are bipedal, which means we walk using two legs. This gave humans an adaptive advantage during the evolution of humankind. Being bipedal gave humans additional speed, balance and flexibility used for walking, hunting or traveling long distances. However, we may have lost the ability to climb or swing in trees like other primates. How much faster can you go when you are bipedal? Have a race with your friends using two legs, and then four legs (use your arms as your 3rd and 4th legs).…

Did you know that people eat with their eyes as well as with their mouths? Food presentation—also called plating techniques or garnishing—makes food appear more appetizing. Checking out how the food looks is the cook's last task and the diner's first. Food that is well-presented is beautiful, colorful, and captivating. Not only does it make the diner really want to eat, but good presentation also allows the diner to identify the food ingredients, their quality, and the technique…

Explore the physics of friction using sticky notes.
What happens when you interleave the pages of two books or pads of paper? Why?
The friction between two objects determines how difficult it will be to slide one object across another. Friction accounts for how your feet move across grass, for example, compared to how an ice skate moves across ice. Scientists use both the coefficient of friction and measurement of normal force to talk about how much…
