The power of observation

Students each receive similar looking objects (marble, gem stone, bead, rock) and are given some time to make and record as many observations as possible. Then students at each table group mix up their objects and take turns reading out their descriptions while the rest of the group is trying to identify the described object.

Oobleck

Author(s): SEP Coordinators

Oobleck

Students will read the first part of the book by Dr. Seuss, "Bartholomew and the Oobleck," where they learn about the mysterious substance "Oobleck",  created by a group of magicians in the story. Students then make Oobleck from cornstarch and water and observe its properties, realizing that Oobleck does not behave like other solids or liquids.  After experiencing Oobleck first hand, students create their own ending to "Bartholomew and the Oobleck".

Mini Medical School - Hematology

Author(s): Rustom Falahati, Megan Robblee, Bonnie Daley

Mini Medical School - Hematology

This is a two-class lesson plan. During the first class students are entered into a "mini-medical school" where they will learn about the functions and components of blood and make a candy model to reflect their relative proportions.  At the end of the class, they graduate medical school as hematologists. The next day they will be presented with a mock patient with a blood disorder. In groups, they will attempt to diagnose the patient using blood smears, results of lab tests, and patient histories.

Amylase - Exploring digestion and evolution through a molecular machine

Author(s): Becky Fulop, Juliet Girard, Thomas Noriega

Amylase - Exploring digestion and evolution through a molecular machine

The lesson is designed around two sets of experiments. The first set demonstrates that amylase is a digestive enzyme that degrades starch into sugar, can do so repeatedly and, like many enzymes, is sensitive to acid. The second set of experiments demonstrates the variability of amylase activity in different students' saliva.

Antigen switching in malaria

Author(s): Mary Kate Alexander

Antigen switching in malaria

In this activity, students will model how the parasitic malaria protist Plasmodium falciparum evades the host immune response through a phenomenon called antigen switching.  Specifically, slips of paper representing malaria-infected red blood cells will be used to demonstrate how random changes in the expression of Plasmodium proteins that display on the surface of human red blood cells helps the parasite avoid destruction by the host immune system.  Students start with a single infected red blood cell with a specific surface marker protein, and from there will simulate the spread of infection through multiple generations of infection (each generation consisting of a parasite infecting a red blood cell, dividing and multiplying inside the red blood cell, then bursting to release new parasites that go on to infect new red blood cells).  Student will find that the parasite occasionally changes the type of surface marker protein expressed over several generations.  When the immune system begins destroying infected cells displaying the original surface protein, cells that have switched to expressing a different protein survive and continue to divide.

Demonstrating how to Conduct Controlled Investigations: Example Using Sound

Author(s): Linda Akiyama and Ranyee Chiang

Demonstrating how to Conduct Controlled Investigations: Example Using Sound

The teacher conducts an investigation to compare the sound produced by two different sized pipes (higher pitch, lower pitch, louder, softer).  The teacher conducts the experiment multiple times, each time changing different variables.  The students are "directors" and are asked to "cut" the scene when they observe something wrong with the experiment.

Introducing Models to Elementary School Students

Author(s): Linda Akiyama and Ranyee Chiang

Introducing Models to Elementary School Students

Students learn what a model is by comparing a model of the tongue to their own tongue. They practice asking themselves, "How is this model like the thing it represents, and how is it different?"  This format of questioning can be used when using any model in science and can be used to check students' understanding and misconceptions.

Cleaning Water: A 5th Grade Standards-Based Science Unit

Author(s): (Coach) David Mann, (Team Members) Kevin Baldizon, Jeff Foote, Robin Schneider, Ben Wieman

Cleaning Water: A 5th Grade Standards-Based Science Unit

Many children around the world die due to drinking contaminated water.  This engaging science lesson will allow students learn how to build and use a simple homemade filter system to clean contaminated water. This 5th grade, standards-based lesson is great for California Science Content Standards Earth Sciences.  Students make observations, collect data and form hypothesis.  The end result is a gratifying surprise that they will enjoy while learning basic investigation and experimentation concepts.

Sheep Heart Dissection

Author(s): Chris Cain and Soroya Wood

Sheep Heart Dissection

Students observe and dissect a sheep heart. In doing so, they learn about how the heart works and what it really looks like.

While this lesson is adaptable for many grade levels, it is a great fit with California's FOSS 5th grade Living Systems kit and that kit's goal of learning the structures and functions of the circulatory system.
