Created by an IB Assistant Examiner, this Guided Experiment / Lab Guide includes everything you and your students need for completing the IB Required Practical 4: Chromatography (Separation of photosynthetic pigments by chromatograph). IBDP Biology Teachers can use this Guided Investigation to support students as they: Organise the equipment and materials needed to separate plant photosynthetic pigments. Conduct a plant chromatography experiment to produce a chromatogram. Use their chromatogram to calculate the retardation factor for each pigment (Rf). Use the calculated Rf factor and the included table to identify the pigments in the leaves of the plant. Also suitable for other curriculum programs - any kind of High School Biology course that focuses on scientific inquiry, such as AP Biology or Honors Biology. Skill (from IB Biology Guide): Separation of photosynthetic pigments by chromatograph. This Guided Lab Investigation has everything you need to prepare your IB SL and HL students to be ready to answer the many plant chromatography questions on the IBDP Biology Examination. Features: Key Terms Clear subheadings and sections Bullet Points for clarity Printable Ready to use List of related IB Exam question numbers from past papers Rf formula and explanation of how to use Clear diagrams showing experiment set-up Data table for student use Save yourself time - don’t recreate the wheel. Ready to use as-is with no effort needed from you, other than lab prep! All my resources are informed by my more than two decades experience teaching IB DP Bio, so you can be sure you are getting the right information.

Created by an IB Assistant Examiner, this 12-page Lab Guide provides full instructions for completing the IB Required Practical 3 (Enzyme Experiment), with everything students need to the practice skills required for writing their Internal Assessment (IA). IBDP Biology teachers can use this enzyme experiment guide to assign their SL and HL students the IB required practical, as it guides students through the laboratory experiment and the writing of a scientific investigation (lab report) which meets the IB Assessment Criteria: Exploration, Analysis, Evaluation, and Communication. Skill: Experimental investigation of a factor affecting enzyme activity. This experiment guide has everything you need for your students to be successful in their IA. No other resources are required (other than laboratory materials and equipment). This would also be suitable for any other High School Biology curriculum with a focus on scientific investigation, such as Honors Biology or AP Biology.

Created by an IB Assistant Examiner, this 7-page Guided Practice with microscopes and magnification provides full instructions for completing the IB Required Practical 1 (Using Microscopes, and Magnification Calculations). Includes sample problems to prepare your students for IB Biology Exams. IBDP Biology Teachers can use this Guided Practice to support DP Bio SL and HL students as they: Prepare and view microscope slides of onion cells and human cheek cells (i.e. plant and animal cells). Solve magnification calculations using the included images with scale bars and rulers, the magnification formula, and the step-by-step problem-solving process. Skills (from IB Biology Guide): Use of a light microscope to investigate the structure of cells and tissues, with drawing of cells. Calculation of the magnification of drawings, and the actual size of structures and ultrastructures shown in drawings or micrographs. This Guided Practice has everything you need to prepare your students to be ready to answer the many magnification questions on IBDP Biology Examinations. This would also be suitable for any other High School Biology curriculum with a focus on scientific investigation, such as AP Biology or Honors Biology. Features: Key Terms Links to helpful videos Clear subheadings and sections Bullet Points for clarity Printable Ready to use Five Practice Questions with guided steps Useful unit conversions Clear illustrations with rulers and scale bars Complete Answer Key

28 NO-PREP two-minute Brain Breaks you can use as back to school ice breakers, energizers, mindfulness breaks, movement breaks etc. in Middle School and High School, or Upper Elementary. Project the PowerPoint and click on the built-in spinner to select a random Brain Break. Help students refocus and relax, as well as get to know each other and have fun! Great as a classroom management tool and a way to build community, as well as increase student wellbeing. Use in any class, for any subject - the Brain Breaks contain a range of activities linked to many subjects. When your students appear tired and lacking in focus, just take a two-minute break to get them ready to learn again. These brain breaks are tried-and-tested by my Middle School and High School students. They love them - perfect when students just need a quick mental break or a chance to take a breather. You can even use them with adults to wake them up during meetings! The PowerPoint is editable so you can replace some slides if you wish. You must use this slideshow with PowerPoint - the spinner does not work on Google Slides. Be sure to click ‘slide show’ and then the play/pause button on the spinner What’s Included: 28 Brain Break Slides (each with Home button to return to spinner) Spinner/Randomizer Slide Simple, short instructions on each slide (no pages and pages of text to read!) Varied types: movement breaks, mindfulness, art, writing, games, drama, math and more! Mix of co-operative activities and individual activities Tried-and-tested brain breaks that aren’t ‘cringe’ (according to my MS and HS students) I have used these almost daily with my students from Grade 6 to Grade 12. They are always a hit!
