Class 1: Photosynthesis

 

Where do you get your energy from?​

​

Your energy comes from the food you eat. Energy is passed from one organism to another along the food chain.

Every food chain begins with an autotroph organism. They take energy from light, and transfer some of the energy into the food that they make. When we eat food we get some of that energy.

 

In this unit, we will look at how plants use energy from light to make food. 

​

​

​

​

​

​

Let's start by watching this video about the photosynthesis equation:

​

​

​

​

​

​

​

​

Then we will answer some questions that will help us understand more about this process:

​

​

​

​

1) Use ecosia or any other search engine to find the etymology of the words "photosynthesis" and "autotroph"

​

2) Draw and explain the process of photosynthesis:

​

 

​

​

​

​

​

​

​

​

​

​

​

 

 

3) Write the word and chemical equations of this process

​

4) One of the results of the photosynthesis

process is the production of biomass,

what is meant by biomass?

​

5) Besides plants, what other living things perform photosynthesis? Draw them and write their names

​

​

​

​

​

​

6) Explain this meme using the website of National Ocean Service

​

​

​

​

​

​

​

​

 

 

 

 

 

 

 

 

 

​

 

In most plants, the leaves are the organs that carry out photosynthesis.

​

The goal of today's class is to learn more about the structure of leaves that allows them to perform this critical process.

​

Let's start with some questions to check what do you know about the topic:

​

​

​

​

​

​

​

​

​

​

​

​

 

After discussing these introductory questions, we will have a rotation dynamic in which you will move through different activities:

Class 2: Leaves

What is the name of the pigment that gives the leaves its green color?

What is the part of 
the cell where we
can find this green
pigment?

Why are leaves
green but roots
are not?

1. Classifying leaves

Visit the website TREEHUGGER and classify the leaves according to their shape, arrangements, medges and venation

2. Leaf model

1) Color the leaves on the model
2) Cut the parts
3) Assemble it according to the
EXAMPLE

3. Observing Leaves

Draw and color the leaf in the microscope and the leaf with its veins you have on the table
