Rainforest Bird Beak Buffet

Author(s): Claudia Scharff

Rainforest Bird Beak Buffet

Students will look at pictures of 5 different rainforest birds and share their similarities and differences.  Each student will be given one of 5 tools and one of 3 cups to represent respectively a beak and stomach.  Students will go around the room and forage for "food," respresented by fake and real food.  They will discover that their "beak" and "stomach" allow them to eat only certain kinds of of food and consider the implications of this.

The Lungs and Respiratory System

Author(s): Kimberly Besst, Deborah Rauchwerger, Karen Hauser, Robbie Ruelas,

The Lungs and Respiratory System

Students review what they already know about breathing and the respiratory system. After a brief introduction to the respiratory system, students break into two groups and rotate through two stations. At one station the students observe and touch human lung specimens and discuss the effects of smoking. At the other station, students simulate the effect of astma on breathing.

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.

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.

Hands On With Cells - Using Slide Viewers and Microscopes

Author(s): Chris Cain and Soroya Wood

Hands On With Cells - Using Slide Viewers and Microscopes

In this activity students use microscopes and slide viewers to visualize cells and record what they see. Emphasis is on *recording observations*. Students are introduced to new technologies and to the diversity of cells that make up our body and that exist in plants.

Meet a Land Snail

Author(s): Jennifer Howard and Reba Howard

Meet a Land Snail

In this lesson students will play a guessing game, observe land snails, and create a realistic drawing of a land snail.  At the end of the lesson they will brainstorm things they wonder about Land Snails.

This lesson is alternate or introductory lesson to the FOSS lesson on observing land snails.  Students begin and end the lesson as a whole group and observe either independently or in pairs.

Perception and the Brain

Author(s): Erin Currie, Eirene Markenscoff-Papadimitriou, SEP Staff

Perception and the Brain

In this lesson, students are introduced to how the brain interprets and uses sensory information from the visual system to guide how the body moves and performs various tasks. This lesson makes use of a specialized set of goggles with prism lenses that shift what the wearer sees. Using these prism goggles, students will see first hand how the brain adapts over time to changes in what we perceive. The lesson also makes a connection to the brain and brain function by giving students a chance to see and touch a preserved brain specimen.

What factors affect the oxidation of apples?

Author(s): John Rivera, Lillian Seu, Juliet Rose Girard, Anthony Shiver

What factors affect the oxidation of apples?

Students observe the browning of apples after cut and being exposed to air and brainstorm ideas about why this might be happening.
Students think about ways to slow down or prevent the browning effect and in teams create and conduct a simple experiment to test their ideas.

How does the pH environment affect bioavailability of Iron?

Author(s): John C. Rivera, Lillian Seu, Juliet Rose Girard, Anthony Shiver

How does the pH environment affect bioavailability of Iron?

Dietary minerals are available through ingestion of food and supplements.  In this lesson, students first examine the chemical reaction of two forms of iron, Fe0 and F+2 with various pH conditions of either the stomach or intestine to determine how it gets absorbed and eliminated in the body. Then students isolate iron from the foods we eat (such as cereal) using a magnet to attract elemental iron or Fe0.

Forensics Crime Lab

Author(s): Molly Darragh, Maria Jenerik, Sarah Maifeld, Christopher McClendon

Forensics Crime Lab

A crime is staged in the classroom.  After observing the crime scene, student identify and collect crime scene evidence.  Students use blood typing analysis, microscopy, and chromatography to analyze the evidence.  The list of suspects is narrowed to identify the potential culprit. This lesson may be done in two parts or as one long session.

Observing and Drawing the Structures of Guppies and Goldfish

Author(s): Jennifer Howard and Reba Howard

Observing and Drawing the Structures of Guppies and Goldfish

This lesson is a modifcation to FOSS Investigation #1 in the Animals 2 x2 unit.  In this version the students are observing both guppies and goldfish at the same time as their first introduction to the fish (where as in FOSS they have them look at them separately on separate days). Also, in this version, students not only observe, but learn to do drawings "like scientists".  They use new worksheets and write a few words about what they see.

Pollination

Author(s): Anastasia Pickens and Arthur Millius

Pollination

This activity approaches pollination through: 1) a game to understand the role of the pollinator, 2) a flower dissection to understand the structure and function of flower parts, and 3) a video to see seed dispersal in action. Allow 2 sessions to complete

Introducing the Process of Investigative Science Using Worms

Author(s): Linda Akiyama

Introducing the Process of Investigative Science Using Worms

Students are introduced to the process of investigative science through a guided inquiry activity. Given a testable question and materials, students as a class make predictions, and design an investigation with guidance from the teacher. Then in pairs, students do the investigation, collect data, draw conclusions, and discuss ways to improve on the investigative design.  After this activity, students will be able to develop independent investigations in this and other subject areas.

 

Students learn that a living thing can sense and respond to its environment.
