TEACHING SCIENCE
For K-12 Science/Biology Education, I recommend the websites in the following below:
- View all animals and plants A-Z by their classifications and see different Habitats and Ecosystems.
Go to https://animals.sandiegozoo.org
-DNA from the beginning_Animated experiments in modern genetics:
http://www.dnaftb.org/#molecules
-DNA Learning Center_Interactive Biology Animations:https://dnalc.cshl.edu/resources/animations/
- Interactive Prentice Hall Biology:
http://www.phschool.com/webcodes10/index.cfmwcprefix=cbk&wcsuffix=9999&area=view
- 3-D Human Anatomy: https://human.biodigital.com/
-Visual learning materials and virtual tours: https://www.thinglink.com/
- Interactive Simulations for Science:
Science refers to a system of acquiring knowledge. This system uses observation and experimentation to describe and explain natural phenomena. The term of Science also refers to the organized body of knowledge people have gained using that system. Scientific thinking usually begins with observation, which is the process of gathering information about events and processes in a careful, orderly way. The information gathered from observationsis called data. After making first observations, a researcher will propose one or more hypotheses. Scientists generate hypotheses using prior knowledge, logical inference and informed,creative imagination. Some hypotheses are tested by performing controlled experiments. Other hypotheses are tested by gathering more data. The conclusions scientists draw from experiments or data must be valid. To be valid, a conclusion must be based on logical interpretation of reliable data.

LAB SKILLS
In photosynthesis lab, we will be using the aquatic plant Elodea to determine primary productivity of small model of ecosystem(a test tube). We expect to see an increase in dissolved oxygen concentration under bright light conditions because Elodea is a photosynthetic plant. We will also use a probe and data collection system. We will record the data for both bright light and bright dark conditions. Finally, we will create a line graph showing the relationship of time and DO concentration in light versus dark conditions and we will calculate the change in mass of Elodea under light and in dark conditions.

SETTING UP DISSOLVED OXYGEN PROBE
1.Power on the Data collection screen.2. Select "SparkVue" by tapping on the icon.3.Tap the build icon. 4. Select the single-paned template at the top of the template list on the right side of tge screen by tapping on it. 5. Tap the table icon in the top right corner of the new screen. 6. Tap the time column of your new screen and change the units of minutes,then click ok. 7. Your data collection system is now set up and ready to begin collecting and recording the DO concentrations every minute for as long as you keep the system running.

ECOLOGY PROJECT IDEA
Subject-Level : Grade 10Teacher: Ipek Olsun
Topic: Ecosystem EcologyAcqusition: Energy Flow and Recycling of MatterProject Name: Creating a Self-Sufficient Terrarium
In this project:
• You will learn solar energy coming into the terrarium is a basic need of plants inside. The energy flows from the sun to the producers and from the terrarium to the outside by heat in a single direction.
• You will also learn that chemicals essential for life cycle through the ecosystems. You will obtain the substances that plants need to live. Somehow, all chemicals will circulate in the ecosystem and be used repeatedly. For example, when you water plants in the beginning for once, they will use the water again and again. The water cycle basically occurs by the evaporation, condensation and precipitation.
To make a terrarium you need:
Jar,pebbles, sand, charcoal(aktif karbon yada mangal kömürü), soil, rocks, succulents. It may contain cactus, moss, lichen and ferns.
