Each year teachers are faced with the task of integrating emerging science concepts and issues into established science curriculum. This year renewable energy education in the classroom is the integration task that teachers have to mediate. Fortunately there are a lot of projects that can be done using a wind turbine, such as AC/DC current […]
Use TesTab Dissolved Oxygen/BOD Kitinstead of lab protocol. Use a dissoved oxygen tank meter. Once samples are fixed, they can be stored in refrigerator for titration later. Expand study to include natural water bodies (lakes, ponds, etc.). Have students conduct a seasonal study of these water bodies. Remember that science lab kits can be […]
Teachers, see the biology lab tips for transpiration, especially if you are teaching AP classes. Use house plant if bush beans are not available. Cut plant stems and insert stem into tubing while stem is submerged in a pan of water. This prevents air gaps from forming in xylem vessels. Buy disposable glass pipettes (and […]
1st look at the DNA Extraction Science Fair Project kits> Use CO2 from Alka Seltzer to knock out flies initially, then place on “ice stage.” Have student lab T.A. maintain fly cultures. Remember to go over ether safety tips when working on fly biology science fair projects.
4 Molecular Biology Lab Tips: Practice your demonstration techniques before helping your students develop their own biology science fair projects. Borrow electrophoresis equipment. Do demo of electrophoresis. Do simulation of electrophoresis. Use predigested DNA for electrophoresis.
Obtain catalase from Sigma. May be stored for years in freezer. Use bakers yeast culture as catalase source. Use liver as catalase source. KMnO4 stains may be cleaned up using H2O2. Use syringes to save time (and money) in volume measurements. Do a thorough cleaning of your lab freezers or refrigerators. Dispose of items that […]
Get the whole classroom involved in alternative energy with the 10 savonius wind turbine lesson plans, demonstration ideas and student hands-on activities. Definition of savonius: A windmill composed of two semi-cylindrical offset cups rotating about a vertical axis. This is a mechanical engineering term. Wind energy is a renewable energy resource that has the potential […]
Teachers, here are some lab tips for osmosis and diffusion: Your students will have a lot of fun learning about diffusion while engaging Diffusion Races! Use liquid laundry starch or soluble packing pellets in place of soluble starch. Have students tie knots in the dialysis bags instead of using string. Have each group do each […]
PicoTurbine wind turbine energy science fair projects are a great option for energy lesson plans. These projects are easy to break down into steps and they are easy to teach. Also, your students are going to love building their own wind turbines and generating their own personal supply of electricity. We suggest getting one wind […]
