It’s been a busy summer, but we’re working on some sweet new experiments to share with you soon!
Last week, the kids and I got an advance copy of my new book “Kitchen Science Lab for Kids,” which will be available September 15th and we love how it turned out!
If you pre-order a copy from Amazon, Barnes&Noble, IndieBound, or Indigo before August 15th, I’ll send you a personalized, signed bookplate for each copy you order. Just email your receipt number and the address where you’d like the bookplate(s) sent. My email address is firstname.lastname@example.org. (Be sure to include the name(s) you’d like the book signed for!)
At-home science provides an environment for freedom, creativity and invention that’s not always possible in a school setting. In your own kitchen, it’s simple, inexpensive, and fun to whip up a number of amazing science experiments using everyday ingredients. Science can be as easy as baking. Hands-On Family: Kitchen Science Lab for Kids offers 52 fun science activities for families to do together. The experiments can be used as individual projects, for parties, or as educational activities groups. Kitchen Science Lab for Kids will tempt families to cook up some physics, chemistry and biology in their own kitchens and back yards. Many of the experiments are safe enough for toddlers and exciting enough for older kids, so families can discover the joy of science together.
Can kids in middle school come up with world-changing inventions? Absolutely.
Most 5-8th graders don’t have free access to labs full of chemicals and equipment, which is probably a good thing, but they’re armed with more curiosity and creativity than most adults. When given the opportunity and encouragement to let their imaginations run wild, kids come up with the most amazing ideas.
The Discovery Education 3M Young Scientist Challenge helps address the gap between idea and reality, and offers kids amazing incentives to come up with big ideas. The competition encourages kids in middle school to make two-minute videos about their ideas for using science, technology, math and engineering (STEM) to solve real-life problems. The videos are judged based on
- Creativity (ingenuity and innovative thinking) (30%);
- Scientific knowledge (30%);
- Persuasiveness and effective communication (20%); and
- Overall presentation (20%).
3M‘s Innovation Page gives overviews of how their scientists are impacting our daily lives, and some of their scientists will mentor the contest’s ten finalists, helping them envision how to take their creations from dream to reality. Ten finalists will travel to the 3M Innovation Center for the final competition.

It seemed like the best way to learn about how kids come up with ideas was to ask my own two middle schoolers if they’d like to enter the contest, so I asked them to think about problems that they could help solve with STEM. They were less than excited until I showed them a few of the videos from the Young Scientist Challenge website. Like me, they were blown away by what Peyton Robertson and Deepika Kurup created to win the 2012 and 2013 Young Scientist Challenge and decided, without any prodding from me, that they wanted to come up with their own ideas.
My son, who is a voracious reader of all things science, and is somewhat obsessed with meteorology, immediately knew what particular area he wanted to focus on. It took a few days, but now he’s got a great idea and is working to make a model to test.
My oldest daughter was another story. She likes science, but spends much more time thinking about acting, basketball, photography, her friends, and our German Wirehaired Pointer. She quickly got frustrated and worried that she didn’t know enough about science to come up with a good idea. To encourage her, I asked her to think about how she could solve a health problem in animals, prevent basketball injuries, make a camera app, or solve an environmental problem. She decided to try to think of something people throw away and use it for something really great. While researching ocean trash, she came up with another idea, addressing a water pollution problem and is excited to test out her idea.
They need to get going, since the entry deadline is April 22nd, but I know they can do it, and love the ideas they’ve come up with!
If you’re on Twitter, you can follow the contest @DE3MYSC and join us for #STEMchat on Twitter April 8 from 9 – 10 PM Eastern as we talk about How to Raise America’s Top Young Scientist (this is the title earned by the winner of the DE 3M YSChallenge.)
Although I don’t usually write sponsored posts, I made an exception for this contest, since I think it’s a fantastic way to get kids excited about STEM. This post is sponsored by the Discovery Education 3M Young Scientist Challenge.
How would you safely land a spacecraft on a planet with no atmosphere if you couldn’t use rockets? A parachute wouldn’t work, since there’s no air resistance. You’d have to design your craft with a protective shell so the impact wouldn’t destroy it.
Pretend a raw egg is your spacecraft and Voila: you have a science experiment. Besides being lots of fun, an egg drop experiment is a great way to try your hand at engineering and is a fantastic STEM (Science, Technology, Engineering and Math) project for kids and adults alike!
The kids and I dropped holiday decoration-encased eggs from a crane in the Kare11 studio on Kare11′s Sunrise News to test our own engineering skill. Click here to see what happened.
The law of motion says that the faster you change the speed of an object, the greater the force applied to the object will be. We demonstrated this concept with our egg-throwing experiment by smashing eggs against a table, which stopped them fast, and watching them survive being hurled against a hanging sheet, which slowed them down. This same law explains why, if you drop an egg on the floor, it will break. When you change the speed of the egg slowly,by suspending it or surrounding it with material that helps absorb or redirect the force, less force is applied to the egg and it may remain intact. Can you design a container to protect an egg?
Why not have a holiday egg drop competition with your out-of town cousins, or other friends and family? Here are the rules we came up with. (We have a no parachute rule, but if you’d really like to design a parachute for your egg, that would be fun too!) I’m thinking an egg nogg carton might be a good place to start.
-Container made up of 100% holiday material like wrapping paper, bows, cardboard, tinsel, food, glue, toothpicks, wood, tape, plastic and string. No Styrofoam, bubble wrap or packing peanuts are allowed.
-Container must contain one RAW egg.
-No Parachutes (defined as any material attached to your egg craft in such a way that it will expand outward as it falls, catching air.)
-Container should be no larger than 20 inches in any direction
-No tape or glue must touch the egg.
Drop your egg from different heights to see how well it survives. (Make sure you’re supervised by an adult when you do your egg drop!)
You can calculate the force of gravity on your egg and container by multiplying its weight in kilograms by 9.8meters/second (the acceleration due to gravity.
If you live in the Twin Cities, I’ll be on Kare11 Sunrise on Tuesday morning Dec.18th with Kim and Tim. We’ll be dropping our containers from a studio crane. Should be fun!
Carin Bonder recently wrote a great post for Scientific American’s PsiVid about an autistic boy named Jordan Hilkowitz who is storming YouTube with his fantastic science videos! Parents will enjoy Carin’s post, and kids will love his Doctor Mad Science videos!
If you’re on Twitter, we’ll be chatting about STEM (Science, Technology, Engineering and Math) tonight at 8 Central under the hashtag #STEMchat. Click here for more information if you’re interested in joining us as we talk about kids science at home and in schools.
