This document can help you save some time in planning your lesson and preparing worksheet. Aim: investigate the process of osmosis by measuring the change in volume of the egg and then relate this to how water moves in and out of living cells (egg). You can combine this experiment with planning a lesson about cells (movement of particles) and when students need to learn about osmosis. Also, this experiment is like a research paper. Students need to perform experiment, observe and analyze results. In the end they need to decide what graph they will use to show their result and make conclusion.

This document will help your students to realize why cells are so small and how these is connected with a transport of substances. In the end of the document are answers on the questions. This document is made as a research that can be done at home or in the classroom. My suggestion is, if you are doing these in class do some steps before, so that you do not lose time during the lesson. In this document is included; making prediction, observation, performing experiment, using math (calculation of surface area and volume), art (making sketches), writing results and making conclusion.

In this worksheet students will be able to understand what is diffusion. They will use experimental skills and strategies.

This worksheet will help students to understand the main function of kidneys (filtration and diffusion). Students will use mathematics skill, investigation skill.

This worksheet will help students to understand what is transpiration and in which part of the leaf will happen. Students will use experimental skills and strategies.

This worksheet will help students to understand what is transpiration. They will use experimental skills and strategies.

The rotational model is used in group work. The teacher needs to divide students in five groups. Assign one question to each group, and students write down their thoughts and answers in the form of notes. On the teacher’s sign, students need to switch question with next group. Students read what their predecessors wrote down and write down their ideas. The rotation is done until the groups get the sheet with the question they started with.

I made mind map for nutrients and their functions. Included nutrients are: carbohydrates, proteins, lipids, vitamins, minerals, water and fibre.
