What makes something food?

5/4/2017

 
What makes something a food?  Through a fairly in-depth lab, sixth graders uncovered that all foods contain either sugar, starch, fat or protein.  Plants even contain these nutrients making them a food source.

Water, however, is not a food source.  While we need it, students uncovered that it contains no nutrient that defines it as food.  It doesn't give the body energy or building materials!  We'll be connecting this to the trout mystery!

Looking at What's in Food!

4/23/2017

 
Since many students wondered what was happening to the trout's food sources, we agreed to examine food in the first place.  Looking at various food labels, students agreed on the following:  that all foods contain some kind of protein, fat, or carbohydrate to give us energy and help us grow and repair our bodies.  Since trout are living organisms, too, they must also need various combinations of these substances.  We also figured out that there must be a way to test what substances are in our foods, so next week we'll be doing a bunch of chemical tests to figure out just that!

Generating Questions Related to the Changing Trout Population

4/23/2017

 
Picture
As sixth graders dig deeper into understanding the phenomena of a changing population of organisms, our problem hit close to home as the organism we'll be studying is local to Lake Michigan, which is literally blocks away from our school.  Students quickly saw that Lake Michigan is connected to a vast number of other waterways, and its changing population over decades can possibly be caused by many factors. We'll be asking lots of questions as they relate to food availability, reproduction rates, environmental changes, and other organisms that are connected to the trout.

Asking questions like biologists do!

4/17/2017

 
Picture
After we did some outside field-studies, we're asking questions like biologists do!  

Considering all the factors that can cause a population to change, students generated questions that focused on four sub-areas:  other organisms, reproduction, food and environment.  We'll begin applying these same question-asking strategies to a population of local animals, trying to figure out why their population fluctuated over time.  

Kicking off our Unit!

4/5/2017

 
To kick  off our biology unit focusing on the fluctuations in a population of organisms, we hit the field by looking for interactions between living things in their environment right in our school's garden.  We took some time to look for living things, and acknowledged that the work of biologists is often slow and time-consuming, as we look at the subtle things that mother nature has to offer.  We'll be using the ideas behind what interactions reveal to us to help us uncover what organisms need for survival.  Check back as we begin our driving question board next!

    I love that this unit hits so close to home with the Great Lakes!
