Milk does a body good ... unless, of course, someone is lactose intolerant. Pupils play the role of pharmaceutical scientists in a guided inquiry lab about lactase. Lab groups collaborate to learn more about lactose intolerance, how...

All mammals have warm blood, are vertebrates, breathe with their lungs, have hair or fur on their bodies, and produce milk for their young. But not all mammals give birth to their young in the same manner. Watch a video that explains how...

Learn more about mammals with this fantastic video! It discusses mammals varying from whales to mice to elephants. Can your class tell the difference between a whale and a shark?

Curdle milk on purpose. Pupils mix vinegar with milk to produce curds and then explore the properties of the curds. Scholars redo the experiment by changing up one of the variables and observing what happens.

Keep the tension up in the classroom. The class first observes as the teacher creates a dome of water above a glass by adding paperclips into an already full glass. Classmates then work in pairs to see how many drops of water can fit...

Milk: It does a body good ... or does it? Using the provided website, scholars sort through information to answer the question. They review a chart demonstrating lactose intolerance by ethnicity and region, and they also compare the...

Around the world, about 2/3 of adult humans are lactose intolerant. Scholars work in small groups to discuss a few statements about lactose intolerance. Then, they watch a video on the topic and readdress each statement. Whole-class...

You've probably spent plenty of time discussing animal adaptations with your young biologists, but what about human adaptations? Explore the evolving traits of humankind through an interactive that combines text and video clips. Scholars...

What's the link between lactase persistence and dairy farming? Biology scholars analyze data to find evidence of the connection, then relate this to human adaptation. Working individually and in small groups, learners view short video...

We all drink milk as babies, so why can't we all drink it as adults? Examine the trend in lactase production on the world-wide scale as science scholars analyze and interpret data. Groups create pie charts from the data, place them on a...

Only one-third of human adults can digest milk. If you're one of the lucky few, you have gene-culture co-evolution to thank. Scholars watch a video to learn how the enzyme lactase is necessary to break down lactose in milk. The gene...

Polymers are an important part of our day-to-day lives, but how much do your pupils know about them? Learn the basics and beyond in a series of activities designed to build skills in observation, planning, organic chemistry, and bonding.

Why is lactase important? Biology scholars explore enzyme function in a structured inquiry lab. The activity tasks lab groups with observing how temperature and pH affect enzyme activity, as well as determining which milk products...

Moooove over, there's a better deal over there! The fourth segment in a series of eight requires individuals to determine the best unit cost for milk. Scholars calculate the least amount they can spend on a particular quantity of milk....

The first substance most all mammals taste is milk. Why are we all so obsessed with milk? Explore the world of lactation, the dairy industry, and different types of milk with a video that explains the science of milk.

The process of making yogurt, starting with fresh cow milk, is the subject of a video that focuses on the importance of bacteria and the many different types of bacteria that can be used in yogurt making. 

In this producers and consumers instructional activity series, students make two small books; one about how milk is produced and processed starting from cows, and the other is about how trees become lumber and other products. They cut...

This visually vibrant activity demonstrates what happens when dish soap weakens the bonds that hold fats and proteins suspended in milk. Perhaps you can have chemistry lab groups perform this activity when they are learning about...

Students observe a teacher demonstration o classifying matter by its physical properties of shape and size. After discussing the definition of matter, students describe the state of matter. They sing a song to the tune of "Bingo." In...

In this five food groups worksheet, students look over a chart containing the five food groups and the seven days of week and color the group they eat each day.

Genetic engineering as a solution to disease tendencies and growth is presented. Examples are given of its use to research micro-organisms that help or hinder farming.  There are many slides with details of the process in a lab, as well...

Students paint on bread using milk and food coloring. In this art lesson, students use their imagination and "paint" something on the bread.
