Earth and Beyond

Lesson Sheets Layout

This is a Ready-Ed Publications' book preview. Using the activities in this book, students will gather information about the earth and the effects of natural phenomena on the earth as a whole. Students will have opportunities to research natural events such as catastrophes, investigate how humans can cope with space travel, and study the features of the universe and gain an understanding of the seasons. They will also be involved in sampling soils, gathering data from various sources, drawing diagrams and conducting research into soil erosion.

STUDENT LESSON SHEET Lesson title Student learning activities

Each lesson has the potential to: • extend into more than one lesson by having separate parts to the lesson sheet. Some sections of a lesson may need planning on other paper before final copies are transferred to the lesson sheet. Some lessons may be too long for one lesson and could be completed at another time. • expand into other curriculum areas using a similar theme. There are ideas for crosscurricular integration with other learning areas. Sometimes a whole day’s work could be planned around one lesson sheet.

Science Materials and Equipment The equipment needed has been kept to a minimum to facilitate ease of planning. It is readily available in schools or is easily acquired. All lesson sheets are outcome linked to the various curriculum documents (see page 6). Answers are provided where necessary (see page 24). Other books in the Practical Science series:

Soils

This is a Ready-Ed Publications' book preview. Materials: Learning Outcome:

• Illustrates ways that use of the Earth’s resources changes the physical environment.

Each pair/group will need:

• • • • • • •

dessert spoons jars labelled 1 to 4 access to soil (within the school grounds) magnifying glasses scales to measure grams gloves for the children (optional) clipboard and paper for notes

Lesson Ideas: This activity can be done in pairs/groups. • Be sure to explain what this activity is about at the beginning of this lesson. Students will need to know the sorts of notes they should make as they collect their soil samples. • Children will need to visit the school grounds to collect their four soil samples. They should collect as wide a variety of soils as possible, e.g. sand from the sand pit, red dirt, garden soil, compost and so on. • Each pair/group needs to collect approximately two spoonfuls of each soil type and to label their samples carefully. Students should take notes (on clipboards) about where the particular sample was collected and what it is being used for (e.g. garden, path, etc.). • Children then return to the classroom to study the four soil samples. They should identify the type of soil (sand, clay, compost, etc.). Students will also need to weigh their samples. • Using magnifying glasses, students can have a closer look at their samples, observing any foreign bodies found in their collections. • In groups, students discuss any problems they had collecting and analysing the soil data. Children can write their own responses for the Reflection (section E) on the back of their worksheet. • If possible, take photos of the children at work and have the children write up captions for a class display. • Lesson 2: Soil Erosion is an ideal follow up to this activity and examines soil erosion in the school grounds.

Integration Ideas:

Go to www.readyed.net

English (Speaking and Listening): Children can present a talk on their data collection to a class/ group using the lesson sheet as a guide. Research: Children can conduct research on the different uses of soils in the school grounds and what is required for each use, e.g. sand in the playground, gravel on the driveway and so on. 8

Lesson Ideas: • Discuss the activity requirements and organise the research materials for the students. • Conduct a class brainstorm on the terms in section A before allowing the children to work on their own answers. • Children research answers to these terms using the available books and websites. • For section B, children should be able to describe a “light-year” and also be able to understand the distance involved. • There are many websites suitable for research: www.kidsastronomy.com/ www.worldalmanacforkids.com/explore/space.html coolcosmos.ipac.caltech.edu//cosmic_kids/AskKids/def_lightyear.shtml www.enchantedlearning.com/subjects/astronomy/stars/startypes.shtml members.aol.com/_ht_a/bobalien99/stardiff.htm www.nasa.gov/vision/universe/features/ www.scitech.org.au/planetarium/links.html – Scitech links • Children should draw a diagram of the star, label it and write a description. If possible, children could use the lesson sheet to plan a mini-project about stars.

Integration Ideas: English (Spelling): Create a list of “universe” words for a spelling/word study activity. The Arts: Children create, in groups, a model of each type of star using papiermâché. Excursion: Visit a planetarium. Maths: Use the speed of light (300 000 km/sec) to complete calculations for the distance of a light-year (e.g. 300 000 x 60 x 60 x 24 x 365).

Lesson 8

Teachers' Notes

Earth and Beyond

Catastrophes

This is a Ready-Ed Publications' book preview. Learning Outcomes:

• Identifies changes in the atmosphere and the interior of the earth that cause catastrophic events.

Materials: • research materials for children on the theme of catastrophes (library books, posters, websites, newspapers, magazines, etc.) • computer access to prepare presentations using programs such as MS Word or PowerPoint • large piece of art paper for each child • project stationery (card, pad paper)

Lesson Ideas: • Discuss the definition of “catastrophe” and provide some recent examples of natural catastrophic events, e.g. Asian Tsunami, Hurricane Katrina, Cyclone Larry. Children choose a particular event for individual research and begin the plan of their project. • Using the sections from the worksheet, students plan where the items will be placed on the final project sheet. • When finished, the plan should be checked and the children can begin to collect the information for each section. Starting points for research: • There are many websites for research, for example: www.nationalgeographic.com/forcesofnature/interactive/index.html earthquake.usgs.gov/4kids/ – Earthquakes www.pbs.org/wgbh/nova/avalanche/ – Avalanches www.pbs.org/wnet/nature/hawaii/ – Hawaiian Disasters

Integration Ideas: English (Speaking and Listening): Children can present their projects as a talk. English (Spelling): Collect a list of the glossary words to use in a spelling or word study activity. English (Writing): Creative writing using the catastrophe theme. Story titles can include The Day After, Disaster! and so on. Society and Environment (SOSE / HSIE): Children collate data on a world map showing where all the catastrophes occur. Ideally, create a class wall map that students can draw on.
