Anabela Bernardes da Silva (Faculty of Science, Lisbon)

Luz Figueiredo (Primary Education Teacher) www.cienciaviva.pt | info@cienciaviva.pt

Seed germination and plant development

Aims

. Learning practical ways of approaching problems; Control and Assay (scientific method)

. Developing Mathematical skills (the importance of quantitative information in biology research)

. Developing language skills (mother tongue and foreign language)

Age group

Kindergarten and elementary school children

Materials

Experimental protocols: the influence of environmental factors and soil in seed germination and plant development.

Previously tested worksheet www.cienciaviva.pt | info@cienciaviva.pt

Seed germination and plant development

Worksheet A

The influence of Environmental Factors In Seed Germination

Environmental factors: observation of rapid transformations occurring in seed germination

Worksheet B

The influence Of Soil and Environmental Factors in Plant Development

. Influence of soil and each environmental factor:

- growth parameters ( e. g

. measuring height of plants, length of roots, nº leaves, etc)

- weighting ( e. g . weight of plants, leaves, root, etc).

Worksheet C

Biomass partitioning

Worksheet D

Extraction and separation of plant pigments by chromatography www.cienciaviva.pt | info@cienciaviva.pt

Author

Raquel Gaspar, Post-doc student www.cienciaviva.pt | info@cienciaviva.pt

The Little Girl from the Sea

Aim

Creating curiosity and interest in discovering nature, learning about marine animals.

Age group

Young children (primary education + kindergarten)

Worksheet

Guidelines (multidisciplinary approach):

. Story telling/listening (The Little Girl from the Sea)

. Biology concepts: marine habitats and animals

(morphology)

. Guides for workshops: animal model building

. Field trips to marine environments

. Creative arts activities: musical activities/performative activities www.cienciaviva.pt | info@cienciaviva.pt

Bioethics in schools

Author

Pedro Fevereiro, Institute of Biotechnology, member of the Council of Ethics

Consultant

Mafalda Lapa, biology teacher www.cienciaviva.pt | info@cienciaviva.pt

Bioethics in schools

Activities

Guidelines for discussions of Bioethics issues in schools:

. Video of a recent debate (scientists of Council of Ethics’ members + secondary education students)

. Film GATTACA previously used as a starting point for a debate between Portuguese and Brazilian schools

. Case study (based on real and made-up situations)

. Forum (internet) used by Portuguese schools for 3 years; still online.

. “ Ethical Forum for Young People ”, Danish organization www.cienciaviva.pt | info@cienciaviva.pt

DNA damage and repair: daily threats to our genome

Authors

Carmo Fonseca, João Ferreira, Teresa Carvalho, Margarida Gama-Carvalho

Institute of Molecular Medicine, Faculty of Medicine, Lisbon www.cienciaviva.pt | info@cienciaviva.pt

DNA damage and repair: daily threats to our genome

Changes in the DNA molecule as a result of environmental agents

(solar radiation, tabacco)

How these alterations can be repaired or may lead to the development of diseases

(cancer)

- Two worksheets:

1. Mutagenic effects of environmental agents: a laboratory test

2. Effects of sun exposure on your body – measuring UV irradiation

Age group

Middle and Secondary education schools www.cienciaviva.pt | info@cienciaviva.pt

DNA damage and repair: daily threats to our genome

5. 1 Mutagenic effects of environmental agents: a laboratory test

Aims

Explore the effects of tobacco and UV radiation on DNA in a hands-on lab experiment.

Experiment

- model organism: Serracia marcescens (based on the Ames test)

- Support of IMM to Portuguese schools

- bacteria exposed to tobacco, sunlight or UV source

- mutations: change in the colour of the colonies

- Further investigations: exposing bacteria to other mutagens

Content of the material (laboratory and discussion guides)

- Informative text (DNA, mutations, mutagens; cancer; oncogenic virus; Ames Test)

The experimental activity: protocol and teacher’s guide

- Suggestions for discussion

Basead on:

Rebecca B.R. Milholland and Stefani D. Hines (2004). Tobacco Induced Mutations: A Fun, Visually Impressive

Experiment . The American Biology Teacher, Vol. 66/5, 370-376 www.cienciaviva.pt | info@cienciaviva.pt

DNA damage and repair: daily threats to our genome

5. 2 Effects of sun exposure on your body – measuring UV irradiation

Aims

Explore the deleterious effects of sun exposure and how to prevent them.

Materials

Kits with UV sensitive colour beads for the students to build bracelets

A laboratory guide

A discussion guide

Overview of the project

- Bracelets with UV sensitive colored beads to monitor exposure to

UV radiation

- Variables: sunscreen lotions, clothing color, skin types,

Practical issues

Pack of 2500 beads
