The device is as such, easy to use and care for, rugged and good-looking. More important to you and of course to us is that it is safe to use. During manufacture, we made sure that this product is as safe it can be for children to use. Some residual risk is, however, unavoida- ble. This product, after all, is not a toy in the usual sense but rather an optical instrument that children can use to experiment, research and discover their world. That‘s why we request your cooperation here. The- se operating instructions were written for children but please read them through together with your child or children and answer his/her/their ques- tions. Don‘t forget to explain possible risks. These are summarised under the heading „war- nings“. Please adjust/set up the device together with your child or children and never allow any child to use any of our optical products unsupervised. We hope all users and their parents will enjoy our products. Your Bresser team13

Seek medical treatment for ailments arising from contact with the chemical substances and take the chemicals with you to the doctor.15

Your experiment set is made up of the follo- wing components: 1 Shrimp eggs 2 Sea salt 3 Yeast 4 Gum media 5 Prepared slide “Fabric” (material) 6 Prepared slide “Shrimp” 7 Prepared slide “Honeybee”

13 Prepared slide “Buttery Wings” 14 Cover slips 15 Adhesive labels 16 Shrimp hatchery 17 Slide 18 Pipette 19 Tweezers 20 Dissecting needle 21 Scalpel 22 Magnifying glass What you need to know Caution! When using your experiment set, wear an apron (or old clothing) and rubber gloves! Always carry out your experiments under the gui- dance and with the help of an adult! Your experiment set includes numerous accesso- ries that help you carry out different experiments. You can use all the parts independently of the mi- croscope that you use for your research. You’ll nd a few experiments that you can try out attached to these instructions. You can do them with the individual parts of your experiment set. Shrimp eggs These are special eggs that are capable of survival even when they are dried out. As a result, they are particularly ideal for raising brine shrimp. You can nd out how in the appendix to these instructions.16 Sea salt You can observe the sea salt using your microsco- pe. Salt is a crystal that looks very interesting through a microscope. Apart from that, you will also need the sea salt to make a salt solution, in which you will hatch your brine shrimp. Yeast The yeast in your experiment set is included as feed for the brine shrimp. If you feed them regularly, you will be able to watch how they grow. Gum media This material is a glue that you can use to make per- manent prepared specimens. Prepared slides „Honeybee,” “Fabric“ (material), “Shrimp” and “Buttery Wings” Different prepared slides that you can investigate using your microscope. Empty vials You can keep a few samples in the empty vials (e.g. leaves, and, etc.) Cover slips You use the cover slips to cover specimens that you have placed on a slide in order to observe with a microscope. Adhesive labels You can use these labels to identify your permanent prepared specimens. You can also use them to la- bel the empty vials. Shrimp hatchery You can hatch shrimp in the different chambers and observe the different stages of development. Slides You place the specimen on a slide. After you have covered it with some water or gum media, you can place a cover slip on top. Then you place the slide under the clips on the microscope.17

Scalpel The scalpel is a sharp knife that you can use to slice specimens/samples. Tweezers These are a type of pincers that you can use to pick up smaller objects. Dissecting needle A dissecting needle can be used for many things. You can use it to scratch the surface of a specimen, to x objects in place or to stir liquids. Pipette You can use this instrument to soak up liquids in small amounts and squirt them out again. To soak up liquids, push the upper part (head) of the pipette together and put the opening on the lower part in the liquid. Let the head go and the pipette will ll with the liquid. When you want to release some of the liquid, simply push the head together again. The more carefully you press, the less liquid will come out of the opening. Magnifying glass With the magnifying glass, you can observe objects with 2 times the magnication. After use To make your experiment set - and the enjoyment of it - last longer, you should make note of the follo- wing for after each use.

1. Clean the cover slips, slides and the microscope

instruments carefully with water and some soap. Caution! Cover slips, slides and the instruments have sharp edges and are in some cases pointed. Make sure to always let adults help you when cleaning, so that you don’t hurt yourself! Warning! The cover slips are particularly thin and could break. It is best to place them on a piece of paper on a hard surface for cleaning.

2. Close all the vials tightly after use. Some contai-
