Can you make color-changing paint from a simple cabbage? No doubt, sauerkraut. This activity from the scientists behind our BioTinkering Lab brings together biology, chemistry and art for an experience that is all science, and a little bit of magic.

The cabbage inks activity was made possible by a Science Education Partnership Award (SEPA), Grant Number R25 GM129220, from the National Institutes of Health (NIH).

Extract: 1½ hours
Mix & make colors: 30 min
Dry: 1-3 days
Create: 30 min

Subject: Biodesign, Chemistry, Art

Build a structure to take on an earthquake. Our latest activity sizes up your seismic safety. You’ll make a simple shake table and then construct a building that can withstand your shakes, rattles and rolls. 

Duration: DIY Shake Table: 5-30 min
Earthquake-Safe Structure: 45+ min

Subject: Engineering Design Challenge

Do you enjoy playing board games? Ever wanted to create your own? Use computational thinking to break down the process into simpler steps and design a unique game!

Duration: 30+ minutes

Subject: Computational thinking

Ever seen those wacky waving tube dudes outside a car dealership or furniture store? Imagine a DIY version!

Duration: 30+ minutes

Subject: Design Thinking, Engineering

Ever wanted to grow your own paper or plastic? Or create leather that doesn’t use animals? All these can be done at home by collaborating with microbes — tiny microscopic organisms — to grow a custom biomaterial.

Duration: 30+ minutes to create; one week to grow

Subject: Biodesign

Create the tallest structure you can with just five pieces of paper! This fun building challenge is great for multiple ages and large groups. How high can you go?

Duration: 15+ minutes

Subject: Design Thinking, Engineering

You’re the mayor of a growing town and you need to decide whether or not to build a new dam to generate electricity. What factors will you consider? Would thinking like a computer help you decide? Play Responsible Reservoirs to find out!

Things are heating up and we’ve created five summer-themed design challenges for you to try.

​

​

Who needs boring old plastic? Get creative and use simple at-home chemistry to transform natural materials from living seaweed into flexible, colorful string! What will you create?

Duration: Make algae gel: 20 min
Let gel rest: 1 hr- overnight
Make calcium bath: 5 min
Make string: 30 min

Subject: Biodesign, Chemistry, Materials Science

Download one of our techtastic coloring pages, and then color at home or with your friends over video chat.

We know that our hands carry a lot of germs, but seeing is believing! This fun, two-person activity has a friend use colored cornstarch to create a trail of evidence of things they’ve touched. Then, using computational thinking instead of looking, you’ll create a sequence of questions to help you figure out what surfaces are “contaminated.”

Duration: 20+ minutes

Subject: Computational thinking, algorithms, problem-solving

In this activity, you will play the role of a product designer, identify a user (like a favorite stuffed animal or person!) and get to know their individual needs. You will create a design concept for a face mask, focusing on its fit and comfort.

Duration: 30 minutes

Subject: Design Thinking

Design a device that can pick up three different objects from at least three feet away. It’s a challenge for the social-distancing ages!

Duration: 45+ minutes

Subject: Design Thinking, Mechanics, Simple Machines

A linkage is created by connecting two or more rigid parts to make a flexible hinge; you can keep it simple or develop complex mechanical motion by connecting multiple linkages to create all kinds of contraptions. (Think flapping wings, dancing robots, chomping sharks!) At The Tech we especially love how linkages inspire the creation of whimsical characters with surprising motions.

Duration: 20+ minutes

Subject: Design Thinking, Engineering

Some people may call it a junk drawer, but we like to think of it as a treasure chest. Our guide and video will show you how to repurpose your trash into treasured materials that you can use to design, build and create!

Try one of our jigsaw puzzles with some of our favorite sights around The Tech Interactive.

​

​

In this design challenge, you will create your own roller coaster, using a marble or small ball as your cart. This activity is a great introduction to hands-on engineering for children 6 and up, and it can be used to introduce connections of energy and friction for older children.

Duration: 20+ minutes

Subject: Engineering, Physics

In this classic design challenge, you will be creating a vehicle to transport a passenger, such as a small toy, from one end of a zipline to the other.

Duration: 30+ minutes

Subject: Design Thinking, Engineering

Create a storm drain cover that can keep trash out while letting water pass through in order to protect our waterways.

Duration: 45 minutes to one hour

Subject: Engineering, Earth science

Engineer a solar oven using some basic kitchen supplies, construction paper and a box. Then test it by making s’mores!

Duration: 40 minutes to build; one hour to “cook”

Subject: Solar radiation and energy, greenhouse effect
