Introduce basic Earth and space science to your budding astronauts. This handout works in two ways, the first part provides information about the sun, moon, eclipses, and Earth to be read to or by the class. The second part is composed...

Understanding fractions and how big or small each fraction represents is key to solving these story problems. Determine how much pizza was eaten by two different people by asking your mathematician to use their fraction knowledge!

Does it ever seem like time is slipping through your fingers? Model the passing of time with an hourglass activity in which individuals determine whether hourglasses are the most efficient way to measure time.

Did you know that jumping spiders sometimes wear water droplets as hats? A seventh grade science lesson introduces the concept of what makes up water: tiny molecules that are attracted to each other. Starting with a...

How do you know there is air? Can you see it, smell it, feel it? To begin the investigation, learners watch a video and discuss what they know about air and the atmosphere. Then, they participate in five different hands-on, inquiry-based...

Decisions, decisions! Small groups decide on their dream career then enter a scenario that challenges them to make another big decision—if stranded on a deserted island, who would be saved or fed to the sharks. Because decisions are...

Scientists could measure the diameter of the sun before they knew its distance. Scholars construct a simple mirror box to measure the diameter for themselves. They compare this measurement with the official size, listed in a...

What does size have to do with it? Learners analyze different mixtures, both homogeneous and heterogeneous, to discover the properties related to the size of their particles. The activity connects these properties to those of...

When van Leeuwenhoek saw cells and single-celled organisms for the first time, he knew these small things were a big deal! Share his discoveries with young learners through a narrated video, model-building activity, and scale study....
