Choose a recipe to double (or triple, quadruple, or halve). Show everyone the recipe and engage them in figuring out: How much will we need to increase the recipe to feed everyone?

Cake by Conduction
Source Institutions
In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.

How to Extract DNA From Anything Living
Source Institutions
In this genetics activity, learners discover how to extract DNA from green split peas.

Cabbage Chemistry
Source Institutions
In this chemistry activity (page 5 of the PDF), learners make an acid-base indicator using cabbage. Learners then explore how various subtances react with this indicator.

Spaghetti Bridge
Source Institutions
In this engineering activity, learners investigate the differences between the strength of bridges made from flat and round building materials.

Guar Gum Slime
Source Institutions
In this activity, learners create a gelatinous slime using guar gum powder and borax. Educators can use this simple activity to introduce learners to colloids.

Scented Dough
Source Institutions
In this activity, learners follow a recipe to create play dough scented with fruit-flavored drink mix.

Conduction Countdown
Source Institutions
In this quick SciGirls activity (page 1 of the PDF under SciGirls Activity: Doghouse Design), learners will be introduced to the concept of thermal conductivity.

Handy Family Tree
Source Institutions
In this bilingual (English/Spanish) activity, learners create family trees by tracing the hands of their family members.

Milk Plastic
Source Institutions
In this activity, learners transform everyday milk into small plastic figurines and jewelry. Use this activity to introduce learners to monomers and polymers.
Build a Super Structure
Source Institutions
In this activity, learners use things from the kitchen as building materials to explore how shapes contribute to the strength of different structures.

Radioactive Decay of Candium
Source Institutions
In this simulation, learners use M&M™ candy to explore radioactive isotope decay.

Touch Down
Source Institutions
In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

Curious Crystals
Source Institutions
Learners carefully look at four known household crystals.

We all Scream for Ice Cream
Source Institutions
In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.
