A series of math and science activities feature M&M's® as manipulatives to help kids work through equations. The resource includes exercises on finding averages, percent of compositions, moles in chemical reactions, genotypes and...

Are you looking for lab sheets to go with your class experiment on plant response to light? You are no longer in the dark! This is a lesson that was written for a unit on light, but could easily be used to demonstrate plant behaviors in...

Young astronomers follow a step-by-step procedure for dividing a lump of dough into parts, resulting in a scaled volume set of puny planets. Along with the printable directions is a template chart of planet names on which learners can...

Little learners experiment with sunlight and map out how light travels. Using a mirror and slotted card, they find out about items that can reflect or absorb the light. They experiment with a variety of materials to find out how light...

Our final proposal for the cost of the bridge requested is ... In the last segment in a series of 10, pairs work together to develop a proposal for a city bridge design. The class completes a cost comparison between concrete and steel to...

Not only do future engineers learn the difference between accuracy and precision, they also get some hands-on experience using different measuring tools. 

Class members explore the carbon cycle in the final installment of the 10-part Discover Your Changing World series. They play a simulation game where they walk through the steps carbon takes as it cycles through the different layers...

Complete teacher narrative and presentation slides for teaching about Earth's water make up the bulk of this lesson. Embedded within the slide show, you will find videos about the water cycle, keeping track of the limited supply of fresh...

Cells of different organs have unique cell functions. Learn how cell functions vary depending on their roles in the body using an inquiry-based activity. Scholars analyze the cell structure to make comparisons to its functions, allowing...

Investigate the amazing ability of plants to filter contaminants from water with this series of in-class demonstrations. After placing six small, potted plants in plastic cups, different solutions and mixtures are poured into them that...

Don't let your eyes play tricks on you ... use scale to keep your eyes in check! Young scholars observe images without scale and try to identify the structure. Then, they look at the same image with a scale bar and assess whether their...

What does it take to train your brain? Learners explore the question as they experiment with their own memory and motor skills. They attempt to trace an object using a mirror and then score their results over several trials. They then...

Intended to supplement your existing cell function and organelle lessons, pairs work together to develop a real-world analogy for cell structures. In addition to writing paragraphs about the comparison, each group will make a short...

Can you visualize one billionth of a meter? It's not easy to understand the scale of a nanometer. Learners use a hands-on lesson to develop an understanding of the size of a nanometer in comparison to common objects. They walk away with...

Has your class wondered how fast a human could run or how high they are capable of jumping? Help them understand these concepts as they explore acceleration and use an accelerometer to make semiquantitative measurements of acceleration...

Rainwater doesn't stay where it falls. Learners use modeling to demonstrate how rainwater disperses once it hits the ground. The activity includes an investigation of the height of the water table in an aquifer and how it is affected by...

How much is too much nitrate in the water? Young scientists discuss the question after they run their own nitrate tests. They also consider sources of nitrates and offer explanations for the levels.

Teams learn about the size of a nanometer by measuring objects and converting those measurements. A worksheet then tests the groups' abilities to use nanometers by having them determine the size of objects that are too small to...

Compare what shells look like on the outside with what makes that happen on the inside. Scholars begin by sorting an various seashells by their physical characteristics into phylogenetic trees. They then conduct a DNA comparison of...

How do computers sort data lists? Using eight unknown weights and a balance scale, groups determine the order of the weights from lightest to heaviest. A second worksheet provides the groups with other methods to order the weights. The...

If you're reading the story "Merry Christmas, Geraldine" by Holly Keller, this is a fantastic cross-curricular resource to use. Complete with activities for language arts, science, social studies, art, and math, you'll get the most out...

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....

Class members have an opportunity to experience how to use a public key to encrypt information and a private key to decrypt it. Groups create their own public key and encrypt information then develop private keys to decrypt this...

It might be silly to determine the creep rate of putty but groups will enjoy making different formulations of silly putty and playing with them to understand how the different mixtures behave. The second part of the activity has groups...
